title: Oligonucleotide fingerprint analyses of influenza C virion RNA recovered from five different isolates.
abstract: Five different isolates of influenza C virus which were isolated over a period of 32 years and from four different continents were compared by RNA genome oligonucleotide fingerprinting analyses. The earliest isolate of influenza C virus was reported in 1949 by Taylor (19) and served as a reference strain for this study. The results obtained using this technique of comparing relatedness between viruses clearly showed that all strains are distinct. However, the similarities in the pattern of the oligonucleotide fingerprints are marked for the more recent virus isolates (1966-1979), whereas the reference strain C/Taylor shows more pronounced differences. The results are consistent with the high degree of serological crossreaction amongst influenza C viruses isolated over a long period of time, a property which sets this group of viruses apart from type A and B members of the orthomyxoviridae.
