What Is It?
Candidiasis is an infection caused by Candida fungi, most of by Candida albicans. These fungi are found almost everywhere in the environment. Some may live harmlessly along with the abundant "native" species of bacteria that normally colonize the mouth, gastrointestinal tract and vagina.
Usually, Candida is kept under control by the native bacteria and by the body's immune defenses. If the mix of native bacteria is changed by antibiotics or the body moisture that surrounds native bacteria undergoes changes in its acidity or chemistry, it can allow yeast to thrive and cause symptoms.
