LVS vaccination does not protect C57BL/6 mice as well as BALB/c mice against i.n. NMFTA1 challenge. (A) Vaccinated and unvaccinated C57BL/6 mice (n = 4) were challenged i.n. with 2 × 102 CFU of NMFTA1 22 days after vaccination. (B) Survival rates of vaccinated C57BL/6 mice (n = 4) and vaccinated BALB/c mice (n = 5) after i.n. challenge with 2 × 102 CFU of NMFTA1. (C) Naïve, freshly vaccinated C57BL/6 mice and vaccinated C57BL/6 mice boosted with 5 × 104 CFU of LVS (five to six per group) were challenged i.n. with 2 × 102 CFU of NMFTA1.
