Microbial strain-level population structure and genetic diversity from metagenomes
Truong DT, et al. Genome Res 2017. PMID 28167665 Free PMC article.
We further estimated the genetic variability of gut microbes, with Bacteroides species appearing remarkably consistent (0.45% median number of nucleotide variants between strains), whereas P. copri was among the most plastic gut colonizers. ...

[Award Lecture]
[No authors listed] Nihon Saikingaku Zasshi 2017 - Review. PMID 28239041 Japanese. Free article.
Identifying genetic determinants needed to establish a human gut symbiont in its habitat
Goodman AL, et al. Cell Host Microbe 2009. PMID 19748469 Free PMC article.
We used massively parallel sequencing to monitor the relative abundance of tens of thousands of transposon mutants of a saccharolytic human gut bacterium, Bacteroides thetaiotaomicron, as they established themselves in wild-type and immunodeficient gnotobiotic mice, in the presence or absence of other human gut commensals. ...

Brain Structure and Response to Emotional Stimuli as Related to Gut Microbial Profiles in Healthy Women
Tillisch K, et al. Psychosom Med 2017. PMID 28661940 Free PMC article.
RESULTS: Two bacterial genus-based clusters were identified, one with greater Bacteroides abundance (n = 33) and one with greater Prevotella abundance (n = 7). ...For gray matter, the Bacteroides cluster showed greater prominence in the cerebellum, frontal regions, and the hippocampus. CONCLUSIONS: These results support the concept of brain-gut-microbiota interactions in healthy humans. ...

Alpha- and beta-mannan utilization by marine Bacteroidetes.
Chen J, et al. Environ Microbiol 2018. PMID 30246424
In Bacteroidetes genomes CAZyme encoding genes are mostly grouped in distinct regions termed polysaccharide utilization loci (PULs). ...We investigated four marine Bacteroidetes isolated from the southern North Sea that harbour putative mannan-specific PULs. These PULs are similarly organized as PULs in human gut Bacteroides that digest α- and β-mannans from yeasts and plants respectively. ...

Insights into the biodiversity of the gut microbiota of broiler chickens
Mancabelli L, et al. Environ Microbiol 2016. PMID 27129897
Comparison of the gut microbiota of chickens used for large-scale commercial production (Broiler Chicken, BC) and those grown in semi-wild conditions (Free-Range Chicken, FRC) revealed that at phylum level Firmicutes was the dominant phylum of the gut community in BC, while the gut microbiota of FRC contained higher levels of Bacteroidetes and Proteobacteria. ...

Shift of microbial composition of peri-implantitis-associated oral biofilm as revealed by 16S rRNA gene cloning
Al-Ahmad A, et al. J Med Microbiol 2018. PMID 29458668
RESULTS: Differing distributions of taxa belonging to the phyla Firmicutes, Bacteroidetes, Fusobacteria, Actinobacteria, Proteobacteria, Synergistetes, Spirochaetae and TM 7 were detected in both the healthy implant (HI) and the peri-implantitis (PI) groups. A significantly higher relative abundance of phylum Bacteroidetes, as well as of the species Fusobacterium nucleatum, were found in the PI group (P<0.05). ...

Polysaccharide Utilization Loci: Fueling Microbial Communities
Grondin JM, et al. J Bacteriol 2017 - Review. PMID 28138099 Free PMC article.
In Bacteroidetes bacteria, these systems are organized as polysaccharide utilization loci (PULs), which are strictly regulated, colocalized gene clusters that encode enzyme and protein ensembles required for the saccharification of complex carbohydrates. ...
