Herpesviral DNA was detected in 24/261 DNA samples that were extracted from whole blood of 13 wild animal species in South Africa. Herpesviral DNA was shown in 22 impalas (Aepyceros melampus) and 2 springboks (Antidorcas marsupialis). All of DNA sequences detected in impalas were identical, whereas two DNA sequences detected in springboks were different each other. These three sequences showed 44 to 72% homology to the corresponding gene of the Gammaherpesvirinae, indicating that these three viruses should be unrecognized novel gammaherpesviruses. The putative novel herpesviruses were tentatively designated as Aepyceros melampus (impala) herpesvirus 1 (ImHV-1), Antidorcas marsupialis (springbok) herpesviruses 1 (SpHV-1) and 2 (SpHV-2). ImHV-l seems to be a relatively independent virus. SpHV-1 belongs to a group of ruminant lymphotropic herpesviruses and SpHV-2 is closer to a malignant catarrhal fever virus group. Potential threat of these herpesviruses to domestic animals should be considered.
