Acyclovir-resistant HSV. Studies included untreated patients and patients who had been treated with the antiviral, except in reference 17, where the data are from treated patients only.
Viral susceptibility to acyclovir was measured by the plaque reduction assay.
Isolates from 915 subjects were tested for susceptibility to penciclovir by the plaque reduction assay. One was resistant to penciclovir.
Isolates from 1,004 subjects were tested for susceptibility to penciclovir by the plaque reduction assay. None was resistant to penciclovir.
