Prevalence of enterotoxigenic Escherichia coli strains harboring the longus pilus gene in Brazil.
The longus type IV pilus gene (lngA) was highly prevalent (32.8%) among Brazilian enterotoxigenic Escherichia coli strains producing both heat-labile and heat-stable enterotoxins and bearing the CFA/I, CS1CS3, or CS6 antigen. Furthermore, lngA was more often found in strains isolated from children with diarrhea than in strains isolated from children without diarrhea.
