武汉市青山区血培养病原菌的分布及耐药性分析

目的了解本地区阳性血培养病原菌分布及耐药性。方法运用全自动血培养系统对1315份血培养标本进行培养,125例阳性,对培养阳性进行细菌鉴定和药敏试验。结果血培养125例阳性,阳性率为9.5%;G-杆菌63株占50.4%,以大肠埃希菌及肺炎克雷伯菌为主;G＋球菌59株占47.2%,以表皮葡萄球菌、金黄色葡萄球菌为主;真菌3例占2.4%,以白假丝酵母菌为主。药敏结果：葡萄球菌对万古霉素、复方新诺明、呋喃妥因的敏感率均高于80%,但耐甲氧西林葡萄球菌的耐药率较高。产ESBLs大肠埃希菌和产ESBLs肺炎克雷伯菌及铜绿假单胞菌、不动杆菌有较高耐药率。结论血培养有一定阳性率,以大肠埃希菌、肺炎克雷伯菌和葡萄球菌为主,均有较高耐药率,临床应及时送检血培养,依据药敏结果选用抗菌药物进行治疗。

Distribution and drug resistance analysis of the pathogens from blood cultures in Qingshan district of Wuhan

Objective To understand the distribution and drug resistance of the pathogens from blood cultures in this region.Methods The positive cases with bacteria cultured from blood samples were identified by automated blood culture system,and their drug resistance were tested.Results 125 positive cases cultured from 1315 blood samples were separated,the isolation rate was 9.5%;Gram negative bacteria was 63 cases(50.4%),incliding Escherichia coli and Klebsiella pneumoniae.Gram positive coccus was 59 cases(47.2%),in...
