Colonization with enterotoxigenic Bacteroides fragilis is associated with early-stage colorectal neoplasia

Abstract excerpt

BACKGROUND: Enterotoxigenic Bacteroides fragilis (ETBF) is a toxin-producing bacteria thought to possibly promote colorectal carcinogenesis by modulating the mucosal immune response and inducing epithelial cell changes. Here, we aim to examine the association of colonic mucosal colonization with ETBF and the presence of a range of lesions on the colonic neoplastic spectrum. METHODS: Mucosal tissue from up to four...
