Tween und Ather in mindestens zwei nichtinfektiose Untereinheiten zerlegen, die als Hamagglutinin und RNP-Antigen bezeichnet werden. Beide Viruskomponenten wurden isoliert und eingehender charakterisiert. \u00003Neben dem Virion werden bei der Vermehrung des NDV zumindest drei Arten von nichtinfektiosen Einheiten gebildet, namlich ein losliches Antigen sowie zellgebundene (ZGHA) und freie (FHA) hamagglutinierende Teilchen. Das losliche Antigen ist ein Ribonukleoproteid und entspricht dem RNP-Antigen des Virion. Die ZGHA scheinen Bestandteile des Ergastoplasmas der Wirtszelle zu sein, die mit Virus-Hamagglutinin beladen sind. Fur sie wird in Analogie zu den entsprechenden, bei Influenza vorkommenden Einheiten die Bezeichnung „Viromikrosomen” vorgeschlagen. Bei den FHA handelt es sich um Virus-Mis-bildungen, die keine RNS-haltige Innenkomponente (RNP-Antigen) besitzen. Sie gleichen in ihrem Aufbau und in ihren biologischen Eigenschaften weitgehend den Inkompletten Virusteilchen der Influenza und werden daher wie diese als „Inkomplette Formen” bezeichnet. \u00004Auf Grund der Untersuchungsergebnisse ist es berechtigt, die Myxogruppe in mindestens zwei Untergruppen (Influenza- und Multiforme Viren) zu unterteilen.

The soluble antigen is a ribonucleoprotein and represents the RNP antigen of the virion. The ZGHA represents portions of the ergastoplasm of the host cell laden with virus haemagglutinin. In analogy with similar bodies in influenza, the title viromicrosome is suggested. The FHA are abnormal virus particles which contain no RNA in their components (RNP-antigen).
