当今,腹腔感染的合理有效抗菌治疗,要求掌握引起感染的细菌学知识。随着医学科学的进展,细菌检验技术的现代化,引起感染的细菌学知识不断迅速深入和进步。对于腹腔外科感染细菌学的研究,可以提高患者治愈率,降低死亡率。一、正常胃肠道菌丛的研究1974年Drasar 及Hill 的研究结果证明:1.正常空胃是无菌的。其原因为:(1)游离盐酸的杀菌作用;(2)pH 值在3以下。如果进餐后,来自食物及唾液的链球菌、肠杆菌、乳酸杆菌则其浓度可达10~(1.5)/毫升。2.正常
Today, the rational and effective antimicrobial treatment of intra-abdominal infections require mastery of the bacteriological knowledge that causes the infection. With the progress of medical science, the modernization of bacterial testing technology has led to rapid and thorough bacteriological knowledge of infection. Bacteriological study of intraperitoneal surgical infection, can improve the cure rate of patients, reduce mortality. First, the normal gastrointestinal flora research Drasar and Hill in 1974 the results show that: 1. The normal empty stomach is sterile. The reason is: (1) bactericidal effect of free hydrochloric acid; (2) pH value below 3. Streptococcus, Enterobacter, and Lactobacilli from food and saliva can reach a concentration of 10 ~ (1.5) / ml after a meal. Normal
