- ... Pathogenicity of enterohemorrhagic Escherichia coli (EHEC) strains depends on various virulence factors, like adhesins (including intimin), flagella, type I fimbriae, curli fibers, hemolysins, and agents required for biofilm formation. However, the pathogenicity is highly enhanced by production of Shiga toxins which are encoded by stx genes located in genomes of Shiga toxin-converting (Stx) propha ...

- ... Within 2 months, two water sources in a karst area in Switzerland were sampled 9 times each, and analyzed by real-time PCR for 6 EHEC O-types, Shiga-like-toxin (stx1 and stx2) and intimin (eae) genes. With the exception of O111, 5 O-types were recorded regularly and at high frequencies (O26: 33.3 %; O157: 33.3 %; O104: 66.6 %; O103: 72.2 %; O145: 94.4 %). Genes for Shiga-like-toxins and intimin we ...
