title: [The antigenic characteristics of influenza A viral strains circulating synchronously in 2 separated areas (the CzSFR--Saint Petersburg)].
abstract: A comparative study of the antigenic characteristics of influenza A (H1N1) and A (H3N2) virus strains isolated during the same epidemic season, 1989-1990, in St. Petersburg and CzSFR was carried out by routine serological methods and by cross-challenge of immunized mice. Antigenic differences were found only among serosubtype A (H1N1) strains isolated in different areas. The study was carried out in connection with potential occurrence of influenza epidemic outbreaks from local sources.
