鲍氏不动杆菌5年感染监测

Acinetobacter baumannii: Five Year Infection Surveillance

目的监测近5年来临床标本鲍氏不动杆菌的分离率、分布特点及耐药情况。方法对近5年来临床分离的鲍氏不动杆菌分布科室、感染部位及对20种不同抗菌药物耐药率进行统计分析。结果在统计年限内,我院共分离到鲍氏不动杆菌523株,感染部位以下呼吸道为主,科室以重症监护中心最多,与同期分离菌株相比,检出率从2000年3.9%依次上升至2004年11.1%,对20种不同抗菌药物的耐药率呈不同程度增强,对亚胺培南、头孢哌酮/舒巴坦、氨苄西林/舒巴坦敏感性最高。结论鲍氏不动杆菌的分离率逐年增高,耐药性逐渐增强,多重耐药菌株分离率高,应引起高度重视。

OBJECTIVE To study the isolation rate of Acinetobacter baumannii, characteristics of infection distribution and antimicrobial resistance rates. METHODS Surveillance data of A. baumannii infection of wards, its distribution and resistance rates to 20 kinds of antibiotics in our hospital for 5 years were analyzed. RESULTS During the 5-year infection surveillance, 523 strains of A. baumannii were isolated in our hospital mostly from sputum. The commonest site was lower respiratory tract. The ward with the highest incidence of A. baumannii infection was ICU. The isolation rate was 11.1% in 2004, though 3.9% in 2000. A. baumannii was resistant to 20 kinds of antibiotics, especially to imipenem, cefoperazone/sulbactam and ampicillin/sulbactam. CONCLUSIONS The isolation rate of A. baumannii and antimicrobial resistance rate are increasing year by year. The increased rate of multidrug-resistance should be payed more attention.
