Secondary suppurative peritonitis

Secondary purulent peritonitis is often caused by acute inflammation of the abdominal cavity, acute perforation, visceral rupture, and surgical contamination. The bacteria that cause peritonitis are mostly resident bacteria in the digestive tract. The most common is Escherichia coli, followed by Streptococcus faecalis, Enterococcus, Proteus, Pseudomonas aeruginosa, and anaerobic bacteria, so they are multi-line infections. Staphylococcus is the main pathogen of peritonitis caused by surgical contamination. In the early stage of peritonitis, peritoneal bacteria invaded or digestive juice stimulated. On the one hand, the body's defense function was mobilized, and bacteria and its toxins began to be antagonized. And necrotic organ tissues assist in bacterial infections.
