摘要: 目的 收集并分析某三甲医院5种重要临床分离菌的耐药性变迁,为临床合理选用抗菌药物提供参考。方法 各类临床分离菌采用MicroScan WalkAway 96 PLUS进行鉴定和药敏实验,采用WHONET5.6软件对数据进行统计分析。结果 2012~2016年,每年的临床分离菌数量分别为1 531株、1 434株、1 697株、1 499株和1 441株。大肠埃希菌和肺炎克雷伯菌中产超广谱β内酰胺酶(ESBL)菌株检出率呈逐年下降趋势。5年来大肠埃希菌对碳青霉烯类抗菌药物的耐药率基本稳定;肺炎克雷伯菌对碳青霉烯类耐药率呈上升趋势。铜绿假单胞菌对包括亚胺培南和美罗培南在内的所有监测的抗菌药物的耐药率均有所下降。鲍曼不动杆菌对碳青霉烯类的耐药率由32.8% 逐步上升至82.3%。耐甲氧西林金黄色葡萄球菌的检出率由 2012年的45.2% 逐年下降至2016年的37.5 %。结论 本院近5年肺炎克雷伯菌和鲍曼不动杆菌对碳青霉烯类的耐药率逐年上升,临床应引起足够的重视。

Abstract: Objective To investigate the clinical distribution and drug resistance of the five clinically important bacteria isolates in the hospitals from 2012 to 2016 in order to provide reference for the proper use of antibiotics. Methods Tests of bacterial identification and antibiotic susceptibility were performed with the MicroScan WalkAway 96 PLUS bacterial identification system. All of the data were analyzed by WHONET5.6 software. Results An average of 1 520 isolates were harvested each year. Among them Escherichia coli and Klebsiella pneumonia producing extended-spectrum β-lactamase (ESBL) strains showed a downward trend. The resistance rate of E. coli to carbapenem-based antibiotics was basically stable during the five years studied, and that of K. pneumoniae to carbapenems showed an upward trend. Pseudomonas aeruginosa presented decreased resistance to all of the monitored antimicrobials, including imipenem and meropenem. Carbapenem resistance rate of Acinetobacter baumannii gradually increased from 32.8% to 82.3%. The positive rate of methicillin-resistant Staphylococcus aureus dropped from 45.2% in 2012 to 37.5% in 2016. Conclusion The prevalence of carbapenem-resistant K. pneumoniae and A. baumannii is increasing and of great concern in recent years.
