Greetings from Santiago, Chile! Today in this Digest, we have studies about the influence of alcohol use disorder on the microbiota, several papers about the influence of different compounds (from allicin to DAV132, a colon-targeted antibiotic adsorbent) on the microbiota. Today we have several papers about different models of plant- or soil- associated microbiomes, and a couple of papers from studies with SIV infection models. Have a nice weekend!
