Candida albicans is part of our natural microflora — or the microorganisms that commonly live in or on our bodies. It can be found in the GI tract, the mouth, and the vagina. Most of the time it causes no issues, but it's possible for over-growths and infections to happen. Candida albicans is the most prevalent cause of fungal infections in people. Its species name, albicans, comes from the Latin word for "white." The yeast appears white when cultured on a plate. And in the case of certain infections, like thrush, it can create white patches.
