Colonization factor antigens (CFAs) of enterotoxigenic Escherichia coli (ETEC) have been classified into several groups based on their distinct antigenicity. We describe here a PCR-based method to detect common CFAs of ETEC, which were characterized using conventional serology. This PCR assay is simple and sensitive for the detection of expressed CFA genes.
