title: Type IV longus pilus of enterotoxigenic Escherichia coli: occurrence and association with toxin types and colonization factors among strains isolated in Argentina.
abstract: The longus type IV pilus structural gene (lngA) was sought among 217 clinical enterotoxigenic Escherichia coli (ETEC) strains isolated in Argentina. lngA was present in 20.7% of the isolates and was highly associated with ETEC producing heat-stable toxin and the most common colonization factors. The prevalence of longus among ETEC strains in Argentina was comparable to that of colonization factor antigen I (CFA/I), CFA/II, and CFA/IV in other regions of the world.
