Item Coprological Survey of Gastro-Intestinal Helminth in Buffalo (Bubalus bubalis) of Dhrampur, Dhanusha, Nepal(Department of Zoology, 2015) Sah, Prabhaw KumarBuffalo (Bubalus bubalis), an important species of domestic livestock, is generally affected by helminth parasites. Present study was carried out to find the prevalence of gastrointestinal helminth parasites of buffaloes. Out of a total of 300 fecal samples collected 150 each during summer and winter season, were tested for the presence of gastrointestinal helminths using sedimentation and flotation techniques and the parasites were identified morphologically under microscope. The test revealed 74% and 84.66% positive for the presence of eggs of gastrointestinal helminths for the winter and summer season respectively. The fecal samples showed the prevalence of trematodes (47.01%), cestodes (2.66%) and nematodes (10.66%) during winter season. Likewise, the helminth eggs of trematodes, cestode and nematodes were 52.99%, 3.66% and 12 % of respectively during summer. Among the trematodes, Fasciola sp showed a a higher (23.33%) prevalence followed by Paramphistomum (17.66%) and Dicrocoelius (9.66%). Among cestodes, the only eggs detected belonged to Monezia (6.33%) sp. Among nematodes Trichostrongylus sp showed a higher (9.33%) prevalence followed gradually by Toxocara (5.66%), Strongyloides (2.66%), Trichuris (1.66%), Ostertagia (1%), Haemonchus (0.66%), Chabertia (0.66%), Cooperia (0.33%), and Capillaria (0.33%) spp. The parasite eggs were identified morphologically under microscope. The different in the prevalence of positive and negative samples were found statistically insignificant ( χ2= =51.62, P <0.05, d.f. =14). Single infection was observed in 216 (90.76%) samples, moderate infection in 14 (5.88%) samples and heavy infection 8 (3.66%) samples.Item A Preliminary Coprological Study on Helminth Parasites in Cattle (Bossp.) of‘Anarmani Vdc 02’jhapa(Department of Zoology, 2008) Dhakal, Krishna PrasadAltogether 200 dung samples of cattle (Bos sp.) were collected within two seasons viz,summer and winter from "Anarmani VDC 2" of Jhapa district. Thesamples were collectedequally from two seasons and both the sexes. Present study revealed prevalence of 55.55%nematodes, 33.33% trematodes and 11.11% cestodes among 151 (75.5%) positive samples.49 numbers (24.4%) of samples remains negative. Prevalence differs between ages,seasons and sexes to some extent. In general maximum infection was found by nematodegenera viz,Trichostrongylus sp., Strongyloides sp., Toxocara sp. trematode genera viz,Fasciolasp.,Dicrocoeliumsp,Schistosomasp. etc and cestode genera viz.Dipylidiumsp.and Monieziasp.Trematode generaHistophilussp. was reported for the first time inNepal among cattle, buffaloes, goats and sheep. Among the total positive samples 14%were found to have single infection and rest 86% have multiple infection by 2–5 differentgenera. The prevalence in general percentage follows as :Nematodes:Trichostrongylussp. (23.63%),Chabertia sp. (2.54%), Strongyloides sp. (7.77%),Toxocara sp. (4.93%),Ostertagiasp. (4.11%),Trichonemasp. (6.43%),Bunostomumsp. (0.82%),Dictyocaulussp (1.34%), Hookworm (0.89%),Haemonchussp. (3.66%),Ascarissp. (0.89%),Trichurissp. (1.78%), Cooperia sp. (0.074%), Capillaria sp. (0.29%), Oesophagostomum sp.(0.37%),Trematodes:Dicrocoeliumsp.(5.38%),Fasciolasp.(6.13%),Paramphistomumsp. (4.11%), Gastrothylax sp. (1.27%), Skrijabinema sp. (2.46%), Schistosoma sp.(5.38%),Histophilus sp. (2.24%),Fischoederius sp. (0.074%) andOrnithobilharzia sp.(1.12%). Cestodes:Moniezia sp. (3.88%), Taenia sp.(0.14%) and Dipylidium sp.(8.15%). Significant difference was found in prevalence among three classes of intestinalhelminths. KEY WORDS:Nematodes, Cestodes, Cattle, Trematodes, Prevalence & Jhapa.Item Prevalence of Gastrointestinal Parasites in Buffalo (Bubalus bubalis) in Malarani Rural Municipality of Arghakanchi, Nepal(Department of Zoology, 2023) Chhetri, BasantiThe primary component of Nepal's agricultural system and a substantial contributor to the country's economy is livestock. Buffaloes are one of the main types of livestock grown in Nepal. Total 200 fecal samples were collected in order to determine the prevalence and distribution of gastrointestinal parasites in buffaloes of Arghakhanchi, Nepal. The samples were microscopically examined by direct wet mount, sedimentation, and floatation techniques. One or more intestinal parasites were detected in 125 (62.5%) of the samples. Female buffaloes (58.5%) had a higher frequency of parasitic infection than male buffaloes (4%). Among the 200 samples, 60 were collected from young buffaloes and 140 from adults. Age wise prevalence of parasitic infection indicated that 32% in young and 68% in adult buffaloes were found infected. Adult buffaloes had a significantly high parasitic infection compared to young one ((χ2=16.20, df=1, p<0.05). Protozoan parasites Eimeria and Entamoeba were found equally common in young and adult buffaloes. Trematodes including Fasciola, Paramphistomum, and Eurytrema, which are helminths, were more abundant in adult buffaloes. Except for Ascaris and Capillaria, other nematodes had a higher prevalence in adult buffaloes. Only adult buffaloes were found to be infected with cestode parasite. Buffaloes of Malarani rural municipality were found to be highly infected with Ascaris sp and Entamoeba sp belonging to helminth and protozoan parasites respectively. Ward wise parasitic prevalence rate indicated that the distribution of parasitic prevalence was not significant (χ2=1.216, df=2, p>0.05). Overall parasitic prevalence showed protozoa (42.50%), nematodes (37%), trematodes (15.50%), and cestodes (1%) infection in buffaloes of study area. Overall, ten different parasitic infection was found in buffaloes of Malarani rural municipality with high prevalence indicating urgent need of intervention programms.Item Seasonal Prevalence of Gastro-Intestinal Helminth Parasites of Goats (Capra Sp.) of Shivraj Municpality-13 Kapilvastu, Nepal(Central Department of Zoology Institute of Science and Technology Tribhuvan University Kirtipur, Kathmandu, 2015) Tripathi, Rabindra PrasadGoat (Capra sp.), being an important source of meat in Nepal. This species is greatly affected by the helminthes parasites. The current study was carried out to observe the seasonal prevalence of intestinal parasites with sedimentation and flotation techniques. The samples were collected and examined for the study periods. The overall prevalence of helminth parasite during winter, 58 (54.71%) infection and summer 86 (81.13%) infection.

The current study was carried out to find out the seasonal prevalence of intestinal helminth parasites in buffaloes. Sedimentation and floatation both technique were used during the detection of helminth parasites. The samples were collected in two seasons i.e. during summer and winter. A total of 250 stool samples were collected and examined during the study period i.e. 120 samples in winter and 130 samples in summer. The overall prevalence of helminth parasites during winter were (45.83%) and that in summer season were (88.46%). A huge difference in the prevalence of helminths parasites in the both seasons were observed. During winter season the buffaloes were found to be infected with trematodes 31.66%, cestodes 10% and 32.5% nematodes. Likewise 67.69%, 11.53% and 56.15% of infections were caused by Trematodes, Cestodes and Nematodes respectively during summer season. The overall prevalence percentage of identified genera of trematodes are as follows; Fasciola 29.41%, Paramphistomum 11.76%, Dicrocoelium 12.94%, Schistosoma38.23%, Gastrothylax 2.35%, Fischoederius 1.17%, Ornithobilharzia 0.58% and Skrjabinema 5.29% respectively.Among cestode, the overall prevalence percentage of identified genera was found to be Moniezia 15.88% .Similarly the genera included in nematodes are Strongyloides 13.52%, Trichostrongylus 5.88%, Toxocara 34.11%, Ascaris 18.23%, Chabertia 1.76%, Trichuris 5.88%, Dictyocaulus 0.58%, Oesophagostomum 1.17%, Capillaria 1.17%, Haemonchus 1.76%, Ostertagia 2.94%, and Cooperia 0.58%. Single infection was found in 40% samples during winter and during summer it was found in 14.78% samples. Mixed infections was observed in 60% and 85.21% in the samples of winter and summer respectively.The difference in the prevalence of helminth parasites during both seasons were found statistically significant. ( χ² = 740.15, P<0.05, d.f. =21).Item A Study on Intestinal Helminth Parasites of Goats (Capra Hircus) Brought to Khasibazar, Kalanki (Kathmandu) for Slaughter Purpose(Department of Zoology, 2007) Parajuli, LaxmiCapra hircus (goat) is one of the important species of domestic livestocks in Nepal. The helminthic diseases are most varied and common in goat. Present study was carried out to find the prevalence of intestinal helminth parasites in goat. Both sedimentation and floatation technique were used for the detection of helminth parasites. A total of 222 stool samples were collected during the study period (November, December-2006 and May-2007) and examined. The over all prevalence of helminth parasite was found to be 81.53%. There is significant difference in prevalence of trematode, cestode and nematode infection among goats. The infection with trematodes was 13.96%, with cestodes 8.56% and with nematodes 76.13%. Nematode genus Dioctophyma is reported here for the first time from Nepal. No work regarding this genus from other host also has been found. Cestode genus Taenia, Trematode genus Dicrocoelium and Nematode genera Oxyuris and Capillaria have been reported from various hosts like cattle, horse, buffalo, pig and poultry but not from goat. So Taenia, Dicrocoelium, Oxyuris and Capillaria are also reported here for the first time from the host goat in Nepal. The trematode genera identified with their prevalence percentage was found to be Dicrocoelium 5.85%, Fasciola 5.40% and Paramphistomum 2.70%. Among cestodes, the prevalence percentage of identified genera was found to be Moniezia 5.40% and Taenia 3.15%. Nematodes include Strongyloides 9.45%, Haemonchus 19.36%, Trichostrongylus 17.56%, Ostertagia 9.00%, Oesophagostomum 8.11%, Cooperia 4.05%, Nematodirus 5.4%, Dioctophyma 2.25%, Dictyocaulus 2.7%, Chabertia 14.86%, Oxyuris 0.9%, Ascaris 3.15%, Toxocara 1.80%, Bunostomum 0.9%, Trichuris 5.85% and Capillaria 2.25%. Single infection was observed among 51 positive samples and maximum due to Haemonchus. Mixed infections were observed among 130 positive samples. Among Trematodes, the heavy infection was found due to Fasciola, among Cestodes, due to Moniezia and among Nematodes, due to Chabertia.
