   Human gut Bacteroides capture vitamin B₁₂ via cell surface-exposed lipoproteins

   Aaron G Wexler et al.

   The human gut bacterial lipoprotein BtuG binds vitamin B12 with femtomolar affinity, can remove vitamin B12 from human intrinsic factor, and is required for commensal fitness in the gut.
2. 1. Ecology

   Experimental evaluation of the importance of colonization history in early-life gut microbiota assembly

   Inés Martínez et al.

   Experiments in ex-germ-free mice establish a measurable effect of colonization history on gut microbiota assembly, illuminating a potential cause for the high levels of unexplained individuality in host-associated microbial communities.
3. 1. Microbiology and Infectious Disease

   Changes in the genetic requirements for microbial interactions with increasing community complexity

   Manon Morin et al.
4. 1. Microbiology and Infectious Disease

   Resilience of small intestinal beneficial bacteria to the toxicity of soybean oil fatty acids

   Sara C Di Rienzi et al.

   Comparisons between lactobacilli bacteria in the small intestine and those evolved in the lab reveal several modes of resistance to toxic fatty acids.
5. 1. Computational and Systems Biology
   2. Immunology and Inflammation

   Computer-guided design of optimal microbial consortia for immune system modulation

   Richard R Stein et al.

   A computational method is presented that quantifies the effect that specific bacteria in the gut have on the immune system and guides the design of therapeutically potent microbial consortia to cure auto-immune disease.
6. 1. Microbiology and Infectious Disease

   Discovery and characterization of a prevalent human gut bacterial enzyme sufficient for the inactivation of a family of plant toxins

   Nitzan Koppel et al.

   A unique, widely distributed gut bacterial enzyme selectively metabolizes plant-derived cardiac glycoside drugs.

   2. Microbiology and Infectious Disease

   Social interaction-induced activation of RNA splicing in the amygdala of microbiome-deficient mice

   Roman M Stilling et al.

   Social-interaction impairment in germ-free mice is associated with a markedly altered transcriptional response to social novelty in the amygdala, as characterised by replacement of upregulation of common stimulus-induced pathways with upregulation of the splicing machinery.
8. 1. Microbiology and Infectious Disease

   Antibiotic-induced changes in the microbiota disrupt redox dynamics in the gut

   Aspen T Reese et al.

   Disturbing the microbiota with antibiotics alters gut redox state via changes in electron acceptor availability, setting the stage for post-antibiotic succession.

   2. Microbiology and Infectious Disease

   A selective gut bacterial bile salt hydrolase alters host metabolism

   Lina Yao et al.

   The deletion of a single gene encoding a selective bile salt hydrolase from the abundant human gut bacterium Bacteroides thetaiotaomicron significantly alters host metabolism.

    Antibiotic-induced acceleration of type 1 diabetes alters maturation of innate intestinal immunity

    Xue-Song Zhang et al.

    Alteration of host gut microbiota by antibiotic exposure in early life remodeled host intestinal immune development and metabolism and enhanced the induction of type 1 diabetes in genetically predisposed animals.
