The Bacteroides fragilis toxin (bft) Gene: Its Role in Virulence, Regulation, and Disease

Eurasian Journal of Applied Biotechnology
Bacteroides fragilis can be divided into two different groups of strains: an enterotoxigenic strain (ETBF) that has a pathogenicity island and the Bacteroides fragilis toxin gene (bft) and a non-toxigenic strain (NTBF) that does not have a pathogenicity island and the bft gene.

Gut microbiota and diet in colorectal cancer: Converging determinants of carcinogenesis

Gut Microbes
Diet and the gut microbiome are major, interdependent determinants of colorectal cancer (CRC) risk. This review discusses current evidence on how dietary patterns reshape microbial ecology, modulate microbial virulence, and alter host metabolic ...

[Toxins of Bacteroides fragilis and Bacteroides thetaiotaomicron rods as stimulators of adhesion molecule expression on the surface of vascular endothelial cells].

Medycyna doswiadczalna i mikrobiologia, 2000
Lipopolysaccharides from four Bacteroides fragilis strains: one nonenterotoxigenic (NTBF) and three enterotoxigenic (ETBF), and from three B. thetaiotaomicron strains were extracted by hot phenol-water method and purified. B. fragilis enterotoxin was prepared according to the procedure of van Tassell et al. (1992).
