ABSTRACT Guinea pigs sensitized with purified galactomannan from Aspergillus fumigatus and mannan from Candida albicans , each containing negligible quantities of nitrogen, were examined for their immunological responses against the corresponding polysaccharides with respect to the delayed‐type skin reaction and the macrophage migration inhibition phenomenon. In both cases, the delayed‐type skin reaction test and the macrophage migration inhibition test showed positive results. The reactivity was stronger in animals sensitized with polysaccharides in Freund's complete adjuvant than those sensitized with the same polysaccharides in Freund's incomplete adjuvant. Polysaccharides chemically modified by partial acid degradation or by periodate oxidation were found to be completely incapable of eliciting such immune responses. These results are also discussed in relation to the antigenic determinant of the polysaccharides in such immune responses and the precipitin reaction previously observed by us and other investigators.
