What is recurrent bacterial vaginosis? Recurrent bacterial vaginosis is an imbalance of the vaginal bacteria normally present in the vagina. Bacterial vaginosis is a common condition and treatment is available; however, in some women the condition may recur or even become chronic, requiring multiple and sometimes long-term treatments.
Approximately 90% of all cases of vaginitis are thought to be attributable to 3 causes: bacterial vaginosis, vaginal candidiasis (or vulvovaginal candidiasis [VVC]), and Trichomonas vaginalis infection (trichomoniasis). Bacterial vaginosis is the most common cause of vaginitis, accounting for 50% of cases. As previously mentioned, bacterial vaginosis is caused by an overgrowth of organisms such as Gardnerella vaginalis (a gram-variable coccobacillus), Mobiluncus species, Mycoplasma hominis, and Peptostreptococcus species.
