What is intestinal candidiasis?

Candidiasis is a fungal infection caused by Candida, a genus of yeast that lives on the skin and inside of the mouth, throat, vagina, and GI tract. Intestinal candidiasis refers specifically to an abnormally high level of Candida detected in samples from feces, rectal swabs, or (rarely) the intestinal mucosa (the lining of the stomach or intestinal tract).
