Relationship between phosphate content and serological activities of the mannans of Candida albicans strains NIH A-207, NIH B-792, and J-1012.
The mannans from Candida albicans strains NIH A-207 (serotype A), NIH B-792 (serotype B), and J-1012 (serotype C) were fractionated on a column of diethylaminoethyl-Sephadex into five subfractions containing different amounts of phosphate. Antibody-precipitating activities of the mannan subfractions of strains NIH A-207 and NIH B-792 were proportional to their phosphate content, while those of strain J-1012 did not show regularly proportional precipitin activity. A similar tendency was also observed in the cross-reaction between the mannan su,fractions of strains NIH A-207 and J-1012 and their heterologous antisera. The mannans of strain NIH B-792 showed lower cross-reactivities against antisera of strains NIH A-207 and NIH B-792, i.e., only two subfractions containing larger amounts of phosphate were able to react with these antisera.
