本院2009年至2010年1476株临床标本常见病原菌分布及耐药件分析

目的 分析本院1476株临床常见病原菌的分布及其对常用抗菌药物的耐药情况,为临床合理用药提供依据.方法 对2009年1月至2010年8月送检的各类标本进行培养分离出的1476株病原菌,采用BD公司PHOEIX-100全自动病原菌鉴定药敏仪进行病原菌鉴定及其抗菌药物敏感性试验,再以WHONET5.3系统对病原菌分布及耐药性监测数据进行分析.结果 分离出的1476株病原菌中,革兰阴性杆菌1206株,革兰阳性球菌270株,分别占81.7%,18.3%.检出的病原菌中最常见的菌为大肠埃希菌、肺炎克雷伯菌、金黄色葡萄球菌、铜绿假单胞菌,分别占20.2%、17.5%、13.2%、11.4%.产超广谱β-内酰胺酶(ESBLs)的大肠埃希菌和肺炎克雷伯菌的检出率分别为65.9%、48.1%;耐甲氧西林金黄色葡萄球菌(MRSA)和凝固酶阴性葡萄球菌(MRCNS)分别为79.2%、68.4%.未发现葡萄菌属对万古霉素、呋喃妥因耐药.革兰阴性杆菌对碳氢霉烯类抗菌药敏感度高.结论 分离出的病原菌耐药现象普遍存在,开展连续的耐药性监测对指导临床合理应用抗菌药物及控制感染病原菌有重要意义.

Abstract：

Objective Analyzing the distribution of 1476 strains of clinical common pathogens and their antimicrobial resistance, provide reference the reasonable use of antimicrobial drugs for clinical.Methods Using BD company PHOEIX-100 Automatic Pathogen Identification to Pathogen identify 1476 strains of pathogens which were got from the various isolated and cultivated samples which were examined from 2009 January to 2010 August and its antibacterial Drug Susceptibility Test, then with WHONET5. 3 system to analyze monitoring data of the pathogen distribution and resistance. Results In 1476 strains of pathogens isolated, gram-negative bacteria had 1206 strains occupying 81.7% ; Gram-positive cocci had 270 stains occupying 18. 3%. The most common detected pathogen were Escherichia coli, Klebsiella pneumoniae,Staphylococcus aureus and Pseudomonas aeruginosa, which accounted for 20. 2% ,17. 5% ,13. 2% ,11.4%.The ESBLs producing E. coli and K. pneumoniae accounted for 65. 9% ,48. 1% ; Also methicillin-resistant S. aureus (MRSA) accounted for 79. 2% and methicillin-resistant coagulase-negative staphylococci (MRCNS) accounted for 68.4%. It isnt found yet that grape genus to vancomycin, nitrofurantoin can resist drug.Gram-negative bacilli to antimicrobial vinyl hydrocarbon mold degree of sensitivity is high. Conclusion The isolated pathogen's resistance of drug is widespread. It is important to guide clinical reasonable use of antibiotics and control infectious pathogens that carry out continuous monitoring of drug resistance.
