Yeast vaginitis and syphilis are unrelated. Yeast vaginitis is caused by a disruption in the vaginal environment leading to an infection with Candida albicans, resulting in increased vaginal discharge. This is accompanied by itching of the vulva and the discharge may appear like cottage cheese or have a curd-like texture. However, syphilis is caused by the infection of the bacterium Treponema pallidum. It is a sexually transmitted disease characterized primarily by painless ulcers on the genitals. The treatment methods for the two are also different. Yeast vaginitis can be treated by external washing with baking soda and inserting clotrimazole vaginal suppositories, typically resolving within about a week. Treatment for syphilis, on the other hand, generally involves intravenous injections of penicillin. (Medication use should be supervised by a professional doctor.)
