Thismicro-organism is found in acute abscesses and boils, sometimes also in 692 EXPLORATORY PUNCTURE. infectious osteomyelitis and ulcerative endocarditis. In addition to otherportals, it may enter the tissue through abrasions or the hair-follicles. Morphology. In cover-glass preparations they appear as small, roundbodies scattered among the pus-cells, rarely within them, single, in pairsor in clusters. They stain readily with the basic aniline dyes. (SeeFig. 275.) Fro. 19 Pus with staphylococcus. X 800. (Flugge.) 2. Staphylococcus Pyogenes Albus. It is also found in acute abscesses,but less often than the aureus, and is less virulent. It is morpholog-ically identical with the aureus/ but develops no pigment. The surfacecultures are milky white, and the mass at the bottom of the liquefyinggelatin is white. 3. Staphylococcus epidermidis albus (Welch) closely simulates Staphy-lococcus pyogenes albus. It is the most common micro-organism on thesurface of the body, and is often present in parts of the epidermis toodeep for disinfection, save by heat. It is supposed to be the usual causeof stitch-abscess. 4. Streptococcus Pyogenes. It is found in acute abscesses, erysipelas,otitis media, puerperal metritis, infectious endocarditis, pseudodiphtheria,scarlatinal angina, and most purulent inflammations of a phlegmonouscharacter. It is the organism most commonly found in inflammationsha
