[Detection of varicella virus with a DNA probe in fetal blood and amniotic fluid].

In our Centre for Prenatal Diagnosis, we undertook a punctuation of the umbilical cord on a pregnant woman infected with varicella, complicated by viral encephalitis, to diagnose a foetal viraemia. In cooperation with the Toma Laboratory and Clonit Ltd., who have long been working on the development of specific viral genome probes, we succeeded in proving, that the foetus had contracted varicella.
