Molecular Characterization of Plasmids Harbored by Actinomycetes Isolated From the Great Salt Plains of Oklahoma Using PFGE and Next Generation Whole Genome Sequencing

Frontiers in Microbiology, 2018
One of the unique features of actinomycetes, especially the genus Streptomyces, is the presence of linear plasmids. These range in size from 12 to 600 kb, and are often termed mega-plasmids.

Intestinal microbiome alterations in pediatric epilepsy: Implications for seizures and therapeutic approaches

Epilepsia Open, EarlyView.
Abstract The intestinal microbiome plays a pivotal role in maintaining host health through its involvement in gastrointestinal, immune, and central nervous system (CNS) functions. Recent evidence underscores the bidirectional communication between the microbiota, the gut, and the brain and the impact of this axis on neurological diseases, including ...

High-throughput sequencing of 16S rRNA gene amplicons : effects of extraction procedure, primer length and annealing temperature [PDF]

, 2012
The analysis of 16S-rDNA sequences to assess the bacterial community composition of a sample is a widely used technique that has increased with the advent of high throughput sequencing.

Construction of Chronic Kidney Disease Mouse Model Induced by Diets With Different Adenine Content

Food Safety and Health, EarlyView.
By administering a 4 weeks adenine diet to C57BL/6J mice, we identified 0.2% adenine in purified feed as the optimal chronic kidney disease model. This model induces severe renal damage, gut dysbiosis, uremic toxin accumulation, and CKD mineral bone disorder, providing a clinically relevant platform for mechanistic and therapeutic studies.

Functional Traits Co-Occurring with Mobile Genetic Elements in the Microbiome of the Atacama Desert [PDF]

, 2019
Mobile genetic elements (MGEs) play an essential role in bacterial adaptation and evolution. These elements are enriched within bacterial communities from extreme environments. However, very little is known if specific genes co-occur with MGEs in extreme

Urolithin A, a Diet‐Derived Gut Microbial Metabolite Against Pulmonary Hypertension Identified via Molecular Docking, Molecular Dynamics and Surface Plasmon Resonance

Food Safety and Health, EarlyView.
Urolithin A, a gut microbial metabolite, binds TNF to suppress proliferation, inflammation, and oxidative stress, offering a promising microbe‐derived therapeutic avenue for pulmonary hypertension. ABSTRACT Pulmonary hypertension (PH) is a complex and multifactorial disease that poses a significant clinical challenge.

Evolution of substrate specificity in a retained enzyme driven by gene loss. [PDF]

, 2017
The connection between gene loss and the functional adaptation of retained proteins is still poorly understood. We apply phylogenomics and metabolic modeling to detect bacterial species that are evolving by gene loss, with the finding that ...

Gut microbiota of migrating wild rabbit fish (Siganus guttatus) larvae have low spatial and temporal variability [PDF]

, 2019
We investigated the gut microbiota of rabbit fish larvae at three locations in Vietnam (ThuanAn-northern, QuangNam-intermediate, BinhDinh-southern sampling site) over a three-year period. In the wild, the first food for rabbit fish larvae remains unknown,

Ribosomal RNA operon copy number: A trait‐informed framework to close the microbial cultivation gap

iMetaOmics, EarlyView.
The vast majority of microbes remain uncultured, constraining functional validation and limiting microbiome‐based applications. We show that ribosomal RNA operon (rrn) copy number—a stable, phylogenetically conserved genomic trait—is strongly correlated with cultivation outcomes across ecosystems.
