Abstract

Among the , human cytomegalovirus is the only virus to possess simian homologues. Indeed, intriguingly, no close simian homologue of the roseoloviruses (HHV-6) and (HHV-7), the other two human members of the , has been identified to date. Here, the first simian homologue of HHV-6 is described, which was identified in common chimpanzees and designated PanHV6. By using a degenerate consensus PCR method, three different gene fragments were amplified, corresponding to the DNA polymerase (U38), -chemokine receptor (U12) and viral transactivator (U42) genes, with 94–96 % (nucleotide) and 95–97 % (amino acid) sequence identity to the corresponding genes of HHV-6B. Analysis of 77 predominantly wild-caught chimpanzees identified a unique PanHV6 strain in 21 animals, with no viral sequence variation between the different chimpanzee subspecies that were found to be infected. Characterization of this virus represents a great potential to gain a better understanding of the diseases associated with HHV-6.
