Accurate Identification of Common Pathogenic Nocardia Species: Evaluation of a Multilocus Sequence Analysis Platform and Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry. [PDF]

open access: yesPLoS ONE, 2016
Species identification of Nocardia is not straightforward due to rapidly evolving taxonomy, insufficient discriminatory power of conventional phenotypic methods and also of single gene locus analysis including 16S rRNA gene sequencing.

High-throughput sequencing of 16S rRNA gene amplicons : effects of extraction procedure, primer length and annealing temperature [PDF]

open access: yes, 2012
The analysis of 16S-rDNA sequences to assess the bacterial community composition of a sample is a widely used technique that has increased with the advent of high throughput sequencing.

Substrate-specific clades of active marine methylotrophs associated with a phytoplankton bloom in a temperate coastal environment [PDF]

open access: yes, 2008
Marine microorganisms that consume one-carbon (C1) compounds are poorly described, despite their impact on global climate via an influence on aquatic and atmospheric chemistry.

Characterising the Canine Oral Microbiome by Direct Sequencing of Reverse-Transcribed rRNA Molecules. [PDF]

open access: yesPLoS ONE, 2016
PCR amplification and sequencing of phylogenetic markers, primarily Small Sub-Unit ribosomal RNA (SSU rRNA) genes, has been the paradigm for defining the taxonomic composition of microbiomes.

Species-Specific Identification of Leptospiraceae by 16S rRNA Gene Sequencing [PDF]

open access: greenJournal of Clinical Microbiology, 2006
ABSTRACT The genus Leptospira is classified into 13 named species and 4 genomospecies based upon DNA-DNA reassociation studies. Phenotypic tests are unable to distinguish between species of Leptospira , and there is a need for a simplified molecular approach to the identification of

SituSeq: an offline protocol for rapid and remote Nanopore 16S rRNA amplicon sequence analysis

open access: yesISME Communications, 2023
Microbiome analysis through 16S rRNA gene sequencing is a crucial tool for understanding the microbial ecology of any habitat or ecosystem. However, workflows require large equipment, stable internet, and extensive computing power such that most of the ...

Linking 16S rRNA Gene Classification to amoA Gene Taxonomy Reveals Environmental Distribution of Ammonia-Oxidizing Archaeal Clades in Peatland Soils

open access: yesmSystems, 2021
A highly resolved taxonomy for ammonia-oxidizing archaea (AOA) based on the alpha subunit of ammonia monooxygenase (amoA) was recently established, which uncovered novel environmental patterns of AOA, challenging previous generalizations.

Amniotic fluid from healthy term pregnancies does not harbor a detectable microbial community [PDF]

open access: yes, 2018
Recent studies have conflicting data regarding the presence of intra-amniotic microbiota. Viral communities are increasingly recognized as important although overlooked components of the human microbiota.

Triplicate PCR Reactions for 16S rRNA Gene Amplicon Sequencing are Unnecessary [PDF]

open access: yesBioTechniques, 2019
Conventional wisdom holds that PCR amplification for sequencing should employ pooled replicate reactions to reduce bias due to jackpot effects and chimera formation. However, modern amplicon data analysis employs methods that may be less sensitive to such artifacts.
