Candidiasis is a fungal infection caused by yeasts that belong to the genus Candida. There are over 20 species of Candida yeasts that can cause infection in humans, the most common of which is Candida albicans. Candida
yeasts normally reside in the intestinal tract and can be found on
mucous membranes and skin without causing infection; however, overgrowth
of these organisms can cause symptoms to develop. Symptoms of
candidiasis vary depending on the area of the body that is infected.
