TABLE 3.
Distribution of phylogenetic groups among 197 E. coli isolates recovered from patients with urosepsis and from the feces of healthy individuals
| Phylogenetic group | No. (%) of E. coli isolates |
Pa | |
|---|---|---|---|
| Fecal (n = 51) | Urosepsis (n = 146) | ||
| A | 19 (37) | 27 (18) | (0.011) |
| B1 | 12 (24) | 7 (5) | (<0.001) |
| B2 | 12 (24) | 79 (54) | <0.001 |
| D | 8 (16) | 33 (23) | |

P values (by Fisher's exact test) are shown where P is <0.05. P values given in parentheses indicate negative associations between the prevalence of the urosepsis strains and the particular phylogroup.
