Co-occurrence of SARS-CoV-2 variants in rivers and sewage in India and Brazil.

The genomic monitoring of SARS-CoV-2 variants of concern (VOCs) in riverine and sewage water has been widely used as an epidemiological tool worldwide. But its utility for epidemiological assessments still needs to be evaluated in some areas. Our study encompassed thirteen Brazilian rivers spanning a vast urban expanse across the states of Rio de Janeiro, São Paulo, and Paraná.

We report the draft genome sequence of sp. strain JA880, which was isolated from a saltwater pond near Pata, Gujarat, India. The genome assembly contains 3,794,364 bp, with a GC content of 63.

Revisiting the taxonomy of the genus Rhodopirellula with the proposal for reclassification of the genus to Rhodopirellula sensu stricto, Aporhodopirellula gen. nov., Allorhodopirellula gen. nov. and Neorhodopirellula gen. nov.

The current genus Rhodopirellula consists of marine bacteria which belong to the family Pirellulaceae of the phylum Planctomycetota. Members of the genus Rhodopirellula are aerobic, mesophiles and chemoheterotrophs. The here conducted analysis built on 16S rRNA gene sequence and multi-locus sequence analysis based phylogenomic trees suggested that the genus is subdivided into four clades.

Paludisphaera rhizosphaereae sp. nov., a new member of the family Isosphaeraceae, isolated from the rhizosphere soil of Erianthus ravennae.

Two axenic cultures of Planctomycetota were isolated from distinct geographical locations of India. Strain JC665 was isolated from a rhizosphere soil of Loktak lake, Manipur, whereas strain JC747 was isolated from a soil sediment at Pallikkara village, Kerala, India. The two closely related strains shared the highest 16S rRNA gene sequence identity (94.

Neoroseomonas marina sp. nov., Isolated from a Beach Sand.

A pink-pigmented bacterium (strain JC162 = KCTC 32190) was isolated from a beach sand sample. Cells were Gram-stain-negative, coccoid, non-motile, and strictly aerobic. EzBioCloud BLAST search of 16S rRNA gene sequence showed that strain KCTC 32190 had the highest sequence identity to the members of the genus Neoroseomonas and was closely related to N.

A genomic overview including polyphasic taxonomy of Thalassoroseus pseudoceratinae gen. nov., sp. nov. isolated from a marine sponge, Pseudoceratina sp.

A pink-coloured, salt- and alkali-tolerant planctomycetal strain (JC658) with oval to pear-shaped, motile, aerobic, Gram-negative stained cells was isolated from a marine sponge, Pseudoceratina sp. Strain JC658 shares the highest 16S rRNA gene sequence identity with Maioricimonas rarisocia Mal4 (< 89.2%) in the family Planctomycetaceae.

Phylotaxogenomics for the Reappraisal of the Genus With the Creation of Six New Genera.

The genus is a significant group of bacteria which is invariably of great clinical and ecological importance. Previous studies have shown that the genus is polyphyletic in nature. Our present study focused on generating a lucid understanding of the phylogenetic framework for the re-evaluation and reclassification of the genus Phylogenetic studies based on the 16S rRNA gene and 92 concatenated genes suggested that the genus is heterogeneous, forming seven major groups.

Aquisphaera insulae sp. nov., a new member in the family Isosphaeraceae, isolated from the floating island of Loktak lake and emended description of the genus Aquisphaera.

Strain JC669 was isolated from a floating island of Loktak lake, Manipur, India and shares the highest 16S rRNA gene sequence identity with Aquisphaera giovannonii OJF2. The novel strain is aerobic, Gram negative, light pink-coloured, non-motile, NaCl intolerant and spherical to oval-shaped. It grows in the form of single cells or aggregates and possibly forms structures which appear like fruiting bodies.

Uncovering the hidden bacterial ghost communities of yeast and experimental evidences demonstrates yeast as thriving hub for bacteria.

Our major concern was to address "yeast endobacteria" which was based on a few reports in the recent past where bacteria may find yeast as a niche for survival. In this study, we report the microbiota of twenty-nine axenic yeast cultures recovered from different habitats based on their 16S rRNA gene-amplicon metagenomes. Yeasts were identified based on D1/D2 or ITS gene sequences.
