Possible role of different animal species in maintenance and spread of murine gammaherpesvirus 68 in the nature

摘要

Murine gammaherpesvirus 68 (MHV-68), isolated from a bank vole (Clethrionomys glareolus) in Slovakia in 1976 is a natural pathogen of wild murid rodents. This review is focused to biological properties of this pathogen, the mode of its maintenance in murid rodents as reservoir animals, mechanisms of its spread to other animals in the same biotope as well as to livestock and household animals. Potential role of ticks as vectors and the possibility of infection of humans with this virus are considered as well. All the above evidence of the virus infection of various hosts is based on serological or molecular analytical data. The presented knowledge indicates important epizootologic consequences, namely harboring and permanent maintenance of the virus in murid rodents as reservoir animals with a real possibility of spread to other animals in the same biotope. These relationships imply a cross-species virus transmission with potential serious consequences for the infected animals or humans.
