INTRODUCTION The aim of this study was to determine the antimicrobial resistance rates and their evolution in clinical isolates of Pseudomonas aeruginosa causing invasive infections in the south of Spain between 2012 and 2017. METHODS Retrospective study consisting of the collection of microbiological data from 20 hospitals (14 from Andalucía, 5 from Extremadura and 1 from Ceuta) between 2012 and 2017. The main variables studied were the antimicrobial susceptibility testing system used, interpretation criteria (CLSI or EUCAST) and the rate or percentage of resistant isolates. RESULTS The most widely used antimicrobial susceptibility testing system was MicroScan (58%). The global resistance rates varied between 25% (ciprofloxacin) and 4% (colistin) using EUCAST, and between 19% (ciprofloxacin and imipenem) and 3% (amikacin) using CLSI. The antimicrobial resistance rates were relatively stable throughout the period 2012-2017. 14% of isolates were MDR and 7% were XDR. Respiratory isolates were more resistant, particularly to ciprofloxacin and colistin, than isolates from urine or blood. CONCLUSIONS The antimicrobial resistance rates in P. aeruginosa are not particularly high in the south of Spain. The highest resistance rates were observed with ciprofloxacin, piperacillin/tazobactam and meropenem, whereas the more active antimicrobials were colistin, tobramycin and amikacin. The highest resistance rates were seen in respiratory isolates. In general, the resistance rates remained stable during the study period for most of the antimicrobials studied.

在西班牙南部引起侵袭性感染的铜绿假单胞菌临床分离株中抗菌素耐药率的演变。

引言 本研究的目的是确定 2012 年至 2017 年西班牙南部引起侵袭性感染的铜绿假单胞菌临床分离株的抗菌素耐药率及其演变。方法 回顾性研究包括从 20 家医院(14 2012 年至 2017 年期间来自安达卢西亚、埃斯特雷马杜拉 5 名和休达 1 名。研究的主要变量是所使用的抗菌药物敏感性测试系统、解释标准(CLSI 或 EUCAST)以及耐药菌株的比率或百分比。结果 最广泛使用的抗菌药物敏感性测试系统是 MicroScan (58%)。使用 EUCAST 的全球耐药率在 25%(环丙沙星)和 4%(粘菌素)之间变化,使用 CLSI 在 19%(环丙沙星和亚胺培南)和 3%(阿米卡星)之间变化。2012-2017 年期间,抗菌素耐药率相对稳定。14% 的分离株是 MDR,7% 是 XDR。与尿液或血液中的分离物相比,呼吸道分离物的耐药性更强,尤其是对环丙沙星和粘菌素的耐药性。结论 西班牙南部铜绿假单胞菌的抗菌素耐药率并不是特别高。环丙沙星、哌拉西林/他唑巴坦和美罗培南的耐药率最高,而活性更强的抗菌药物是粘菌素、妥布霉素和阿米卡星。呼吸道分离株的耐药率最高。一般而言,在研究期间,大多数研究的抗微生物药物的耐药率保持稳定。与尿液或血液中的分离物相比,呼吸道分离物的耐药性更强,尤其是对环丙沙星和粘菌素的耐药性。结论 西班牙南部铜绿假单胞菌的抗菌素耐药率并不是特别高。环丙沙星、哌拉西林/他唑巴坦和美罗培南的耐药率最高,而活性更强的抗菌药物是粘菌素、妥布霉素和阿米卡星。呼吸道分离株的耐药率最高。一般而言,在研究期间,大多数研究的抗微生物药物的耐药率保持稳定。与尿液或血液中的分离物相比,呼吸道分离物的耐药性更强,尤其是对环丙沙星和粘菌素的耐药性。结论 西班牙南部铜绿假单胞菌的抗菌素耐药率并不是特别高。环丙沙星、哌拉西林/他唑巴坦和美罗培南的耐药率最高,而活性更强的抗菌药物是粘菌素、妥布霉素和阿米卡星。呼吸道分离株的耐药率最高。一般而言,在研究期间,大多数研究的抗微生物药物的耐药率保持稳定。环丙沙星、哌拉西林/他唑巴坦和美罗培南的耐药率最高,而活性更强的抗菌药物是粘菌素、妥布霉素和阿米卡星。呼吸道分离株的耐药率最高。一般而言,在研究期间,大多数研究的抗微生物药物的耐药率保持稳定。环丙沙星、哌拉西林/他唑巴坦和美罗培南的耐药率最高,而活性更强的抗菌药物是粘菌素、妥布霉素和阿米卡星。呼吸道分离株的耐药率最高。一般而言,在研究期间,大多数研究的抗微生物药物的耐药率保持稳定。
