Identification of Human-Pathogenic Strains of Shiga Toxin-Producing <i>Escherichia coli</i> from Food by a Combination of Serotyping and Molecular Typing of Shiga Toxin Genes

Abstract excerpt

We examined 219 Shiga toxin-producing Escherichia coli (STEC) strains from meat, milk, and cheese samples collected in Germany between 2005 and 2006. All strains were investigated for their serotypes and for genetic variants of Shiga toxins 1 and 2 (Stx1 and Stx2). stx(1) or variant genes were detected in 88 (40.2%) strains and stx(2) and variants in 177 (80.8%) strains. Typing of stx genes was performed by...
