HERNANDEZ, Francisco. Gardnerella vaginalis Mobiluncus en la etiología de la vaginosis bacteriana . Rev. costarric. cienc. méd [online]. 1998, vol.19, n.1-2, pp.107-116. ISSN 0253-2948.

Vaginitis and bacterial vaginosis (BV) are the most frequent infections in women. The former is associated with specific agents, such as Candida, Trichomonas, and Chamydea.; nevertheless, there are a high frequency of cases without defined agent, that were considered in the past as "inespecific vaginitis". Actually the majority of those cases as defined BV, common and underdiagnosed syndrome, in which etiology are associated a poly-micorobial population from the altered vaginal flora. Two of the most important agents related with BV are Gardnerella vaginalis and Mobiluncus spp. The former was described in 1953 as the agent responsible of inespecific vaginitis; however, its prevalence in cases and controls was similar and inoculations in volunteers do not confirm its role in the vaginitis. Today, the quantitative analysis of bacterial populations, cytotoxin found in this agent confirms its role in the ethiology of BV. Mobiluncus is a toxigenic anaerobic agent related with VB and with other pathologist as choriomnionitis, preterm birth, post-abortal pelvic inflammatory disease and post-caesarean endometritis. This agent is anaerobic and fastidious; nevertheless, the Gram stein is the most common diagnosis tool for BV.
