Good Gone Bad: One Toxin Away From Disease for Bacteroides fragilis

Journal of Molecular Biology, 2020
The human gut is colonized by hundreds of trillions of microorganisms whose acquisition begins during early infancy. Species from the Bacteroides genus are ubiquitous commensals, comprising about thirty percent of the human gut microbiota. Bacteroides fragilis is one of the least abundant Bacteroides species, yet is the most common anaerobe isolated ...

Characterization of enterotoxigenic Bacteroides fragilis by a toxin-specific enzyme-linked immunosorbent assay

Clinical Diagnostic Laboratory Immunology, 1994
Within the past decade, certain strains of Bacteroides fragilis have been associated with diarrhea in humans and cytotoxic activity on certain colon carcinoma cell lines. An enzyme-linked immunosorbent assay (ELISA) for detecting the enterotoxin of B.

Detection of the Bacteroides fragilis toxin gene in sheep with and without small intestinal adenocarcinoma

New Zealand Veterinary Journal, 2019
Aims: To determine if presence of the Bacteroides fragilis toxin (bft) gene, a molecular marker of colonic carriage of entertoxigenic Bacteroides fragilis (ETBF) in humans, was associated with a finding of small intestinal adenocarcinomas (SIA) in sheep in New Zealand.

Enterotoxin-producing Bacteroides fragilis (ETBF) Strains in Stool Samples Submitted for Testing ofClostridium difficile and its Toxins

Anaerobe, 1999
Abstract Fifty faecal samples of patients suspected of having diarrhoea associated with Clostridium difficile were studied. Toxins of C. difficile were tested in vivo directly from the faecal sample using Toxin Detection Kits (Oxoid) to detect toxin A and primers for detection genes of Toxin A and B in a PCR test.

Dioctahedral smectite neutralization activity of Clostridium difficile and Bacteroides fragilis toxins in vitro.

Acta microbiologica Polonica, 1998
The neutralization activity of dioctahedral smectite for ten toxigenic Clostridium difficile and eight enterotoxigenic Bacteroides fragilis strains was studied using McCoy and HT 29/C1 cell lines, respectively. Minimalization of the cytopathic effect of C.

Discovery and Characterization of an Antimicrobial Toxin of the Gut Symbiont Bacteroides fragilis

2019
The gut microbiota represents one of most densely populated ecosystems on earth. The trillions of bacteria that populate the gastrointestinal tract carry out essential tasks for the host, such as harvesting energy from food, synthesizing micronutrients, and participating in the development of the immune system.
