Question

The discharge is characteristic of Candida overgrowth. Note that no foul odor is mentioned, and the negative amine test "rules down" bacterial vaginosis and Trichomonas. Both yeast vaginitis and yeast diaper rash have the described satellite lesions outside the area of major erythema. Gardnerella is the prominent agent in bacterial vaginosis. The normal pH range is 4.5 to 5 and yeast vaginitis is usually in that range.
