Figure 4. Rescuing cell invasion by filamentous Δp60ΔNamA Lm is not sufficient for protective T cell memory development.
Titers of viable WT Lm CFU in the spleen and liver of mice immunized with 0.1×LD50 of indicated Lm, and challenged 5 weeks later with 3×105 WT Lm for 48 hrs. All experiments show representative data of 1 experiment; each symbol represents 1 mouse and histogram bars average mean values.
