Abstract
The authentic strains of the five speciesl of the genus Hansenu'a were used for antigea anayses by means of slide agglutination method with monospecific or absorbed antisera homologous to antigens of the genus Candida. Antiserum of a species was absorbed repeatedly with heated cells of several species of the genus Candida in order to find a new antigen until the absorbed antiserum was exhausted. Antigenic structures of the species were confirmed by the reciprocal absorption method. H. subpelliculosa and H. silvicola have thermostable antigens 1, 2, 14, 15, 16 and 20 as does H. anomala, H. suaveolens and H. mrakii have antigens 1, 2, 14, 15, 16, 17, 20 and 21 as does H. saturnus, H. californica has antigens 1, 2, 14, 15, 16, 17, 10, 21 and 22. Every species does not have any thermolabile antigen.
