What is the difference between bubonic and pneumonic plague?
It brings me memories of microbiology class. Bubonic plague produces a bubo, which is an inflammation of the lymph gland. If you have a swollen lymph gland (hey, what's that ball-size thing growing on my leg???) and you live in the New Jersey or New York area, then you might want to go to the hospital, not your doctor, immediately.
Oh, there was a little incident with some laboratory mice gone missing from a New Jersey lab yesterday.
Some fun reading about bubonic plague is provided here by National Geographic.
Fortunately, bubonic plague cannot be transmitted between humans. If you have rats, or pets that can acquire fleas, however...
