Abstract
The virological study of some influenza outbreaks recorded in Romania in the period Jnauary--March 1975 resulted in the isolation of 29 influenza A2 virus strains antigenically close to the strains A2/Port Chalmers 1/73 and A2/England 42/72. The non-homogeneous antigenic structure of the isolates suggests the possible formation of natural hybrids.
