Are HHV-6 and HHV-8 actually PLHV-1 and PLHV-2 Pigs?

"We recently reported the discovery of DNA sequences of two closely related gammaherpesviruses in pigs—the porcine lymphotropic herpesviruses 1 and 2 (PLHV-1 and -2). These viruses are widespread in domestic pigs and are closely related to several ruminant gammaherpesviruses, most of which are etiologically implicated in the occurrence of malignant catarrhal fever (MCF), a lymphoproliferative and inflammatory disease with an often fatal outcome. PLHV-1 and -2 are also related to EBV, HHV-8, and other gammaherpesviruses, but more distantly Ehlers et al 1999b and Ulrich et al 1999."
