摘要: 目的

了解血培养病原菌的分布及其耐药性,为临床治疗提供依据。

方法

采用回顾性调查方法,对2011年1月1日至2013年12月31日,从血标本中分离的菌株进行分析。

结果

2 418例血培养标本共分离出病原菌226株,阳性率为9.3%,其中革兰阴性杆菌143株(63.3%),革兰阳性球菌83株(36.7%),分离出最多的为大肠埃希菌99株(43.8%)、凝固酶阴性葡萄球菌43株(19.0%)和肺炎克雷伯菌20株(8.8%)。大肠埃希菌、肺炎克雷伯菌对亚胺培南、阿米卡星、派拉西林-他唑巴坦高度敏感。革兰阳性球菌对万古霉素、替考拉林高度敏感。

结论

血培养分离的病原菌以革兰阴性杆菌为主。分离病原菌的耐药情况严重,临床应加强对病原菌耐药性监测,合理使用抗菌药物。

Abstract: Objective

To understand the blood culture pathogenic bacterium distribution and drug resistance, and to provide the reference for clinical treatment.

Methods

By retrospective investigation from January 1, 2011 to December 31, 2013, the bacteria isolated from blood specimens were collected for analysis.

Results

A total of 2 418 blood culture specimens were detected, there were 226 isolates of pathogenic bacteria, and the positive rate was 9.3%, including 143 isolates of gram-negative bacilli (63.3%), 83 isolates of gram-positive cocci (36.7%). The biggest isolation was Escherichia coli (99 isolates, 43.8%), 43 isolates of coagulase-negative Staphylococcus (19.0%) and 20 isolates of Klebsiella pneumoniae (8.8%). Escherichia coli and Klebsiella pneumoniae were sensitive to imipenem, amikacin and piperacillin-tazobactam. Gram-positive coccus is highly sensitive to vancomycin and teicoplanin.

Conclusions

The main isolated blood culture pathogenic bacterium is gram-negative bacillus, and the drug resistance of isolated pathogenic bacterium is severe. The clinical pathogenic bacterium resistance monitoring and the rational use of antimicrobial agents should be strengthened.
