The following study determined whether commonly available mouse strains could be used to reveal vaccines capable of protecting against aerosol exposure to virulent type A strains of Francisella tularensis. The attenuated live vaccine strain (LVS) of the pathogen, E tularensis LVS, was used as the model vaccine for these studies. The results showed that most mouse strains survived intradermal immunization with 10(5) cfu of LVS, except for A/J mice the majority of which died following exposure to 10(4) cfu (colony forming units). Most LVS-immunized mouse strains survived subsequent i.d. challenge with >50LD(50) of a virulent type A strain of the pathogen. However, all mouse strains tested remained susceptible to lethal infection by a low dose (similar to20 cfu) aerosol challenge with virulent F tularensis even after vaccination with LVS, though immunized C3H/HeN mice appeared to be slightly more resistant than the rest to such an assault.
