77. Husni Rousan 77 Peritonitis Pathophysiology a. Peritonitis results from contamination of normal sterile peritoneal cavity with infections or chemical irritant b. Release of bile or gastric juices initially causes chemical peritonitis; infection occurs when bacteria enter the space c. Bacterial peritonitis usually caused by these bacteria (normal bowel flora): Escherichia coli, Klebsiella, Proteus, Pseudomonas d.
