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.

Comparative analysis of pyrosequencing and a phylogenetic microarray for exploring microbial community structures in the human distal intestine [PDF]

, 2009
BACKGROUND: Variations in the composition of the human intestinal microbiota are linked to diverse health conditions. High-throughput molecular technologies have recently elucidated microbial community structure at much higher resolution than was ...

Information about variations in multiple copies of bacterial 16S rRNA genes may aid in species identification.

PLoS ONE, 2019
Variable region analysis of 16S rRNA gene sequences is the most common tool in bacterial taxonomic studies. Although used for distinguishing bacterial species, its use remains limited due to the presence of variable copy numbers with sequence variation ...

Two different 16S rRNA genes in a mycobacterial strain [PDF]

Journal of Clinical Microbiology, 1996
Sequencing of the gene coding for 16S rRNA (16S rDNA) is a well-established method used to identify bacteria, particularly mycobacteria. Unique sequences allow identification of a particular genus and species. If more than one 16S rDNA is present on one mycobacterial genome, their sequences are assumed to be strictly or almost identical.

Phylogenetic analysis of microbial communities in different regions of the gastrointestinal tract in Panaque nigrolineatus, a wood-eating fish [PDF]

, 2012
The Neotropical detritivorous catfish Panaque nigrolineatus imbibes large quantities of wood as part of its diet. Due to the interest in cellulose, hemi-cellulose and lignin degradation pathways, this organism provides an interesting model system for the

The efficacy of partial 16S rRNA gene sequencing for precise determination of phylogenetic relatedness among Salmonellae

Scientific African, 2021
More than 2,600 Salmonella enterica serovars have been described based on the expression of the somatic and flagellar antigens. For epidemiological tracing, the use of Salmonellae serotyping is inefficient because strains within the same serovar could be

Sequence Diversity of Neisseria meningitidis 16S rRNA Genes and Use of 16S rRNA Gene Sequencing as a Molecular Subtyping Tool [PDF]

Journal of Clinical Microbiology, 2002
ABSTRACT We investigated the diversity of the primary sequences of 16S rRNA genes among Neisseria meningitidis strains (Men) and evaluated the use of this approach as a molecular subtyping tool. We aligned and compared a 1,417-bp fragment of the 16S rRNA gene from 264 Men strains of serogroups A, B, C, and
