Mycoplasma hominis in women with bacterial vaginosis.

An association between M. hominis and bacterial vaginosis (BV) was looked for in total 205 women characterized as having BV. Vaginal specimens from these patients were studied for the presence of amines, polymorphonuclear leukocytes, clue cells, and lactobacilli, and were also cultured to isolate Gardnerella vaginalis, M. hominis, Trichomonas vaginalis, Candida albicans and anaerobes. G. vaginalis was found to be the most common isolate from 132 cases (64.3%). M. hominis was isolated from 90 cases (43.9%). 62 per cent of M. hominis isolates were associated with G. vaginalis. 100 age matched control group revealed low prevalence of G. vaginalis and M. hominis whereas the difference in isolation rate of anaerobes was not significant. Anaerobes were found in association with M. hominis in 40 per cent cases. The treatment of these patients was decided after knowing the etiological agent.
