Today’s digest features a systematic assessment of best practices for the sequencing-based characterization of the human vaginal microbiome, studies on link between the plaque microbiome and peri-implantitis, cutimycin [a Cutibacterium acnes-produced antibiotic that affects niche competition among the human skin microbiota] and antibiotic resistance genes in shower drains, washing machines, and dishwashers. There is a new Micro Binfie Podcast episode about moving from the wet lab into the dry lab to become a bioinformatician. Also, check out a list of interesting (freely available) events. Happy reading/listening!
