Today’s digest is short and sweet! We have articles on the gut microbiota in rats, the influence of host genetics on the leaf fungal microbiome, and biofilm fouling in drinking water. There are also two manuscripts which provide tips for pathway enrichment analysis and biomarker discovery.

Happy reading! Also, if you’re in Scotland, consider checking out the enormous E. coli in Edinburgh this weekend!
