Susceptibility of marmosets to Epstein-Barr virus-like baboon herpesviruses.

Epstein-Barr virus (EBV)-like herpeviruses, strains of Herpesvirus papio (HVP), have recently been isolated from lymphomatous (HVP-L) and from normal baboons (HVP-N). Both HVP isolates infect some species of marmosets, HVP-L inoculated adult animals develop a mild to severe and sometimes fatal lymphoproliferative disease whereas newborn marmosets of the same species do not develop a measureable disease after inoculation with HVP-l. HVP-N infects adult marmosets but does not cause disease.
