Za0Using the PCR method for detection of bacterial vaginosis in women suspected of vaginosis in Guilan province

Introduction: Bacterial vaginosis is the most common lower genital tract infection among women in reproductive age. Its causative agent is often the bacterium Gardnerella vaginalis which exists in synergism with other mostly anaerobic bacteria such as Atopobium vaginae, Mobiluncus curtisii and Megasphaera type I. The present study was conducted with aim of measuring molecular measurements (PCR) in the detection and diagnosis of bacterial vaginosis in women. Methods: This descriptive study was performed on 100 women referred to Obstetrics and Gynecology Clinics of Al-Zahra Hospital and private clinics in Rasht from September 2016 to October 2017. They were examined and tested for bacterial vaginosis. The presence of Gardnerella vaginalis was tested by five different laboratory methods based on Amsel criteria and molecular methods including determination of appearance characteristics, determination of pH, Whiff test, and observation of Clue cells in direct smear, conducting Polymerase Chain Reaction (PCR) using specific primers on DNA extracted from vaginal specimens. Data were analyzed using SPSS software (version 21) and Chi-square test. P<0.05 was considered significant. Results: In this study, from a total of 100 suspected women who were examined for vaginal infection with use of Amsel method, 31 cases (31) of vaginosis were confirmed. Using the molecular method of PCR in women with vaginosis (Amsel method), Gardnerella vaginosis was confirmed in 14 (45) and Atopobioum vagine in 10 (32). Conclusion: Using the PCR method showed that Gardenerella vaginalis and Atopobium vaginae play an important role in womenaged 18-35-year-old with bacterialvaginosis that indicates the role of these two bacteria in the development of bacterial vaginosis.
