Enteropathogenic (EPEC) and enterohaemorrhagic (EHEC) Escherichia coli isolated from cattle were studied by DNA colony hybridization to subtype their intimin-encoding (eae) gene with probes derived from the variable parts of the eae alpha gene of the human EPEC strain E2348/69, the eae gamma gene of the human O157:H7 EHEC strain ATCC43888, and the eae beta gene of the bovine O26:H- EHEC strain 193, whose eae gene was first cloned and sequenced during this work. The EPEC and EHEC had been isolated from diarrhoeic calves (143 EPEC and 48 EHEC) and from healthy animals at the slaughterhouse (1…
