[Role of endotoxin in pathomechanism of sepsis].

The nosocomial infections caused by Gram-negative bacteria, in this number Acinetobacter baumannii and Pseudomonas aeruginosa, have severe course and relatively high prevalence of sepsis cases. Pathomechanism of sepsis is related to activation and release of bacterial endotoxin, which is a macromolecule engaged in initiation of cytokine cascade. These mediators are responsible for heavy tissues and organs devastation.
