Latent Protocol: Kaplan Meier analysis of the fate of BALB/c scid (N = 70) and immunocompetent BALB/c (N = 30) ganglion recipients. Mice were observed daily for evidence of infection and death. The day of death was recorded as the number of days after grafting. One of the BALB/c scid mice died on day28, but virus was not found in the graft site or brain of this animal. There was no significant difference between the survival of the BALB/c scid and immunocompetent BALB/c mice (P > 0.05).
