The guinea pig (gp) model of congenital cytomegalovirus (CMV) infection was used to evaluate a gpCMV glycoprotein vaccine. Hartley guinea pigs were immunized 3 times with 50 microg of lectin column-purified glycoproteins prepared from gpCMV-infected or -uninfected tissue culture. Immunization with the gpCMV vaccine produced seroconversion in all animals. Animals then were placed with gpCMV-seronegative male animals and were challenged late in pregnancy with virulent salivary gland-passaged gpCMV. Immunization with gpCMV glycoproteins significantly improved pregnancy outcome, with 54 of 63 pups live-born in immunized animals, compared with 21 of 48 in the controls (P<.001). In addition, virus was isolated from 24 of 54 live-born pups born to immunized mothers, compared with 16 of 20 live-born pups born to controls, indicating that immunization significantly reduced in utero transmission in surviving animals (P<.01).

D003587 Cytomegalovirus A genus of the family HERPESVIRIDAE, subfamily BETAHERPESVIRINAE, infecting the salivary glands, liver, spleen, lungs, eyes, and other organs, in which they produce characteristically enlarged cells with intranuclear inclusions. Infection with Cytomegalovirus is also seen as an opportunistic infection in AIDS.
