metaSPARSim: a 16S rRNA gene sequencing count data simulator

BMC Bioinformatics, 2019
Background In the last few years, 16S rRNA gene sequencing (16S rDNA-seq) has seen a surprisingly rapid increase in election rate as a methodology to perform microbial community studies.

16S rDNA Profiling to Reveal the Influence of Seed-Applied Biostimulants on the Rhizosphere of Young Maize Plants [PDF]

, 2018
In an open field trial on two agricultural soils in NW Italy, the impact of two seed-applied biostimulants on the rhizosphere bacterial community of young maize plants was evaluated.

What is broad-range 16S rDNA PCR? [PDF]

Archives of disease in childhood - Education & practice edition, 2017
PCRs have revolutionised the detection of bacteria in clinical samples since their widespread introduction in the 1990s.1 Quantitative PCR (qPCR), also known as specific PCR, involves the targeting of particular bacterial species. The technique uses specific primers (short strands of nucleic acid needed to initiate DNA replication) and fluorescent ...

Identification of Lactic Acid Bacteria From the Crust and Inner Part of Artisanally Produced Mihaliç Cheese Sold With Salty and Low Salty Label by Using MALDI-TOF-MS and 16S rDNA Sequencing. [PDF]

Food Sci Nutr
Our results indicate that streptococci were predominant, particularly in the crust, and that Lacticaseibacillus paracasei/casei and Limosilactobacillus fermentum were the most common lactobacilli, with notable differences between SMC and LSMC samples. Furthermore, the presence of Streptococcus gallolyticus ssp. macedonicus and Str.

Anoxic nitrification in marine sediments [PDF]

, 2004
Nitrate peaks are found in pore-water profiles in marine sediments at depths considerably below the conventional zone of oxic nitrification. These have been interpreted to represent nonsteady- state effects produced by the activity of nitrifying ...

Phenotypic, Molecular and Symbiotic Characterization of the Rhizobial Symbionts of Desmanthus paspalaceus (Lindm.) Burkart That Grow in the Province of Santa Fe, Argentina [PDF]

, 2014
Desmanthus paspalaceus (Lindm.) Burkart belongs to the D. virgatus complex, subfamily Mimosoidae. The known potential as livestock fodder of several of these legumes prompted us to undertake a phenotypic, molecular, and symbiotic characterization of the ...

Identification of acetic acid bacteria by RFLP of PCR-amplified 16S rDNA and 16S-23S rDNA intergenic spacer. [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2000
DNA corresponding to 16S rDNA and the 165-23S rDNA intergenic spacer (ITS) from 22 reference strains of acetic acid bacteria, representing the diversity of the family Acetobacteraceae, and 24 indigenous acetic acid bacteria isolated from wine fermentations were analysed by PCR-RFLP.

Comparison of clinical metagenomics with 16S rDNA Sanger sequencing for the bacteriological diagnosis of culture-negative samples

International Journal of Medical Microbiology
Background: Currently, diagnosis of bacterial infections is based on culture, possibly followed by the amplification and sequencing (Sanger method) of the 16S rDNA - encoding gene when cultures are negative. Clinical metagenomics (CMg), i.e.

DNA sequence evidence for speciation, paraphyly and a Mesozoic dispersal of cancellothyridid articulate brachiopods [PDF]

, 2002
Because the classification of extant and fossil articulate brachiopods is based largely upon shell characters observable in fossils, it identifies morphotaxa whose biological status can, in practice, best be inferred from estimates of genetic divergence.

16S rDNA sequence variations of some Streptococcus suis serotypes [PDF]

International Journal of Systematic Bacteriology, 1998
Streptococcus suis 16S rDNA from selected serotypes has been sequenced and compared with the 16S rDNA sequences from serotypes 1 and 2 present in Genbank. After alignment the sequenced serotypes show clusters of variation. Based on these clusters, a limited phylogenetic tree showing the relationships of all of the serotypes was constructed.
