A Francisella tularensis Live Vaccine Strain (LVS) Mutant with a Deletion in capB , Encoding a Putative Capsular Biosynthesis Protein, Is Significantly More Attenuated than LVS yet Induces Potent Protective Immunity in Mice against F. tularensis Challenge

Abstract excerpt

Francisella tularensis, the causative agent of tularemia, is in the top category (category A) of potential agents of bioterrorism. The F. tularensis live vaccine strain (LVS) is the only vaccine currently available to protect against tularemia; however, this unlicensed vaccine is relatively toxic and provides incomplete protection against aerosolized F. tularensis, the most dangerous mode of transmission. Hence,...
