Evaluation of the antigen specific to the mycelial phase of Candida albicans in the serodiagnosis of candidiasis.

We demonstrated 2 different antibodies against Candida albicans in patients' sera, the detection rates were proportional to the severity of candidiasis. One antibody was directed toward antigen shared by Candida in both blastospore and mycelial phases and the other was directed against antigen found only in the mycelial phase of Candida. The presence of the latter may reflect the invasive form of candidiasis.
