The inoculation of Candida albicans into the web between the third and fourth fingers regularly induced the typical picture of erosio interdigitalis blastomycetica, provided the fingers were sealed together to provide complete occlusion. The aerobic flora increased enormously, but C albicans accounted for less than 1% of the total. A mixture of gram-negative rods became established in great numbers. It is proposed that erosio interdigitalis blastomycetica is a synergistic infection between a small quantity of C albicans and a much larger population of one or more gramnegative rods.
