[Combined viral-mycoplasma placentitis].
265 placentas were studied by means of light and fluorescent microscopy. 82 placentas showed combined infections induced by 2-5 agents (various viruses and mycoplasmas). Bacterial and fungal placentitis were excluded Manifestations depended on the infectious agents, their number and variants of their combination. Enhancement of vascular damage was observed in placentitis with participation of myxoviruses and herpes simplex virus. Enhancement of lymphoplasmacytic infiltration and sclerosis was typical for combined placentitis as well as alteration of antibody formation and interferon production. This reflects the gravity of the infection and its spread to the extra-placental membranes.
