Abstract
Whereas yeasts were not normally isolated from raw semen samples, 13% of commercial frozen semen samples and 71% of preputial washings contained yeasts. Nine genera and 25 species of yeasts were identified from these 2 sources. Yeasts originating in the preputial cavity were generally saprobic members of the genera Candida, Cryptococcus, Rhodotorula, Saccharomyces, Torulopsis and Trichosporon. Those originating as contaminants during processing were more likely to be opportunistic pathogens of the genus Candida. Conception was not necessarily affected by the presence of large numbers of Candida krusei or C. macedoniensis in the uterus.
