Francisella tularensis

Francisella tularensis is a pathogenic species of Gram-negative coccobacillus, an aerobic bacterium. It is nonspore-forming, nonmotile, and the causative agent of tularemia, the pneumonic form of which is often lethal without treatment. It is a fastidious, facultative intracellular bacterium, which requires cysteine for growth Tularemia is caused by the bacterium Francisella tularensis. The disease mainly affects rabbits, hares, and rodents, such as muskrats and squirrels. Tularemia can also infect birds, sheep and domestic animals, such as dogs, cats and hamsters Francisella tularensis is a gram-negative bacteria (Gram-negative bacteria contain an outer membrane outside the peptidoglycan cell wall, unlike Gram-positive bacteria that have a thicker layer of cell wall and no outer membrane. Many of the Gram-negative bacteria are pathogenic), with pili on the surface
