The COVID-19 pandemic drove home an important lesson: that the smallest organisms can be the deadliest. Not only are they highly fatal, they are also incredibly adept at evading the antibiotics and antimicrobials that we have in our relatively pitiful arsenal of drugs. In conjunction with World Antimicrobial Awareness Week (18-24 November), Prof Stephen Baker, molecular microbiologist and Director of Research at the Department of Medicine, University of Cambridge, dials in to share his research on antimicrobial resistance, and how we can change the course of this global health threat.
