Infection become localized in the form of abscess, bacteria responsible for this is:
Correct Answer: Staphylococci
Description: Pyogenic organisms, predominantly Staphylococcus aureus, cause tissue necrosis and suppuration. Pus is composed of dead and dying white blood cells, predominantly neutrophils, that have succumbed to bacterial toxins. An abscess is surrounded by an acute inflammatory response composed of a fibrinous exudate, oedema and the cells of acute inflammation. Granulation tissue (macrophages, fibroblasts and new blood vessel proliferation) forms later around the suppurative process and leads to collagen deposition. If it is not drained or resorbed completely, a chronic abscess may result. If it is partly sterilised with antibiotics, an antibioma may form.
