Experts are sounding the alarm over antimicrobial resistant bacteria, commonly known as "superbugs." A report commissioned by the Public Health Agency of Canada warned that 40 per cent of bacterial infections will be resistant to treatment by 2050, and by that time the superbugs may have killed nearly half a million Canadians. The bugs develop when bacteria, viruses and fungi evolve to resist drugs, and unnecessary use of antimicrobials by humans can speed up the process. To help discuss these superbugs and what we can do to prevent their spread, John is joined by Dr. Joseph Blondeau, Clinical Microbiologist and Head of Clinical Microbiology at RUH and U of S.
