Candidiasis: Disease caused by the yeast Candida albicans. Candida albicans can cause vaginal yeast infections, diaper rash, skin rashes that emerge in moist, warm folds of skin, and thrush (white patches inside the mouth and throat). Candidiasis tends to develop when the normal balance of bacteria is upset, as sometimes occurs with the use of antibiotics. Prevention measures include the use of probiotics, and in some cases, dietary changes. Candidiasis can be treated with antifungal medications. Candidiasis is usually a minor and easily addressed problem, but it can be an important problem for those with immune-system disorders, such as AIDS.
