THE PREVALENCE OF GARDENERELLA VAGINALIS IN PATIENTS WITH BACTERIAL AND NON-BACTERIAL VAGINOSIS ATTENDING TO GYNECOLOGY CLINIC OF IMAM HOSSEIN HOSPITAL, SPRING AND SUMMER 2016

Developing bacterial vaginosis is of high prevalence especially in pregnant
women. The most common causes of bacterial vaginosis are anaerobic microorganisms such as
Gardnerella vaginalis. The aim of this study was to determine the prevalence of Gardenerella vaginalis
isolated in women with bacterial and non-bacterial vaginosis.
Materials & Methods: The study was conducted on 500 women attending to Gynecology Clinic of
Imam Hossein Hospital. Demographic data of patients were studied. Based on Amsel criteria, vaginosis
was divided into bacterial and non-bacterial vaginosis groups. For diagnosis of Gardnerella vaginalis
isolates, the secretion was cultured in specific Colombia-Agar- medium under anaerobic conditions and
after gram staining, biochemical tests were performed. Molecular PCR method was used to identify
isolates. Data analysis was performed using SPSS software.
Results: Among 220 patients with vaginosis, 56.81% had bacterial and 43% had non bacterial vaginosis.
The prevalence of Gardenerella vaginalis was 21.8%. From these, 60.4% and 39.5% were from patients
with bacterial and non-bacterial vaginosis, respectively. There was a significant relationship between
age group and contraceptive method by IUD with bacterial vaginitis.
Conclusion: The High incidence of Gardenerella vaginalis in women with bacterial vaginosis confirms
the important role of bacteria in the occurrence of bacterial vaginosis. It is necessary for identification
of pathogenic agents responsible for bacterial vaginal infections using culture-based methods to
recommend the correct medical treatment in different societies
