Good morning! Today’s microbiome digest is brought to you by mild insomnia induced by a mid-afternoon coffee. It includes two food related studies, one on pathogenic E. coli found in ready-to-eat foods and the other focused on a antifungal lipopeptide produced by B. velezensis isolated from honey, and an an article focused on a new approach for processing frozen lung and lavage samples for use in microbiome studies. Also included are several articles focused on the gut microbiome, and several preprints focused on soil microbiome studies. Finally, I want to highlight a piece that details the positive outcomes associated with the National Summer Undergraduate Research Project (NSURP). Registration for this year’s program is still open until April 15th, and the organizers are looking for both mentors, mentees, and donors!

February 16, 2022

Happy Wednesday! Today’s digest includes two gut-brain axis papers from Sarkis Mazmanian’s lab at CalTech. The first article, published in Nature, found that 4-ethylphenol (4EPS) produced by gut microbes from dietary tyrosine was capable of entering the brain and changing gene expression, brain cell interactions, and brain functions. In the second study, published in Nature Medicine, oral administration of the adsorbent AB-2004–which can bind and sequester phenolic compounds–led to reduced levels of gut 4EPS and decreased anxiety in human adolescents with autism spectrum disorder.

I have also included an article published by my thesis lab in The Journal of Allergy and Clinical Immunology looking at the impact of seasons on the respiratory microbiome and asthma exacerbations in children.

Finally, there is an interesting paper by Baranova et al. in which the authors identify a bacterial species ubiquitous across multiple wild animals that appears to have novel functions for pathogen control or microbiome remodeling. Happy reading!
