Bordetella

I always (somewhat foolishly, in retrospect) assumed that bordetella, also known as kennel cough, was named that because that's the environment where dogs tend to contract it.  When they're boarded, right?

Yeah, I know.  It's actually named after Jules Bordet, a Belgian microbiologist.  And strictly speaking, it's not even the name of the disease-- it's actually the genus of bacteria containing one of the culprits that cause kennel cough.  So I was wrong in all sorts of clever ways.  Huzzah!
