Francisella

 [fran″sĭ-sel´ah]
a genus of gram-negative, aerobic, coccoid or rod-shaped bacteria; F. tularen´sis (formerly called Pasteurella tularensis) is the etiologic agent of tularemia.

Francisella

(fran-si-sel'lă),
A genus of nonmotile, non-spore-forming, aerobic bacteria that contain small, gram-negative cocci and rods. Capsules are rarely produced and the cells may show bipolar staining. These organisms are highly pleomorphic; they do not grow on plain agar or in liquid media without special enrichment; they are pathogenic and cause tularemia in humans. The type species is Francisella tularensis.

/Fran·ci·sel·la/ (fran″sĭ-sel´ah) a genus of microorganisms, including F. (Pasteurella) tularen´sis, the etiologic agent of tularemia.

Francisella

a genus of nonmotile nonspore-forming gram-negative aerobic bacteria that is a facultative intracellular pathogen of macrophages. Frequently found in natural waters, it can be parasitic in humans, other mammals, birds, and arthropods. The organism causes tularemia in humans.

Francisella

a genus of very small gram-negative bacteria.

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.
