Regulation of tight junction permeability by intestinal bacteria and dietary components by Ulluwishewa, Dulantha, Anderson, R., McNabb, W., Moughan, P., Wells, J., Roy, N.

“…The intestinal barrier is a complex environment exposed to many dietary components and many commensal bacteria. Studies have shown that the intestinal bacteria target various intracellular pathways, change the expression and distribution of TJ proteins, and thereby regulate intestinal barrier function. …”

T Follicular Helper Cells Promote a Beneficial Gut Ecosystem for Host Metabolic Homeostasis by Sensing Microbiota-Derived Extracellular ATP by Perruzza, L., Gargari, G., Proietti, M., Fosso, B., D'Erchia, A., Faliti, C., Rezzonico-Jost, T., Scribano, D., Mauri, L., Colombo, D., Pellegrini, G., Moregola, A., Mooser, C., Pesole, G., Nicoletti, M., Norata, Giuseppe, Geuking, M., McCoy, K., Guglielmetti, S., Grassi, F.

“…© 2017 The Authors The ATP-gated ionotropic P2X7 receptor regulates T follicular helper (Tfh) cell abundance in the Peyer's patches (PPs) of the small intestine; deletion of P2rx7, encoding for P2X7, in Tfh cells results in enhanced IgA secretion and binding to commensal bacteria. Here, we show that Tfh cell activity is important for generating a diverse bacterial community in the gut and that sensing of microbiota-derived extracellular ATP via P2X7 promotes the generation of a proficient gut ecosystem for metabolic homeostasis. …”

Bacterial antimicrobial metal ion resistance by Hobman, Jon L., Crossman, L.C.

“…As the use of antimicrobial metals is limited, it is legitimate to ask: are antimicrobial metal resistances in pathogenic and commensal bacteria important now? This review details the new, rediscovered and 'never went away' uses of antimicrobial metals; examines the prevalence and linkage of antimicrobial metal resistance genes to other antimicrobial resistance genes; and examines the evidence for horizontal transfer of these genes between bacteria. …”

Antimicrobials and antimicrobial resistance: two studies investigating different ways to tackle the issue by Osborne, Nicola C.

“…The aim of the project was to improve the gastric retention and reduce the exposure of commensal bacteria to antimicrobial drugs. This should reduce side effects and allow a lower concentration of drug to be administered. …”

Early life determinants of wheeze and allergic disease: a longitudinal study in an Ethiopian birth cohort by Amberbir, Alemayehu

“…However, none of these commensal bacteria were associated significantly with either incidence or prevalence of allergic outcomes. …”

Isolation and Characterisation of Microbial DNA from Rain Tree Barks by Mun, Chee Onn

“…Most microorganisms present in nature are uncultivable by standard techniques and functions of commensal bacteria remained largely uncovered. Metagenomics assessment to study microbial community on tree barks was not attempted from literature search. …”

Nonselective bottlenecks control the divergence and diversification of phase-variable bacterial populations by Aidley, Jack B., Rajopadhye, Shweta, Akinyemi, Nwanekka, Lango-Scholey, Lea, Jones, Michael A., Bayliss, Christopher D.

“…Phase variation occurs in many pathogenic and commensal bacteria and is a major generator of genetic variability. …”

Opportunistic bacteria confer the ability to ferment prebiotic starch in the adult cystic fibrosis gut by Wang, Y., Leong, L.E.X., Keating, R.L., Kanno, T., Abell, G.C.J., Mobegi, Fredrick, Choo, J.M., Wesselingh, S.L., Mason, A.J., Burr, L.D., Rogers, G.B.

“…Supplementation with high amylose maize starch (HAMS) might provide clinical benefit by promoting commensal bacteria and the biosynthesis of immunomodulatory metabolites. …”

Anthropogenic environmental drivers of antimicrobial resistance in wildlife by Swift, Benjamin M.C., Bennett, Malcolm, Waller, Katie, Dodd, Christine, Murray, Annie, Gomes, Rachel L., Humphreys, Bethan, Hobman, Jon L., Jones, Michael A., Whitlock, Sophia E., Mitchell, Lucy J., Lennon, Rosie J., Arnold, Kathryn E.

“…We conclude that AMR in commensal bacteria of wildlife is not driven simply by anthropogenic factors, and, in practical terms, this may limit the utility of wildlife as sentinels of spatial variation in the transmission of environmental AMR.…”

Genomic insights to control the emergence of vancomycin-resistant enterococci by Howden, B., Holt, K., Lam, M., Seeman, T., Ballard, S., Coombs, Geoffrey, Tong, S., Grayson, M., Johnson, P., Stinear, T.

“…Whole-genome sequencing was performed on 61 E. faecium (36 VREfm) isolates, predominately from blood cultures collected at a single hospital between 1998 and 2009, and on five vanB-positive anaerobic commensal bacteria isolated from human feces. Phylogenomic analysis and precise mapping of the vanB gene, which contains the Tn1549 transposon, showed that at least 18 of the 36 VREfm isolates had acquired the transposon via independent insertion events, indicating de novo generation of VREfm rather than cross-transmission. …”

Effects of dietary zinc oxide nanoparticles supplementation on broiler growth performance, zinc retention, liver health status, and gastrointestinal microbial load by Mohd Yusof, Hidayat, Abdul Rahman, Nor'Aini, Mohamad, Rosfarizan, Zaidan, Uswatun Hasanah, Arshad, Muhammad Aiman, Samsudin, Anjas Asmara

“…ZnO NPs at 100 mg kgˆ’1 in the diet showed antibacterial effects, reducing Enterococcus spp. and E. coli count significantly, without affecting commensal bacteria (lactic acid bacteria) count. Conclusion: The inclusion of ZnO NPs to broiler chicken feed as a Zn source had no negative effects on growth or health. …”
