Presence of Activatable Shiga Toxin Genotype ( stx 2d ) in Shiga Toxigenic Escherichia coli from Livestock Sources

1 Aug 2003

Abstract excerpt

Stx2d is a recently described Shiga toxin whose cytotoxicity is activated 10- to 1000-fold by the elastase present in mouse or human intestinal mucus. We examined Shiga toxigenic Escherichia coli (STEC) strains isolated from food and livestock sources for the presence of activatable stx(2d). The stx(2) operons of STEC were first analyzed by PCR-restriction fragment length polymorphism (RFLP) analysis and...
