Live vaccine strain of Francisella tularensis: infection and immunity in mice.
The live vaccine strain (LVS) of Francisella tularensis caused lethal disease in several mouse strains. Lethality depended upon the dose and route of inoculation. The lethal dose for 50% of the mice (LD50) in four of six mouse strains (A/J, BALB/cHSD, C3H/HeNHSD, and SWR/J) given an intraperitoneal (i.p.) inoculation was less than 10 CFU. For the other two strains tested, C3H/HeJ and C57BL/6J, ...
متن کاملThe immune response against Francisella tularensis live vaccine strain in Lps(n) and Lps(d) mice.
The impact of Lps gene on the course of immune response against subcutaneous infection of mice with Francisella tularensis live vaccine strain was studied. Production and specificity of antibodies, cytotoxic responses of macrophages and NK-cells, spontaneous production ex vivo of cytokines IL-1 alpha, IL-2, IL-4, IL-6, IL-10, IFN-gamma, and TNF-alpha in spleen cell cultures in C3H/HeJ (Lps(d)) ...
متن کاملBiology of Francisella tularensis Subspecies holarctica Live Vaccine Strain in the Tick Vector Dermacentor variabilis
BACKGROUND The γ-proteobacterium Francisella tularensis is the etiologic agent of seasonal tick-transmitted tularemia epizootics in rodents and rabbits and of incidental infections in humans. The biology of F. tularensis in its tick vectors has not been fully described, particularly with respect to its quanta and duration of colonization, tissue dissemination, and transovarial transmission. A s...
متن کاملTranscriptome analysis of human immune responses following live vaccine strain (LVS) Francisella tularensis vaccination.
The live vaccine strain (LVS) of Francisella tularensis is the only vaccine against tularemia available for humans, yet its mechanism of protection remains unclear. We probed human immunological responses to LVS vaccination with transcriptome analysis using PBMC samples from volunteers at time points pre- and post-vaccination. Gene modulation was highly uniform across all time points, implying ...
متن کاملPotential source of Francisella tularensis live vaccine strain attenuation determined by genome comparison.
Francisella tularensis is a bacterial pathogen that causes the zoonotic disease tularemia and is important to biodefense. Currently, the only vaccine known to confer protection against tularemia is a specific live vaccine strain (designated LVS) derived from a virulent isolate of Francisella tularensis subsp. holarctica. The origin and source of attenuation of this strain are not known. To assi...
