ABSTRACT

Objective: To study the rates of lower genital tract infections (Candida spp., bacterial vaginosis (BV), Trichomonas vaginalis), during pregnancy. Material and methods: Two hundred and twenty three vaginal swab specimens from pregnant women who attended the Obstetrics Section at the Hospital of Clinics from August 1, 2005 to January 15, 2006, were prospectively and consecutively examined. The diagnosis of Candida spp. was made by microscopic wet smear examination with saline solution and potassium hydroxide at 10% and culture (Sabouraud agar and blood agar). The diagnosis of BV was made using the Nugent´s score (≥ 7) and the presence of three or more of the following criteria described by Amsel: presence of clue-cells in the microscopic examination, pH ≥ 4.5, fishy odor test positive and thin, homogeneous vaginal discharge. The investigation of T. vaginalis was made by direct wet mount with saline solution and with SAF/Methylene blue, Giemsa stain, solid medium culture (Modified Columbia agar) and liquid culture media (Modified Thioglycolate Medium). Results: We documented 22.4% of infections for Candida spp. by culture, 21.5% for bacterial vaginosis by Nugent´s score and by clinical criteria and 4.5% for Trichomonas vaginalis by culture, during pregnancy. Conclusions: The method used in this study diagnosed a rate of infections for Candida spp., bacterial vaginosis and Trichomonas vaginalis similar to another authors, during pregnancy. We suggest performing a microbiologic study of vaginal exudates during pregnancy whether clinical symptoms are present or not, in order to install an early and adequate treatment to present possible maternal and perinatal complications.
