Candida albicans occurs naturally as a commensal of mucous membranes and in the digestive tract of humans and animals. It accounts for up to 70% of Candida species isolated from sites of infection and has been reported as a causative agent of all types of candidiasis. Environmental isolations are usually from sources contaminated by human or animal excreta, such as polluted water, soil, air and plants.
