Transferable resistance to cefoxitin in Bacteroides thetaiotaomicron [PDF]

Antimicrobial Agents and Chemotherapy, 1982
Cefoxitin resistance, but not resistance to clindamycin, erythromycin, lincomycin, or tetracycline, was transferred by a conjugation-like process from Bacteroides thetaiotaomicron UN101, a clinical isolate haboring four kinds of plasmids, to other Bacteroides species. Of a sample of 20 cefoxitin-resistant transconjugants, 8 contained all 4 plasmids, 10

Bacteroides thetaiotaomicron Outer Membrane Vesicles Modulate Virulence of Shigella flexneri

mBio, 2022
The role of the gut microbiota in the pathogenesis of Shigella flexneri remains largely unknown. To understand the impact of the gut microbiota on S.

Incorporation of leucine into phospholipids of Bacteroides thetaiotaomicron [PDF]

Journal of Bacteriology, 1981
L-[4,5-3H]- or L-[U-14C]leucine was incorporated by Bacteroides thetaiotaomicron into acid-precipitable material even when the bacteria were treated with concentrations of tetracycline high enough to prevent growth. Similar results were obtained when L-[2,3,4-3H]valine or L-[4,5-3H]isoleucine was used instead of leucine.

Extraction and Evaluation of Outer Membrane Vesicles from Two Important Gut Microbiota Members, Bacteroides fragilis and Bacteroides thetaiotaomicron

Cell Journal, 2020
Objective: The gastrointestinal tract (GI) is colonized by a complex microbial community of gut microbiota. Bacteroides spp. have significant roles in gut microbiota and they host interactions by various mechanisms, including outer membrane vesicle ...

Investigation and Alteration of Organic Acid Synthesis Pathways in the Mammalian Gut Symbiont Bacteroides thetaiotaomicron

Microbiology Spectrum, 2022
Members of the gut-dwelling Bacteroides genus have remarkable abilities in degrading a diverse set of fiber polysaccharide structures, most of which are found in the mammalian diet.

Capsular Polysaccharide Cross-Regulation Modulates Bacteroides thetaiotaomicron Biofilm Formation

mBio, 2020
Bacteroides thetaiotaomicron is one of the most abundant gut symbiont species, whose contribution to host health through its ability to degrade dietary polysaccharides and mature the immune system is under intense scrutiny.

Interaction of Bacteroides fragilis and Bacteroides thetaiotaomicron with the kallikrein–kinin system [PDF]

Microbiology, 2011
Many bacterial pathogens interfere with the contact system (kallikrein–kinin system) in human plasma. Activation of this system has two consequences: cleavage of high-molecular-mass kininogen (HK) resulting in release of the potent proinflammatory peptide bradykinin, and initiation of the intrinsic pathway of coagulation.

Chemoproteomic identification of a DPP4 homolog in Bacteroides thetaiotaomicron

Nature Chemical Biology, 2023
Serine hydrolases play important roles in signaling and human metabolism, yet little is known about their functions in gut commensal bacteria. Using bioinformatics and chemoproteomics, we identify serine hydrolases in the gut commensal Bacteroides thetaiotaomicron that are specific to the Bacteroidetes phylum.

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 ...

Prebiotic effects of yeast mannan, which selectively promotes Bacteroides thetaiotaomicron and Bacteroides ovatus in a human colonic microbiota model

Scientific Reports, 2020
Yeast mannan (YM) is an indigestible water-soluble polysaccharide of the yeast cell wall, with a notable prebiotic effect on the intestinal microbiota. We previously reported that YM increased Bacteroides thetaiotaomicron abundance in in vitro rat faeces
