The pathogenicity of herpes simplex virus type 1 (HSV-1) was investigated in mice of different ages, using virus isolates that differed in the level of thymidine kinase (TK) activity. The TK+ isolate from wild type virus was pathogenic in mice aged four to 28 days when inoculated onto scarified corneas. A mutant strain (designated TK1/4) that had 25% of the TK activity of the TK+ isolate was pathogenic for mice up to 10 days of age but was less pathogenic in older mice than the TK+ virus. The TK- virus with no TK activity killed mice that were four to seven days old, but mice older than 10 days survived. Infant mice with an undifferentiated nervous system are thus susceptible to the TK- virus which replicates in the neurons. Latent virus could be isolated from the ganglia of adult mice infected with the TK+ and TK1/4 virus strains but not with the TK- virus. The TK genes of the TK+ and TK1/4 virus strains were cloned in plasrnid pBR322 and the degree of expression of these genes was investigated. A sequence of 800 bp upstream to the BglII-BamHI 2800 bp fragment containing the viral TK gene was found to affect the expression of this gene in the TK1/4 virus strain.
