Vaginal pH and microflora related to yeast infections and treatment.

Abstract
The relationship between vaginal pH, microflora and yeast infection was investigated in 93 women randomly treated with nystatin or miconazole pessaries and cream for 2 wk. Vaginal pH was measured in a control group of 48 women. In the study group 37 patients defaulted, 39 were cured and 17 required treatment during the 6-mo. follow-up period. In study and control groups before and after treatment the mean vaginal pH was 4.3-4.6. Lactobacilli were plentiful in 78 (91%) of 86 patients. Lactobacilli and yeasts commonly co-exist. The influence of other organisms appeared negligible. Nystatin and miconazole were equally effective in the treatment of vaginal yeast infection. The broad-spectrum activity of miconazole offered no advantage in this condition.
