Septicemia is a type of exudative inflammation that is characterized by the exudation of large numbers of neutrophils with varying degrees of tissue necrosis and pus formation, mostly due to septic bacterial infection. The pus is a cloudy, curd-like fluid containing a large number of degenerated necrotic neutrophils, called pus cells. Due to the different causes and sites of occurrence and lesions, septicemia is divided into abscesses, cellulitis, and surface septicemia and pus accumulation. Small abscesses can be absorbed and dissipated, while large abscesses often require surgery, incision and drainage, or puncture and extraction of pus.
