Serotypes and virulence gene profiles of shiga toxin -producing Escheichia coli strains isolated from feces of pasture-fed and lot-fed sheep

The shiga toxin -producing Escherichia coli (STEC) strains contain genes for enterohemolysin (ehxA) and intimin, identified as complex STEC (cSTEC) and are generally recuperated from the feces of human beings with hemolytic uremic and hemorrhagic colitis condition. To identify whether the modifications in the diet affects the excretion pattern of cSTEC, the virulence gene profiles and serotypes of cSTEC were located from pasture-fed sheep.
