Aim: The aim of the current study was to investigate the frequency of development of bacterial vaginitis (BV) in women of reproductive age, aged 18 to 45 years old. Those women undertook a microbiological examination of vaginal secretion either in the context of preventive control or because of the appearance of clinical symptoms. Material and method: A microbiological test of vaginal secretion was done in 500 women of reproductive age, aged 18 to 45 years old. Those women came for examination, either in the context of preventive control or because they had disturbing symptoms in the genital area. The following factors were recorded: age, existence of clinical symptoms such as itching, burning, excessive vaginal secretion, pain, as well as history of vaginitis. During the sample intake, the presence of pathological secretion, rush or pain were recorded. The diagnosis of bacterial vaginitis was based on the Amsel’s criteria. Results: Out of the 500 women of reproductive age, BV was detected to 145 (29%) and 33% of them were asymptomatic. 86,2% of the women reported excessive smelly vaginal secretion. Furthermore, 95,8% of women were found with excessive vaginal secretion and last but not least in 73% of women, pain was detected. History of vaginitis was reported by the 83,3% of women with BV. Conclusion: It can be argued that BV was detected in a great number of women of reproductive age. The high percentages of asymptomatic women with BV, as well as the serious complications, and the fact that BV constitutes a predisposition factor for infection with HIV, impose the application of preventive laboratory control in order to avoid bacterial vaginitis.
