Molecular serotyping of Escherichia coli O111:H8

Accurate Escherichia coli serotyping is critical for pathogen diagnosis and surveillance of non-O157 Shiga-toxigenic strains, however few laboratories have this capacity. The molecular serotyping protocol described in this paper targets the somatic and flagellar antigens of E. coli O111:H8 used in traditional serotyping, and can be performed routinely in the laboratory.
