SEM of Candida Albicans is an opportunistic fungus (or form of yeast) that is the cause of many undesirable symptoms ranging from fatigue and weight gain, to joint pain and gas. The Candida Albicans yeast is a part of the gut flora, a group of microorganisms that live in your mouth and intestine. When the Candida Albicans population starts getting out of control it weakens the intestinal wall, penetrating through into the bloodstream and releasing its toxic byproducts throughout the body. Shown here are candida and epithelial cells in the human vagina. Magnification unknown.
