I think this actually happened:
A man came to the [University of Pittsburgh] clinic with a chronic infection in his left ear. He told doctors that other doctors had tried everything: anti-fungal drops, antibiotics, and many other treatments. The Pittsburgh doctors gave him additional antibiotics. The patient came back to the clinic a week later and said he was cured. The clinic doctors told him they were glad they had helped him. He said: “You didn’t. I suffered so much after your drugs I took some earwax from my right ear and put it in my diseased left. In two days I was fine, infection cured.” . . . The good ear contained good bacteria that killed off the bad in the bad ear.
I predict that people will eventually realize that the 2005 Nobel Prize for “ulcers are caused by bacteria” was a big mistake.
