Have a good day! Greetings from Santiago, Chile.  Today, in this Digest: a set of papers about the microbiome-gut-brain axis, as well as a couple of studies about vaginal microbiota. We have also some articles about the microbiome of dogs and turtles, as well as a study about the relationship between microplastic and shrimp microbiota. Finally, we have also some articles about new tools for microbiome analysis, and best practices for developing microbiomics methods.

P.S.: As a member of the MD Team, I want to wish Dr. Bik and all the other members of the Team, a Happy New Year, hoping this 2021 could be much better than this challenging 2020. 

And, of course, thanks to everyone who visits us and share our posts! Happy New Year!
