Francisella tularensis is a small, aerobic, nonmotile gram-negative bacterium first identified in 1911 by Dr. Edward Francis, after an outbreak of plague-like disease in rodents in Tulare County, California. Infection has been reported in humans since 1914. In the United States, nearly all human cases of tularemia are caused by the F tularensis subspecies tularensis (type A, 66%) or F tularensis subspecies holarctica (type B, 34%).
