Abstract
There are serological cross reactions among many species of the genera Candida and Torulopsis. Five species of the genus Torulopsis were obtained for antigen analysis. The experiments were carried out through the slide agglutination method using monospecific or absorbed antisera homologous to the antigens of the genus Candida. Antigenic structures of the species were confirmed by the absorption method. The new thermostable antigens were found in T. anomala, T. versatilis, T. magnoliae and T. sphaerica. Antigenic structrures of the five species were shown as follows : T. anomala and T. versatilis has the thermostable antigens 1, 10, 28, 31, 32 and 35, and no thermolabile antigen. T. sphaerica has the thermostable antigens 1, 10, 14, 28, 30 and no thermolabile antigen. T. magnoliae has antigen 35 besides the antigens of T. sphaerica. T. dattila has the thermostable antigens 1, 10, 18, 28, 31, 32 and no thermolabile antigen.
