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 186 isolates carried a vt(2) gene. Moreover, the vt(2) subtype, which is associated with serious disease, was present in 42% of our VTEC collection. The other vt subtypes detected were vt(1), vt(1d), vt(2vha), vt(2vhb), vt(2O118), vt(2d) (mucus activatable), and vt(2g). A total… CONTINUE READING
