Item Prevalence of Fascioliasis Present in Buffaloes of Slaughterhouse in Kirtipur Municipality(Central Department of Zoology, 2010) Shrestha, Anju200 slaughtered water buffaloes were examined. 100 were observed during the winter; from November 27, 2007 to February 10, 2008 and 100 were observed during the summer; from June 18, 2008 to July 26, 2008. Out of them, 93 (46.50%) were males and 107 (53.50%) were females. 54 (27%) of them were calves, 51 (25.50%) were adults and 95 (47.50%) were olds. Females were found more infected with fascioliasis. 38.05% of the females had fascioliasis as compared to 16.09% of males. The difference in sex-wise prevalence of fascioliasis was found significant (χ 2 0.05, 1d.f. =11.63). Old animals (35.78%) were infected with Fasciola more often than calves (14.81%) and (29.41%) adults. Difference in age-wise prevalence of Fasciola was significant (χ 2 0.05, 2d.f. =7.45). 35 and 22 positive cases of fascioliasis were observed out of 200 slaughtered animals observed, 100 each during winter and summer season. The season-wise prevalence of fascioliasis was found significant (χ 2 0.05, 1d.f. =4.14). Out of 35 positive cases of Fasciola infection observed during winter, 20 (57.14%) buffaloes had only Fasciola hepatica while 11 (31.42%) had only F. gigantica and 4 (11.42%) had both F. hepatica and F. gigantica. Similarly during summer, out of 22 animals that had fascioliasis, F. hepatica was found in 7 (31.81%) of them while F. gigantica was observed in 12 (54.54%) of them and 3 (13.63%) of them had both F. hepatica and F. gigantica. Infection with Fasciola hepatica (59.65%) was found slightly higher than Fasciola gigantica (52.63%). Faecal sample of 55 (27.50%) buffaloes were found positive for fascioliasis, out of 200 slaughtered buffaloes observed. 33 and 22 positive cases of fascioliasis were observed out of 200 slaughtered animals observed, 100 each during winter and summer season. Females were found more infected with fascioliasis. 37.14% of the females had fascioliasis as compared to 16.84% of males. Old animals (33.68%) were infected with Fasciola more often than calves (14.81%) and (29.41%) adults.Item A Study On Intestinal Helminth Parasites of Buffaloes Brought To Satungal (Kathmandu) For Slaughter Purpose(Central Department of Zoology Institute Of Science and Technology Tribhuvan University Kirtipur, Kathmandu Nepal, 2007) Mukhia, GouriBubalus bubalis (buffalo) is one of the leading species of domestic livestock in Nepal. The helminthic diseases are most varied and of common occurrence in buffaloes. Present study was carried out to find the prevalence of intestinal helminth parasites in 262 stool samples of buffaloes during July to August 2006.Both sedimentation and floatation technique were used for the detection of helminth parasites. A total of 262 stool samples were collected during the study period and examined. The overall prevalence of helminth parasites was found 83.96%. There is significant difference in the prevalence of trematode, cestode and nematode infections among buffaloes. The parasitic infection of trematode was 90.90%, cestode 14.54% and of nematode 49.09%. Trematodes, Dicrocoelium lanceatum and Ornithobilharzia turkestanicum are reported for the first time from Nepal. However, no work regarding these species have been reported from any host. Although trematode Skrjabinema ovis, Fischoederius elongatus and nematodes, Chabertia ovina, Dictyocaulus sp and Capillaria sp has been reported from various hosts sheep, cattle and goat but not reported from buffalo. So, S. ovis, F. elongatus, C. ovina, Dictyocaulus sp. and Capillaria sp. are reported for the first time from the host buffalo in Nepal. The trematode genus identified with their prevalence percentage are as follows; Fasciola sp. 32.06%, Paramphistomum sp. 15.64%, Dicrocoelium sp. 20.61%, Schistosoma sp. 46.94%, Gastrothylax sp. 0.76%, Fischoederius sp 0.38%, Ornithobilharzia sp. 0.76% and Skrjabinema sp. 6.87% respectively. Among Cestode, only Moniezia species was observed with infection rate 13.35%. Nematode included Strongyloides sp. 4.19%, Trichostrongylus sp. 1.90%, Toxocara sp. 22.90%, Ascaris sp. 6.87%, Chabertia sp. 0.38%, Trichuris sp. 2.29%, Dictyocaulus sp. 0.76%, Oesophagostomum sp. 0.76%, Capillaria sp. 0.38%, Haemonchus sp. 1.14%, Ostertagia sp. 1.52% and Cooperia sp. 0.76%. Mixed infections were observed among 140 positive samples. Among trematode, Dicrocoelium lanceatum and Fasciola hepatica found to be heavily infected. In cestode, Moniezia benedeni and nematode, Toxocara vitulorum found to be heavily infected in buffaloes.Item Trematode Infections in Aquatic Snails and Buffaloes: A Case Study of Ramgram Municipality, Nawalparasi, West Nepal(Department of Zoology, 2009) Kohar, NareshThe present study was conducted in Ramgram Municipality, Nawalparasi during July to October 2008. Freshwater snails were examined to determine the occurrence of larval trematodes and faecal samples of domestic buffaloes were examined for parasitic eggs. A total of 2921 freshwater snails belonging to eight (8) species were collected from temporary ditches and drainages along the road side. Altogether 92 (3.15%) snail individuals harboured patent trematode infections. Lymnaea sp. had the highest overall prevalence of infection 34 (7.26%), followed by Indoplanorbis exustus (3.08%), Segmentina sp. (3.03%), Gyraulus sp. (2.01%), Gabia orcula (1.60%). No parasite infection was recorded in Bellamya bengalensis, Bellamya dissimilis and Pila globosa. The most common six (6) morphotypes of cercariae were identified. They are Longifurcate-pharyngeate (Strigea) cercaria, Brevifurcate-apharyngeate (Schistosoma) cercaria, Brevifurcate-pharyngeate (Clinostomoid) cercaria Gymnocephalous (Fasciola) cercaria, Amphistome cercaria and Xiphidiocercaria. Examined 735 fecal samples of domestic buffaloes showed 189 (25.71%) of total samples were positive for faecal infection. Among positive infections, 146 (19.86%) samples contained trematode egg (Fasciola sp.) infection. Other remaining 43 eggs other than Fasciola were not confirmed and not specified during the study. The prevalence of Fasciola egg infection was maximum in September (38.09%) followed by August (26.98%), October (19.01%) and July (15.87%)
