Trichomonas and mold can cause two kinds of vaginitis. Trichomonas vaginalis is the main pathogen of Trichomonas vaginalis, and its transmission mode is mainly sexual contact. Vaginal secretion is thin, purulent, foamy and smelly. Trichomonas vaginalis can be seen under the microscope. The treatment method is mainly oral anti-trichomonad drugs, and sexual partner treatment is needed at the same time. Mycotic vaginitis is vulvovaginal candidiasis, and the pathogen is mainly Candida, which belongs to conditional pathogenic bacteria and occurs when the body's resistance is low.
