Antigenic Variation Among Type A Influenza Viruses,he hallmark of influenza virus is its variability, having the capacity to change its antigenic identity so remarkably that the specific immunity established in response to infection by a particular strain may give little or no protection against viruses that subsequently arise. Antigenic variation i

Expression of Cloned Influenza Virus Genes,nted expansion of our knowledge about the proteins of the virus. Analysis of the DNA sequence of the cloned genes, added to the information available from earlier classical protein chemistry studies, has led to the elucidation of the amino acid sequences of all the known virus-coded proteins and to

Influenza B and Influenza C Viruses,viruses classified as influenza type A have cross-reacting internal components, the matrix and nucleocapsid proteins. Influenza B and C viruses are similar in morphology (Fig. 1) and composition, and in their replication processes, to influenza A viruses. However no antigenic cross reactivity among

Molecular Epidemiology of Influenza Virus,to determine similarities among strains and to identify differences in viral variants. Most important among these techniques are cloning and sequencing of nucleic acids, RNA fingerprinting, peptide mapping and antigenic analysis of proteins with monoclonal antibodies. The purpose of this review, the
