Abstract

|
Yeast strains were isolated from healthy women(36 isolates), infertile women(15 isolates) and women suffering from local morbidity(82 isolates). On the basis of 37 different physiological and morphological characteristics, the isolated 133 yeast strains were assigned to 10 species belonging to 5 genera. Four pathogenic species were identified. They were Candida albicans, Candida parapsilosis, Candida tropicalis and Trichosporon beigelii. Candida albicans was the dominant species, whereas Saccharomyces cerevisiae provailed among the saprophytic species. The percentage occurrence as well as the pattern of yeast species differed in the diagnostic groups. It was higher in the women suffering from local morbidity than in the healthy and infertile women. Moreover, a wider spectrum of species was isolated from this group. Women with intrauterine contraceptive devices showed the highest percentage of yeast occurrence which reached 50% of those tested. Five different antifungal agents were tested fro their effects on the growth of the isolated yeast species in vitro. Nystatin was the most effective against the isolated yeast species, followed by pyrithion zink and ciclopiroxolamine, whereas micronazole and clotrimazole, showed a lesser effect.
