AbstractIn this study, we found unsporulated coccidia oocysts in passerines from the Nevado de Toluca National Park, Mexico. We captured birds and took samples of their droppings during three field visits. We examined a total of 72 fecal samples and found unsporulated coccidia oocysts in 10 samples from five passerine species: Atlapetes pileatus (3), Cardelina ruber (1), Mniotilta varia (1), Oreothlypis celata (2) and Regulus calendula (3). This appears to be the first recorded study of unsporulated coccidia oocysts in passerine species from Mexico

A survey of coccidia in the Rocky Mountain bighorn sheep (Ovis. c. canadensis) in Alberta and Kootenay National Park, British Columbia, was conducted from the winter of 1967 to the spring of 1969. Ninety percent of 510 fecal samples examined were positive for coccidia. The species recovered, in order of prevalence, were Eimeria ovina (syn., E. arloingi) (56%), E. parva (35%), E. crandallis (34%), E. ahsata (33%), E. ninakohlyakimovae (19%), E. faurei (6%), E. intricata (5%) and E. granulosa (1%). Coccidiosis was not encountered in the field; however, evidence which suggests the magnitude of pathogenic infections is presented.

Sri Lanka is home to four species of wildcats: Leopard, Fishing Cat, Rusty-spotted Cat and Jungle Cat.  All four, except the Jungle Cat, are listed threatened.  A coprological survey was carried out in 2014 to determine the gastrointestinal (GI) parasites of wild and captive cats in Sri Lanka.  Parasite eggs and cysts were isolated and morphologically identified using iodine smears and a modified salt flotation.  The intensity of infection was quantified using a McMaster counting technique.  A total of 45 fecal samples were analyzed.  Except for the six captive Rusty-spotted Cats, all cats were infected with one or more GI parasites.  The presence of Moniezia sp. in Leopards in the Horton Plains National Park with an intensity of 150–1850 EPG (eggs per gram of feces) was unexpected.  Moniezia is a common GI parasite of ruminants and before our study it had never been recorded in Leopards.  Cross species infection with Moniezia could be possible due to accidental ingestion of cysticercoid infected oribatid mites, the intermediate host which could have been picked up in the pasture while feeding on carcasses.  Among the other parasitic infections in Leopards Toxocara was most common (61.9%) followed by strongyle infections (15.4%).  Of the fecal samples collected from wild Leopards 80.0% were infected with GI parasites while no GI parasites were found in the captive Leopard samples.  The Jungle Cats and the Rusty-spotted Cats sampled were in captivity and only the Jungle Cats were infected with strongyles.  Toxocara was recorded in Leopards and Fishing Cat both in captivity and in the wild.  It is a common GI infection of cats causing morbidity in all age groups and mortality in young animals.  Although parasitic infections of cats may not be a direct reason for a species’ decline, parasitic infections spreading within a small fragmented population could reduce the vitality and numbers and threaten the population further.  This is the first report of GI parasites of wildcats of Sri Lanka and the first record of Moniezia infections in Leopards.

This study was carried out to determine the prevalence of gastrointestinal parasites of musk deer in Langtang National Park, Nepal. A total of 9 fecal samples were collected systematically and analyzed using standard procedures during May-June, 2014. Overall 7 species of parasites including 4 nematodes, 1 cestode, 1 trematode and 1 protozoan parasite were recorded. Prevalence of Ascaris sp. was high (88.89%) followed by Eimeria sp. (77.78%), Trichuris sp. (66.67%), Strongyloides sp. (55.56%), Moniezia sp. (44.44%), Strongyle (44.44%) and Paramphistomum sp. (44.44%). Most of the samples had heavy parasitic infestation and multiple parasites were also observed in same individual. The high parasitic prevalence might have adverse health impact on musk deer. The possibility of cross-transmission of parasites between livestock and wildlife in Langtang National Park should be studied in future.Journal of Institute of Science and TechnologyVol. 21, No. 1, 2016, Page: 71-75

AbstractUsing a sedimentation method, the prevalence of the nodular worm Oesophagostomum stephanostomum (Nematoda: Strongylida) in western lowland gorillas at Moukalaba-Doudou National Park (MDNP), Gabon, was determined in fecal samples collected between January 2007 and October 2011, along with their coprocultures. Concurrently, possible zoonotic Oesophagostomum infections in villagers living near MDNP were assessed from their fecal samples collected during October and November of 2011. In the gorillas, strongylid (Oesophagostomum and/or hookworm) eggs were found in 47 of 235 fecal samples (20.0 %) and Oesophagostomum larvae were detected in 101 of 229 coprocultures (44.1 %). In the villagers, strongylid eggs were found in 9 of 71 fecal samples (12.7 %), but no Oesophagostomum larvae were detected in coprocultures. The internal transcribed spacer (ITS) region of ribosomal RNA gene (rDNA) and cytochrome c oxidase subunit-1 (cox-1) region of mitochondrial DNA (mtDNA) of coprocultured Oesophagostomum larvae were amplified using parasite DNA extracted from 7–25 larvae/sample, cloned into Escherichia coli, and sequenced. Sequenced rDNA contained 353/354-bp long ITS1, 151-bp long 5.8S rDNA, and 227-bp long ITS2. Parts of clones showed variations at 1–3 bases in the ITS1 region at a frequency of 24/68 (35.3 %) and at 1–2 bases in the ITS2 region at a frequency of 7/68 (10.3 %), whereas the 5.8S rDNA was essentially identical. Sequenced cox-1 gene of the parasites, 849 bp in length, showed a higher number of nucleotide variations, mainly at the third nucleotide position of the codon. The majority of clones (27/41 (65.9 %)) had an identical amino acid sequence. These results suggest that at MDNP, Gabon, only a single population of O. stephanostomum with a degree of genetic diversity is prevalent in western lowland gorillas, without zoonotic complication in local inhabitants. The possible genetic variations in the ITS region of rDNA and cox-1gene of mtDNA presented here may be valuable when only a limited amount of material is available for the molecular species diagnosis of O. stephanostomum.

Background and Aim: Gastrointestinal parasites identified in the wild can negatively affect host fitness, lower performance, and growth. On the other side, sympatric mammals that share habitat and resources may also cross-transmit parasites, which are often zoonotic and can contribute to morbidity and mortality. This study aimed to characterize the diversity of gastrointestinal parasites circulating in mammalian hosts in Moukalaba-Doudou National Park. Materials and Methods: We screened a total of 25 fecal samples collected from nine wild mammalian species, namely, western gorilla (Gorilla gorilla gorilla), chimpanzee (Pan troglodytes), putty-nosed monkey (Cercopithecus nictitans), African forest elephant (Loxodonta cyclotis), African buffalo (Syncerus caffer), blue duiker (Philantomba monticola), bay duiker (Cephalophus dorsalis), and red river hog (Potamochoerus porcus) as well as people working as trackers (Homo sapiens) using direct microscopic observations following a sedimentation technique to concentrate the fecal material. Results: Of the total 25 fecal samples screened, 15 (60%) were positive for parasitic gastrointestinal infection. Based on the morphology of parasite eggs and cysts, we identified a rich diversity of nematodes, protozoans, trematodes, and cestodes, including unidentified strongyles (73%), Oesophagostomum spp. (53%), Ancylostoma spp. (27%), Trichuris spp. (13%), Ascaris spp. (13%), Mammomonogamus spp. (13%), Strongyloides spp. (47%), Balantidium coli (20%), Entamoeba coli (20%), Endolimax nana (6%), Fasciola hepatica (6%), Paramphistomum spp. (13%), and Taenia spp. (6%). Conclusion: All parasites were found at least once in one of the hosts, and most were potentially zoonotic and responsible for several diseases of public health concern. Because of the small sample size, our findings should not be considered conclusive. Nevertheless, they highlight the diversity of gastrointestinal parasites in this area.
