Abstract
Four strains of herpes simplex virus (HSV) were isolated from 2 patients with recurrent herpes keratitis who failed to respond to 5-iodo-2''-deoxyuridine (IDU) treatment. Of the 4 isolates, 2 were highly resistant to IDU in [African green monkey kidney] cell culture and the other 2 isolates were more susceptible to IDU than an HSV-1 laboratory strain. From each patient, an IDU-resistant and an IDU-susceptible virus was isolated. All 4 isolates were able to induce thymidine kinase (TK) activity in cell lines lacking that activity. All isolates were type 1 HSV, since the filamentous structures, recognized as a biological marker of type 2 HSV, were not observed in infected cells.
