Analysis of specific interactions influenza virus and cells of different sensitivity. Note 2. Characteristics of influenza virus-host cell interaction in persistent infection.

Molecular hybridization was used for the demonstration of virus-specific RNA synthesis in the latent phase of influenza virus replication in the sensitive MDCK cell cultures and for its investigation in the persistent system represented by nonpermissive AO cells and influenza A/Victoria 35/72 (H3N2).
