Superoxide dismutase in Bacteroides fragilis and related Bacteroides species [PDF]

Journal of Clinical Microbiology, 1977
Superoxide dismutase (SOD) activity was demonstrated in cell-free extracts of Bacteroides fragilis, Bacteroides vulgatus, Bacteroides distasonis, Bacteroides ovatus, and Bacteroides thetaiotaomicron. The strains were grown under anaerobic conditions in Trypticase soy broth, and the specific activity of SOD in the extracts was, in most strains, higher ...

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

, 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]

, 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.

Microenvironment Self‐Adaptive Nanoarmor to Address Adhesion‐ and Colonization‐Related Obstacles in Impaired Intestine Promote Bacteriotherapy Against Parkinson's Disease

Advanced Science, EarlyView.
A microenvironment self‐adaptive nanoarmor is developed to effectively address the adhesion‐ and colonization‐related challenges posed by multiple physiological and pathological characteristics in the intestine. L. plantarum@MPN@CS showed significant therapeutic potential in treating Parkinson's disease (PD), a model for extraintestinal disorders, as ...

Conformable Device for Independent Measurements of Mucosal and Vascular Barriers in a Complex In Vitro Intestinal Model

Advanced Science, EarlyView.
Development of more complex in vitro models necessitates the development of improved monitoring approaches. This work demonstrates a novel conformable device capable of measuring the resistance of two cell barriers within a single model independently, a significant advantage over conventional trans‐epithelial/endothelial electrical resistance (TEER ...

A new Illumina MiSeq high‐throughput sequencing‐based method for evaluating the composition of the Bacteroides community in the intestine using the rpsD gene sequence

Microbial Biotechnology, 2021
Summary Bacteroides is a bacterial genus that is known to closely interact with the host. The potential role of this genus is associated with its ecological status and distribution in the intestine. However, the current 16S V3–V4 region sequencing method

Enterotype Bacteroides Is Associated with a High Risk in Patients with Diabetes: A Pilot Study

Journal of Diabetes Research, 2020
Background More and more studies focus on the relationship between the gastrointestinal microbiome and type 2 diabetes, but few of them have actually explored the relationship between enterotypes and type 2 diabetes. Materials and Methods.

MGM as a Large‐Scale Pretrained Foundation Model for Microbiome Analyses in Diverse Contexts

Advanced Science, EarlyView.
We present the Microbial General Model (MGM), a transformer‐based foundation model pretrained on over 260,000 microbiome samples. MGM learns contextualized microbial representations via self‐supervised language modeling, enabling robust transfer learning, cross‐regional generalization, keystone taxa discovery, and prompt‐guided generation of realistic,

Changes in the intestinal microbiota after a short period of dietary over-indulgence, representative of a holiday or festival season [PDF]

, 2008
The effects on the intestinal microbiota of a short period of marginal over-eating, characteristic of holiday or festival periods, were investigated in a pilot study.
