摘要
目的 :分析血液和骨髓标本中常见细菌分布及耐药性 ,为临床用药提供依据。方法 :采用K B纸片法对 883株细菌进行药敏试验。结果 :主要细菌有凝固酶阴性葡萄球菌、大肠埃希菌、金黄色葡萄球菌、肺炎克雷伯菌、肠球菌。耐甲氧西林金黄色葡萄球菌 (MRSA )和耐甲氧西林凝固酶阴性葡萄球菌 (MRScn)分别为 15.6%和72 .9% ;产ESBLs大肠埃希菌和肺炎克雷伯菌发生率为 2 5.3 % ,10 .9%。结论 :细菌的耐药性变迁是治疗感染 。
Objective: To analyze drug resistance anddi stribution of common bacteria from blood and bone marrow. Methods: Bacterialstrains (883) were isolated from blood and bone marrow and teste d by using K-B disk. Results: Among the 883 strains, the comm on organisms were coagulase-negative staphylococcus, E.coli, S.aureus, K.pneumo niae, Enterococcus. Methicillin-resistant Staphylococcus aureus accounted for 1 5.6% of S.aureus, 72.9% of coagulase-negative Staphylococcus were methicillin- resistant, 25.3% of E.coli and 10.9% of K.pneumoniae produced extended-spectrumbeta-lactamases. Conclusion: The change of drug resistance i s the key to the treatment of infectious diseases, especial bloodstream infectio ns and severe infection.
