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 ...

Prophages in Bacteroides fragilis: Distribution and genetic diversity
HeliyonObjectives: We evaluated the distribution, epidemiology, and relationships of prophage regions among 500 Bacteroides fragilis group genomes. Methods: Average nucleotide identity (ANI) analysis was carried out to characterize the genome at the species ...

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.

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 ...

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.

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.
