About this episode
The episode discusses how dog ownership during adolescence affects microbiota and mental health, along with the molecular mechanisms of multidrug efflux.
TWiM explains the finding that owning a dog during adolescence alters the microbiota and improves mental health, and the molecular basis for multidrug efflux by an anaerobic-associated resistance-nodulation-cell division transporter.
