Saccharomyces cerevisiae vaginitis: transmission from yeast used in baking.
OBJECTIVE
To determine whether vaginitis due to Saccharomyces cerevisiae can be caused by exposure to exogenous sources of baker's yeast.


METHODS
Eight women with S cerevisiae vaginitis were identified from a cohort of women referred for the evaluation of chronic vaginal symptoms. In those with high-level exposure to exogenous sources of S cerevisiae, isolates from the vagina and those sources were sent in a blinded fashion for contour-clamped homogeneous electric-field electrophoresis.


RESULTS
Four women from a cohort of approximately 750 referred patients had high-level exposures to S cerevisiae. In one of these patients, electrophoresis analysis revealed similarities between the strains isolated from her vagina, her husband's fingers, and the yeast he used in his pizza shop.


CONCLUSIONS
Saccharomyces cerevisiae vaginitis can be the result of the inoculation of this yeast from exogenous sources.
