Serologic analysis of the extractable carbohydrate antigens of Pityrosporum ovale.

Antigens soluble in hot trichloracetic acid from eighteen strains of Pityrosporum ovale were studied using rabbit antiserum to American Type Culture Collection strains 24027, 12078, and 14521. These strains were found to share two antigens, both of which were present in cells of Pityrosporum orbiculare and one of which was present in cells of Pityrosporum pachydermatis, Pityrosporum canus, Candida albicans and Rhodotorula rubrum.
