Polymicrobial nature of vaginitis in young women: a microbiological and therapeutic study

Thirty-six young females attending the Student Health Service with vaginitis were investigated by serial semiquantitative aerobic, anaerobic, fungal, mycoplasma and viral cultures over a 10 day period and results were correlated with signs and symptoms. Antifungal therapy (econazole pessaries and cream) resulted in clearance of candida from 13 out of 16 patients where there was no increase in the anaerobic flora. In the four subjects where candida was isolated along with Gardnerella vaginalis plus abnormal anaerobic flora, only one cleared with econazole, the remaining three clearing during therapy with metronidazole. In the nine subjects with Gardnerella vaginalis and abnormal anaerobic flora, metronidazole relieved symptoms despite failure to eradicate G. vaginalis in seven indicating the pathogenic role of the anaerobic flora rather then G. vaginalis. Mycoplasma hominis, Ureaplasma urealyticum and gram negative enteric bacilli were not implicated as primary agents in causing vaginitis.
