A comparison of differenct extracts of Candida albicans in agar gel double diffusion techniques.

A preliminary comparative study, by 4 independent groups, of certain extracts of Candida albicans, showed variation in their antigenicity. Different agar gel double diffusion tests were used by each group; two groups used micro-methods and two used macro-methods. The number of positive precipitin reactions detected by these methods was shown to vary greatly.
