Samples collected in Mammoth Cave, Kentucky, revealed the presence of a psychrophilic yeast, tentatively identified as a strain of Candida albicans. The yeast is saprophytic on dead animal tissues and exhibits a pale yellow colour when growing in the cave. In vitro, the yeast grows poorly at 37°C. and well at 130 and 200, but loses its pigmentation. It is non-pathogenic in rabbits but appears to show low-grade parasitism in frogs.
