A total of 340 samples were processed for estimating prevalence of E. coli. Out of those 340 samples tested, 68 E. coli isolates were recovered. All 68 E. coli isolates revealed typical cultural characters on the MacConkey agar and Eosin Methylene Blue agar. Some of the E. coli isolates showed variation from the standard biochemical pattern viz. fermentation of adonitol (1.47% isolates) and raffinose (22.05% isolates).enVeterinary Public HealthStudyThesis
