Pathomicrobial studies on Escherichia coli infection in bovine

Pathomicrobial studies on Escherichia coli causing bovine mortality in Haryana state was undertaken on 30 bovine carcasses. A total of nineteen serotypes of E. coli were identified from various visceral organs, among which O12 and O60 were most predominant and associated with severe pathogenic lesions. The isolates revealed maximum sensitivity to amikacin. Pathological studies of various serotypes of E. coli revealed perihepatitis alongwith pericellular cirrhosis, serofibrinous pneumonia, haemorrhagic/catarrhal enteritis, vascular changes in kidneys, myocarditis and fibrinous pericarditis.
