Polysaccharide Protection: How Bacteroides thetaiotaomicron Survives an Antibiotic Attack

Microbial metabolism in the gut is important for host immunity, digestion, and the modification of drugs, but it may be especially important for gut health during antibiotic treatments. In this issue, Cabral et al. (2019) study the taxonomic and metabolic responses to antibiotics and identify a diet-modulated tolerance of Bacteroides thetaiotaomicron.
