Staphylococcus aureus. Coloured Scanning Electron Micrograph (SEM) of cells of Staphylococcus aureus bacteria, in characteristic closely packed grape-like clusters. Staphylococcus aureus is a Gram-positive bacteria of spherical (coccus) shape. They are found on healthy human skin, and on mucous membranes such as the lining of the mouth. Staphylococcus aureus is, however, commonly found in pus and is a cause boils and acne, entering the skin through a hair follicle or a cut. It is also responsible for internal abscesses and most types of acute suppurative (pus-forming) infections. Magnification: unknown.
