Periodontitis during pregnancy: The effect on the gut microbiome and intestinal inflammation

Journal of Periodontology, EarlyView.
Abstract Background Periodontitis has been epidemiologically associated with adverse pregnancy outcomes, but causality remains difficult to establish in humans due to confounding factors. This study uses a controlled murine model to examine the effects of experimentally induced periodontitis on the composition of the gut microbiota and gastrointestinal

Microbial communities and functional diversity in seafood

JSFA reports, EarlyView.
Abstract Functional diversity encompasses ecosystem processes that enhance adaptability to environmental change. This study explores the diversity of microorganisms associated with seafood. In this paper, we present our knowledge of microbial diversity in relation to seafood.

The reductive glycine pathway allows autotrophic growth of Desulfovibrio desulfuricans

Nature Communications, 2020
There are several pathways for CO2 fixation in photoautotrophic and chemoautotrophic microorganisms. Here, the authors provide experimental demonstration for the operation of the reductive glycine pathway in a natural microorganism, Desulfovibrio ...

Bacterial diversity on larval and female Mansonia spp. from different localities of Porto Velho, Rondonia, Brazil.

PLoS ONE, 2023
Studies based on the bacterial diversity present in Mansonia spp. are limited; therefore, the aim of this study was to investigate the bacterial diversity in females and larvae of Mansonia spp., describe the differences between the groups identified, and

Toxicity of Al to Desulfovibrio desulfuricans [PDF]

Applied and Environmental Microbiology, 2003
ABSTRACT The toxicity of Al to Desulfovibrio desulfuricans G20 was assessed over a period of 8 weeks in a modified lactate C medium buffered at four initial pHs (5.0, 6.5, 7.2, and 8.3) and treated with five levels of added Al (0, 0.01, 0.1, 1.0, and 10 mM).

Citrus depressa peel extract and its polymethoxyflavones mitigate acetaminophen‐induced chronic liver injury in mice through antioxidant activation, epigenetic regulation, and gut microbiota modulation

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Preventing chronic liver damage is essential for maintaining overall health and reducing the risk of serious liver diseases. Acetaminophen (APAP) overdose can lead to severe liver damage due to oxidative stress, and citrus fruits are rich in bioactive compounds that may have health benefits.

Chemical composition of Desulfovibrio desulfuricans lipid A [PDF]

Archives of Microbiology, 2010
Lipopolysaccharides also called endotoxins are an integral component of the outer membrane of Gram-negative bacteria. When released from the bacterial surface, they interact with a host immune system, triggering excessive inflammatory response. Lipid A is the biologically most active part of endotoxin, and its activity is modulated by the quantity ...

Carbon Monoxide as an Electron Donor for the Biological Reduction of Sulphate [PDF]

, 2010
Several strains of Gram-negative and Gram-positive sulphate-reducing bacteria (SRB) are able to use carbon monoxide (CO) as a carbon source and electron donor for biological sulphate reduction.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

Integrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...
