16S rRNA Methylase–producing, Gram-Negative Pathogens, Japan

Emerging Infectious Diseases, 2007
To investigate the exact isolation frequency of 16S rRNA methylase–producing, gram-negative pathogenic bacteria, we tested 87,626 clinical isolates from 169 hospitals. Twenty-six strains from 16 hospitals harbored 16S rRNA methylase genes, which suggests

Variable copy number, intra-genomic heterogeneities and lateral transfers of the 16S rRNA gene in Pseudomonas. [PDF]

PLoS ONE, 2012
Even though the 16S rRNA gene is the most commonly used taxonomic marker in microbial ecology, its poor resolution is still not fully understood at the intra-genus level.

Reconstructing 16S rRNA genes in metagenomic data [PDF]

Bioinformatics, 2015
Abstract Metagenomic data, which contains sequenced DNA reads of uncultured microbial species from environmental samples, provide a unique opportunity to thoroughly analyze microbial species that have never been identified before. Reconstructing 16S ribosomal RNA, a phylogenetic marker gene, is usually required to analyze the composition

Characterization of spiny lobsters from Bangladesh waters using morphology, COI and 16S rRNA sequences

Heliyon, 2022
This study aims to taxonomically identify and characterise the phylogenetic relationships of spiny lobsters based on mitochondrial cytochrome c oxidase I (COI) and 16S rRNA genes from Bangladesh waters.

Taxonomy of the canine Mollicutes by 16S rRNA gene and 16S/23S rRNA intergenic spacer region sequence comparison [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2004
The taxonomy of canine Mollicutes is described, based on phylogenetic analysis of 16S rRNA gene and 16S/23S rRNA intergenic spacer (IGS) region sequences. The nucleotide sequences of the 16S rRNA gene of two untyped mycoplasmas and the IGS region of 11 Mycoplasma species were determined and used for phylogenetic analysis.

Choice of 16S Ribosomal RNA Primers Impacts Male Urinary Microbiota Profiling

Frontiers in Cellular and Infection Microbiology, 2022
Accessibility to next-generation sequencing (NGS) technologies has enabled the profiling of microbial communities living in distinct habitats. 16S ribosomal RNA (rRNA) gene sequencing is widely used for microbiota profiling with NGS technologies.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Amplicon Sequence Variants Artificially Split Bacterial Genomes into Separate Clusters

mSphere, 2021
16S rRNA gene sequencing has engendered significant interest in studying microbial communities. There has been tension between trying to classify 16S rRNA gene sequences to increasingly lower taxonomic levels and the reality that those levels were ...

Activity profiles for marine sponge-associated bacteria obtained by 16S rRNA vs 16S rRNA gene comparisons [PDF]

The ISME Journal, 2010
Abstract The phylogenetic diversity of microorganisms in marine sponges is becoming increasingly well described, yet relatively little is known about the activities of these symbionts. Given the seemingly favourable environment provided to microbes by their sponge hosts, as indicated by the extraordinarily high abundance of sponge ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
