Abstract

Using the immunomagnetic separation procedure, we isolated sorbitol-fermenting (SF) Shiga toxin-producing Escherichia coli (STEC) O157:H strains from two patients, one with hemolytic-uremic syndrome and the other with diarrhea, and from a dairy cow epidemiologically associated with the patients. The phenotypic and genotypic characteristics of all isolates were identical or closely related. Moreover, the bovine isolate showed a clonal relatedness to SF STEC O157:H strains isolated from patients in Germany and the Czech Republic from 1988 to 1998. This is the first evidence that cattle can be a reservoir of SF STEC O157:H and a source of human diseases.
