Saccharomyces cerevisiae vaginitis: microbiology and in vitro antifungal susceptibility.

Genitourinary infections by Saccharomyces cerevisiae are rare. Here, we describe eight S. cerevisiae vulvovaginitis episodes where molecular (Affirm VPIII) and conventional microbiological methods (culture and carbohydrate assimilation) have proven to be inadequate for diagnostic purposes. DNA sequencing allowed the correct identification of the pathogen. All isolates were susceptible to most antifungal agents, with two of them also found to be susceptible-dose-dependent to itraconazole.
