You know what I'm talking about. The Plague.
It's caused more human deaths than any other infectious disease, save for malaria and tuberculosis.[1]
It's caused by the bacteria Yersinia pestis, a gram-negative, rod-shaped bacterium.
It's primary host is the rat, and the intermediate hosts between rats and humans are fleas. (Guess that gives me another reason to lay down rat/mouse traps.)
Since it primarily infects rats, but sometimes infects humans as well, it is a zoonotic disease. (disease which primarily infects animals, although it can also cause disease in humans)
Infected rats generally die soon after infection, but the survivors develop a chronic condition in which the animal can keep transferring the disease to other organisms.[1]
