Effect of Intragenomic Sequence Heterogeneity among Multiple 16S rRNA Genes on Species Identification of Elizabethkingia

Microbiology Spectrum, 2022
Accurate identification of Elizabethkingia species mostly requires the use of molecular techniques, and 16S rRNA gene sequencing is generally considered the method of choice.

Microbial residence time is a controlling parameter of the taxonomic composition and functional profile of microbial communities. [PDF]

, 2019
A remaining challenge within microbial ecology is to understand the determinants of richness and diversity observed in environmental microbial communities.

16S rRNA oligonucleotide catalog data base

Nucleic Acids Research, 1984
We have developed a package of programs to create, maintain and manipulate a data base of 16S rRNA oligonucleotide catalog data. For the first time all the published catalog data is brought together in one place in a readily usable form. The package allows generation of dendrograms, facilitates searches for related oligonucleotides between catalogs ...

Ovine pedomics : the first study of the ovine foot 16S rRNA-based microbiome [PDF]

, 2011
We report the first study of the bacterial microbiome of ovine interdigital skin based on 16S rRNA by pyrosequencing and conventional cloning with Sanger-sequencing.

A Quantitative Sequencing Framework for Absolute Abundance Measurements of Mucosal and Lumenal Microbial Communities [PDF]

, 2020
A fundamental goal in microbiome studies is determining which microbes affect host physiology. Standard methods for determining changes in microbial taxa measure relative, rather than absolute abundances.

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.

Self-reinoculation with fecal flora changes microbiota density and composition leading to an altered bile-acid profile in the mouse small intestine [PDF]

, 2019
Background: The upper gastrointestinal tract plays a prominent role in human physiology as the primary site for enzymatic digestion and nutrient absorption, immune sampling, and drug uptake.

Construction of habitat-specific training sets to achieve species-level assignment in 16S rRNA gene datasets

Microbiome, 2020
Background The low cost of 16S rRNA gene sequencing facilitates population-scale molecular epidemiological studies. Existing computational algorithms can resolve 16S rRNA gene sequences into high-resolution amplicon sequence variants (ASVs), which ...

16S-ITGDB: An Integrated Database for Improving Species Classification of Prokaryotic 16S Ribosomal RNA Sequences

Frontiers in Bioinformatics, 2022
Analyzing 16S ribosomal RNA (rRNA) sequences allows researchers to elucidate the prokaryotic composition of an environment. In recent years, third-generation sequencing technology has provided opportunities for researchers to perform full-length sequence

Gut microbiota diversity is prognostic in metastatic hormone receptor‐positive breast cancer patients receiving chemotherapy and immunotherapy

Molecular Oncology, EarlyView.
In this exploratory study, we investigated the relationship between the gut microbiota and outcome in patients with metastatic hormone receptor‐positive breast cancer, treated in a randomized clinical trial with chemotherapy alone or chemotherapy in combination with immune checkpoint blockade.
