PG - 2751-8 AB - The in vitro susceptibility of several nonhuman primate species to human herpesvirus 6 (HHV-6) was investigated. Only peripheral blood mononuclear cells from chimpanzees (Pan troglodytes) were found permissive to productive infection by HHV-6, indicating that the host range of HHV-6, albeit limited, may not be restricted to Homo sapiens. However, natural HHV-6 infection in chimpanzees, as well as in the other species tested, could not be documented by serological analysis. As previously observed with human cells, HHV-6 infection of chimpanzee peripheral blood mononuclear cells was highly cytopathic and the infected cells exhibited phenotypic features of activated T lymphocytes. Although in humans the majority of HHV-6-infected lymphocytes displayed the CD4 antigen, in chimpanzees a mixed CD4+ and CD8+ phenotype was observed. HHV-6 was also shown to productively coinfect individual chimpanzee T cells with human immunodeficiency virus type 1, resulting in an accelerated induction of cytopathicity. In light of these findings, we propose the utilization of chimpanzees as a potential animal model system to investigate the in vivo interaction between HHV-6 and human immunodeficiency virus type 1 and its relevance to the development of acquired immune deficiency syndrome.
