RESUMO
The genetics of innate resistance of mice to hepatitis induced by herpes simplex virus type 2 (HSV-2) was analyzed by crossing resistant male GR to susceptible female BALB/c mice and backcrossing females of this F1 generation to susceptible male BALB/c mice. By scoring of macroscopic liver lesions and virus isolation studies from the liver 4 days after intraperitoneal inoculation of HSV-2, it appeared that the resistance was governed by one X-linked dominant gene or closely linked gene complex, as F1 female mice were resistant and F1 male mice were susceptible and the trait segregated in a ratio close to 1:1 in the backcross mating. A cellular expression in vitro of virus resistance was found in the macrophage population of the mice as measured by differences in the restriction of HSV-2 replication in macrophage cultures prepared from individual mice. In contrast to what was seen in macrophage cultures, virus replicated equally well in embryonic fibroblast cultures from susceptible and resistant strains of mice.
