The Bacteroides fragilis pathogenicity island links virulence and strain competition.
Casterline BW, et al. Gut Microbes 2017. PMID 28632016 Free PMC article.
We show here that a second enterotoxigenic strain is competent to colonize, dependent on the Bacteroides fragilis pathogenicity island (BFPAI). Additional data showing complex environmental regulation of the Bacteroides fragilis toxin (BFT) suggest that virulence factors may be adapted to modify the colonic niche to provide a strain-specific colonization advantage. ...

Bacteroides: the good, the bad, and the nitty-gritty.
Wexler HM. Clin Microbiol Rev 2007 - Review. PMID 17934076 Free PMC article.
Bacteroides species are significant clinical pathogens and are found in most anaerobic infections, with an associated mortality of more than 19%. ...Species of the genus Bacteroides have the most antibiotic resistance mechanisms and the highest resistance rates of all anaerobic pathogens. ...

Association Between Bacteremia From Specific Microbes and Subsequent Diagnosis of Colorectal Cancer
Kwong TNY, et al. Gastroenterology 2018. PMID 29729257
BACKGROUND & AIMS: Colorectal cancer (CRC) development has been associated with increased proportions of Bacteroides fragilis and certain Streptococcus, Fusobacterium, and Peptostreptococcus species in the intestinal microbiota. ...We collected data on intestinal microbes previously associated with CRC (genera Bacteroides, Clostridium, Filifactor, Fusobacterium, Gemella, Granulicatella, Parvimonas, Peptostreptococcus, Prevotella, Solobacterium, and Streptococcus). ...

Gut Microbiota Linked to Sexual Preference and HIV Infection
Noguera-Julian M, et al. EBioMedicine 2016. PMID 27077120 Free PMC article.
Initial cross-sectional studies provided contradictory associations between microbial richness and HIV serostatus and suggested shifts from Bacteroides to Prevotella predominance following HIV-1 infection, which have not been found in animal models or in studies matched for HIV-1 transmission groups. In two independent cohorts of HIV-1-infected subjects and HIV-1-negative controls in Barcelona (n = 156) and Stockholm (n = 84), men who have sex with men (MSM) predominantly belonged to the Prevotella-rich enterotype whereas most non-MSM subjects were enriched in Bacteroides, independently of HIV-1 status, and with only a limited contribution of diet effects. ...

Pathogenicity of the Bacteroides fragilis group.
Brook I. Ann Clin Lab Sci 1989 - Review. PMID 2679351
Bacteroides fragilis accounts for 63 percent of all the group isolates, Bacteroides thetaiotaomicron for 14 percent, Bacteroides vulgatus and Bacteroides ovatus for seven percent each, Bacteroides distasonis for six percent and Bacteroides uniformis for two percent. ...Antimicrobial therapy directed only at the eradication of the aerobic bacteria did not prevent encapsulation, or reduce the number of Bacteroides species. ...

Screening for enterotoxigenic Bacteroides fragilis in stool samples.
Keenan JI, et al. Anaerobe 2016. PMID 27166180
Bacteroides fragilis is a commensal bacterium found in the gut of most humans, however enterotoxigenic B. fragilis strains (ETBF) have been associated with diarrhoea and colorectal cancer (CRC). The purpose of this study was to establish a method of screening for the Bacteroides fragilis toxin (bft) gene in stool samples, as a means of determining if carriage of ETBF is detected more often in CRC patients than in age-matched healthy controls. ...

Pathogenicity of Bacteroides fragilis group in rat intra-abdominal abscesses.
Jotwani R, et al. Microbiol Immunol 1992. PMID 1479960 Free article.
Studies with the electron microscope showed presence of capsular polysaccharide only in Bacteroides fragilis and Bacteroides thetaiotaomicron. It was doubtful in Bacteroides distasonis and absent in Bacteroides ovatus and Bacteroides vulgatus, suggesting that virulence factor beside the capsular polysaccharide may be playing a role. ...

An immunomodulatory molecule of symbiotic bacteria directs maturation of the host immune system
Mazmanian SK, et al. Cell 2005. PMID 16009137 Free article.
Here we show that, during colonization of animals with the ubiquitous gut microorganism Bacteroides fragilis, a bacterial polysaccharide (PSA) directs the cellular and physical maturation of the developing immune system. ...
