title: Replication of herpes simplex virus in two cell systems derived from rhesus monkeys.
abstract: The replication of herpes simplex virus (HSV) in two cell systems derived from rhesus monkeys (LLC-MK2 and DBS-FRhL-2) was studied. In LLC-MK2, the growth of HSV-1 was abortive or extremely limited regardless of the multiplicity of infection, while that of HSV-2 was productive only on infection at high multiplicities. DBS-FRhL-2 cells supported growth of both types of HSV, although growth was highly dependent on the age of monolayers and the infectious dose of virus inocula. Plaques were produced in DBS-FRhL-2 cell monolayers inoculated with HSV-2 but not with HSV-1, although the efficiency of their formation in the former system was much less than in a system of FL and HSV-2. On the other hand, plaques were not produced in LLC-MK2 cell monolayers by either type of HSV. The growth of adapted variants of HSV-1 was also studied. In contrast to the parental strain, these variants replicated well in LLC-MK2 even at a low multiplicity of infection and produced clear plaques in the monolayers. Furthermore, persistent infections of HSV-2 were established in DBS-FRhL-2 cell monolayers under routine culture conditions.
