Abstract
Sixty-three strains of yeasts were isolated from vaginal contents of pregnant women and gynecological patients. They were not identified only by the morphological and biochemical examinations, but also by the slide agglutination tests using monospecific antisera, were made on the basis of their antigenic structures. Most of the yeasts isolated were Candida albicans (30), Torulopsis glabrata (13) and Candida guilliermondii (9). One strain of Candida robusta, one strain of Hansenula anomala and three strains of Debaryomyces kloeckeri were also isolated from the specimens. Furthermore, the relationships among the yeasts and ages, pregnancies, periodical seasons etc. were discussed.
