a
The UTI collection includes 30 urinary tract isolates from a previously described collection (19, 23) plus E. coli CFT073. The PATH collection strains are listed in Table 2.
b
The incidence of each genetic locus, determined by duplex PCR as described in Materials and Methods and footnote a to Table 4, is reported as percent occurrence for the collections and presence (+) or absence (−) for individual isolates. Loci putP and proV were detected in all strains.
