Bacteroides fragilis produces polysaccharide A (PSA), known for its immunomodulatory properties, and activates the T cells. It also activates TLR-2 in PSA-dependent manner, upgrading regulatory T cells for immune tolerance and maintenance of intestinal homeostasis [47,48]. B. fragilis has also ...
Bacteroides fragilis is symbiotic with the host but if it reaches sterile extraluminal sites can be responsible for tissue infection, bacteremia, abscess formation in the peritoneal cavity, brain, liver, pelvis, or lungs.5,6 The control of pathogens by the inflammatory process is required to main...
Pathogenesis of Bacteroides fragilis The pathogen contains an antiphagocytic capsule, which adheres to the peritoneal surface. This results in abscess formation. Surgery and trauma accentuate the problem since they disrupt the abscess, allowing for the endogenous spread of the organism into the bloodstre...

A guinea-pig model for induction of otitis-media by anaerobic 7 bacteria is described. Bacteroides fragilis (4–8x10 colony forming units) injected via the tympanic membrane was capable of inducing intense inflammation with persisting sequelae and surviv
(Keenan et al., 2016).Bacteroides fragilisis the most frequently anaerobic pathogen isolates from clinical specimens including extra-intestinal infections such as diabeticfootinfection,brain, lung, abdominal and pelvic abscesses, surgical site infections and sepsis (Akhi et al., 2015a;Akhi et al....
fragilisΔPSA strain was severely attenuated in its ability to induce abscesses in vivo. (Coyne et al., 2001) PSA (+) PSA synthesis locus with 8185 bp deletion The B. fragilisΔPSA strain is not capable of correcting systemic T cell deficiencies and H1/TH2 imbalances, as well as guiding...
EnterotoxigenicB. fragilisis the most common anaerobic isolate identified in clinical specimens which causes different types of infections related to intestinal and genitourinary tracts25. This toxigenic strain has reported to cause severe abscess formation and bacteremia as it is regarded as the only so...
