Cephalosporinases associated with outer membrane vesicles released by Bacteroides spp. protect gut pathogens and commensals against beta-lactam antibiotics [PDF]
, 2014 Objectives: To identify β-lactamase genes in gut commensal Bacteroides species and to assess the impact of these enzymes, when carried by outer membrane vesicles (OMVs), in protecting enteric pathogens and commensals.

Evaluation of xylan fermentation for the identification of Bacteroides ovatus and Bacteroides thetaiotaomicron [PDF]
Journal of Clinical Microbiology, 1985 The reliability of xylan fermentation in distinguishing Bacteroides ovatus from Bacteroides thetaiotaomicron was examined with strains previously identified by DNA homology studies or bacteriophage sensitivity testing or both. All of the 12 B. ovatus strains produced acid ranging from pH 5.0 to 5.6 in peptone-yeast-xylan broth; none of the 19 B ...

High resolution crystal structure of the Endo-N-acetyl-beta-D-glucosaminidase responsible for the deglycosylation of hypocrea jecorina cellulases [PDF]
, 2012 Endo-N-acetyl-beta-D-glucosaminidases (ENGases) hydrolyze the glycosidic linkage between the two N-acetylglucosamine units that make up the chitobiose core of N-glycans. The endo-N-acetyl-beta-D-glucosaminidases classified into glycoside hydrolase family

The NQR Complex Regulates the Immunomodulatory Function of Bacteroides thetaiotaomicron. [PDF]
J Immunol, 2023 Abstract The gut microbiome and intestinal immune system are engaged in a dynamic interplay that provides myriad benefits to host health. However, the microbiome can also elicit damaging inflammatory responses, and thus establishing harmonious immune-microbiome interactions is essential to maintain homeostasis.

16S rRNA gene profiling and genome reconstruction reveal community metabolic interactions and prebiotic potential of medicinal herbs used in neurodegenerative disease and as nootropics. [PDF]
, 2019 The prebiotic potential of nervine herbal medicines has been scarcely studied. We therefore used anaerobic human fecal cultivation to investigate whether medicinal herbs commonly used as treatment in neurological health and disease in Ayurveda and other ...

Structural genomics analysis of uncharacterized protein families overrepresented in human gut bacteria identifies a novel glycoside hydrolase. [PDF]
, 2014 BackgroundBacteroides spp. form a significant part of our gut microbiome and are well known for optimized metabolism of diverse polysaccharides. Initial analysis of the archetypal Bacteroides thetaiotaomicron genome identified 172 glycosyl hydrolases and

Structure- and context-based analysis of the GxGYxYP family reveals a new putative class of glycoside hydrolase. [PDF]
, 2014 BackgroundGut microbiome metagenomics has revealed many protein families and domains found largely or exclusively in that environment. Proteins containing the GxGYxYP domain are over-represented in the gut microbiota, and are found in Polysaccharide ...

Multiple TonB homologs are important for carbohydrate utilization by <i>Bacteroides thetaiotaomicron</i>. [PDF]
J Bacteriol, 2023 Abstract The human gut microbiota is able to degrade otherwise undigestible polysaccharides, largely through the activity of the Bacteroides . Uptake of polysaccharides into Bacteroides is controlled by TonB-dependent transporters (TBDT) whose ...

Comparative serology of two clinical isolates of Bacteroides fragilis and Bacteroides thetaiotaomicron [PDF]
Journal of Clinical Microbiology, 1979 Antiserum prepared in rabbits against Bacteroides fragilis showed numerous bands when reacted with B. fragilis antigen in Ouchterlony plates. This antiserum also reacted with Bacteroides thetaiotaomicron and showed one band of apparent identity with B. fragilis.
