The prevalence of enterotoxigenic Escherichia coli in the feces of calves with diarrhea


, : The prevalence of enterotoxigenic Escherichia coli in the feces of calves with diarrhea. Canadian Journal of Comparative Medicine 40(3): 241-246

A study was undertaken to determine the prevalence of enterotoxigenicity among Escherichia coli isolated from calves with diarrhea and from a control group of normal calves. The test organisms consisted of 200 E. coli recovered from scouring calves less than two weeks of age and 100 E. coli from normal calves. The enterotoxigenicity of the cultures was evaluated by three methods, namely, injection of ligated segments of piglet intestine, injection of ligated segments of calf intestine and oral inoculation of suckling mice. Live cutures of all the test organisms were used for the ligated intestine studies whereas sterile broth culture supernatants were used in the suckling mouse tests. Of the isolates from scouring calves, 36% were enterotoxigenic in the piglet intestine and 28% in the calf intestine. Amongst the isolates from normal calves, none was enterotoxigenic in the piglet intestine and one was enterotoxigenic in the calf test system. The ligated piglet intestine was considered unsuitable for determining the enterotoxigenicity of bovine E. coli, whereas the ligated calf intestine test was satisfactory and correlated completely with the suckling mouse test. The enterotoxigenic E. coli of bovine origin produced an enterotoxin that resembled the heat stable enterotoxin of typical porcine enteropathogenic E. coli.
