I 100% concur with Barak about our great Microbiome Digest, and we invite YOU to join us to create useful content for our community. Today’s Digest hopefully brings you much food for thought. I would draw your attention towards two papers about insecticide and antibiotic resistance. The first is about the mechanism for malaria transmitting mosquitoes to tolerate the common pesticide, pyrethroid. The second is on a potential genetic engineering approach to replacing antibiotic resistant plasmids with artificial ones. Of course, there are many more articles and news pieces to read from.

Today’s digest covers population based studies on regional specificity of the gut microbiome, guidelines on use of fecal microbiota transplant, and review articles on role of the gut microbiome in colorectal cancer, liver tumors and functional gastrointestinal disorders. Also includes articles on how xenobiotics and psychotropic drugs affect the gut microbiota, and link to wonderful bacterial art!
