Abstract

This article accounts for the development of immunochemical studies on the antigenic polysaccharide, mannan, a major antigen of pathogenic yeast in man, genus Candida, in order to determine the chemical structures dominating the serological specificities of the parent cells as follows. 1. The serological classification system of 7 medically important Candida species by detecting 10 antigenic factors, 1, 4, 5, 6, 8, 9, 11, 13, 13b, and 34 the corresponding antisera, established by Tsuchiya and his coworkers is documented. 2. The structural studies of Candida mannans until early 1980s, which did not include any evidence for the presence of beta-1,2-linked Man unit, the common constituent of antigenic factors, 5, and 6, are also reviewed. 3. The process of structural identification of antigenic factor 5 residing in the mannans of C. albicans, C. tropicalis, and C. stellatoidea, in the phosphate-bound form of beta-1,2 linked mannooligosaccharides, is summarized. 4. The results of structural identification of antigenic factors 4 and 6 in the mannans of the acid-stable domains of C. albicans are summarized as follows: In order to isolate oligosaccharides containing beta-1,2 and alpha-1,6 linkages, a modified acetolysis method under m...Continue Reading
