Isolation, Antibiogram and Pathogenicity of E.Coli Associated with Calf Diarrhoea

R.P. Diwakar | R.K.Diwakar

Abstract: Total one hundred and twenty five fecal samples were collected from diarrhoeic calves under 3-6 month of age and 110 E. coli isolates were recovered. E. coli was found to be highly sensitive for Gentamicin and least sensitive against Cloxacillin. A total 110 isolates of E. coli were examined for congo red binding ability for studying the enteropathogenicity. Amongst 110 E. coli isolates tested, only 67 isolates (60.90 per cent) showed good congo red binding and were considered as enteropathogenic while, 43 isolates (39.09 per cent) were found to be negative i. e. non enterotoxigenic as no color was revealed by their colonies on congo red medium.
