In baboon gut microbiota, most pairwise correlations in bacterial abundances are weak and negative, and bacterial correlation patterns are largely shared across hosts, rather than personalized to each hosts.

Gut microbial signatures of domestication parallel those of industrialization, implicating shared ecological drivers.

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

The density of the gut microbiota influences the host immune system and adiposity, and can be therapeutically manipulated.

Urban wildlife harbor gut bacteria found in humans but missing from rural wildlife, consistent with bacterial transmission from humans to wildlife in cities.

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.

Social interactions can have a direct effect on the composition of the gut microbiome in wild primates.

A multi-cohort analysis of 2,500 gut microbiomes and five major diseases discovers that disease-microbiome associations display specific age-centric trends, with diseases characterized by age-centric trends of species gain/loss.

The gut microbiota of East Asians is distinct, dissociated from body mass, and self-sustains compared to White subjects from the same region, and therein may underpin a key health disparity.

Recurrent neural network models enable prediction and design of health-relevant metabolite dynamics in synthetic human gut communities.
