O-antigen biosynthesis gene clusters of Escherichia albertii: their diversity and similarity to Escherichia coli gene clusters and the development of an O-genotyping method.

ABSTRACT: Escherichia albertii is a recently recognized human enteropathogen that is closely related to Escherichia coli. In many Gram-negative bacteria, including E. coli, O-antigen variation has long been used for the serotyping of strains. In E. albertii, while eight O-serotypes unique to this species have been identified, some strains have been shown to exhibit genetic or serological similarity to known E. coli/Shigella O-serotypes. However, the diversity of O-serotypes and O-antigen biosynthesis gene clusters (O-AGCs) of E. albertii remains to be systematically investigated. Here, we analysed the O-AGCs of 65 E. albertii strains and identified 40 E. albertii O-genotypes (EAOgs) (named EAOg1-EAOg40). Analyses of the 40 EAOgs revealed
