Effect of treatment with BB-94 on survival of mice with MM. BALB/c mice were infected i.c. with 106 cfu/mouse of strain 93/4286 (group C) of N. meningitidis, injected i.p. with either BB-94 (n = 21) or vehicle (n = 20), and sacrificed 48 h later. Treatment with BB-94 (50 mg/kg) was carried out 1 h before and 24 h post-infection. Data are represented as a Kaplan-Meier survival curve.
