About this episode

The episode discusses how nutrient competition affects drug side effects on gut microbiota and the role of metabolic control in porin permeability and antibiotic resistance.

TWiM explains how competition for nutrients anticipates and potentially mitigate drug side effects on the gut microbiota, and metabolic control of porin permeability influences antibiotic resistance.
