It’s likely that rotifers evolved this incredible trick more than a million years before Alexander Fleming dabbled with “mould juice” to stumble upon penicillin.

Dr. Endo said his career was also inspired by a biography he read of Alexander Fleming, the Scottish biologist who discovered penicillin in the 1920s.

Almost a century ago, the discovery of antibiotics like penicillin revolutionized medicine by harnessing the natural bacteria-killing abilities of microbes.
