Differences in permissive cytomegalovirus infection between primary cultured human fetal membrane chorion and amnion cells.

Human cytomegalovirus (CMV) is the most common cause of viral intrauterine infection in developed countries. It has been shown that CMV DNA was frequently detected in the fetal membranes when the placenta was infected in utero. However, it is still not clear whether CMV replicates in constituent cells of the fetal membranes.
