ivermectin in African elephants (Loxodonta africana): implications for
parasite elimination
73. J. Zoo. Wildl. Med. 40, 107-112.
Abstract: Loxodonta africana are susceptible to a wide variety of
parasites that are often treated with the broad spectrum antiparasitic
ivermectin (IVM) based on empirical knowledge. The objectives of this
study were to 1) measure plasma IVM levels following administration of
0.1 mg/kg IVM p.o., 2) compare plasma IVM levels following
administration with regular versus restricted feed rations, 3) measure
IVM excretion in feces, and 4) use these findings to generate dosing
recommendations for this species. Using a crossover design, six African
elephants were divided into two groups. Ivermectin was administered and
typical grain rations were either provided or withheld for 2 hr. Blood
and fecal samples were collected for 7 days following drug
administration. After a 5-wk washout period, groups were switched and
the procedure repeated. Plasma and fecal IVM were analyzed using
high-performance liquid chromatography. There was no statistically
significant difference detected in the pharmacokinetic data between the
fed and fasted groups. Peak plasma concentration, area under the curve,
and half-life for plasma ranged between 5.41-8.49 ng/ml, 17.1-20.3 ng x
day/ml, and 3.12-4.47 day, respectively. High IVM concentrations were
detected in feces. The peak concentration values in feces were between
264-311-fold higher than those obtained in plasma. The comparatively
large area under the curve and short time to maximum concentration in
feces indicate elimination prior to absorption of much of the drug.
Plasma IVM concentrations were low when compared to other species. Based
on these findings, administration of 0.2-0.4 mg/kg p.o. should be
appropriate for eliminating many types of parasites in elephants, and
could minimize development of parasite resistance

Detection of Trypanosoma brucei in field-captured tsetse flies and
identification of host species fed on by the infected flies. Vector.
Borne. Zoonotic. Dis. 8, 565-573.
Abstract: The prevalence of trypanosome infections in tsetse flies in
the Chiawa area of Lower Zambezi in Zambia, with endemic trypanosomosis,
was determined by a polymerase chain reaction (PCR) method that allowed
the detection of trypanosome DNA and determination of the type of animal
host fed on by the tsetse fly Glossina pallidipes, using tsetse-derived
DNA extracts as templates. Ninety G. pallidipes (82 females and 8 males;
18.3%) of the 492 flies captured by baited biconical traps tested
positive for the presence of Trypanosoma brucei species genomic DNA. Of
the 90 T. brucei-positive flies, 47 (52.2%) also tested positive for
vertebrate mitochondrial DNA. Sequence analysis of the vertebrate
mitochondrial DNA amplicons established that they originated from 8
different vertebrate species, namely, human (Homo sapiens), African
elephant (Loxodonta cyclotis), African buffalo (Syncerus caffer),
waterbuck (Kobus ellipsiprymnus), roan antelope (Hippotragus equinus),
greater kudu (Tragelaphus strepsiceros), warthog (Phacochoerus africanus),
and goat (Capra hircus). Furthermore, to investigate the prevalence of
trypanosome infections in domestic goats in the same area where
trypanosomes had been detected in tsetse files, a total of 86 goats were
randomly selected from 6 different herds. Among the selected goats, 36
(41.9%) were found to be positive for T. brucei species. This combined
detection method would be an ideal approach not only for mass screening
for infection prevalence in tsetse populations, but also for the
prediction of natural reservoirs in areas endemic for trypanosomosis

American Journal of Tropical Medicine and Hygiene 79, 248-255.
Abstract: Fasciolid flukes are among the largest and best known
digenetic trematodes and have considerable historical and veterinary
significance. Fasciola hepatica is commonly implicated in causing
disease in humans. The origins, patterns of diversification, and
biogeography of fasciolids are all poorly known. We have undertaken a
molecular phylogenetic study using 28S, internal transcribed spacer 1
and 2 (ITS-1 and ITS-2) of nuclear ribosomal DNA, and mitochondrial
nicotinamide dehydrogenase subunit 1 (nad1) that included seven of the
nine recognized species in the family. The fasciolids examined comprise
a monophyletic group with the most basal species recovered from African
elephants. We hypothesize fasciolids migrated from Africa to Eurasia,
with secondary colonization of Africa. Fasciolids have been conservative
in maintaining relatively large adult body size, but anatomical features
of their digestive and reproductive systems are available. These flukes
have been opportunistic, with respect to switching to new snail (planorbid
to lymnaeid) and mammalian hosts and from intestinal to hepatic habitats
within mammals

and source of trypanosome infections in field-captured vector flies (Glossina
pallidipes) in southeastern Zambia. J. Vet. Med. Sci. 70,
923-928.
Abstract: The prevalence of trypanosome infections in tsetse flies,
Glossina pallidipes, collected from Chiawa and Chakwenga in Zambia with
endemic trypanosomosis was assessed by polymerase chain reaction (PCR).
Out of the 550 G. pallidipes, 58 (10.5%) flies were found to harbor
trypanosome DNA. Infection rates of tsetse with Trypanosoma vivax
universal, Trypanosoma congolense savannah, T. congolense forest and T.
congolense kilifi were 4.2% (23/550), 4.7% (26/550), 1.1% (6/550) and
1.6% (9/550), respectively. To determine the mammalian hosts of T.
congolense and T. vivax infections from the tsetse flies, mammalian
mitochondrion DNA of blood meal in these flies were analyzed by PCR and
subsequent gene sequence analysis of the amplicons. Sequence analysis
showed the presence of cytochrome b gene (cyt b) of 7 different
mammalian species such as human, elephant, buffalo, goat, warthog,
greater kudu and cattle. Goats which were main livestock in these areas
were further examined to know the extent of its contribution in
spreading the infection. We examined the prevalence of trypanosome
infections in the domestic goat population in 6 settlements in Chiawa
alone. Of the 86 goats sampled, 4 (4.6%), 5 (5.8%), 4 (4.6%) and 4
(4.6%) were positive for T. vivax universal, T. congolense savannah,
forest and kilifi, respectively. These findings showed that the
host-source of trypanosome infections in vector fly give a vital
information about spread of infection. The result of this study will
certainly contribute in elucidating more the epidemiology of
trypanosomosis

of "Rickettsia sp. strain Uilenbergi" and "Rickettsia sp. strain
Davousti" in Amblyomma tholloni ticks from elephants in Africa. BMC
Microbiol 7, 74 [Epub ahead of print].
Abstract: ABSTRACT: BACKGROUND: To date, 6 tick-borne rickettsiae
pathogenic for humans are known to occur in Africa and 4 of them were
first identified in ticks before being recognized as human pathogens.
RESULTS: We examined 33 and 5 Amblyomma tholloni ticks from African
elephants in the Central African Republic and Gabon, respectively, by
PCR amplification and sequencing of a part of gltA and ompA genes of the
genus Rickettsia. The partial sequences of gltA and ompA genes detected
in tick in Gabon had 99.1% similarity with those of R. heilongjiangensis
and 97.1% with those of Rickettsia sp. HL-93 strain, respectively. The
partial gltA and ompA gene sequences detected in tick in the Central
African Republic were 98.9% and 95.1% similar to those of Rickettsia sp.
DnS14 strain and R. massiliae, respectively. Phylogenetic analysis
showed Rickettsia sp. detected in Gabon clusters with R. japonica and R.
heilongjiangensis in a phylogenetic tree based on the partial gltA and
ompA genes. The genotype of the Rickettsia sp. detected in the Central
African Republic is close to those of R. massiliae group in the
phylogenetic tree based on partial gltA gene sequences, and distantly
related to other rickettsiae in the tree based on partial ompA gene.
CONCLUSIONS: The degrees of similarity of partial gltA and ompA genes
with recognized species indicate the rickettsiae detected in this study
may be new species although we could only study the partial sequences of
2 genes regarding the amount of DNA that was available. We propose the
Rickettsia sp. detected in Gabon be provisionally named "Rickettsia sp.
stain Davousti" and Rickettsia sp. detected in the Central African
Republic be named "Rickettsia sp. strain Uilenbergi".

Seroprevalence of Toxoplasma gondii antibodies in captive elephants (Elephaus
maximus maximus) in Sri Lanka
516. Veterinary Parasitology 137, 172-174.
Abstract: Serum samples collected during August 2003-June 2004 from 45
privately owned captive and 8 elephants from the Pinnawala Elephant
Orphanage were tested for the presence of antibodies against Toxoplasma
gondii using the direct modified agglutination test (MAT). Antibodies
were found in sera of 14 of 45 (32%) privately owned elephants with
titers of 1:25 in three, 1:50 in three, 1:100 in three, 1:200 in three,
and 1:400 in three elephants. The elephants from Pinnawala Elephant
Orphanage were seronegative. This is the first report of T. gondii
seroprevalence in elephants in Sri Lanka
Penzhorn, B.L.,
2006. Babesiosis of wild carnivores and ungulates
499. Veterinary Parasitology 138, 11-21.
Abstract: Although large and small piroplasms have been reported from
various wild carnivore and ungulate species, relatively few have been
named. In the past, mere presence of a piroplasm in a specific host
frequently prompted naming of a new species. Descriptions were often
inadequate or lacking altogether. Currently, demarcation of species
relies heavily on molecular characterisation. Even serological evidence
is deemed insufficient. Experimental transmission of Babesia spp. from
domestic to wild animals is usually only successful in closely related
species, or after splenectomy. There are indications that endemic
stability, similar to the situation in livestock, is the general pattern
in Babesia sp. infections in wildlife. All lions in Kruger National Park
were found to be infected with B. leo, which did not lead to clinical
disease manifestation in artificially infected lions. Under stressful
conditions, infections could flare up and be fatal, as purportedly
happened to the famous lioness "Elsa". Similarly black rhinos, which can
harbour Babesia bicornis without ill effects, may develop clinical
babesiosis during confinement after capture. Zoo-bred animals, which
were not exposed to Babesia spp. at a young age, may be fully
susceptible when released into a natural environment where other members
of their species occur. This could have major implications for ex situ
conservation programmes aimed at bolstering natural wildlife populations

succession of dung beetles associated with Indian elephant dung in South
Western Ghats forests
524. J. Insect Sci. 6, 1-12.
Abstract: The diversity, guild structure and succession of dung beetles
associated with Indian elephant dung is described in a deciduous forest
site in Western Ghats, a hot spot of diversity in India. Dung beetles
were collected using baited pitfall traps and from exposed dung pats in
the forest at intervals of 1, 3, 5, 7, 15 and 21 days. Twenty-one dung
beetle species belonging to the 3 major functional guilds were recorded.
Abundance of dwellers was high compared to rollers deviating from
earlier reports on the high abundance of rollers in the afrotropical
regions. Dweller Drepanocerus setosus and tunneler Onthophagus bronzeus
were the most abundant species. Dung pats aged 3-5 days attracted the
highest abundance of dung beetles. Bray Curtis similarity index
indicated low community similarity between different stages of
succession. Species richness and abundance of tunnelers increased with
dung age and decreasing moisture up to a threshold level, followed by a
decrease. Rollers and dwellers did not show any significant relationship
with dung moisture content. Further research is needed to estimate the
dung beetle community associated with the dung pats of other mega
herbivores as well as of elephant dung in other forests of the Western
Ghats

2006. New filarial nematode from Japanese serows (Naemorhedus crispus:
Bovidae) close to parasites from elephants
403. Parasite 13, 193-200.
Abstract: A new onchocercid species, Loxodontofilaria caprini n. sp. (Filarioidea:
Nematoda), found in subcutaneous tissues of 37 (33%) of 112 serows (Noemorhedus
crispus) examined in Japan, is described. The female worm had the
characteristics of Loxodontofilaria, e.g., the large body size,
well-developed esophagus with a shallow buccal cavity, and the long tail
with three caudal lappets. The male worm of the new species, which was
first described in the genus, had unequal length of spicules, 10 pairs
of pre- and post-caudal papillae, and three terminal caudal lappets.
Deirids were present in both sexes. Among four species of the genus
loxodontofiloria: one from the hippopotamus and three from the
Elepantidae, L. caprini n. sp. appears close to L. asiatica Bain, Baker
& Chabaud, 1982, a subcutaneous parasite of Elephas indicus in Myanmar
(Burma). However, L. caprini n. sp. is distinct from L. asiatica in that
the Japanese female worm has an esophagus half as long and the
microfilariae also half as long with a coiled posterior. The
microfilariae were found in the skin of serows. The new parasite appears
to clearly illustrate a major event in the evolution of onchocercids:
the host-switching. This might have occurred on the Eurasian continent,
where elephantids and the lineage of rupicaprines diversified during the
Pliocene-Pleistocene, or in Japan, into which some of these hosts
migrated

Mukaratirwa, S., 2005. Seroprevalence of Toxoplasma gondii in
farm-reared ostriches and wild game species from Zimbabwe. Acta Trop 94,
49-53.
Abstract: One hundred and seventy one serum samples from 10 game species
from Zimbabwe were tested for IgG antibodies to Toxoplasma gondii
infection using the modified agglutination test (MAT). Significantly
higher seroprevalences were found in the felidae (Panthera leo) (92% of
26), bovidae (Tragelaphus species) (55.9% of 34)and farm-reared
struthionidae (Struthio camelus) (48% of 50) compared to the other
groups tested. Among the bovidae, the nyala (Tragelaphus angasii) had
the highest seroprevalence of 90% (9/10). Anti-Toxoplasma antibody
prevalences in browsers [greater kudu (Tragelaphus strepsiceros) (20% of
10), giraffe (Giraffa camelopardalis) (10% of 10) and elephant
(Loxodonta africana) (10% of 20)] were generally in the lower range. No
antibodies were detected in the wild African suidae [warthog (Phacochoerus
africanus) and bushpig (Potamochoerus larvatus)]. Attempts to isolate T.
gondii from the heart muscles of seropositve ostriches by subinoculation
in BALB/c mice were unsuccessful.

Molecular taxonomic position of the elephant schistosome,
Bivitellobilharzia nairi, newly discovered in Sri Lanka
745. Parasitol. Int. 53, 69-75.
Abstract: Bivitellobilharzia nairi (Mudaliar and Ramanujachar, 1945)
Dutt and Srivastava, 1955 was first recorded in India. A number of adult
worm specimens of this schistosome species were recovered from a
domestic elephant, which died in 1999 in Sri Lanka. This is the first
report of this schistosome from Sri Lanka. In the present study, in
order to clarify the phylogenetic relationship with other species of
schistosomes, sequences from the second internal transcribed spacer
(ITS2) of the ribosomal gene repeat, part of the 28S ribosomal RNA gene
(28S), and part of the mitochondrial cytochrome c oxidase subunit 1
(CO1) gene from B. nairi were analyzed. Two intraspecific variations
were seen within 13 individuals in the ITS2 region. In the CO1 region of
the mitochondrial DNA, there were four haplotypes in the nucleotide
sequences and two haplotypes in the amino acid sequences. Phylogenetic
analysis using the nuclear DNA showed that B. nairi was basal to all of
species of the genus Schistosoma. The 28S tree also showed that the
mammalian lineage was monophyletic. However, phylogenetic analysis using
the mitochondrial DNA showed that B. nairi was nested within the genus
Schistosoma. The taxonomical position for this species as well as the
contradiction between the results from the nuclear and mitochondrial
genes were discussed

Abstract: Forty-five privately owned captive, apparently healthy
elephants were blood sampled in order to detect the presence of
antibodies against Toxoplasma gondii during August 2003- June
2004. The elephants were from 5 of the 11 districts in which, captive
elephants live at present. Blood samples were transported in ice to the
laboratory, serum separated immediately and frozen until analysed. A
direct modified agglutination test was performed on serum. Sera of 14 of
45 (32%) elephants were found to be positive for the test. Highest titre
reported was 1:400. A significantly high number of females (11/14) were
positive for T.gondii antibodies compared with the male elephants
(P = 0.02). The differences in titres among the age groups of
elephants were not significant (P > 0.05). It appears that
Toxoplasmosis is common among the Sri Lankan captive Elephants.
Considering the nature of the infection, the sero-positive animals could
become clinically diseased when immune-compromised, such as observed in
the case of tuberculosis. Elephants, may have contacted this disease
through faecal contamination from wild, semi wild or domestic animals.
The fate of the parasites within elephant's body and investigating the
possibility of elephants infecting humans or other animals may be of
importance. This is the first report on presence of antibodies to
T.gondii infection in elephants in Sri Lanka

forest elephants (Loxodonta africana cyclotis) from the Republic of
Congo and Central African Republic. Comparative Parasitology 71 ,

Abstract: Fecal samples were collected from 6 African forest elephants,
Loxodonta africana cyclotis, from the Nouabale-Ndoki National Park,
Republic of Congo, and the Dzangha-Sangha National Park, Central African
Republic. One of the elephants was found freshly dead from natural
causes, and 12 species of intestinal parasites (2 bot fly larvae, 1
trematode, and 9 nematodes) were collected during a complete necropsy.
In addition, fecal samples revealed the presence of a schistosome,
Bivitellobilharzia sp., a tracheal nematode, Mammomonagamus sp., and a
complex of intestinal strongylids and ciliates. The nematode genera
Decrusia and Equimurbia are reported for the first time from African
elephants, and the ciliate genus Latteuria is reported for the first
time from wild elephants. The parasite fauna of the African elephant is
discussed in the light of recent genetic evidence that the forest and
savannah elephants may be separate species.

2004. Oribatid mites as intermediate hosts of Anoplocephala manubriata,
cestode of the Asian elephant in India
726. Exp. Appl. Acarol. 32, 181-185.
Abstract: Anoplocephala manubriata (Cestoda: Anoplocephalidae) is a
tapeworm that parasitizes both African (Loxodonta africana) and Asian
(Elephas maximas) elephants. Its life cycle has not yet been completely
elucidated nor have intermediate hosts been previously reported. Soil
and substrate was collected in the Kodanadu Forest Range, Ernakulum
District and Guruvayur Devaswom Temple grounds, Thrissur District, in
Kerala, India. Oribatid mites (Acari: Oribatida) were collected from
dung piles near captive elephants' bedding and examined for immature
stages of the tapeworm. Five species of oribatids were found to contain
at least one immature life stage of A. manubriata: Galumna flabellifera
orientalis Hammer 1958, Scheloribates latipes (C.L. Koch 1844), S.
praeincisus (Berlese 1913), Protoribates seminudus (Hammer 1971), and P.

captive elephants. Zoos' Print Journal 19, 1422.
Abstract: This study was conducted to determine the prevalence of
parasitic infections among captive elephants in Guruvayoor town in
Kerala, India. Dung samples were collected from 44 and 55 elephants
during 2000 and 2002, respectively, and examined for the presence of
helminth ova. Of the 99 elephants, 17 (17.17%) were positive for
helminths. The incidence of helminth infection decreased from 22.73% in
2000 to 12.73% in 2002. Among the positive dung samples, 10 (10.10%) had
Strongylidae and 7 (7.07%) had Digenea. The low incidence of helminth
infection among captive elephants in the studied area might be due to
the regular annual deworming using albendazole (2.5 mg/kg body weight).

animals at Thekkady in Kerala. Zoos' Print Journal 18, 1030.
Abstract: Helminth infection is wide spread in wild animals and may
cause mortality and morbidity of varying degrees. Gour et al.(1979) and
Fowler(1986) have stated that the wild animals in the free-living state
are generally infected with numerous parasites, but cause little harm to
them, unless they are streesed. Therefore, understanding the rate of
infection in wild animals is important since infections could result in
massive die-offs of wild animals during extreme stress conditions. There
are several reports of parasitic infection in zoo animals, but
information of the same in free- living wild animal scanty. This paper
reports the parasitic infection in four wild boars, a calf elephant, a
sambar deer and a leopard cat which died at Thekkady forest area in
Kerala. The parasites collected during post mortem by the first author
were preserved in formalin and brought to College of Veterinary and
Animal Sciences, Mannuthy. The specimens were washed, dehydrated,
cleared in creosote and eexamined for specific identity.
All the parasites found in wild boars except Gastrodiscoides hominis
and Gnathostoma hispidum commonly infect the domestic
pig(Soulsby, 1982). Noda(1973) has reported Ascaris suum from
Sus scrofa lucomystax while Henry and Conley(1970) recorded
Physosephalus sexalatus from European wild hogs. Occurrence of
Amblyoma sp.(ticks) in wild boars is recorded by Rajagopalan et
al.(1968). Herbivores and rodents are the common intermediate hosts of
Lingutula serrata, which in the adult stage occur in carnivores.
Available literature did not reveal the occurrence of larvae of this
parasite in Sambar. The elephant calf was heavily infected with
strongyle worms and maggots of Cobboldia elephantis and is quite
likely that its death may be due this infection. Sundram(1966) has
recorded all these parasites from captive elephants. The Leopard Cat was
also heavily infected with Echinococcus granulosus causing
enteritis which probably could have contributed to its death.

Abstract: The earliest writing describing the diseases of elephants in
ancient literature said to be the works on "Gajasastra" (Elephantology)
written in Sanskrit by authors like Gautama, Narada, Mrigacharma,
Rajaputra and Vyasa. "Hasthyayurveda" a legendary book in Sanskrit
written by a safe Palakapya deals with some diseases, treatment,
desirable and undesirable points of selection, management practices and
some mythological aspects on the origin of elephants. The earliest book
in English dealing with diseases of elephants seems to be that of W.
Gilchrist "A practical treatise on the treatment of diseases of
elephants" published in 1848. Later Slym (1873), Sanderson (1878), Steel
(1885), Evans (1910), Herpburn (1913), Milroy (1922), Ptaff (1940),
Ferrier (1947), Utoke Gale (1974), Chandrasekharan (1979) and Panicker
(1985) have documented their findings on the incidence, etiology and
control of diseases of Asian elephants.

Transmission dynamics of Cryptosporidium in primates and herbivores at
the Barcelona zoo: a long-term study. Vet Parasitol 104, 19-26.
Abstract: Factors influencing the transmission of Cryptosporidium in
primates and herbivores housed at the Barcelona zoo have been analyzed.
The relationship between continuous and discontinuous oocyst shedding,
both animal housing conditions and abiotic factors (seasonality,
humidity, temperature) was examined to explain the epizootiology of the
protozoan. Thirty six fecal samples from each of 11 primates (Pongidae,
Cebidae, Cercopithecidae and Lemuridae) and 22 herbivores (Elephantidae,
Camelidae, Cervidae, Giraffidae and Bovidae) were examined over the
period of 1 year. The parasite transmission was based on the chronic
infection status of some animals serving as a source of successive
reinfection for other animals. The environmental temperature and
humidity (seasonality), the physical features of the facilities, the
vicinity of the animals and the physiological status induced by
captivity contributed to transmission. The long-term character of this
study was essential for obtaining these results and interpreting the
complex relationships.

R. Soc. Lond. B 269, 2041-2049.
Abstract: Habitat loss and the resultant fragmentation of remaining
habitat is the primary cause of loss of biological diversity. How do
these processes affect the dynamics of parasites and pathogens? Hess has
provided some important insights into this problem using metapopulation
models for pathogens that exhibit 'S-I' dynamics; for example, pathogens
such as rabies in which the host population may be divided into
susceptible and infected individuals. A major assumption of Hess's
models is that infected patches become extinct, rather than recovering
and becoming resistant to future infections. In this paper, we build
upon this framework in two different ways: first, we examine the
consequences of including patches that are resistant to infection;
second, we examine the consequences of including a second species of
host that can act as a reservoir for the pathogen. Both of these effects
are likely to be important from a conservation perspective. The results
of both sets of analysis indicate that the benefits of corridors and
other connections that allow species to disperse through the landscape
far outweigh the possible risks of increased pathogen transmission. Even
in the commonest case, where harmful pathogens are maintained by a
common reservoir host, increased landscape connectance still allows
greater coexistence and persistence of a threatened or endangered host.

Japanese Journal of Zoo and Wildlife Medicine 7, 145-148.
Abstract: A louse (Haematomyzus elephantis) infection was found on the
epidermis of 3 Asian elephants (Elephas maximus) in captivity. Although
each elephant showed heavy itching sensation with scratching of bodies
on the wall or ground in the facility, no bruises or papules on their
bodies were observed. The local treatment by dipping using a synthetic
pyrethroid liquid was ineffective. Good expulsion was attained with the
treatment with a carbaryl-based shampoo 5 to 7 times during more than 2
months. It is necessary to inspect for louse infections of imported
elephants in zoos at the time of quarantine.

southern India. J Biosci 27, 521-528.
Abstract: Some ecological factors that might potentially influence
intestinal parasite loads in the Asian elephant (Elephas maximus Linn.)
were investigated in the Nilgiris, southern India. Fresh dung samples
from identified animals were analysed, and the number of eggs/g of dung
used as an index of parasite load. Comparisons across seasons and
habitats revealed that parasite loads were significantly higher during
the dry season than the wet season, but were not different between the
dry-deciduous and dry-thorn forests in either season. After accounting
for the effect of age on body condition, there was no correlation
between body condition, assessed visually using morphological criteria,
and parasite load in either season. Individuals of different elephant
herds were not characterized by distinct parasite communities in either
season. When intra-individual variation was examined, samples collected
from the same individual within a day differed significantly in egg
densities, while the temporal variation over several weeks or months
(within a season) was much less. Egg densities within dung piles were
uniform, enabling a simpler collection method henceforth.

Abstract: Three Indian elephants (Elephas maximus) in Thailand were
treated with mebendazole at a dose of 6-7 mg/kg body weight. Four days
following treatment, faecal examinations were negative for nematode eggs
in all elephants and negative for fluke eggs in two of the animals.
However, adult parasites were recovered from faeces from each of the
animals 36-72 hours after deworming. These included Murshidia falcifera,
M. neveulemairei, a Quilonia species, and the amphistome Pfenderius
papillatus, 1910. The finding of P. papillatus constitutes the first
record of this species in Thailand. Specimens of P. papillatus were
examined by scanning electron microscopy. In contrast to earlier
descriptions of this species, no prominent papillae were found at the
anterior end. Structures on the acetabulum that had previously been
described as papillae were actually elevated pores that were spread over
the acetabulum. These pores differ from all previous descriptions of P.
papillatus and indicate a highly modified acetabulum in P. papillatus
relative to other Pfenderius species.

Abstract: Under laboratory conditions, larvae of Murshidia sp. revealed
high motility until 4 months and maintained moderate motility until 7
months. In comparison, larvae of Quilonia sp. and Decrusia sp. displayed
a high degree of motility during the first 2 months, but this
subsequently declined. These observations suggest that, under in vitro
conditions, strongylid larvae from captive Asiatic elephants of the
Chennai region may survive for 4 to 7 months.

Epidemiological and clinico-therapeutic studies of strongylosis in
elephants. Zoos' Print Journal 16, 539-540.
Abstract: Elephants like other herbivores are susceptible to various
diseases including internal parasitism. In Nehru Zoological Park (NZP),
Hyderabad, India, clinical records of Asian Elephants for a period of 10
years (1987-96) were examined to determine the prevalence of
strongylosis in relation to season, age and sex. Faecal samples from
elephants of S.V. Dairy Farm (SVD), Tirupathi, were also screened from
January to June for helminthosis. Faecal egg counts (EPG) were estimated
by Stoll's dilution method. Analysis of old records revealed that in NZP
strongylosis was predominant in summer (52.63%) and the prevalence was
lower in animals below 15 years of age. Seven animals (63.64 and 87.5%)
each tested positive for ova of strongyles in NZP and SVD, respectively.
On treatment with albendazole (Kalbend, 5 mg/kg BW, PO), the animals
completely recovered on the seventh day. Therapy resulted in decreases
in the pretherapeutic mean EPGs of 700±128.89 (SVD) and 671.4±123.20 (NZP)
to 78.57±30.53 and 50±21.79, respectively. The animals were monitored up
to four weeks after therapy.

antibodies to T. gondii using the modified agglutination test (MAT) and
the latex agglutination test (LAT). Antibodies to T. gondii were found
in 45.5% of 156 elephants by MAT (_1:50) and 25.6% of 156 elephants by
LAT (_1:64). This is the first report of T. gondii infection in E.
maximus indicus from Asia.

interspecific body size principle in ungulates: the smaller they come,
the harder they groom. Animal Behaviour 60, 35-45.
Abstract: Tick removal grooming may be centrally regulated by an
internal timing mechanism operating to remove ticks before they attach
and engorge (programmed grooming model) and/or evoked by cutaneous
stimulation from tick bites (stimulus-driven model). The programmed
grooming model predicts that organismic and environmental factors that
impact the cost-benefit ratio of grooming (e.g. body size and habitat)
will influence the rate of tick removal grooming. The body size
principle predicts that smaller-sized animals, because of their greater
surface-to-mass ratio, should engage in more frequent tick removal
grooming than larger-bodied animals in order to compensate for higher
costs of tick infestation. The body size principle may be tested
intraspecifically between young and adult animals, or interspecifically
among species of contrasting body sizes. To rigorously test the
interspecific body size prediction, we observed the programmed grooming
(oral and scratch grooming) of 25 species (or subspecies) of bovids at a
tick-free zoological park in which stimulus-driven grooming was ruled
out. Multiple correlation analysis revealed highly significant negative
correlations between species-typical mass and mean species grooming
rates when habitat was controlled for in the model. Species-typical
habitat type (classified along a gradient from most open to most closed)
was positively correlated with mean oral grooming rate, indicating that
species tended to groom at a higher rate in woodland and forest habitats
(where typical tick density would be high) compared with more open
environments. Species mass accounted for up to two-thirds of the
variation in grooming rate across species, whereas habitat accounted for
ca. 20% of variation in oral grooming. Similar results were obtained
when the analysis was expanded to include 36 species/subspecies of six
different families. The body size principle can therefore account for a
large proportion of species-typical differences in programmed grooming
rate among ungulates. However, to understand the tick defense
adaptations of very large mammals that rarely or never engage in oral or
scratch grooming (e.g. elephants, giraffes, rhinoceros), alternative
tick defense strategies must be considered, such as thick skin,
wallowing, rubbing and tolerance of oxpeckers and other tick-eating
birds.

Abstract: Summary of abstract: The epidemiology of Fasciola jacksoni in
wild and captive elephants (Elephas maximus) was studied in Assam,
India. Wild elephants had an overall prevalence rate of 33.78%. Captive
elephants showed prevalence rates of 42.50, 62.28 and 18.18% according
to locality. The egg, miracidium and adult stages of F. jacksoni were
studied by light and scanning electron microscopy, and their morphology
is described. A diurnal fluctuation in faecal egg count was recorded,
with average counts of 4.89, 2.47 and 2.76 during the morning, noon and
evening, respectively. Young animals were most affected by the parasite
and showed anorexia, constipation, diarrhea, anaemia and icterus, with
death occurring in severe cases. Some old adults survived the disease
with no apparent clinical manifestations. The adult parasites caused
massive liver damage. Treatment with triclabendazole (9 mg/kg, not
exceeding 7200 mg/animal) and oxyclozanide (7.5 mg/kg, not exceeding 6.8
g/animal) were 100 and 72.16% effective, respectively.

Abstract: Three new ciliate species presumed to belong to the family
Paraisotrichidae were recovered from faecal samples from Asian and
African elephants (Elephas maximus and Loxodonta africana) in Kiev,
Moscow and Warsaw zoos. As all the ciliates have a unique but similar
arrangement of somatic ciliature, a new genus Latteuria gen. nov. was
erected. The genus is characterized by the presence of a tapered frontal
"spout" at the anterior end of the body, posterior ciliary rows in
narrow grooves encircling the posterior half of the body and an anterior
arch of cilia. L. polyfaria sp. nov. (type species) from Loxodonta
africana in Moscow Zoo is the largest species in the genus with 9-11
posterior ciliary rows. In L. media sp. nov. from E. maximus in Kiev
Zoo, of medium body size, the number of rows varies from 4 to 6, and the
smallest species, L. trifaria sp. nov. from Loxodonta africana in Moscow
Zoo, has only 3-4 posterior ciliary rows.

gastrointestinal tract impaction of a 2-year-old Asian elephant (Elephas
maximus). Australian Veterinary Journal 73, 37-38.
Abstract: The case of a 2-year-old Asian elephant (E. maximus) with
gastrointestinal impaction caused by ingesting sand and clay is
reported. The sand was the basic substrate of the elephant's enclosure
at Perth Zoo, Australia, and the clay had been added as a top-dressing.
The behaviour was thought to have been the result of salt deficiency in
the elephant's diet, and once this had been rectified and the impaction
treated, she stopped ingesting sand. There were 3 other elephants in the
enclosure and although they ingested sand, they did not suffer from
impaction. Segments of Anaoplocephalus sp. [Anoplocephala sp.] were
found in her faeces, and this infection had probably been picked up from
a 36-year-old elephant in the enclosure which was known to be infected.

Parasitology 32, 205-210.
Abstract: Stephanofilaria thelazioides sp. nov. is described and figured
from an ulcerated skin lesion on a hippopotamus Hippopotamus amphibius
from the Kruger National Park, South Africa. This nematode is closely
related to S. dinniki, a parasite of the black rhinoceros Diceros
bicornis in Africa, but differs from it in the number of cuticular
spines surrounding the mouth, the arrangement of the cloacal papillae
and the measurements of the spicules, gubernaculum and microfilariae.
Species of the genus Stephanofilaria possess spines on the head which
have been derived by modification of the sensory papillae. S.
thelazioides is the most primitive species of the genus and has the
least modified arrangement of these papillae, with 6 bifid internal
labial spines, 4 bifid external labial spines and 4 cephalic papillae.
The genus appears to have diversified in various mammals which have in
common a thick skin, such as rhinoceroses, elephants, buffaloes and now
the hippopotamus. It appears to have become adapted secondarily to
domestic bovines, initially in Asia and subsequently in North America.

International Seminar on Asian Elephants. Bombay Natural History
Society; Oxford University Press, Bombay, India, pp. 439-449.
Abstract: Incidence, etiology, symptoms and control of specific and
non-specific diseases of captive and wild elephants have been reviewed.
Asian elephants have been observed to be susceptible to various
parasitic diseases such as helminthiasis, trypanosomiasis and
ectoparasitic infestations, bacterial diseases such as tetanus,
tuberculosis, haemorrhagic septicemia, salmonellosis and anthrax, viral
diseases such as foot and mouth disease, pox and rabies and non-specific
diseases like impaction of colon, foot rot and corneal opacity. A
detailed study extending over two decades on captive and wild elephants
in Kerala, revealed high incidence of helminthiasis (285), ectoparasitic
infestation (235), impaction of colon (169) and foot rot (125). Diseases
such as trypanosomiasis (21), tetanus (8), tuberculosis (5) pox (2) and
anthrax (1) were also encountered. The line of treatment against the
diseases mentioned, have been discussed in detail.

southwestern Kenya, by NG2G traps during the dry season of 1992. Of
these, 339 individuals (11.1%) had blood meals, of which 155 (45.7%)
were identified by direct ELISA. The most frequent blood meal source was
bushbuck (Tragelaphus scriptus), followed by ostrich (Struthio camelus),
elephant (Loxodonta africana), buffalo (Syncerus caffer) and warthog (Phacochoerus
aethiopicus). Few meals were taken from cattle. The finding of frequent
blood meals from ostriches is new for G. pallidipes and may indicate
that ostriches are an important host. More detailed work on the role of
ostriches in the epidemiology of trypanosomiasis is required.

(Ciliophora, Entodiniomorphida) from Asian elephant, Elephas maximus and
African elephant, Loxodonta africana. Journal of Protozoology Research 5,
157-175.
Abstract: Intestinal ciliate compositions in faecal samples from 3
zoo-kept Asian elephants (Elephas maximus) (Kiev and Moscow zoo and
Berlin Tierpark) and 1 African elephant (Loxodonta africana) (Moscow
zoo) were examined. The elephants had all been born in the wild. Eleven
new ciliate species belonging to the genus Triplumaria are described.
Four of the new species possessed honeycomb-like thick skeletal plates
and broad linear skeletons which were present in T. hamertonii (type
species) and T. selenica. The anterior location of the micronuclei in T.
selenica also occurred in these 4 new species. However, 2 species
possessed long macronuclei with the posterior end either curved
ventrally (T. longinucleata n. sp.), or straight and extended into the
tail lobe (T. nucleocaudata n.sp.). T. asiatica n. sp. had 2 bulb-like
and one cylindrical caudalia; hill-like caudalia of T. heterofasciculata
n. sp. were clearly characteristic in size. Six new species possessed
thin light skeletal plates and slender linear skeletons which showed
vertebra-like structure; T. antis n. sp. was small in body size and had
a micronucleus in the centre of the macronucleus, whereas the other
species had micronuclei located anteriorly; T. doliiformis n. sp. was
characterized by an anteriorly hooked macronucleus; T. acuticaudata n.
sp. had a triangular tail lobe; T. dvoinosi n. sp. possessed antero-dorsal
and ventral caudalia directed up and downward. The antero-dorsal
caudalium of T. ovina n. sp. was shifted upwards and the ventral
caudalium of T. irregularis n. sp. was shifted to the left. T.
poljanskii n. sp. was characterized by a combination of heavy
honeycomb-like skeletal plate, vertebra-like linear skeleton and the
posterior location of the micronucleus. T. acuticaudata and T.
nucleocaudata were identified in Loxodonta africana, whereas the
remaining 9 species were identified in Elephas maximus.

J.C. (Ed.), A Week with Elephants; Proceedings of the International
Seminar on Asian Elephants. Bombay Natural History Society; Oxford
University Press, Bombay, India, pp. 289-295.
Abstract: The helminth parasites of free ranging as well as captive
elephants of the Mudumalai Wildlife Sanctuary were studied
quantitatively by analysing over 200 dung samples and 7 autopsy
examinations. The prevalence and intensities of infection were high in
both captive as well as wild elephants. The helminth communities of both
were, however, species poor as compared to other mammalian host species.
The high prevalence and intensities are thought to be related to the
absence of predation and the low species diversity may be a result of
absence of other closely related host species. The age and sex of
individuals sampled did not affect their parasite loads significantly.
The faecal propagule densities were significantly greater during the dry
season as compared to the wet season. Stronglid nematodes of the genus
Quilonia dominated the helminth communities. Tapeworm infection
was significantly greater in captive elephants than the wild ones. The
possible reasons for this difference are discussed.

Abstract: Microscopic examination of thin smears, an ELISA, and kit for
in vitro isolation of trypanosomes (KIVI) were compared for diagnosis of
trypanosomiasis in 3 elephants, 53 African buffaloes, 12 roan antelope (Hippotragus
equinus), 9 hartebeest (Alcelaphus buselaphus), 19 waterbuck (Kobus
ellipisiprymnus), 61 Kob (Kobus kob), and 6 wart hogs (Phacochoerus
aethiopicus). In the 82 animals on which all 3 tests were carried out,
20% were positive by the thin smear method, 50% by the ELISA and 80% by
the KIVI test. The trypanosomes were probably T. brucei, T congolense
and T. vivax but these were not identified.

R., Braack, L.E.O., 1994. African horsesickness epidemiology: five
species of Culicoides (Diptera: Ceratopogonidae) collected live
behind the ears and at the dung of the African elephant in the Kruger
National Park, South Africa. Oderstepoort Journal of Veterinary Research
61, 155-170.
Abstract: During the culling of elephants (Loxodonta africana) at 5
sites in the Kruger National Park, South Africa, 682 Culicoides of 5
species of the subgenus Avaritia were found either living behind the
ears of elephants or attracted to the freshly disemboweled intestinal
dung of elephants. The species were Culicoides tororoensis, C. kanagai,
C. loxodontis, and 2 undescribed species, Culicoides sp. £50 and
Culicoides sp. £54 pale form (p.f.). Of 511 female midges found behind
ears, 39.9% were nulliparous, 57.3% empty parous, 2.5% freshly bloodfed
and 0.2% gravid. The age composition of this subpopulation indicates
that the Culicoides were behind the ears to suck blood and, furthermore,
would do so in broad daylight. The age composition of 171 Culicoides of
3 species attracted to dung was entirely different: 1.8% nulliparous,
14.6% empty parous, and 83.0% gravid, indicating that the great majority
of midges captured at dung were about to oviposit or had just oviposited.
Immediately after culling, light traps were operated at 2 of the sites.
Of 4023 Culicoides of 21 species captured, 93% were of the same 5
species found on the ears and at the dung of elephants. Using these and
other unpublished data pertaining to the rearing of these 5 Avaritia
species from elephant dung over the past 7 years, the life cycle of
these Culicoides is broadly sketched, the first for any Afrotropical
species of the genus. The implications that the close association
between elephant and midge has for the dispersal and geographic
distribution of the latter, and how it may influence the involvement of
midges in the transmission of diseases such as African horse sickness,
are also discussed. Owing to difficulties in identifying species of the
subgenus Avaritia in the Afrotropical Region, the taxonomy of each of
the 5 above-mentioned species is briefly appraised. Of the remaining 16
species (7%) captured in light traps, 15 (6%) belong to that sector of
the genus Culicoides whose immature stages develop in groundwater
habitats and include C. imicola, which comprised only 2% of the
light-trap collections. The large disparity in the adult abundance
patterns of the "dung" and "groundwater" species in the middle of dry
bushveld is probably the result of differences in host and larval
habitat preferences, and is briefly discussed. Finally, the few reports
extant on the wild-host preferences of Afrotropical Culicoides are
reviewed.

Abstract: F. jacksoni recovered from infected liver and lungs were
almost round, pear-shaped measuring 10-16 mm in length and 8.5-14 mm in
width with ill-defined cephalic end between indistinct shoulders. The
intestine was extensively branched. The yellowish tinged ova were oval
with an operculum at one end and measured 0.112-0.160 (mean 0.13) mm in
length and 0.054-0.096 (mean 0.07) mm in width. Infected liver showed
haemorrhagic tracts, thickening of bile ductules, cirrhotic changes and
pseudolobulations. In the lungs, the bronchial lumen contained
desquamated cells admixed with fibrinohaemorrhagic exudate.

sangeri (5 females, 9 males) are reported for the first time in
Malaysia. Both were found in Elephas maximus hirsutus, the former
species in an 8-year-old female in a zoo in Perak, and the latter in a
one-year-old male belonging to the State Wildlife and National Parks
Department in Pahang. The worms are described and figured. The elephant
infected with Q. travancra had exhibited signs of anorexia but recovered
after anthelmintic treatment. The carcass of the elephant infected with
B. sangeri appeared generally pale and anaemic; on post-mortem
examination the contents of the stomach and small intestine were loose
and watery and filled with B. sangeri.

Abstract: The labial palpus of H. elephantis has 6 sensilla that
represent 3 different types: trichoid, basiconic and styloconic. Two
rows of basiconic sensilla are situated on the dorsal and central
surfaces of the rostrum, and each row consists of 3 sensilla. Male and
female antennae have 15-17 trichoid sensilla situated on the scape,
pedicel and 3 antennal annuli. Both sexes have 2 sensilla basiconica on
the dorsal surface of the pedicel near the junction of the scape and
pedicel. Two coeloconic sensilla are situated on the antenna of both
sexes, one sensillum on each of the last 2 annuli. There are 3 plate
organs, 2 on the last annulus and 1 on the penultimate annulus of the
male and female antennae. Sexual dimorphism is exhibited in the male and
female antennae, in that the male has about twice as many sensilla
basiconica on the apex of the last annulus as does the female. The total
number of sensilla basiconica on the apex of the male antennae is at
least 2 times the number that is known to be present in any other
species of lice.

elephants. Indian Journal of Veterinary Pathology 16, 98-101.
Abstract: Fasciola jacksoni infection was discovered in 2 out of 3
elephants autopsied at Assam State Zoo, India, during 1985 to 1989. The
parasites were attached to biliary epithelium. Microscopy demonstrated
that the biliary epithelium was distorted by necrotic tissue which
contained erythrocytes and ova of F. jacksoni. The epithelium was
analyzed by X-ray microanalysis, which showed that the infected
epithelium contained aluminum, silicon, calcium and iron, while
non-infected, normal biliary epithelium contained only phosphorus and
sulfur. Scanning electron microscopy demonstrated that both the dorsal
and ventral surfaces of the parasite possessed spines.

Abstract: Summary: A case of toxicity in a 2 year old elephant treated
with 1 liter of Nilverm (300 g of Tetramisole is presented.
Clinical symptoms included muscular tremors, salivation, initially
diarrhoea followed by constipation and bradycardia. Treatment with
dextrose, B complex, atrophine sulfate and liquid paraffin resulted in
alleviation of symptoms and slow improvement. The authors comment that:
"tetramisole itself has a safety margin variously estimated to be 2-6
times the therapeutic dose of 15 mg/kg and the safety factor of
levamisole is about twice that of the parent compound since levamisole
is equally active against parasites in half the dosage."

with the African elephant in the Kruger National Park, South Africa.
Onderstepoort Journal of Veterinary Research 59, 145-159.
Abstract: Culicoides (Avaritia) loxodontis sp. nov., is described and
illustrated from both sexes collected in South Africa. It is the 5th
species of the Imicola group of the subgenus Avaritia to be described
from the Afrotropical Region, and is presently known only from the
Kruger National Park where it has been collected in light-traps and
reared from the dung of the African elephant (Loxodonta africana) on
various occasions. A number of character states, and statistical
analyses of antennal and palpal measurements, are used to separate the
new species from its taxonomic congeners C. imicola Kieffer, 1913, C.
pseudopallidipennis Clastrier, 1958, C. bolitinos Meiswinkel, 1989 and
C. miombo Meiswinkel, 1991. It is suggested that the occurrence of the
African elephant is the primary factor that determines the distribution
of Culicoides loxodontis sp. nov., and that this close association,
coupled with the fact that C. loxodontis sp. nov. can be locally
abundant, may result in the cycling of certain arboviruses between this
biting midge and the elephant

Abstract: Tsetse populations and trypanosome infections were monitored
at the Ngulia Rhino Sanctuary, Kenya, to assess the impact of
trypanosomiasis on rhinoceros (Diceros bicornis). High densities of
Glossina pallidipes were found near a permanent spring by the Ngulia
escarpment (96.3% of the 3204 tsetse caught during the main drug season
survey of 1990); G. longipennis and G. brevipalpis were also present in
lower numbers. Infection rates in G. pallidipse averaged 3.6%, with 3
times as many Trypanosoma vivax (2.21%) as T. congolense (0.88%)
infections (also found were T. brucei, in 0.03% and immature infections,
in 0.46%). A similar infection rate was found in G. longipennis (1.58%
T. vivax, 0.53% T. congolense, 1.05% immature). T. simiae and T. brucei
were present at low frequency. None of the 7 G. brevipalpis dissected
was infected. DNA probes revealed that all mature T. congolense
infections belonged to the Savanna subgroup. G. pallidipes fed on many
hosts, with most meals taken from bovids and elephants. Rhino accounted
for one of the blood meals in a small sample taken from G. longipennis.
During a time of low tsetse densities (dry season), it was estimated
that the wild host population was acquiring 7 infections per km/day. At
lower levels of challenge, an experimental rhino became infected with T.
congolense. These results are discussed in terms of future plans for the
repopulation of rhino in tsetse-infested areas in Kenya.

weights of these elephants were calculated using the formula: weight
(kg) = 12.8 (n+ng) -4281, where g is chest girth (cm) and ng is neck
girth (cm). A drug containing 25% fenbendazole was given orally at a
dosage of 5 mg/kg. One elephant had diarrhoea and was also given
astringent. No eggs were detected after 7 days in 2 cases and after 14
days in all 3 cases.

Abstract: Pathology of Fasciola jacksoni infection in the bile
duct of elephant have been reported by gross histopathology, Scanning
electron microscopy (SEM) and Energy dispersive X-ray micro-analysis (EDAX).
SEM Study of the parasite was also attempted. Grossly, the parasites
were found attached in the biliary epithelium and microscopically, the
epithelial surface of the bile duct was covered by a necrotic
homogeneous mass admixed with erythrocytes. The liver parenchyma
adjacent to the bile duct, was replaced by fibrous tissue
proliferation. SEM showed distortion of biliary epithelium which turned
into a homogeneous mass. The infected biliary epithelium was analysed
through EDAX and the values were compared with biliary epithelium of
unaffected animal. The infected epithelium contained aluminium, silicon,
calcium and iron while in normal biliary epithelium only phosphorous and
sulphur could be noticed.
On SEM study both the dorsal and ventral surface of the parasite
contained spines.

Abstract: Sudden change in behaviour of six elephants was observed
violent in nature did not permit their use for tourist. They were losing
their condition. Anorexia, pyrexia, and anemia vis-a-vis the infected
elephants were lethargic,eyes shrunken with lacrimation and they became
unresponsive to command. Disintegrating trypanosomes in elephants of
Kanha National Park were diagnosed by blood sample. NSD findings were
reported by other diagnostic laboratories. Chemotherapy with corridane
(Hindustan antibiotic) was done. An elephant of average build was
injected with 12.5 gms of corridane dissoved in 75 ml of dist. water
subcutaneously. A single injection was effective for 3 months. In
recurrent the above dose need to be repeated. Berenil (Hoechst) @ 800
mg/ 100 kg body weight by deep IM route, revealed synergistic effects.
Livferol 250 ml B.D. 15 days effectively managed anaemia and deranged
liver function. Sugar cane was supplemented to check hypoglycaemia. Six
elephants simultaneously affected were cured. Half dose of corridane has
chemoprophelectic effect. Rehydration was done with 3 kg of Gur, common
salt 510 gms, fresh water 60 liters for 4-5 days.

Abstract: Certain features of the morphology of adult males and females
of H. elephantis are figured in 20 SEM micrographs, and described. The
specimens were from an Asian elephant (Elephas maximus) from Burma in
Chongqing Zoo. The distribution of the sensory setae and campaniform
organs on the legs, the existence of sexual dimorphism of the sensory
pegs on the apical part of the 5th antennal segment, the abdominal
scales with a serrated edge, and the phallic sac of the male with 2
types of sensory pores are all described for the first time. Several
errors in the literature are corrected, especially concerning the
mouthparts and antennal sensilla. The mouthparts of H. elephantis differ
from those of either the Anoplura (described functionally as piercing)
or Mallophaga (chewing). It is suggested that the mouthparts of H.
elephantis are not homologous with those of Mallophaga (the suborder in
which H. elephantis is placed by some authorities) but instead that they
represented a unique piercing type. Arguments are put forward to raise
the suborder Rhynchophthirina (represented by this single species,
according to other authorities) to ordinal rank, for which the name
Rhynchophthiraptera is proposed.

Isospora felis, Paragonimus westermani and Taenia pisiformis were also
found in winter. Ancylostoma sp. was found in leopard cubs, and ascarids
in lion cubs. More than 1 helminth species were not usually found
together. Strongyles were found in elephants and a cestode in a python.
A slothbear, Himalayan bear, Russian bear and white and black monkeys
were negative for helminth parasites.

Atractidae), a parasite of the African elephant. Systematic Parasitology
14, 135-140.
Abstract: Leiperenia moreli sp. nov. from 12 Loxodonta africana from
Gona-Re-Zhou National Park, Zimbabwe, differs from Leiperenia leiperi in
its measurements (smaller body length and longer male genitalia). These
2 species differ from L. galebi parasitizing elephants in India, by a
much larger female tail. The genus exhibits many original
characteristics: labial and cephalic papillae at the end of a peduncle,
an oesophagus with a subspherical anterior region and a club-shaped
posterior region, a dorsal tooth in the pharyngeal part of the
oesophagus, a longitudinal slit-like excretory pore, a monodelphic
female laying larvae by the "matricide endotokie" process, and a male
with several hypertrophied pyriform cloacal papillae. The most closely
related genus appears to be Grassenema, a parasite of Procavia, but the
differences between the 2 genera are very distinct. Genera belonging to
the family Atractidae may have had ancestors with a normal parasitic
life (without an endogenic cycle) which may have belonged to the
Cosmocercidae at one time, and the Kathlaniidae at another. The family
is thought to be paraphyletic.

Abstract: Clinical and laboratory findings are presented for a case of
chronic dermatitis in a 32-year-old female Asian elephant in Nandan
Biological Park, Barang. Lesions were observed on the toes and heels of
the hind feet and right abdominal wall, and microfilariae resembling
Stephanofilaria were present in skin scrapings and blood from the
lesions. Application of 8% metrifonate [trichlorfon] ointment in Himax
(right food and abdomen) or vaseline (left foot) daily resulted in
clinical cure after 15 days in lesions treated with Himax-based
metrifonate and 22 days with vaseline-based metrifonate.

Abstract: The results of blood-meal identifications for 651 Glossina
pallidipes from 5 subpopulations near the Kenya coast south of Mombasa,
and one, 70 km inland, are presented. Bushpigs [Potamochoerus porcus]
and/or warthogs [Phacochoerus aethiopicus] were important hosts for G.
pallidipes at all sites. Other major hosts included elephant [Loxodonta
africana], buffalo [Syncerus caffer] and bushbuck [Tragelaphus scriptus]
where present, and on a dairy ranch nearly 30% of feeds were taken from
cattle. There was a relation between the numbers and diversity of wild
herbivores and the abundance of G. pallidipes. These results are
discussed in relation to published data on feeding patterns and
trypanosome infection rates for G. pallidipes from other parts of East
Africa. Overall, there are significant correlations between the
proportions of bovid feeds and Trypanosoma vivax infections.
Bovid-feeding G. pallidipes populations with high T. vivax infection
rates in south-east Uganda and western Kenya contrast with the coastal,
suid-feeding populations with low T. vivax rates. These characteristics
are presented as clines extending across East Africa.

Abstract: Four species of Stephanofilaria have been reported from India
causing various forms of dermatitis in cattle, buffalo, goat and
elephant. However, additional work is needed to establish their identity
as separate species. The lesions appear to flare up following
reinfection, while the application of a petroleum jelly alone reduces
them. In vitro tests have shown organophosphorous compounds to possess
stephanofilaricidal action in addition to their insecticidal activity.
Aspects where further work is needed are indicated.

Abstract: Between January and April 1983, the Borgu sector of the Kainji
Lake National Park was visited and faecal droppings of several game
animals belonging to the groups of Carnivora, Artiodactyla, Proboscidae
and Primates were collected and processed for the presence of helminth
ova and larvae. Faeces were also collected from the rectum of domestic
ruminants which had grazed on the periphery of the park. Post mortem
examinations were conducted on a baboon and an adult Monitor Lizard.
Most of the game animals possessed multiple helminth infection but the
egg-counts were generally low. Larvae of Haemonchus, Oesophagostomum and
Trichostrongylus were common to wild and domestic ruminants while larvae
of hook- and lungworms were mostly restricted to carnivores and
primates. Some of the helminths found in the stomach and intestine of
baboon during post-mortem were of public health interest

Abstract: The evolutionary line of Dipetalonema can apparently be
divided into four groups: I: Australian species; II: paleoendemic South
American species; III: the Tetrapetalonema group; IV: the
Acanthocheilonema group. Loxodontofilaria at present insufficiently
known to be classified and several species belonging to the
Acanthocheilonema group are the object of the present study.
Descriptions are given of Loxodontofilaria asiatica n. sp., parasite of
Elephas indicus in Burma, Cercopithifilaria degraaffi n. sp., parasites
of Papio ursinus in South Africa, C. cephalophi n. sp., parasite of
Cephalophus dorsalis and C. gabonensis n. sp., parasite of Atherurus
africanus in Gabon. Additional morphological data are given on
Cercopithifilaria didelphis, C. rugosicauda, Acanthocheilonema
pachycephalum, A. viteae, Molinema dessetae, Dipetalonema gracile,
Orihelia sp., Skrjabinofilaria skrjabini, Breinlia (B.) spratti,
Litomosa sp., Loxodontofilaria hippopotami. Yatesia n. gen. with type
species Yatesia hydrochoerus (Yates, 1980), is proposed, distinguished
by specialized characters of the posterior extremity. The genus
Cercopithifilaria is used to accomodate species considered as
specialized Acanthocheilonema. Chenofilaria is placed in synonymy with
Acanthocheilonema. Loxodontofilaria includes the three filarid species
from elephants, L. loxodontis, L. gossi, L. asiatica n. sp. and the
species from the Hippopotamus, L. hippopotami; D. okapiae is considered
a species inquirenda. The interpretation given for the neotropical fauna
is the following: --Skrjabinofilaria, Orihelia, Dasypafilaria and
Dipetalonema may be true paleoendemics in South America. --Molinema and
Ackertia on the one hand and Yatesia on the other may be forms of
African origin introduced at the end of the Eocene during the migration
of African rodents into South America. The capture in American reptiles
(the genus Macdonaldius) could have occurred during this period.
--Surprisingly, the two species of Dipetalonema in Didelphis may be late
captures of neartic origin: A. pricei from Acanthocheilonema in
carnivores and C. didelphis from a Cercopithifilaria in eutherian
mammals.

after treatment.
Mohr, J.L.,
Jollie, K.G., Smith, T.P. Ciliates of elephant caecums. Journal of
Protozoology 29, 482. 1982.
Ref Type: Abstract
Abstract: On the basis of limited sampling, African elephants,
Loxodonta, appear to have more complex ciliate assemblages than
other cellulose-eating mammals. In caecal samples of five Kenyan
Loxodonta at least ten families are represented of which the
Kofoidian elephantophilae and some others have been found only in
Loxodonta and Elephas. One paraisotrichid genus, found in
both elephants, may be related to ciliates of hyracoid mammals. Some
cycloposthiids have be identified with species in hoofed mammals, but
most appear to be restricted to elephants. Except for Kofoid's original
Mysore collection, all Elephas materials studied have been from
zoological gardens; their assemblages have been much less varied than
those in wild Loxodonta. In the Loxodonta assemblage we
have tried to determine roles of various ciliates. There are obvious
cellulose ingesters, carnivores and bacteriovores, "vampires" (suctorians)
and presumably osmiotrophs, however, much cannot be determined from such
fixed materials. Current ciliate taxonomy appears to need revision to
accomodate some of the species.

Abstract: Severe submandidular and ventral abdominal edema was observed
in an Asian elephant (Elephas maximus) in which liver flukes (
Fasciola jacksoni) were recovered from the bile ducts at post-mortem
examination. Clinico-pathologic examination of blood samples and serum
from this elephant and another 8 elephants showed that most had anemia
and hypoproteinemia. Fecal samples from 6 of the elephants contained
from 6 to 83 eggs per gram. Treatment of elephants with nitroxynil (10
mg/kg) by subcutaneous injection produced severe local reactions at the
injection site. Feces collected 2 and 4 months after treatment were
free of trematode eggs. Hematologic values measured 4 months after
treatment showed that the hemoglobin concentration, packed cell volume,
erythrocyte count and plasma protein concentration had increased to
within the normal range.

funnel-shaped. There is a raised and transverse fissure ridge around the
oral margin. The internal wall of the buccal capsule is raised into a
series of circular ridges or lamellae. Teeth or cutting plates could not
be seen. Spicules are stout, wing-like structures. The telamon is
pear-shaped, but a gibernaculum is not present. There are two pairs of
papillae on the either side of the cloacal opening. The female tail is
gradually tapering.

20 (13%) were seropositive. T. gondii antibodies were detected in
Burchell's zebra, (Equus burchelli), hippopotamus (Hippopotamus
amphibius), African elephant (Loxodonta africana), defassa waterbuck (Kobus
defassa), lion (Panthera leo), and rock hyrax (Procavia capensis), The
highest titers were found in elephants, two having titers of 1:4096 and
one of 1:8192. These results are discussed in relation to the
maintenance of T. gondii among African wildlife.

Abstract: In Africa trichinosis is essentially a disease of wild
carnivores. Once established in a suilline cycle it becomes a more
important threat to man. The results of test of 8,000 specimens of 20
wildlife species in the Kruger National Park are discussed and the
epizootilogy of trichinosis in South Africa is briefly reviewed. The
first case of trichinosis in an African civet, Viverra vetta
Schreber, 1776, is reported. The confirmed absence of trichinosis in
true herbivores is of practical significance in view of the increasing
utilization of game meat as food.

Burchell's zebra, Equus burchelli antiquorum, buffalo,
Syncerus caffer, hippopotamus, Hippopotamus amphibius, and
impala, Aepyceros melampus. Infestation rates in the herbivores
vary from 60% in zebra to less than 1% in impala. Species like
elephant, Loxodonta africana, and blue wildebeest,
Connochaetes taurinus, do not seem to be susceptible. The
successful artificial transmission of Echinococcus granulosis felidis
from Bruchell's zebra to the lion is reported for the first time.
