In vitro and in vivo replication of seal gammaherpesviruses in cells of multiple species.
Phocid herpesvirus virus type 2 (PhHV-2), a putative gammaherpesvirus of seals, has been isolated from harbor seals (Phoca vitulina) and grey seals (Halichoerus grypus). In the present study, different PhHV-2 isolates were shown to have a broad in vitro tropism for various cell types from several mammalian species. Inbred mice and two species of non-human primates proved to be susceptible to experimental infection with PhHV-2. The development of myoepitheliomas and spleen hyperplasia upon cyclosporin A treatment in some of the PhHV-2-infected animals warrants further investigation of the oncogenic and zoonotic potential of this virus.
