Biological Weapons 

Tularemia (also known as "rabbit fever") is a infectious disease caused by the bacterium Francisella tularensis. The disease is endemic in North America, and parts of Europe and Asia. The primary vectors are ticks and deer flies, but can also be spread through other arthropods. Rodents, rabbits, hares and ticks often serve as reservoir hosts. The disease is named after Tulare County, California.

Biological warfare, also known as germ warfare, is the use of any organism (bacteria, virus or other disease-causing organism) or toxin found in nature, as a weapon of war. It is meant to incapacitate or kill an adversary.
