title: A murine gammaherpesvirus.
abstract: In 1976, within a project on isolation of herpesviruses from small rodents in former Czechoslovakia, the mouse herpesvirus strain 68 (MHV-68) was isolated (Blaskovic et al., 1980). This virus was accepted by The International Committee on Taxonomy of Viruses (ICTV) as a new, so far unassigned species (member) of the Gammaherpesvirinae subfamily of the Herpesviridae family (Murphy et al., 1995). Besides MHV-68, four more isolates (MHV-60, MHV-72, MHV-76, and MHV-78) similar to MHV-68 were obtained in that field experiment in Slovakia. Later, three more isolates (MHV-Sumava from Bohemia and MHV-4556 and MHV-5682 from Slovakia) were obtained in other field experiments. All these isolates are in some properties similar but in others different from each other. Nevertheless, as their comparative genome sequence analysis is not yet available, we propose at present to regard all the abovementioned isolates as different isolates of the same virus and strain, i.e. MHV-68. It is not excluded that a more detailed characterization of these isolates in the future will lead to proposals of designating some of these isolates as new strains of the virus of concern. This review summarizes the up to date knowledge of various biological and physico-chemical properties of MHV-68. At least three isolates, MHV-68, MHV-72 and MHV-Sumava seem to be involved in malignant neoplasm development in mice. It should be stressed that the pathogenesis of the induced lymphoproliferative disease in mice is similar to that caused by Epstein-Barr virus (EBV) in humans.
