Abstract:
... Enterohemorrhagic Escherichia coli (EHEC) is a subtype of pathogenic E. coli that causes diarrhea or hemorrhagic colitis in humans, which can progresses to hemolytic uremic syndrome (HUS), a leading cause of acute renal failure in children, and morbidity and mortality in adults. Stool samples (n = 273) of patients (1 day-40 years old) suffered from bloody diarrhea and abdominal cramps, were examin ...

Abstract:
... Quality and microbial safety of milk is demanding day by day as it is considered as a host for pathogenic and spoilage microorganisms. In this study, isolation and molecular characterization of shigatoxigenic O157 and non-O157 Escherichia coli in raw milk marketed in Chittagong, Bangladesh were done on 186 raw milk samples in Bangladesh. MacConkey agar was initially used to screen for the presence ...

Shiga-like toxins; enterohemorrhagic Escherichia coli; food safety; foods; genes; intimin; karsts; quantitative polymerase chain reaction; springs (water); virulence; virulent strains; Switzerland
Abstract:
... 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 ...

Abstract:
... A micro-array has been developed, based on the GeneDisc® array, for the genetic identification of 12 O-types and 7 H-types of Shiga toxin-producing Escherichia coli (STEC) including the most clinically relevant enterohemorrhagic E. coli (EHEC) serotypes. The genes selected for determination of the O antigens (rfbE O₁₅₇, wzx O₂₆, wzx O₁₀₃, wbd1 O₁₁₁, ihp1 O₁₄₅, wzx O₁₂₁, wzy O₁₁₃, wzy O₉₁, wzx O₁₀₄ ...

Abstract:
... Detection and distribution of eae gene in forty-four attaching and effacing Escherichia coli (AEEC) strains of animal origin were investigated. Association of distinct intimin alleles with phylogenetic background were assessed among strains in comparison with different serogroups. Phylogenetic analysis showed that 31 EHEC/eae+ STEC strains belong to groups A, B1 and E, 13 EPEC strains segregated i ...
