[Ultrastructural pathology of the placenta in respiratory-syncytial viral infection and mycoplasmosis]. / Ul'trastrukturnaia patologiia platsenty pri respiratorno-sintsitial'noi virusnoi infektsii i mikoplazmoze.

Electron microscopy of the placentas affected by respiratory-syncytial virus and mycoplasmas (Mycoplasma urealyticum) revealed the most pronounced alterations in the syncytiotrophoblast structures. Destructive changes in the respiratory-syncytial infection were associated with a direct reproduction of viral particles. Two types of alterations (acute and long-lasting) reflecting two stages of the infectious process are reported in the Mycoplasma infection.
