血标本细菌培养菌株的分布

The distribution of organism in blood

目的:分析菌血症、败血症的菌种分布,为菌血症、败血症的临床抗感染治疗经验用药提供帮助。方法 全自动血培养仪检测有细菌生长后,转种相应平板,36℃孵育18～24小时,用全自动微生物鉴定仪进行菌种鉴定。结果 血液标本中分离出的细菌菌种分布较广,以金黄葡萄球菌和大肠埃希氏菌为主,占40％以上,微球菌及凝固酶阴性葡萄球菌的分离率占20％,伤寒沙门氏菌及副伤寒沙门氏菌的分离率占10％。结论;对菌血症、败血症的患者应尽快作出微生物学诊断,争取尽早在药敏试验结果指导下进行临床抗感染治疗。

Objective: To provide basis for anti-infection therapy of Septicemia. METHODS: The growth of organisms in samples (blood) is detected by BacT/Alert 120.The organisms are identified by MicroScan WalkAway 40. RESULTS:The organisms sorts in blood are varies. S. aureas and E. cob is up for 40％; Micrococcus and coagulase-negative staphylococci is account for 20％; S. typhi and S. paratyphi is account for 10％。CONCLUSION:We should as fast as possible make the microbiological diagmpsis to the septicemia,and as early...
