【摘要】：目的探讨某医院2014年收治患者感染病原菌的构成及耐药性,为医院感染的控制及临床合理应用抗菌药物提供参考依据。方法对患者送检的临床标本进行分离培养,并通过VITEK 2 Compact及ATB细菌鉴定分析仪进行病原菌的鉴定及药敏试验。结果共分离出病原菌2 393株,其中革兰阴性杆菌占62.4%;革兰阳性球菌占21.9%;真菌占15.7%。大肠埃希菌、肺炎克雷伯菌、金黄色葡萄球菌、铜绿假单胞菌及白色念珠菌占病原菌的前5位。大肠埃希菌、肺炎克雷伯菌产ESBLs的检出率分别为62.4%、41.6%,对亚胺培南、阿米卡星耐药率低;铜绿假单胞菌及鲍曼不动杆菌对多种抗菌药物的耐药率高于60.0%;葡萄球菌中MRSA、MRCNS的检出率分别为69.2%、73.6%,对万古霉素、利奈唑胺、替加环素100.0%敏感;白色念珠菌对抗真菌药物的耐药率低于5.0%。结论病原菌对部分抗菌药物耐药性严重,需要不断提高病原学送检及细菌耐药监测工作,以促进临床合理使用抗菌药物。
[Abstract]:Objective to explore the composition and drug resistance of the pathogenic bacteria in a hospital in 2014, and to provide reference for the control of hospital infection and the rational application of antibiotics in clinic. Methods the clinical specimens were isolated and cultured, and the pathogen identification and drug sensitivity test were carried out by VITEK 2 Compact and ATB bacterial identification analyzer. Results 2393 strains of pathogenic bacteria were isolated, of which gram-negative bacilli accounted for 62.4%, gram-positive cocci accounted for 21.9%, fungi accounted for 15.7%. Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans in the top 5. The detection rate of ESBLs in Escherichia coli and Klebsiella pneumoniae was 62.4%, 41., respectively. 6%, the resistance rate of Amikacin to imipenem was low; the resistance rate of Pseudomonas aeruginosa and Acinetobacter Bauman was higher than that of 60%. The detection rates of MRSA and MRCNS in Staphylococcus were 69.2% and 73.6% respectively, and vancomycin, linezolid and tigocycline 100% sensitivity, and the resistance rate of Candida albicans against fungal drugs was lower than that of 5.0%. knot. Pathogen resistance to some antibiotics is serious. It is necessary to continuously improve the surveillance of pathogens and drug resistance, so as to promote the rational use of antibiotics in clinic.
