Stx2 Subtyping of Shiga Toxin-Producing <i>Escherichia coli</i> Isolated from Cattle in France: Detection of a New Stx2 Subtype and Correlation with Additional Virulence Factors

Abstract excerpt

At least 11 Stx2 variants produced by Shiga toxin-producing Escherichia coli (STEC) isolated from patients and animals have been described. The Stx2 subtyping of STEC isolated from healthy cows positive for stx(2) (n = 104) or stx(2) and stx(1) (n = 63) was investigated. Stx2vh-b, Stx2 (renamed Stx2-EDL933), and Stx2vh-a were the subtypes mostly detected among the bovine isolates (39.5, 39, and 25.5%,...
