31 results for “bacterial abundance”
Bacterial abundances by flow cytometry - collected from the Southern Ocean in the austral summer of 2016/2017, during the Antarctic Circumnavigation Expedition.
<p>Seawater surface samples (5 m) were collected every 6 hours from the ship’s underway pump. In addition, vertical profiles (6 depths, generally from 5 to 100-150 m) were sampled from CTD casts using a SBE 911 Plus attached to a rosette of 24 12-L PVC Niskin bottles. This dataset presents the abundances of high-DNA containing and low-DNA containing bacteria from seawater samples collected from the ship’s underway pump and CTDs. Samples were fixed with paraformaldehyde and glutaraldehyde and stored at -80ºC. In the lab, they were thawed, stained with SYBR-Green, and counted in a Cube 8 flow cytometer (SYSMEX PARTEC) based on green fluorewscence. Samples were collected around the Southern Ocean on the R/V Akademik Tryoshnikov in the austral summer of 2016/2017, as part of the Antarctic Circumnavigation Expedition (ACE).</p>
Relative abundance tables for bacterial species, pathways, ARGs, and VFGs in "Gut Microbial Community Structure, Metabolic Signature, and Resistome in Dyslipidemia: Insights from Metagenomic Sequencing"
<p>Dyslipidemia, characterized by abnormal blood lipid levels, is a significant risk factor for cardiovascular disease. Emerging evidence suggests that the gut microbiota plays a role in lipid metabolism, although findings across studies have varied. In this study, we analyzed the gut microbiota, metabolic pathways, predicted gut metabolites, and resistome in 1384 participants (895 with dyslipidemia cases and 489 controls) using shotgun metagenomic sequencing. Our results revealed that Bacteroides caccae was enriched in dyslipidemia cases, potentially contributing to inflammation and altered lipid metabolism, while Coprococcus eutactus and Coprococcus catus, known producers of short-chain fatty acids (SCFAs) in lipid regulation, and Blautia obeum, known to be positively impacted by SCFAs, were more abundant in controls. We also identified an enrichment of the dTDP-beta-D-fucofuranose biosynthesis pathway gene family, which is linked to bacterial pathogenicity, in dyslipidemia cases, with Bacteroides stercoris contributing strongly. Dyslipidemia cases exhibited depleted glycogen and peptidoglycan biosynthesis pathways, potentially impairing energy storage and immune function, alongside distinct metabolic profiles, including decreased pseudouridine, which may affect RNA metabolism. Furthermore, we observed a higher abundance of antibiotic-resistance genes, particularly tetQ, in dyslipidemia cases, suggesting a link between gut resistome and metabolic disorders. These findings provide new insights into how dysbiosis of the gut microbiota may contribute to the pathophysiology of dyslipidemia, offering potential avenues for microbiome-based interventions in personalized medicine.</p>

Bacterial abundance and produciton at the Palmer Station LTER sites B and E in May 2011 and 2012
The data described here were collected as part of a study of photoheterotrophic microbes in Antarctic waters (NSF OPP 0838830). This sampling was conducted in May outside of the LTER sampling season at Palmer Station. Samplng was conducted by pumping water from a depth of 1 m into carboys that were returned to the lab.
