To evaluate the presence of Escherichia coli O157, cloacal swabs were collected from 60 adult frogs kept as pets and analyzed by culture methods and multiplex polymerase chain reaction for stx1, stx2, and E. coli attaching and effacing (eae) and hly genes. The pathogen was isolated from two samples and both carried stx2 gene. This is believed to be the first report of natural E. coli O157 infection in living frogs.
