一、病原菌新观点传统认为引起急性腹膜炎的细菌多系消化道的常见细菌,最常见为大肠杆菌。脓液多呈黄绿色、稍稠、有粪臭味。这一概念中对大肠杆菌等需氧菌引起急性腹膜炎或腹腔感染的论述是正确的。但由于过去受厌氧菌培养技术的限制,对以脆弱类杆菌为主的厌氧菌引起急性腹膜炎或腹腔感染认识不足,论述不够完善。近年来,由于细菌培养技术的进步,在正常人胃肠道内容和继发性腹膜炎脓性渗出 First, the new point of view of pathogens Traditionally bacteria that cause acute peritonitis more than the Department of Gastrointestinal digestive common bacteria, the most common for E. coli. Pus mostly yellow-green, slightly thick, fecal odor. This concept is correct for the discussion of acute peritonitis or intraperitoneal infection of aerobic bacteria such as E. coli. However, due to the limitations of anaerobic culture techniques in the past, the understanding of acute peritonitis or abdominal infection caused by anaerobic bacteria mainly consisting of Bacteroides fragilis is insufficient, and the discussion is not perfect. In recent years, due to the progress of bacterial culture technology, in normal human gastrointestinal tract content and secondary peritonitis purulent exudation
