[Hemagglutinating activity of Candida albicans culture extracts]

3M KC1 extracts of Candida albicans cultures display a haemoagglutinating activity on human and sheep red blood cells. The haemoagglutinins, may be lectins in nature, behave like antigens being fully inhibited by anti-Candida immune serum. The latter lyses human red blood cells sensitized with 3M KC1 Candida albicans extracts. Human and animal red blood cells react against Candida albicans hypertonic salt solution extracts, in double diffusion agar tests, and give one or more precipitation lines. The interpretation of the results is discussed.
