UTI strains more often than fecal strains carried all tested virulence genes, i.e., fimA (74 vs. 73%, p = 0.92), papC (72 vs. 29%, p < 0.0001), sfaD/E (45 vs. 27%, p < 0.0001), hlyA (45 vs. 22%, p < 0.0001), iutA (56 vs. 28%, p < 0.0001), neuB (31 vs. 22%, p = 0.03), and kfiC (15 vs. 7%, p = 0.009). This evidence concerns the gene PCDH8 and bacterial urinary tract infection.
