Cephalosporinase Activity in Bacteroides fragilis [PDF]
Antimicrobial Agents and Chemotherapy, 1973 Cephalosporinase activity was demonstrated in all of 10 strains of Bacteroides fragilis investigated. Low rates of hydrolysis of cephalosporins (0.25 to 3.5 μmol of cephaloridine per h per 10 9 cells) were found, but no activity against penicillin substrates was detected.

Immune Evasion of Helicobacter pylori and Extra‐Gastric Cancer Risk
Journal of Gastroenterology and Hepatology, EarlyView.ABSTRACT Helicobacter pylori (H. pylori) is a group 1 gastric carcinogen that plays a significant role in extra‐gastric digestive system cancers. H. pylori disrupts host cell homeostasis through expression of virulence factors leading to immune evasion as well as persistent gastric mucosal colonization. H. pylori infection has been shown to play a role

Evidence of Extensive DNA Transfer between Bacteroidales Species within the Human Gut [PDF]
, 2014 The genome sequences of intestinal Bacteroidales strains reveal evidence of extensive horizontal gene transfer. In vitro studies of Bacteroides and other bacteria have addressed mechanisms of conjugative transfer and some phenotypic outcomes of these DNA

Emphysematous pyelonephritis caused by Bacteroides fragilis [PDF]
Nephrology Dialysis Transplantation, 2005 A 50-year-old male presented with fever and anorexia of 2 days’ duration and a 3-week history of abdominal fullness. Two years earlier, he had left-sided acute pyelonephritis, incomplete duplicated ureters and a ureteral stone. The stone was removed. He also had hypertension, gout, and chronic renal failure with a serum creatinine 3.1mg/dl. Examination

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis
Journal of Periodontal Research, EarlyView.Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Early intestinal
BMC Pulmonary Medicine, 2008 Background The 'hygiene hypothesis' suggests that early exposure to microbes can be protective against atopic disease. The intestinal microbial flora could operate as an important postnatal regulator of the Th1/Th2 balance.
