Survival chart showing percentage survival in days post-inoculation (p.i) for groups of five mice inoculated either intracranially (IC) or intramuscularly (IM) with neat IKOV (10^4.8 TCID₅₀ ml⁻¹) or a 1/10 dilution (10^3.8 TCID₅₀ ml⁻¹). Mice not clinically affected after 11 days were still healthy when euthanized at 28 days and negative for lyssavirus antigens post-mortem.
