title: Comparative study on two methods for serotyping of Staphylococcus aureus: the Pillet method and the Oeding method. II.-Possible identity between Pillet's antigen 9 and Oeding's antigen h1.
abstract: Using two techniques (agglutination and immunoprecipitation), the authors have observed that: -Pillet's strain CK9 and Oeding's strains 670 and 17A are very similar; -antigen 9 is also present in the three strains; the same relation is found in wild strains. Using agglutination and immunoprecipitation, there is a cross reactivity between h1 factor serum, serum 9 and strains CK9, 670 and 17A. A precipitation line involving strain CK9 and serum CK9 is described in the Pillet system. Finally, there is a strong presumption that Oeding's h1 antigen and Pillet's antigen 9 are identical.
