(B) the pathogenesis
bacteria invade the hair follicle and their sebaceous glands and sweat glands, in hair follicles and surrounding tissue multiply rapidly, producing toxins, causing local tissue degeneration, necrosis, and the center of the formation of boils, the performance of local congestion, exudation, induration. Aggregation of neutrophils to the damaged body tissue cells and bacteria to be destroyed, and he gradually necrosis and dissolution, the formation of abscesses in the dermis. Due to staphylococcus aureus, coagulase contain toxins, so the formation of pus bolt, protruding outward. Swelling and induration clinically visible in the center of a yellow-white pus plug. This is staphylococcus aureus infected lesion characteristics. ulceration after discharge pus, abscess gradually by the new fibrous tissue repair and healing.[Sign]
