Roving methyltransferases generate a mosaic epigenetic landscape and influence evolution in Bacteroides fragilis group [PDF]

Nature Communications, 2023
Three types of DNA methyl modifications have been detected in bacterial genomes, and mechanistic studies have demonstrated roles for DNA methylation in physiological functions ranging from phage defense to transcriptional control of virulence and host ...

Surveillance of Antimicrobial Susceptibility of Anaerobe Clinical Isolates in Southeast Austria: Bacteroides fragilis Group Is on the Fast Track to Resistance [PDF]

Antibiotics, 2021
Anaerobic bacteria play an important role in human infections. Bacteroides spp. are some of the 15 most common pathogens causing nosocomial infections. We present antimicrobial susceptibility testing (AST) results of 114 Gram-positive anaerobic isolates ...

Carbapenem resistance in enterotoxigenic Bacteroides fragilis isolated from colonoscopy candidates [PDF]

AMB Express
The present study aimed to determine the carbapenem resistance among Enterotoxigenic Bacteroides fragilis (ETBF) isolated from patients candidates to colonoscopy in Shiraz, Iran. A total of 201 stool samples were gathered from 201 patients. The detection

Adherence of Bacteroides fragilis group species [PDF]

Infection and Immunity, 1991
The ability of piliated and capsulated Bacteroides fragilis and Bacteroides ovatus to adhere to intestinal cells and mucus was investigated. The adherence of piliated and capsulated strains was at least five times greater than the adherence of their nonpiliated and noncapsulated or capsulated only counterparts.

Haemagglutination by the Bacteroides fragilis group [PDF]

Journal of Medical Microbiology, 1986
Adhesive properties of five species of Bacteroides were compared by direct haemagglutination with erythrocytes of different origin. Only strains of Bacteroides fragilis agglutinated erythrocytes and different patterns of haemagglutination were observed. None of eight carbohydrates tested inhibited haemagglutination.

Anaerobic Profile of Intra-abdominal Infections – A 23-Year Retrospective Study

Journal of Pure and Applied Microbiology, 2023
Obligate anaerobes, which are part of normal intestinal flora are now gaining pathogenic potential by becoming more virulent and causing moderate to severe abdominal infections. Moreover, there is delay in initiation of appropriate antimicrobial therapy.

Lectinlike adhesins in the Bacteroides fragilis group [PDF]

Infection and Immunity, 1986
Lectinlike adhesins were identified in the Bacteroides fragilis group by using sugars immobilized on agarose beads either with whole bacteria by direct microscopic examination or with soluble extracts by immunoaffinoelectrophoresis. These two methods allowed the identification of two sugars reacting with whole bacteria and with the corresponding ...

Phylogenetic analysis reveals an ancient gene duplication as the origin of the MdtABC efflux pump. [PDF]

, 2020
The efflux pumps from the Resistance-Nodulation-Division family, RND, are main contributors to intrinsic antibiotic resistance in Gram-negative bacteria. Among this family, the MdtABC pump is unusual by having two inner membrane components.
