“Background Bacteria in the Francisella genus are nonmotile, nonsporulating, gram-negative coccobacilli. Francisella causes a zoonotic disease; humans can become infected via a variety of mechanisms including inhalation of an extremely low infectious dose [1]. F. LDN-193189 datasheet tularensis primarily targets macrophages where bacterial survival and replication occurs [1]. The genus Francisella is divided into two species: tularensis and philomiragia. Francisella tularensis has four subspecies: PCI-32765 in vitro F. tularensis subspecies tularensis (formerly F. tularensis,) F. tularensis subspecies holarctica (which includes the live vaccine GBA3 strain, LVS), F. tularensis subspecies mediasiatica, and F. tularensis subspecies novicida (F. novicida) [2]. Subspecies of Francisella tularensis are further separated into two types depending on their virulence. Type A strains include Francisella tularensis subspecies tularensis Schu S4 (F. tularensis

Schu S4) and are more virulent [3], except for the ATCC type strain F. tularensis subsp. tularensis NIH B38 which is avirulent [4–6]. Francisella Type A strains are normally associated with ticks and rabbits and are restricted to North America. Type B strains (Francisella tularensis subspecies holarctica and mediasiatica) are less virulent and cause tularemia throughout Eurasia [3]. Standard recommended antibiotic treatment for tularemia includes oral tetracycline antibiotics (e.g. doxycycline) and fluoroquinolones (e.g. ciprofloxacin) which have adverse side-effects on pediatric and the elderly patients, and individuals with liver disease. Aminoglycosides such as streptomycin and gentamicin can be injected intravenously or intramuscularly [7], but are not commonly used. Macrolides are oral antibiotics commonly used to treat bacterial respiratory illnesses.
