Pyocyanase was the first antibiotic drug to be used in hospitals. It is no longer used today. Rudolph Emmerich and Oscar Löw, two German physicians who were the first to make an effective medication from microbes, conducted experiments in the 1890s, roughly 30 years after Louis Pasteur showed that many diseases were caused by bacteria and nearly 40 years before the effective prescription of penicillin. They proved that the germs that caused one disease may be the cure for another.
