Formation of secondary allo-bile acids by novel enzymes from gut Firmicutes [PDF]

, 2022
The gut microbiome of vertebrates is capable of numerous biotransformations of bile acids, which are responsible for intestinal lipid digestion and function as key nutrient-signaling molecules.

Association of purine asymmetry, strand-biased gene distribution and PolC within Firmicutes and beyond: a new appraisal [PDF]

, 2014
strands of replication, Strand-biased Gene Distribution (SGD) and presence of two isoforms of DNA polymerase III alpha subunit, PolC and DnaE. Despite considerable research efforts, it is not clear whether the co-existence of PAS, PolC and/or SGD is an ...

Effects of Obesity and Feeding Avocado Extract on Gut Microbiota and Fecal Metabolomic Profile in Overweight/Obese Cats

Microbiology Research
Background/Objectives: Obesity is a growing problem in the feline population worldwide. An extract of unripe avocado (AvX) has been shown to attenuate gains in body weight and body fat in mice fed a high-fat diet.

Multi‐Targeting Carnosic Acid Kills Drug‐Resistant Helicobacter pylori With Narrow‐Spectrum Activity

Advanced Science, EarlyView.
Carnosic acid selectively eradicates drug‐resistant Helicobacter pylori through a multi‐targeted mechanism involving urease inhibition, membrane disruption, and biofilm eradication. It exhibits no detectable resistance, potent in vivo efficacy, and minimal impact on gut microbiota, positioning it as a promising narrow‐spectrum lead compound against ...

Gut Microbiota Dysbiosis and Metabolite Pathways in Heart Failure: A Systematic Review

Journal of Pure and Applied Microbiology
The gut microbiome plays a critical role in heart failure (HF) through immune, metabolic, and inflammatory pathways. Altered microbial composition and metabolites may contribute to HF pathogenesis and progression.

Diverse mechanisms regulate sporulation sigma factor activity in the Firmicutes [PDF]

Current Opinion in Microbiology, 2015
Sporulation allows bacteria to survive adverse conditions and is essential to the lifecycle of some obligate anaerobes. In Bacillus subtilis, the sporulation-specific sigma factors, σ(F), σ(E), σ(G), and σ(K), activate compartment-specific transcriptional programs that drive sporulation through its morphological stages.

A Single‐Cell Transcriptomic Atlas of the Ovine Rumen Microbiome Characterizes Lineage‐Specific Metabolic Shifts Associated with Host Heat Tolerance

Advanced Science, EarlyView.
An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...
