Tularemia is a serious infectious disease caused by the intracellular bacterium Francisella tularensis. It is also known as Pahvant Valley plague, rabbit fever, deer fly fever, and Ohara's fever.
In the 1950s, thousands of people were infected each year. This number has dropped considerably, to less than 200 each year, and those who are infected now tend to be those who are exposed to the organism in its rural habitat.
The drug of choice for tularemia treatment has historically been streptomycin or tetracycline-class drugs such as doxycycline. Gentamicin may also be used as it is easier to obtain than streptomycin.
The National Institutes of Health is funding several research projects to develop an effective vaccine against F. tularensis.
