Abstract: | The nature of the cross reaction of the mycelial mannan of Trichophyton rubrum and galactomannan isolated from the culture medium of Aspergillus fumigatus with antisera of Saccharomyces cerevisiae and Candida albicans is described. Cross-reactivity of polysaccharides of both T. rubrum and A. fumigatus was weak with antisera of C. albicans and S. cerevisiae, but the galactomannan of A. fumigatus showed slightly stronger activity than the mannan of T. rubrum which possesses more closely related chemical structure of the mannans of S. cerevisiae and C. albicans. |
