Virtual metagenome reconstruction from 16S rRNA gene sequences [PDF]

Nature Communications, 2012
Microbial ecologists have investigated roles of species richness and diversity in a wide variety of ecosystems. Recently, metagenomics have been developed to measure functions in ecosystems, but this approach is cost-intensive. Here we describe a novel method for the rapid and efficient reconstruction of a virtual metagenome in environmental microbial ...

Engineering CRISPR/Cas9 to mitigate abundant host contamination for 16S rRNA gene-based amplicon sequencing

Microbiome, 2020
Background High-throughput sequencing of bacterial 16S rRNA gene (16S-seq) is a useful and common method for studying bacterial community structures. However, contamination of the 16S rRNA genes from the mitochondrion and plastid hinders the sensitive ...

Performance of Conventional Urine Culture Compared to 16S rRNA Gene Amplicon Sequencing in Children with Suspected Urinary Tract Infection

Microbiology Spectrum, 2021
Because some organisms causing urinary tract infection (UTI) may be difficult to culture, examination of bacterial gene sequences in the urine may provide a more accurate view of bacteria present during a UTI.

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 ...

Molecular cloning of the rRNA genes of Prevotella bryantii B14

Acta Agriculturae Slovenica, 2000
Parts of the rRNA operons of anaerobic rumen bacteria Prevotella bryantii B14 were cloned. 350 colonies carrying pBluescriptII with HindIII DNA fragments were screened with 16S rDNA specific probe and six positive clones were obtained.

Yersinia spp. Identification Using Copy Diversity in the Chromosomal 16S rRNA Gene Sequence. [PDF]

PLoS ONE, 2016
API 20E strip test, the standard for Enterobacteriaceae identification, is not sufficient to discriminate some Yersinia species for some unstable biochemical reactions and the same biochemical profile presented in some species, e.g.

Microbial signatures in amniotic fluid at preterm birth and association with bronchopulmonary dysplasia

Respiratory Research, 2023
Background Microbiome dysbiosis can have long-lasting effects on our health and induce the development of various diseases. Bronchopulmonary dysplasia (BPD) is a multifactorial disease with pre- and postnatal origins including intra-amniotic infection as

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.

Taxonomy of anaerobic digestion microbiome reveals biases associated with the applied high throughput sequencing strategies [PDF]

, 2018
In the past few years, many studies investigated the anaerobic digestion microbiome by means of 16S rRNA amplicon sequencing. Results obtained from these studies were compared to each other without taking into consideration the followed procedure for ...

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.
