Abstract
Escherichia coli 0157:H7 has been associated with a number of waterborne outbreaks, but it has never been recovered from an implicated environment. This paper reports on an August 1999 outbreak of E. coli 0157:H7 associated with swimming in Battle Ground Lake in Clark County, Washington. E. coli 0157:H7 was isolated from duck feces, as well as from two water samples. The authors used pulsed-field gel electrophoresis to compare these isolates with patent isolates for genetic homology. All the isolates yielded the same restriction fragment patterns. In addition, using polymerase chain reaction, the authors found patient isolates and environmental isolates to have the same virulence factors (Stx, eaeA, and hly). [ABSTRACT FROM AUTHOR]
