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

Infection 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 ...

The Role of the Bacteroides spp. in Bacteraemia

Postępy Mikrobiologii, 2022
Anaerobic bacteraemia is not frequent (1.2–13.7%), but is associated with a high mortality rate of 16–27%. Anaerobic infections including bacteraemia nearly always arise from contamination by endogenous bacteria into contiguous or other sites like ...

CRISPR-Cas Systems in Bacteroides fragilis, an Important Pathobiont in the Human Gut Microbiome

Frontiers in Microbiology, 2017
Background: While CRISPR-Cas systems have been identified in bacteria from a wide variety of ecological niches, there are no studies to describe CRISPR-Cas elements in Bacteroides species, the most prevalent anaerobic bacteria in the lower intestinal ...

A review of the role of enterotoxigenic Bacteroides fragilis in the development of colorectal cancer

Basic & Clinical Cancer Research
Enterotoxigenic Bacteroides fragilis (ETBF) plays a significant role in the development and progression of colorectal cancer (CRC) through the production of Bacteroides fragilis toxin (BFT). This toxin activates Wnt, NF-κB, and STAT3 signaling pathways,

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

An intracellular structure in Bacteroides fragilis [PDF]

Journal of Medical Microbiology, 1981
An unusual intracellular circular or oval structure was discovered during a morphological study of Bacteroides fragilis by electronmicroscopy. The structure is complex, composed of multiple concentric layers surrounding a central region. The dimensions and profile are consistent in all the sections observed.
