The Long-Term Stability of the Human Gut Microbiota

TLDR
Low-error sequencing data suggest that initial microbial colonizers of infant guts could persist over the life span of an individual, and members of Bacteroidetes and Actinobacteria are significantly more stable components than the population average.
Abstract
A low-error 16S ribosomal RNA amplicon sequencing method, in combination with whole-genome sequencing of >500 cultured isolates, was used to characterize bacterial strain composition in the fecal microbiota of 37 U.S. adults sampled for up to 5 years. Microbiota stability followed a power-law function, which when extrapolated suggests that most strains in an individual are residents for decades. Shared strains were recovered from family members but not from unrelated individuals. Sampling of individuals who consumed a monotonous liquid diet for up to 32 weeks indicated that changes in strain composition were better predicted by changes in weight than by differences in sampling interval. This combination of stability and responsiveness to physiologic change confirms the potential of the gut microbiota as a diagnostic tool and therapeutic target.

Proteobacteria: Microbial signature of dysbiosis in gut microbiota

TL;DR: This work reviews studies that explored the association between an abnormal expansion of Proteobacteria and a compromised ability to maintain a balanced gut microbial community and proposes that an increased prevalence of ProTeobacteria is a potential diagnostic signature of dysbiosis and risk of disease.

Gut biogeography of the bacterial microbiota

TL;DR: Novel hypotheses for how nutrient selection, immune activation and other mechanisms control the biogeography of bacteria in the gut are considered, and the relevance of this spatial heterogeneity to health and disease is discussed.

The ecology of the microbiome: Networks, competition, and stability

TL;DR: This finding indicates that hosts can benefit from microbial competition when this competition dampens cooperative networks and increases stability, and indicates that stability is promoted by limiting positive feedbacks and weakening ecological interactions.

Search and clustering orders of magnitude faster than BLAST

Robert C. Edgar
- 01 Oct 2010 - 
TL;DR: UCLUST is a new clustering method that exploits USEARCH to assign sequences to clusters and offers several advantages over the widely used program CD-HIT, including higher speed, lower memory use, improved sensitivity, clustering at lower identities and classification of much larger datasets.

Naïve Bayesian Classifier for Rapid Assignment of rRNA Sequences into the New Bacterial Taxonomy

TL;DR: The RDP Classifier can rapidly and accurately classify bacterial 16S rRNA sequences into the new higher-order taxonomy proposed in Bergey's Taxonomic Outline of the Prokaryotes, and the majority of the classification errors appear to be due to anomalies in the current taxonomies.

FLASH: Fast Length Adjustment of Short Reads to Improve Genome Assemblies

TL;DR: FLASH is a fast computational tool to extend the length of short reads by overlapping paired-end reads from fragment libraries that are sufficiently short and when FLASH was used to extend reads prior to assembly, the resulting assemblies had substantially greater N50 lengths for both contigs and scaffolds.
