摘要
目的:了解我院新生儿血培养病原菌的分布及耐药性分析。方法:法国生物梅里埃公司的BacT/A lert3D进行血液培养,菌株鉴定采用法国生物梅里埃公司的VITEK 60分析仪,药敏试验采用K-B法。结果:新生儿血培养中革兰阳性球菌占85.7%,凝固酶阴性的葡萄球菌(CNS)占73.6%,其中,表皮葡萄球菌占33%,溶血葡萄球菌占20.8%,其它凝固酶阴性的葡萄球菌占19.8%,革兰阴性杆菌只占11%。结论:CNS是引起新生儿败血症的主要病原菌,苯唑西林耐药凝固酶阴性的葡萄球菌占88%,对此类菌引起的感染宜首选万古霉素、力奈唑烷、利福平、喹奴普汀?达福普汀。
Objective： To study the pathogen distribution and antibiotic resistance after neonatal blood culture in our hospital. Methods：Blood was cultured in BacT/Alert3D of Bio - Merieux of France. The clinical isolates were identified by VITEK - 60 of Bio - Merieux of France. Antibiotic susceptive test was done by Kirby - Bauer method. Results ： In newborn blood culture gram - positive cocci accounted for 85. 7% , Coagulase negative Staphylococcus （CNS） for 73. 6% , which accounted for 33% of Staphylococcus epidermidis, Staphylococcus hemolysis accounted for 20. 8%. The other coagulase - negative Staphylococcus accounted for 19. 8%, gram -negative bacilli account for only 11%. Conclusion： CNS is the main cause of neonatal sepsis pathogens, methicillin - resistant coagulase - negative Staphylococcus accounted for 88% . Curing infections caused by of these bacteria. Quinupristin/Dalfopr, vancomycin, rifampicin, and Linezolid should be of the first choice.
