Infection ratewas 22.29, 28.33, 17.08 and 12.75%, respectively in slaughter-house buffaloes, livestock farm buffaloes,veterinary hospital buffaloes and household buffaloes. Overall the season wise the highest prevalence(28.33%) was recorded in buffaloes at livestock farms followed by slaughtered (22.29%) and veterinaryhospital buffaloes (17.08%). While the lowest (12.75%) prevalence was recorded in household buffaloesduring spring. It was also observed that the higher infection rate was recorded in younger buffaloes (belowtwo years of age) than older (above two years of age) where as sex wise the prevalence indicated that malebuffaloes were more commonly affected than females.
