Summary of PCR-ribotypes detected in Escherichia coli cultured from several Norovirus patients.

Abbreviations: UG, Norovirus patient with an undisrupted microbiota; DG, Norovirus patient with a disrupted microbiota.Individuals with Norovirus infection contained a dominant type of E. coli (80–100% of isolates examined were a single type). Additionally, some PCR ribotypes were shared amongst multiple Norovirus patients, but most types were unique to each patient and each group. Ribotypes were assigned based upon allele combinations seen in Table S5.
