The aim of this study is the determination of the frequency of vaginal Candida colonization in pregnant women in the third trimester, the status of the vaginal ecosystem, the grade and the subspecies of the candidal colonization, clinical manifestations and the therapeutic effect of the local antimycotic treatment. In this study it has been followed 172 pregnant women with a normal pregnancy at the end of the third trimester. It has been estimated that about 28.4% of all women get a vaginal yeast colonization - Candida spp. In 89.7% (44 women) of the cases, the colonization was caused by an overgrowth of the yeast Candida albicans. The remaining cases are caused by other subspecies of Candida - 5 cases (10.3%) - C. tropicalis /2/, C. parapsilosis /2/, C. glabrata/1/. The women in the first group were with symptoms of active candidosis (25.6%) and 88.3% of the cases were confirmed by microscopy, and 90.6% after a bacterial growth in a culture. In 7.7% of the cases was specified a mild to moderate colonization without a clinical signs of infection (II group). The local treatment with antimycotic vaginal globules and crème for 5 to 7 days alleviates the clinical symptoms. It was not observed a case of maternal - fetal transmission of this infection not a clinical manifestation in the early postpartal period.
