Study of host antigens in the envelopes of different myxo- and paramyxoviruses cultivated in the embryonated hen egg.

By immunoelectrophoretic analysis it was shown that different viruses--such as myxo- (influenza A0PR8) and paramyxoviruses (Sendai, SV5, NDV, mumps)--cultivated in the same host cells (chorioallantoic membranes) incorporate similar host antigens into their envelopes. The amount of host cell antigens incorporated into the virus envelopes differs from one virus to another. The fact that incorporation of host cell antigens occurs only after a virus-induced modification seems to be a general characteristic of enveloped viruses such as myxo- and paramyxoviruses.
