Adaptations in gut Bacteroidales facilitate stable co-existence with their lytic bacteriophages

Gut Microbes
Bacteriophages (phages) and bacteria within the gut microbiome persist in long-term stable coexistence. These interactions are driven by eco-evolutionary dynamics, where bacteria employ a variety of mechanisms to evade phage infection, while phages rely ...

Low-input RNA-seq suggests metabolic specialization underlying morphological heterogeneity in a gut commensal bacterium

Cell Reports
Summary: Isogenic bacteria can be phenotypically diverse. This heterogeneity is evident in the Bacteroidota, a predominant phylum of the human gut microbiota.

Bacterial constipation: Mucin-degrading intestinal commensal bacteria cause constipation

Gut Microbes
The contribution of gut microbes to constipation remains mechanistically underexplored, despite constipation being one of the most prevalent gastrointestinal disorders.

SICLE: A high-throughput tool for extracting evolutionary relationships from phylogenetic trees

, 2016
We present the phylogeny analysis software SICLE (Sister Clade Extractor), an easy-to-use, high- throughput tool to describe the nearest neighbors to a node of interest in a phylogenetic tree as well as the support value for the relationship.

Differential toll-like receptor 2 activation by Akkermansia muciniphila and Bacteroides thetaiotaomicron mediates the beneficial effects of Fu brick tea polysaccharide against colitis

Pharmacological Research
Fu Brick Tea Polysaccharide (FBTP) ameliorates dextran sulfate sodium (DSS)-induced colitis in mice. However, the key intestinal bacterial strains and downstream molecular mechanisms mediating these protective effects remain unclear.

Identification of a New Family of Enzymes with Potential \u3cem\u3eO\u3c/em\u3e-acetylpeptidoglycan esterase activity in both Gram-positive and Gram-negative bacteria [PDF]

, 2005
Background: The metabolism of the rigid bacterial cell wall heteropolymer peptidoglycan is a dynamic process requiring continuous biosynthesis and maintenance involving the coordination of both lytic and synthetic enzymes.

Gut bacteria responding to dietary change encode sialidases that exhibit preference for red meat-associated carbohydrates. [PDF]

, 2019
Dietary habits have been associated with alterations of the human gut resident microorganisms contributing to obesity, diabetes and cancer1. In Western diets, red meat is a frequently eaten food2, but long-term consumption has been associated with ...

Structure-dependent degradation of milk oligosaccharides by newly isolated intestinal commensal bacterial strains from suckling piglets and rabbits

BMC Microbiology
Background Mammalian milk oligosaccharides serve as the first natural prebiotics for newborns, promoting the development of a beneficial gut microbiota. The ability of bacteria to use these complex sugars depends on their structure, but data are limited ...
