Fran·ci·sel·la tu·la·ren·sis

a bacterial species that causes tularemia in humans, transmitted from wild animals by bloodsucking insects or by contact with infected animals (for example, ticks); main sources of infection are rabbits and ticks; it can penetrate unbroken skin to cause infection, and if inhaled can cause a rapidly fatal pneumonia; type species of the genus Francisella.

Francisella tularensis
biotype A (F. tularensis biovar tularensis) is the etiological agent of tularemia; biotype B (F. tularensis biovar holarctica (palaearctica)) is less virulent. Formerly called Pasteurella tularensis.
