Cattle can be a reservoir of sorbitol-fermenting Shiga toxin-producing Escherichia coli O157 : H- strains and a source of human diseases

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.
