Abstract
The revised antigenic structure of the genus Candida which was divided separately into thermostable and thermolabile antigers was pustulated by the present authors through the antigen analysis with the seven standard strains.
The antigenic structure, however, will not serve as the basis of the species classification of the genus, unless antigenic structures of the many isolated strains would coincide with that of the standard strains.
In the experiment antigenic structures of twenty strains of every four species such as C. albicans, C. tropicalis, C. krusei and C. parakrusei, which had been selected at random among stock cultures, as well as a few strains of the other three species were proved to fit completely into the antigenic structure by means of slide agglutination tests with the monospecific antisera prepared on the antigenic structure. Consequently it will be concluded that the antigenic structure serves as the reliable basis of classification for the genus.
