细菌性肝脓肿细菌分析

[目的]了解细菌性肝脓肿的病原菌群分布,为临床治疗提供依据.[方法]采用厌氧培养箱,用抽氧换气钯粒催化耗氧法造成厌氧环境,对116例细菌性肝脓肿患者标本进行了厌氧细菌和需氧细菌的分离培养.[结果]116例病人中,有71例检出病原菌,总检出率61.2%.其中厌氧菌和单一需氧菌分别占阳性标本的21.1%和33.8%,两者混合阳性占45.1%.厌氧细菌和需氧细菌检出率分别为40.5%和48.3%.共检出细菌118株.厌氧细菌和需氧细菌各占46.6%和53.4%.平均每份阳性标本1.66株.[结论]细菌性肝脓肿感染病原菌中的需氧细菌多见,但同时厌氧细菌也有较高的检出率,且混合感染多.厌氧细菌感染在细菌性肝脓肿中占有很重要的地位.

STUDY ON DISTRIBUTION OF BACTERIAL HEPATIC ABSCESS

Objective To explore the distribution of bacterial hepatic abscess, so as to provide basis for clinic treatment.Methods By anaerobic culture incubator and anaerobic environment created by palladiu catalysis, the samples of 116 patients were incubated for aerobic and anaerobic respectively.Results Out of 116 patients, 71 cases were detected to be positive of pathogenic bacteria, and the positive rate was 61.2% , in which the positive rate of anaerobic and single aerobic bacteria was 40.5% and 48.3% respectively, the rate of being infected with both bacteria was 45.1%.In the 118 stains of bacte-ria, the positive rate of anaerobic and aerobic bacteria was 46.6% and 53.4% respectively.There were 1.66 stains of pathogenic bacteria per sample.Conclusion Although the pathogens of many bacterial hepatic abscess were aerobic bacterial infection, there still were patients infected with anaerobic bacteria.Also, moreover many infection were mixed with several bacteria.It indicated that anaerobic bacterial infection plays an important role in bacterial hepatic abscess.
