Today’s digest has quite a few papers in the human oral and gut microbiome with many interesting papers as the one from M. Lepczyńska addressing positive aspects of various diets on gut microbiota and its fight with parasites. In ‘Water microbiome’ you can take a look at Raquel S. Peixoto’s paper and beneficial microbes maintaining coral health, while in ‘Microbes in News’ you can read how team from Korea is tackling one of medicine’s most pressing problems – antibiotic resistance by using bacteria to fight bacteria.
