Abstract

Shiga Toxin - genetics Animals Escherichia coli - isolation & purification Escherichia coli - pathogenicity Virulence Animal Husbandry Female Seasons Cattle - microbiology Escherichia coli - classification
Shiga-toxigenic Escherichia coli (STEC) strains were isolated from 7.4% of 1,440 fecal and farm environmental samples. Shiga toxin gene and STEC prevalences were significantly associated with animal production type and season. A range of serogroups were identified. Nine percent of isolates possessed all three principal virulence markers: stx(2), eae, and ehx.
