Bckground: Aerobic vaginitis is an imbalance of the vaginal flora and the main characteristic is an abnormal vaginal flora that contains aerobic and intestinal pathogens with varying degrees of vaginal inflammation. The frequency of AV varies from 12% to 23.7% in symptomatic women who are not pregnant and 4 to 8% during pregnancy and has an increased risk for sexually transmitted diseases (STI). The causative agents of AV are: Enterococcus faecalis (E. faecalis), Esherichia coli, group B streptococcus and Staphylococcus aureus. Objective: The aim of this review was to present the most important features of aerobic vaginitis regarding description of this frequent clinical problems within population in Bosnia and Herzegovina and also worlfwide. Methods: Author analized aerobic vaginitis based on scientific literature by searching published papers in important indexed databases. Results and Discussion: The most frequently isolated AV pathogen is E. faecalis in about 31%. New works indicate the presence of the HPV 16 gene and genome in E. faecalis in the biopsied material of cervical cancer, as well as the ability that HPV 16 genes can be translated and transcribed in these bacteria, and that the HPV gene can form viral particles in these bacteria leads to certain connection that can be a risk factor in the progression of cervical lesions to cancer. A decrease in the number of lactobacilli in the vaginal secretion reduces the defense ability and changes the pH value of the vaginal environment, which favors the development of bacterial inflammation. AV positive for E. faecalis leads to a change in the pH value of the vaginal environment above 5, and the increased pH value of the vaginal environment in HPV positive women can be an association for cervical intraepithelial lesion (CIN). A dominant pathogen in AV such as E. faecalis can reduce the protective effect of lactobacilli by causing inflammation, as well as an increase in IL-6, IL-8 and TNF, increasing the risk of HPV 16 infection resulting in CIN and cervical cancer. In cervical cancer research, the presence of genes and genomes (except E1) of human papillomavirus (HPV) type 16 was found in bacteria such as: E. faecalis and Staphylococcus aureus from cervical cancer biopsies. Intensive treatment of AV could be a very important factor in preventing the onset of precancerous lesions and cervical cancer. The recommended treatment of AV includes a combination of therapy such as: antibacterial (antiseptic and antibiotic), hormonal, non-steroidal anti-inflammatory and/or probiotics, which can be prescribed in the form of local or systemic therapy. Conclusion: There is no generally accepted clinical strategy for the treatment of AV caused by E. faecalis. Most authors suggest that therapy be based on microscopic or microbiological findings using a topical antibiotic for the infectious agent, a topical steroid to reduce inflammation, and estrogen to treat atrophy.
