Host lifestyle affects human microbiota on daily timescales

Fascinating! Abstract: Disturbance to human microbiota may underlie several pathologies. Yet, we lack a comprehensive understanding of how lifestyle affects the dynamics of human-associated microbial communities. Here, we link over 10,000 longitudinal measurements of human wellness and action to the … Continue reading

The gut microbiota of insects

link Abstract Insect guts present distinctive environments for microbial colonization, and bacteria in the gut potentially provide many beneficial services to their hosts. Insects display a wide range in degree of dependence on gut bacteria for basic functions. Most insect … Continue reading

Effects of Antibiotics on Bacterial Species Composition and Metabolic Activities in Chemostats Containing Defined Populations of Human Gut Microorganisms

The composition and metabolic activities of the human colonic microbiota are modulated by a number of external factors, including diet and antibiotic therapy. Changes in the structure and metabolism of the gut microbiota may have long term consequences for host … Continue reading

Sex Differences in the Gut Microbiome Drive Hormone-Dependent Regulation of Autoimmunity

Abstract: Microbial exposures and sex hormones exert potent effects on autoimmune diseases, many of which are more prevalent in women. We demonstrate that early-life microbial exposures determine sex hormone levels and modify progression to autoimmunity in the nonobese diabetic (NOD) … Continue reading

Host-Derived Nitrate Boosts Growth of E. coli in the Inflamed Gut

Abstract: Changes in the microbial community structure are observed in individuals with intestinal inflammatory disorders. These changes are often characterized by a depletion of obligate anaerobic bacteria, whereas the relative abundance of facultative anaerobic Enterobacteriaceae increases. The mechanisms by which … Continue reading
