关于内脏穿孔后腹腔感染中微生物的性质已由许多研究者确定,大多数为多种需氧菌和厌氧菌.而且这些细菌通常是胃肠道的正常菌群,其中厌氧菌与需氧菌的比例为1000∶1.然而自1975年以来,有关厌氧菌的收集、运输、培养及鉴定技术有了很大的改进,并且根据新的标准对许多厌氧菌又作了重新分类和命名.因此,目前对腹腔内感染中厌氧菌的发现率作一评价是必要的.1974年6月～1986年6月共收集大肠穿孔腹腔内标本392份,腹腔内脓肿标本92份,术后腹部伤口感染标本95份.其中腹腔内标本培养有细菌生长 The nature of microorganisms in peritoneal infections after visceral perforation has been determined by many investigators, most of them aerobic and anaerobic bacteria, and these bacteria are usually normal flora of the gastrointestinal tract, with anaerobic bacteria and aerobic The ratio of bacteria is 1000: 1. However, since 1975, a great deal of improvement has been achieved in the techniques for the collection, transport, culture and identification of anaerobic bacteria, and many anaerobes have been reclassified according to the new standards and Therefore, it is necessary to evaluate the detection rate of anaerobic bacteria in intraperitoneal infection.A total of 392 intraperitoneal peritoneal specimens and 92 abdominal intraabdominal abscess specimens were collected from June 1974 to June 1986 95 cases of posterior abdominal wound infection specimens, including intra-abdominal bacterial culture
