Survival of Escherichia coli O157: H7 in drinking water associated with a waterborne disease outbreak of hemorrhagic colitis

Abstract

Survival characteristics were similar for two strains of Escherichia coli O157: H7 and a typical indicator strain of E. coli in a portable ground water source. Die-off was more rapid at 20°C than at 5°C. There was no significant difference among the rates of survival for the strains examined.
