The Cultivation of Halophilic Microalgae Shapes the Structure of Their Prokaryotic Assemblages.

The influence of microalgae on the formation of associated prokaryotic assemblages in halophilic microbial communities is currently underestimated. The aim of this study was to characterize shifts in prokaryotic assemblages of halophilic microalgae upon their transition to laboratory cultivation. Monoalgal cultures belonging to the classes Chlorodendrophyceae, Bacillariophyceae, Trebouxiophyceae, and Chlorophyceae were isolated from habitats with intermediate salinity, about 100 g/L, nearby Elton Lake (Russia).

Unexpected ubiquity of heart-shaped scale morphotype in Centroplasthelida (Haptista): Ancestral trait or multiple acquisitions?

Centrohelids (Haptista: Centroplasthelida) are axopodial protists with a remarkable diversity of external siliceous scale morphologies. It is believed that the last common ancestor of centrohelids had a double layer of siliceous scales composed of plate scales closer to a cell surface and spine scales radiating outwards. The characteristic morphotype of spine scales with a heart-shaped base was once believed to be a unique feature of the genus Choanocystis, as it was defined by Siemensma and Roijackers (1988).

Macrophage Phenotype in Combination with Tumor Microbiome Composition Predicts RCC Patients' Survival: A Pilot Study.

The identification of new prognostic markers of renal cell carcinoma (RCC) is an urgent problem in oncourology. To investigate the potential prognostic significance of tumor microbiome and stromal inflammatory markers, we studied a cohort of 66 patients with RCC (23 clear cell RCC, 19 papillary RCC and 24 chromophobe RCC). The microbiome was analyzed in tumor and normal tissue by 16S rRNA amplicon sequencing.

Cappable-Seq Reveals Specific Patterns of Metabolism and Virulence for Typhimurium Intracellular Survival within .

The bacterial pathogen , which causes enteritis, has a broad host range and extensive environmental longevity. In water and soil, Salmonella interacts with protozoa and multiplies inside their phagosomes. Although this relationship resembles that between and mammalian phagocytes, the interaction mechanisms and bacterial genes involved are unclear.

Data on rumen and faeces microbiota profiles of Yakutian and Kalmyk cattle revealed by high-throughput sequencing of 16S rRNA gene amplicons.

It is known that the rumen microbiome directly or indirectly contributes to animal production, and may be a prospective target for mitigation of greenhouse gas emissions [1]. At the same time, feed types and components of diet can influence the composition of the rumen microbiome [2,3]. Fluctuations in the composition of the digestive tract microbiota can alter the development, health, and productivity of cattle [4].

Data on draft genome sequence of sp. SAM-B isolated from a mineral cold spring located in Tyva, southern Siberia.

sp. SAM-B was isolated from Uzharlyg Mineral Cold Spring, Samagaltay Settlement, Republic of Tyva (Southern Siberia), Russian Federation. A whole genome sequencing of sp.

Dataset for transcriptome analysis of subsp. serovar Typhimurium strain 14028S response to starvation.

is an ubiquitous pathogen throughout the world causing gastroenteritis in humans and animals. Survival of pathogenic bacteria in the external environment may be associated with the ability to overcome the stress caused by starvation. The bacterial response to starvation is well understood in laboratory cultures with a sufficiently high cell density.

Transcriptomic data of subsp. serovar Typhimurium str. 14028S treated with novobiocin.

In enteric bacteria, DNA supercoiling is highly responsive to environmental conditions. Host specific features of environment serve as cues for the expression of genes required for colonization of host niches via changing supercoiling [1]. It has been shown that substitution at position 87 of GyrA of str.

Multiple Euryhaline Lineages of Centrohelids (Haptista: Centroplasthelida) in Inland Saline Waters Revealed with Metabarcoding.

The diversity of centrohelids in inland saline waters was studied with metabarcoding for the first time. The fragment of V6-V7 regions of 18S rDNA was sequenced with newly designed primers. Obtained OTUs were identified with molecular phylogenetic analysis and comparison of the signatures in 39es9 hairpin of V7.

Metagenomic analysis of mycobacterial transrenal DNA in patients with HIV and tuberculosis coinfection.

The existence of "transrenal" DNA (tr-DNA), i.e. cell-free DNA that has distributed through the renal barrier to the urine, was first shown from a pathogen in 2000 (Botezatu et al.

Pinjata ruminata gen. et sp. n.-A New Member of Centrohelid Family Yogsothothidae (Haptista: Centroplasthelida) from the Brackish River.

A new genus and species of centrohelid heliozoan Pinjata ruminata from the Tuzlukkol' River (Orenburg Region of Russia) and Gor'koe Lake (Chelyabinsk Region of Russia) is studied with light- and electron microscopy. Pinjata ruminata has two types of plate scales, partially running up the sides of the axopodia. Inner plate scales (3.
