Candida albicans is a harmless parasite that normally coexists with beneficial bacteria and other microbes in the body. Candida levels are kept in check by the immune system and probiotics in the body. If friendly bacteria are eliminated by antibiotics or if the immune system weakens, Candida yeast can proliferate without a person noticing it. As consequence some people with this condition carry a mousy, beer smell. Infection with Candida albicans causes in women a condense, white vaginal discharge with a yeasty, sweet or fishy odor.
