Extraction and Evaluation of Outer Membrane Vesicles from Two Important Gut Microbiota Members, Bacteroides fragilis and Bacteroides thetaiotaomicron

open access: yesCell Journal, 2020
Objective: The gastrointestinal tract (GI) is colonized by a complex microbial community of gut microbiota. Bacteroides spp. have significant roles in gut microbiota and they host interactions by various mechanisms, including outer membrane vesicle ...

Genome Characterization of a Novel Wastewater Bacteroides fragilis Bacteriophage (vB_BfrS_23) and its Host GB124

open access: yesFrontiers in Microbiology, 2020
Bacteroides spp. are part of the human intestinal microbiota but can under some circumstances become clinical pathogens. Phages are a potentially valuable therapeutic treatment option for many pathogens, but phage therapy for pathogenic Bacteroides spp ...

Bacteroides fragilis Enterotoxin Gene Sequences in Patients with Inflammatory Bowel Disease

open access: yesEmerging Infectious Diseases, 2000
We identified enterotoxigenic Bacteroides fragilis in stool specimens of patients with inflammatory bowel disease and other gastrointestinal disorders. The organism was detected in 11 (13.2%) of 83 patients with inflammatory bowel disease. Of 57 patients

The enterotoxin of Bacteroides fragilis is a metalloprotease [PDF]

open access: yesInfection and Immunity, 1995
During the past decade, strains of Bacteroides fragilis that produce an enterotoxin have been implicated in diarrheal disease in animals and humans. The extracellular enterotoxin has been purified and characterized as a single polypeptide (M(r), approximately 20,000). Single specific primer-PCR was used to clone a portion of the B. fragilis enterotoxin

Virulence markers and antimicrobial susceptibility of bacteria of the Bacteroides fragilis group isolated from stool of children with diarrhea in São Paulo, Brazil

open access: yesMemorias do Instituto Oswaldo Cruz, 2004
Bacteroides fragilis has been isolated from several human and non-human monomicrobial and mixed infections. In this study, some virulence markers and the antimicrobial susceptibility of bacteria of the B.

Adherence of Bacteroides fragilis in vivo [PDF]

open access: yesInfection and Immunity, 1978
The ability of the encapsulated species Bacteroides fragilis to adhere to rat peritoneal mesothelium was compared to the adherence of unecapsulated strains of Bacteroides (B. distasonis, B. vulgatus, B. thetaiotaomicron, B. ovatus, and B. "other"). Adherence was assayed by attaching plexiglas plates containing 8-mm holes to the peritoneal mesothelium ...

Antimicrobial resistance profile and Nim gene detection among Bacteroides fragilis group isolates in a university hospital in South India

open access: yesJournal of Global Infectious Diseases, 2019
Introduction: Members of Bacteroides fragilis group are the most frequently isolated anaerobic pathogens in the clinical laboratory from diverse infection sites. The objective of this study was to characterize B.

Outer membrane vesicles secreted by Bacteroides fragilis inhibit CFTR chloride secretion by human colon organoids

open access: yesInfection and Immunity
The goals of this study were to develop a model to study host-pathogen interactions in primary human colon organoids and to test the hypothesis that Bacteroides fragilis toxin (BFT-2) secreted in outer membrane vesicles (OMVs) modulates mucosal immunity ...

A study on Nim expression in Bacteroides fragilis [PDF]

open access: yesMicrobiology, 2014
Members of the genus Bacteroides, mainly Bacteroides fragilis, can cause severe disease in man, especially after intestinal perforation in the course of abdominal surgery. Treatment is based on a small number of antibiotics, including metronidazole, which has proved to be highly reliable throughout the last 40 to 50 years.
