Prevalence of Eggs of Three Trematode Genera (Fasciolaspp,Dicrocoeliumspp and schistosoma spp) In Buffaloes of Satungal Slaughter House, Kathmandu

Abstract

A studyon the prevalance of trematodes in buffalo was conductedin Satungal, Kathmandu during the period of December 2006-January2007. A total of 210 stool samples were collected during the study periodand examined employing sedimentation method. The overall prevalenceof helminth parasite was found 61.90%. Significant difference was foundin theprevalence ofthree genera oftrematode infection among buffaloes.The parasitic infections of Fasciolaspp was 38.57%,Dicrocoeliumspp18.10% and ofSchistosomaspp 28.10%.Single infection (infection withone species) wereobserved among 8.57%. Mixed infections of differentgenera of trematodes (Fasciolaspp,Dicrocoeliumspp andSchistosomaspp) were also observed and was found in 14.76%. It was noticed that ahigher infection rate was recorded in buffaloes above 2 years (71.65%)than buffaloes below 2years (46.99%). Most of the buffaloes examinedduring the present survey had low to moderateFasciola, SchistosomaandDicrocoeliumegg counts suggesting that the infections were usually sub-clinical. Pseudoparasites were also observed among 23 (10.95%) positivesamples. No work regarding these pseudo parasites was found.
