Abstract
Buffalo (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 ( χ 2 = =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.
