Tularemia is caused by the bacterium Francisella tularensis. It is a disease that affects animals and humans. Rabbits, hares, and rodents are especially susceptible to the disease but it can affect a variety of mammals. Tularemia can be found throughout the United States. The bacteria can be spread by bites of fleas, ticks, and other arthropods.
