Initial characterization of a CPV-resistant HCMV isolate (2696r). HFF infected with the CPV-resistant HCMV isolate (dashed lines) were exposed to increasing concentrations of either CPV (■) or GCV (▲) and were compared to HFF infected with wild-type virus (solid lines) exposed to the same concentrations of drugs. Values are means ± standard deviations from at least two experiments. Asterisks indicate that the replication of 2696r is significantly different (P < 0.01) from that of the wild-type virus (with both drugs).
