Gut Bacteroides fragilis in health and diseases: an updated review

Journal of Future Foods
The gut microbiota plays an essential role in maintaining host health, with the genus Bacteroides being a prominent member of this microbial community. Among the Bacteroides spp., Bacteroides fragilis is a commensal, obligate anaerobe commonly found in ...

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 ...

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 ...

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,

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.

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.

Anaerobic utilization of Fe(III)‐xenosiderophores among Bacteroides species and the distinct assimilation of Fe(III)‐ferrichrome by Bacteroides fragilis within the genus

MicrobiologyOpen, 2017
In this study, we show that Bacteroides species utilize Fe(III)‐xenosiderophores as the only source of exogenous iron to support growth under iron‐limiting conditions in vitro anaerobically.

Nanocellulose Alleviates Intrahepatic Cholestasis of Pregnancy via Gut Microbiota‐Mediated Bile Acid Homeostasis

Advanced Science, EarlyView.
Nanocellulose, derived from microcrystalline cellulose (MCC) through sulfuric acid hydrolysis or mechanical grinding to produce CNC or CNF, was tested in a rat ICP model. Particularly, CNF improved gut microbiota composition, reduced secondary bile acid metabolism, and restored bile acid homeostasis through modulation of the gut–liver axis.

Multi‐Targeting Carnosic Acid Kills Drug‐Resistant Helicobacter pylori With Narrow‐Spectrum Activity

Advanced Science, EarlyView.
Carnosic acid selectively eradicates drug‐resistant Helicobacter pylori through a multi‐targeted mechanism involving urease inhibition, membrane disruption, and biofilm eradication. It exhibits no detectable resistance, potent in vivo efficacy, and minimal impact on gut microbiota, positioning it as a promising narrow‐spectrum lead compound against ...
