title: Thymidine kinase-deficient herpes simplex virus type 2 genital infection in guinea pigs.
abstract: In guinea pigs, thymidine kinase-producing strains of herpes simplex virus type 2 replicated to high titer in the vagina and spinal cord, and animals developed severe clinical disease. Infection with thymidine kinase-deficient virus resulted in similar vaginal virus titers; however, animals exhibited little or no clinical illness and only low titers of virus were detected in spinal cord homogenate cultures. Neural and extraneural latent infection as well as recurrent infection were noted in animals inoculated with either thymidine kinase-producing or -deficient viruses. These data suggest that neural pathways are important in the pathogenesis of genital herpes and that virus-coded thymidine kinase may influence virulence but is not required for latency.
