Determination of types 1 and 2 hemagglutinins in serotypes of Hemophilus paragallinarum.
Type 1 hemagglutinin (HA) of Hemophilus paragallinarum (HPG) was found only in Page's serotypes A and B and in Kato's serotypes I and III of HPG. Type 2 HA was found in all serotypes of HPG. Hemagglutination-inhibition test revealed no serological differences among the type 2 HA of Kato's serotypes.
