This is the traditional surgical approach. Antibiotics are not always effective against abscesses. Neutrophils use both aerobic and anaerobic respiration. The conversion of kininogen to bradykinin is mediated by kallikrein. Lysozyme is an antibacterial agent found in neutrophil polymorphs.
Blood flow tends to slow as fluid leaves the capillaries.
The fluid exudate precedes cellular exudate. Bacterial breakdown products may act as chemo-tactic agents. All inflammatory cells are derived from bone marrow precursors. In the case of macrophages the immediate precursor is the blood monocyte. IL-1 contributes to the development of pyrexia.
