Characterization of cephalosporinases from Bacteroides fragilis, Bacteroides thetaiotaomicron and Bacteroides vulgatus.

open access: yesThe Journal of Antibiotics, 1983
The susceptibility of 80 Bacteroides fragilis group strains isolated from clinical specimens to beta-lactam antibiotics was investigated by agar dilution method. Twenty strains showed high resistance to the antibiotics. The resistance level of the isolates to cephaloridine was related to the amount of beta-lactamase activity (cephalosporinase; CSase ...

Human gut Bacteroides capture vitamin B12 via cell surface-exposed lipoproteins. [PDF]

open access: yes, 2018
Human gut Bacteroides use surface-exposed lipoproteins to bind and metabolize complex polysaccharides. Although vitamins and other nutrients are also essential for commensal fitness, much less is known about how commensal bacteria compete with each other

Role of gut microbiota in the aetiology of obesity: proposed mechanisms and review of the literature [PDF]

open access: yes, 2016
The aetiology of obesity has been attributed to several factors (environmental, dietary, lifestyle, host, and genetic factors); however none of these fully explain the increase in the prevalence of obesity worldwide.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Metabolic changes associated with polysaccharide utilization reduce susceptibility to some β-lactams in Bacteroides thetaiotaomicron

open access: yesmSphere
Antibiotic therapy alters bacterial abundance and metabolism in the gut microbiome, leading to dysbiosis and opportunistic infections. Bacteroides thetaiotaomicron (Bth) is both a commensal in the gut and an opportunistic pathogen in other body sites ...

THE BIOLOGICAL AND STRUCTURAL CHARACTERIZATION OF TRANSFERABLE BACTEROIDES R PLASMIDS [PDF]

open access: yes, 1979
In this literature review I will briefly describe the general biology of transferable antibiotic resistance in bacteria, the genetic elements involved (plasmids) and several specific plasmid associated phenotypes.

Gene transfer in the GI tract and oral cavity [PDF]

open access: yes, 2000
Gene transfer is important in spreading antibiotic resistance and other traits such as virulence factors. In this review the molecular mechanisms of gene transfer are outlined and the biological consequences of bacterial gene transfer in the GI tract and

Viability of Rhizobium bacteroids [PDF]

open access: yesApplied and Environmental Microbiology, 1977
Bacteroids prepared from nodules of soybean and bean were tested for viability. Contrary to the prevailing view that bacteroids are nonviable, it was found that bacteroids averaged 90% viability, irrespective of Rhizobium strain, nodule age, or nodule environment.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

open access: yesFEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Gut Bacteroides act in a microbial consortium to cause susceptibility to severe malaria

open access: yesNature Communications, 2023
Malaria is caused by Plasmodium species and remains a significant cause of morbidity and mortality globally. Gut bacteria can influence the severity of malaria, but the contribution of specific bacteria to the risk of severe malaria is unknown.
