Vaccine efficacy of a lysine auxotroph of Mycobacterium tuberculosis

Infect Immun. 2003 Jul;71(7):4190-2. doi: 10.1128/IAI.71.7.4190-4192.2003.

Abstract

The in vivo growth phenotype and vaccine efficacy of a lysine auxotrophic mutant of Mycobacterium tuberculosis strain H37Rv are described. An immunization experiment using a mouse model with an aerosol challenge showed that two doses of the M. tuberculosis mutant were required to generate protection equivalent to that of the Mycobacterium bovis BCG vaccine.
