2014年中国云南地区铜绿假单胞菌耐药监测

目的 监测2014年中国云南地区铜绿假单胞菌临床分布及耐药情况.方法 收集2014年1-12月国家卫生和计划生育委员会全国细菌耐药监测网云南省28家三级医院的监测资料,按统一的方案进行铜绿假单胞菌的培养、分离、鉴定和药敏试验,判断标准按CLSI M100-S24,用Whonet5.6软件进行数据统计分析.结果 2014年云南地区28家三级医院共分离出2 873株铜绿假单胞菌,其中90.36%分离自住院患者,菌株按标本来源主要分离自痰液(60.32%)、尿(8.42%)、分泌物(8.11%)、脓液(4.70%)、血液(2.92%)等.铜绿假单胞菌对常见抗菌药物敏感度前5位依次为阿米卡星(88.7%)、哌拉西林/他唑巴坦(85.0%)、妥布霉素(83.1%)、哌拉西林(80.3%)、头孢吡肟(80.1%).对氨曲南的耐药率为59.0%;对亚胺培南、头孢他啶、美罗培南、左氧氟沙星、环丙沙星的耐药率处于20.9%~29.7%;对哌拉西林、庆大霉素、头孢吡肟、妥布霉素、哌拉西林/他唑巴坦、阿米卡星的耐药率处于10.3%~19.9%.结论 2014年中国云南地区临床分离的铜绿假单胞菌对抗菌药物的耐药性相差较大,医疗机构应加强细菌耐药监测,指导临床合理使用抗菌药物.

Investigation of antimicrobial susceptibility of Pseudomonas aeruginosa of Yunnan,China in 2014

Objective To investigate the distribution and antibiotic resistance of clinical Pseudomonas aeruginosa in Yunnan provincal of China in 2014.Methods Pseudomonas aeruginosa were collected from 28 hospitals in Yunnan surveillance of China.All hospitals were carried with the unified solution for bacteria culture,isolation,identification and antibiotic sensitivity tests according to CLSI M100-S24.The data of 2 873 strains pseudomonas aeruginosa were analyzed by WHONET5.6 software.Results 2 873 clinical strains of non-repetitive Pseudomonas aeruginosa isolates,90.36%were isolated from hospitalized patients and 60.32% from sputum,8.42% from urine,8.11% from secretion,4.70% from abscess,2.92% from blood,etc.The sensitive rates of common antimicrobial agents of Pseudomonas aeruginosa in top five were turn amikacin (88.7%),piperacillin/he azole temple (85.0%),tobramycin (83.1%),piperacillin (80.3%) and cefepime (80.1%).59.0% of the Pseudomonas aeruginosa strains were resistant to Aztreonam.20.9%-29.7% of the Pseudomonas aeruginosa strains were resistant to Imipenem,Ceftazidime,Meropenem,Ciprofloxacin and Levofloxacin.The Pseudomonas aeruginosa isolates showed the lowest resistance rate (10.3%-19.9%) to Piperacillin,Gentamicin,Cefepime,Tobramycin,Piperacillin/Tazobactam and Amikacin.Conclusion The antimicrobial susceptibility pattern varies widly with Pseudomonas aeruginosa isolated in Yunnan of China in 2014.Antimicrobial resistance sur-Monitoring the antibiotic resistant trend of Pseudomonas aeruginosa and implementing the nosocomial infection control policy become more important in hospital management setting.
