Verotoxin-producing Escherichia coli (VTEC) are important pathogens that can cause severe human disease, including haemorrhagic colitis and haemolytic-uraemic syndrome. A new variant of verotoxin, vt2g, has recently been ...

In this study, we determined vt subtypes and evaluated verotoxicity in basal as well as induced conditions of verotoxin-producing Escherichia coli (VTEC) strains isolated from cattle and meat products. Most (87%) of the ...

Verotoxin-producing E. coli (VTEC) O157:H7 is the dominant serotype isolated from patients with HUS and, Argentina has the highest rate of HUS in the world. Molecular typing had allowed to identify subpopulations related ...

We investigated the presence of the gene of subtilase cytotoxin (SubAB), described in certain highly virulent verocytotoxigenic E. coli strains, in isolates from Argentina and its relation with other virulence factors. The ...

Five verotoxin-producing non-O157:H7 Escherichia coli (VTEC) isolates (serotypes O26:H11, O91:H21, O111:H-, O145:H-, O174:H21) from hamburger and cattle, one O157:H7 clinical strain (human) and one O157:H7 strain isolated ...

Verotoxin-producing Escherichia coli O157:H7 is the dominant serotype isolated from patients with hemolytic-uremic syndrome (HUS) and, Argentina has the highest rate of HUS in the world. However, not all O157:H7 isolates ...
