Abstract

A cross sectional study was conducted from November 2014 to April 2015 in Dangila District, Awi Zone, Amhara National Regional State, Ethiopia, to determine the prevalence of Bovine schistosomosis and to identify the possible associated risk factors. Simple random sampling method was used to select the animals and coprological examination using sedimentation technique was applied for the recovery of Schistosoma eggs from freshly collected fecal samples and preserved in 10% formalin. Of the total 384 cattle examined, 44(11.5%) were found to be positive for Schistosoma bovis. there was no statistically significant difference observed among four kebeles; even though Dengesgta (16.3%) revealed the highest prevalence, while the lowest in Gumdrie (7.3%).
