Abstract

Numerous studies support a role for the intestinal microbiota in colorectal tumorigenesis. Although colon cancer has not yet been epidemiologically linked to specific bacterial species, recent results suggest that certain toxigenic commensal bacteria may be oncogenic Strains of Escherichia coli, a ubiquitous member of the colonic flora, synthesize a genotoxin called colibactin. These bacteria induce DNA double-strand breaks in intestinal cells and trigger chromosomal instability, gene mutations and cell transformation. Thus, long-term colonization of the colon by rogue commensal bacteria capable of causing chronic DNA damage could contribute to the development of sporadic colorectal cancer.

Abstract

Virulence factors and phenotypes of 61 strains CNF1+ were investigated. Eighty-nine percent of the strains produced an aerobactin and were resistant to the bactericidal activity of sheep serum, both of which are properties of septicemic strains of E coli. None of the strains reacted either with DNA probes corresponding to the enterotoxins STaP, STb, LT-I and LT-IIa, or to the verotoxins VT-I and VT-II. None produced the adhesins K99, Att25 (FY or F17) and Att111. The great majority (93.4%) of the CNF1+E coli possessed both properties. These properties allow CNF1+ to be distinguished from CNF-E coli.
