Today’s digest is quite diverse: the respiratory microbiome networks in cystic fibrosis patients, ketogenic diet effects on the gut microbiota in children with severe epilepsy, and insect-associated Streptomyces (spoiler: inhibit antimicrobial-resistant pathogens more than soil Streptomyces). Happy reading!
