A total of 108 Escherichia coli strains characterized as enteropathogenic (EPEC) by serotyping and the presence of EPEC adherence factor (EAF) sequences were examined for cytotoxin production by cell line assays and colony ...

Raw beef samples (n=105) were examined for diarrheagenic Escherichia coli (DEC) using standard methods. The isolates obtained (n=1,066) were screened for Shiga-like toxins (SLT-I and SLT-II), cytolethal distending toxin ...

Shiga toxins (Stx) are the main virulence factors in enterohemorrhagic Escherichia coli (EHEC) infections, causing diarrhea and hemolytic uremic syndrome (HUS). The genes encoding for Shiga toxin-2 (Stx2) are located in a ...

Production of Shiga toxin (Stx) in Escherichia coli strains belonging to serogroups O26, O111, and O157 was evaluated in the rabbit ileal loop assay and results were compared to those using tissue culture assays and DNA ...

Shiga toxin (Stx2) producing Escherichia coli infections during early gestation may impair placentation through a Stx2 damage of extravillous trophoblast (EVT) cells. We have previously demonstrated that Stx2 injected in ...
