Exciting work by @gdwantibiotics.bsky.social and team, with a new molecule that is toxic to bacteria - a promising new candidate for new antibiotics!

The last time a new class of antibiotics reached the market was nearly three decades ago — but that could soon change, thanks to a discovery by researchers at McMaster University.

In a new op-ed for @theconversationca.bsky.social, IIDR Director Matthew Miller writes that as "we stand on the brink of an avian influenza pandemic," lessons learned from COVID-19 can help us avert disaster — but only if we act on them. #IDSKy #H5N1 #BirdFlu

Heeding the lessons of COVID-19 in the face of avian influenza

COVID-19 exposed the many ways in which we were ill-prepared to prevent and respond to pandemics. Are we applying those lessons to prevent a bird flu pandemic?
