[The antigenic relationships between Hanseniaspora osmophila, H. uvarum and H. valbyensis strains].

The agglutinating sera against Hanseniaspora osmophila. H. uvarum and H. valbyensis agglutinated the homologous and heterologous Hanseiaspora strains. Cross agglutination and absorption tests showed that there was a common antigenic factor (s) among these three Hanseniaspora species. On the other hand, the tests have shown that the antigenic structures of H. uvarum and H. valbyensis are so much alike that they seem almost identical.
