Recent progress in our understanding of peptidoglycan assembly in Firmicutes [PDF]

open access: yesCurrent Opinion in Microbiology, 2021
Years of intense research have shown that the assembly of peptidoglycan, the extracellular mesh-like polymer surrounding the bacterial cell, is incredibly complex. It requires a suite of reactions catalyzed by dynamic macromolecular protein complexes whose localization and activity should be finely regulated in space and time.

Microbiota and bile acid profiles in retinoic acid-primed mice that exhibit accelerated liver regeneration. [PDF]

open access: yes, 2015
Background & aimsAll-trans Retinoic acid (RA) regulates hepatic lipid and bile acid homeostasis. Similar to bile acid (BA), RA accelerates partial hepatectomy (PHx)-induced liver regeneration.

Rectal Microbiome Composition Correlates with Humoral Immunity to HIV-1 in Vaccinated Rhesus Macaques. [PDF]

open access: yes, 2019
The microbiome is an integral and dynamic component of the host and is emerging as a critical determinant of immune responses; however, its influence on vaccine immunogenicity is largely not well understood.

Veillonella, Firmicutes: Microbes disguised as Gram negatives

open access: yesStandards in Genomic Sciences, 2013
The Firmicutes represent a major component of the intestinal microflora. The intestinal Firmicutes are a large, diverse group of organisms, many of which are poorly characterized due to their anaerobic growth requirements. Although most Firmicutes are Gram positive, members of the class Negativicutes, including the genus Veillonella, stain Gram ...

Composition and Diversity of Natural Bacterial Communities in Mabisi, a Traditionally Fermented Milk

open access: yesFrontiers in Microbiology, 2020
Many traditionally fermented milk products such as mabisi involve spontaneous fermentation, which can result in bacterial community composition variation due to selection pressure.

Structural Analysis of Polarizing Indels Argues the Root of the Tree of Life is Near the Chloroflexi [PDF]

open access: yes, 2009
Determining which branches of the tree of life have derived features narrows down the possible location of the root. Currently the polarization of indels done by Lake _et al_.^1-5^ and the polarizing transitions of Cavalier-Smith^6^ arrive at ...

Marine Microalgae, Spirulina maxima-Derived Modified Pectin and Modified Pectin Nanoparticles Modulate the Gut Microbiota and Trigger Immune Responses in Mice

open access: yesMarine Drugs, 2020
This study evaluated the modulation of gut microbiota, immune responses, and gut morphometry in C57BL/6 mice, upon oral administration of S. maxima-derived modified pectin (SmP, 7.5 mg/mL) and pectin nanoparticles (SmPNPs; 7.5 mg/mL).

Association of the gut microbiota with clinical variables in obese and lean Emirati subjects

open access: yesFrontiers in Microbiology, 2023
BackgroundGrowing evidence supports the role of gut microbiota in obesity, yet exact associations remain largely unknown. Specifically, very little is known about this association in the Emirati population.MethodsWe explored differences in gut microbiota
