  1. Pyocyanase

    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. Emmerich and Löw isolated germs from infected bandages that caused green infections in open wounds. The germ was a bacterium then called Bacillus pycyaneus. They then mixed the isolate with other bacteria and showed that B. pycyaneus and extracts from its cultures were able to destroy other strains of bacteria. Among the bacteria that it killed were those that caused cholera, typhoid, diphtheria, and anthrax. From these experiments Emmerich and Löw created a medication based on extracts of B. pycyaneus that they called pyocyanase. It was the first antibiotic to be used in hospitals. Unfortunately, its effectiveness was sporadic, did not work equally on all patients, and the presence of large amounts of phenazines such as pyocyanin made it quite toxic to humans. As a result, the drug was eventually abandoned.
