Prevalence and association of the longus pilus structural gene (lngA) with colonization factor antigens, enterotoxin types, and serotypes of enterotoxigenic Escherichia coli

Abstract excerpt

Human enterotoxigenic Escherichia coli (ETEC) produces a plasmid-encoded type IV pilus termed longus (for long pilus). Regardless of the geographic origins of ETEC strains, the longus structural gene lngA was found to have the highest level of association with ETEC producing colonization factor antigen (CFA) CFA/II, followed by ETEC producing CFA/I and CFA/IV. ETEC bearing the less prevalent CFA/III and putative...
