Prevalence of afaC+, pks+ E coli in patients with CD, colitis and colon cancer compared with controls (using total number of patients as the denominator)†

	Total no of patients	afaC+, pks+	p Value*
CD	14	4	NS
CRC	21	11	0.0015
UC	21	8	0.0222
Controls	24	2

*p Values obtained using Fisher's exact test (2P component).

†Presence or absence of afaC and pks is based on PCR assay.

afaC, gene encoding afimbrial adhesin outer membrane usher protein; CRC, colorectal cancer; pks, polyketide synthase gene complex; UC, ulcerative colitis.
