title: [Hemagglutinin specificity of Cl. botulinum types A, B, and F in reaction with erythrocytes of various animals].
abstract: The following differences were revealed in the haemagglutination reaction with the erythrocytes of man, sheep, rabbit, chicks and mice between the haemagglutinins of Cl. botulinum, types A, B and F, having a close affinity with one another: haemagglutinin of type A actively reacted with the erythrocytes of man, sheep, rabbit, rats and chicks; haemagglutinin of type B reacted only with the erythrocytes of man and rabbits; haemagglutinin of type F failed to react with any of the types of the erythrocytes tested; only with the use of erythrocytes treated with neuraminidase was it possible to establish the presence of haemagglutinin fraction in Cl. botulinum, type F. Treatment of human erythrocytes with neuraminidase and proteolytic enzymes caused a marked increase in the sensitivity of the haemagglutination reaction in haemagglutinins of Cl. botulinum, types A, B and F.
