Escherichia coli H-Genotyping PCR: a Complete and Practical Platform for Molecular H Typing.

In , more than 180 O groups and 53 H types have been recognized. The O:H serotyping of strains is an effective method for identifying strains with pathogenic potential and classifying them into clonal groups. In particular, the serotyping of Shiga toxin-producing (STEC) strains provides valuable information to evaluate the routes, sources, and prevalence of agents in outbreak investigations and surveillance.
