The purpose of this study was to identified nonessential murine cytomegalovirus (MCMV) genes involved in pathogenesis in vivo. Our approach to identifyjng these genes consisted of constructing MCMV mutants, and then analyzing these mutants in vitro and in vivo. Recombinant viruses (RV) expressing the β-glucuronidase marker gene were constructed by site-directed insertion and deletion mutagenesis of the MCMV Hind III-J and -I regions of the viral genome. Mutations were targeted to this region of the MCMV genome because the corresponding region of the human CMV genome is nonessential and is involved in down-regulating major histocompatibility complex (MHC) class I expression …
