Murid herpesvirus 4

Murid herpesvirus 4 (MuHV 4) is a virus in the genus Rhadinovirus. It is a member of the subfamily Gammaherpesvirinae in the family Herpesviridae. MuHV 4 infects mice via the nasal passages and causes an acute infectious mononucleosis-like syndrome with elevated levels of leukocytes, and shifts in the relative proportion of lymphocytes along with the appearance of atypical mononuclear cells. Murid herpesvirus 4 currently serves as a model for study of human gamma-herpesvirus pathogenesis.
