Abstract

After serial passage in the presence of increasing concentrations of ganciclovir (GCV) , a human herpesvirus-6 (HHV-6) mutant exhibiting a decreased sensitivity to the drug was isolated. Analysis of drug susceptibility showed that the IC of this mutant was 24-, 52- and 3-fold higher than that of the wild-type (wt) IC in the case of GCV, cidofovir and foscarnet, respectively. Genotypic analysis showed two single nucleotide changes as compared to the wild-type: an A→G substitution of the U69 protein kinase (PK) gene resulted in an MV amino acid substitution and the other change, located in the C-terminal part of the U38 gene, resulted in an AV amino acid substitution within the DNA polymerase. The MV change was located within the consensus sequence DISPMN of the putative catalytic domain VI of the PK. This change was homologous to the MV and MI changes that had been reported previously within the consensus sequence DITPMN of the human cytomegalovirus (HCMV) UL97 PK and associated with the resistance of HCMV to GCV. The MV change was also detected by PCR in HHV-6-infected PBMCs from an AIDS patient who had been treated with GCV for a long period of time and exhibited a clinically GCV-resistant HCMV infection. These findings provide strong circumstantial evidence that the MV change of the PK gene is associated with resistance to GCV and raise the question of cross resistance to this drug among different betaherpesviruses.
