摘　　要：目的 :分析目前腹腔感染患者致病菌谱及其特点。 方法 :对 4 5 4例因腹腔感染入院的患者标本进行分离培养 ,采用Bio -MerieuxVITEK -ams自动分析鉴定仪及GNI、GPI、ANI和YBC卡进行细菌鉴定。 结果 :在 4 5 4例标本中 ,细菌阳性检出率为 75 11% ,其中需氧菌检出率为 81 6 7% ,厌氧菌检出率为 12 15 % ,真菌检出率为 6 18%。在所有检出菌中 ,肠球菌的构成增高显著 ,出现了产超广谱 β -内酰胺酶的大肠埃希菌和肺炎克雷伯菌。 结论 :近 3年腹腔感染主要的致病菌是大肠埃希菌和肺炎克雷伯菌 ,多重耐药的肠球菌已上升到第 3位 ,铜绿假单胞菌有下降的趋势。产超广谱 β -内酰胺酶的大肠埃希菌和肺炎克雷伯菌的检出率正在逐年升高。Objective To analyze the changes and characteristics in pathogenic spectra of bacteria from patients with intra-abdominal infection Methods In recent three years samples of in-patients suffering from intra-abdominal infection were obtained for isolation and culture.Bacteria were indentified by bio-Merieux VITEK-ams autobiochemistry analysis equipment and GNI,GPI,ANI,YBC card.Results In all samples,the positive rate of isolation was 75.11%,among them aerobe was 81.67%,anerobe 12.15% and fungus 6.18%.In all pathogenic bacteria the proportion of enterococci in intra-abdominal infection increased significantly.It was shown that E.coli and K.pneumoniae produced extended-spectrum β-lactamases.Conclusion In recent three years,E.coli and K.pneumoniae were the dominant pathogenic bacteria enterococci of a multiple drug resistance character has moved upwards to the third place,with P.aeruginosa as the less dominant bacterium in current intra-abdominal infections.The positive rates of isolation of E.coli and K.pneumoniae produced extended-spectru, and β-lactamases go up year by year.
