Abstrakt: We have cloned and characterized the entire DNA polymerase gene and flanking regions from Kaposi's sarcoma-associated herpesvirus (KSHV) and two closely related macaque homologs of KSHV, retroperitoneal fibromatosis-associated herpesvirus-Macaca nemestrina(RFHVMn) and -Macaca mulatta(RFHVMm). We have also identified and partially characterized the corresponding genomic region of another KSHV-like herpesvirus, provisionally named “M. nemestrinarhadinovirus type 2 (MneRV-2),” with close similarity to rhesus rhadinovirus (RRV). A sequence comparison of these four macaque viruses and two KSHV-like gammaherpesviruses recently identified in African green monkeys, Chlorocebus rhadinovirus types 1 and 2 (ChRV-1 and ChRV-2) reveals the presence of two distinct lineages of KSHV-like rhadinoviruses in Old World primates. The first rhadinovirus lineage consists of KSHV and its closely related homologs RFHVMn, RFHVMm, and ChRV-1, while the second more distantly related lineage consists of RRV, MneRV-2, and ChRV-2. Our findings raise the possibility of the existence of another human KSHV-like herpesvirus belonging to the second rhadinovirus lineage.
