Prevalence of the set-1B and astA genes encoding enterotoxins in uropathogenic Escherichia coli clinical isolates.
One hundred seventy human uropathogenic Escherichia coli (UPEC) clinical isolates were compared with 35 E. coli strains isolated from feces of a control group to determine the presence of the set1, sen and astA genes encoding the ShET-1, ShET-2, and EAST toxins, respectively. Overall, 27 (16%), 8 (8%) and 0 UPEC isolates presented the set1B, the astA, and the sen genes, respectively. This is the first time the set gene has been found in UPEC clinical isolates.
