Genetic characterization of the wb* gene in a series ofEscherichia coli and Klebsiella strains possessing the mannose homopolymer as the O-specific polysaccharide was carried out. The partial nucleotide sequences and PCR-restriction fragment length polymorphism analysis suggested that E. coli serotype O9a, a subtype of E. coli O9, might have been generated by the insertion of theKlebsiella O3 wb* gene into a certainE. coli strain.
