title: [Nucleic acid molecular hybridization as a method for the laboratory diagnosis of influenza: its potentials and prospects].
abstract: Experiments carried out by the present moment in a number of laboratories indicate that the method of molecular hybridization (MH) has great diagnostic potential. Sufficient methodological mastery of the reaction of radioactively labeled DNA probes with RNA samples applied into a polymer membrane and good supply of commercially available materials make it possible to recommend this method for use in reference laboratories at specialized diagnostic centers. Hybridization should be used in combination with traditional virological and serological tests; the combined use of MH and the enzyme immunoassay for the determination of viral antigens permits the documentation of 90-98% of all cases of influenza A with sufficient rapidity. In the near future DNA probes for the diagnosis of influenza B and C are likely to appear. MH has rather good prospects for the analysis of experimental infection in laboratory animals, as well as for the study of the replication of influenza virus in all cultures. The prospects of the study of the processes of expression of individual genes seem to be particularly attractive. MH may play an important role as a tool for documenting vaccinal reaction, as well as for the study of the action of different chemical preparations in volunteers. And finally, the greatest expectations are linked with the use of MH for the search of inapparent (persistent, latent, etc.) forms of influenza virus infection both in experimental systems and in humans. Optimistic prospects of the studies in this field are based on high sensitivity of this method combined with its equally high specificity. An additional reserve for enhancing sensitivity is also present here due to the amplification of target molecules.
