感染是急、慢性肝病常见的合并症之一,60年代中期,国内报告各类型肝硬化并发感染者占5.8～10%,而且随着广谱抗菌素的广泛使用,革兰氏阴性杆菌感染发病率有所增加。国内细菌学证实的63例,阴性杆菌占54例(85.7%),其中大肠杆菌38例(60.3%)。一些杂菌,如产气杆菌、绿脓杆菌、未定型革兰氏阴性杆菌以及甲型链球菌、白色葡萄球菌等均可为致病菌。重症肝炎时机体抵抗力下降,细菌通过肠道、胆道、泌尿道或呼吸道侵入,有时无明显的感染灶,由肠道经过门静脉进入者为多。肝病时肝内网状内皮细
Infection is one of the common complication of acute and chronic liver disease. In the mid-1960s, the domestic reports of all types of cirrhosis patients accounted for 5.8 ~ 10%, and with the widespread use of broad-spectrum antibiotics, the incidence of gram-negative bacilli Has increased. 63 cases were confirmed by bacteriology in China, 54 cases (85.7%) were negative bacilli, of which 38 cases were Escherichia coli (60.3%). Some bacteria, such as Aerobacter aerogenes, Pseudomonas aeruginosa, non-stereotyped Gram-negative bacilli and Streptococcus A, Staphylococcus aureus, etc. can be pathogenic bacteria. Severe hepatitis, the body resistance decreased bacteria invade through the gut, biliary tract, urinary tract or respiratory tract, and sometimes no significant focus of infection, from the intestine through the portal vein were more.
