Francisella Tularensis

 This species was found in ground squirrels in Tulare County, California, in 1911; Bacterium tularense was before long confined by George Walter McCoy (1876–1952) of the US Plague Lab in San Francisco and detailed in 1912. In 1922, Dr. Edward Francis (1872–1957), a doctor and clinical analyst from Ohio, found that Bacterium tularense was the causative specialist of tularemia, in the wake of considering a few instances of his patients having side effects of the said malady. Afterward, it got known as "Francisella tularensis", out of appreciation for the revelation by Dr. Francis. Four subspecies (biovars) of F. tularensis have been grouped.
