Candida concentrations in the vagina and their association with signs and symptoms of vaginal candidosis

Abstract

Among 106 women harbouring yeasts in the vagina and with other causes of genital pathology excluded, there was a statistically significant association between numbers of yeasts recovered semi-quantitatively from vaginal swabs and symptoms of pruritus and signs of abnormal vaginal discharge but no association between yeast numbers and other individual symptoms or signs of vaginal candidosis, including patients' own subjective assessment of abnormal vaginal discharge. The presence of yeasts detectable by direct microscopic examination was statistically associated with pruritus, discharge and vaginitis. There was no relationship between numbers of vaginal yeasts and histories of antibiotic or oral contraceptive usage or the stage of the menstrual cycle. Distributions of Candida species and Candida albicans biotypes were not statistically related to any symptoms, signs or other factors. The results of this study suggest that vaginal pathology caused by Candida species may be related to the quantity of the fungus in the vagina and that only pruritus and objectively assessed vaginal discharge are firm clinical indicators of Candida infection.
