Presence of afaC+, pks+ E coli in patients with CD, colitis and colon cancer compared with controls (using total number of E coli as the denominator)†
| afaC+, pks+ | afaC−, pks− | p Value* | |
|---|---|---|---|
| CD | 13 | 58 | NS |
| CRC | 35 | 85 | 0.0119 |
| UC | 17 | 34 | 0.0082 |
| Controls | 3 | 36 |
*p Values obtained using χ2 test (Yates-corrected).
†Presence or absence of afaC and pks is based on PCR assay.
afaC, gene encoding afimbrial adhesin outer membrane usher protein; CD, Crohn's disease; CRC, colorectal cancer; pks, polyketide synthase gene complex; UC, ulcerative colitis.
