Summary

Infections with cytomegalovirus are common in all parts of the world. The virus may persist for many years in presence of high serum-antibody levels and infections may be transmitted by antibody-carriers. The proportion of antibody-carriers varies between 40% in advanced countries and 100% in some developing countries.

CMV is a member of the herpes-group. Virus-propagation is inhibited in vitro by substances like Flox-uridine, but no convincing results have as yet been obtained in clinical trials.

The diagnosis by virus isolation and antibody-demonstration is a reliable and reproducible method; it is more sensitive than the demonstration of inclusion bodies by cytological methods.

Zusammenfassung

Die Cytomegalie ist über die ganze Welt verbreitet. Das Virus persistiert nach der Infektion trotz hoher Serumantikörpertiter und die Antikörperträger sind potentielle Infektionsquellen. Die Durchseuchung der Bevölkerung ist regional unterschiedlich und schwankt zwischen 40% in den Industrieländern und 100% in den Entwicklungsländern.

Das Virus gehört in die Herpesgruppe. Die Virusvermehrung wird in vitro durch Brom- und Jod-desoxyuridin (Floxuridine) gehemmt, ohne daß diese Substanzen für die klinische Therapie zu überzeugenden Resultaten geführt haben.

Die virologische Diagnose durch Erreger- und Antikörpernachweis ist wesentlich empfindlicher und spezifischer als das cytologisch/histologische Nachweisverfahren.
