Background/aim: This study aimed to investigate the correlation between the prevalence of problematic pathogens and the clinical status of women with bacterial vaginosis (BV). Materials and methods: Gardnerella vaginalis, Atopobium vaginae, and Mobiluncus spp. were detected using a multiplex PCR assay, and their role in the infection of Bulgarian women with clinically heterogeneous BV was evaluated. Results: The predominant BV-associated pathogen identified was G. vaginalis with an incidence of 98.39%, followed by A. vaginae (68.05%) and Mobiluncus spp. at 17.01%. The coexistence of A. vaginae and G. vaginalis was more common in women with discharge (in 72.04%) and in patients with chronic recurrent BV than among asymptomatic or newly diagnosed BV cases (P < 0.05). Mobiluncus spp. was detected mostly in coinfections, in association with Trichomonas vaginalis. The coinfections were predominantly related to recurrent BV and with complications (P < 0.05). Conclusion: This is the first study about the correlation between problematic pathogens and clinically heterogeneous BV in Bulgarian women. High frequency of infection with key BV-related pathogens was observed in childbearing women. The incidence was shown to often correlate with coexistent T. vaginalis, with severity of infection, and with complicated and recurrent BV after unsuccessful treatments. Screening should be considered in reproductive health programs.
