中文摘要: 目的:为我院临床合理应用抗菌药物提供参考。方法:对我院2013年5月-2015年12月住院患者感染革兰氏阴性杆菌的耐药及产金属β-内酰胺酶(MBLs)情况进行回顾性分析。结果:我院2013-2015年共检出革兰氏阴性杆菌2 089株,其中肠杆菌科细菌1 456株(69.70%)、非发酵菌633株(30.30%),以大肠埃希菌、铜绿假单胞菌、肺炎克雷伯菌、鲍曼不动杆菌和阴沟肠杆菌为主。共检出耐碳青霉烯类菌株406株(19.44%),包括非发酵菌367株、肠杆菌科细菌39株。耐碳青霉烯类菌株对16种抗菌药物的耐药率均大于50%,而非耐碳青霉烯类菌株的耐药率相对较低;除氨曲南外,耐碳青霉烯类菌株对其余15种抗菌药物的耐药率均显著高于非耐碳青霉烯类菌株,差异均有统计学意义(P<0.05)。共检出产MBLs耐药菌株36株(8.87%),包括产MBLs耐药铜绿假单胞菌13株、产MBLs耐药鲍曼不动杆菌23株;未检出产MBLs耐药肠杆菌科细菌。结论:我院革兰氏阴性杆菌以肠杆菌科细菌为主;耐碳青霉烯类菌株以非发酵菌为主,耐药率普遍高于非耐耐碳青霉烯类菌株;产MBLs情况较为严重,且产酶菌株均为非发酵菌。临床应加强病原菌耐药性及产酶菌株的监测,避免不合理应用抗菌药物而造成耐药菌株的产生与传播。
英文摘要: OBJECTIVE: To provide reference for rational use of antibiotics in the clinic of our hospital. METHODS: Drug resistance of Gram-negative bacillus in the inpatients of our hospital were analyzed retrospectively during May 2013-Dec. 2015 as well as the situation of producing metallo-β-lactamase (MBLs). RESTUTS: A total of 2 089 strains of Gram-negative bacillus were detected in our hospital during 2013-2015, among which there were 1 456 strains of enterobacteria (69.70%) and 633 strains of non-fermentative bacteria, mainly involving Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Acinetobacter baumannii and Enterobacter cloacae. A total of 406 strains of carbapenems-resistant bacteria were detected (19.44%), including 367 strains of non-fermentative bacteria and 39 strains of enterobacteria. The resistant rates of carbapenems-resistant strains to 16 antibiotics were all higher than 50%, but those of non-carbapenems-resistant strains were in relative low level. Except for aztreonam, resistant rates of carbapenems-resistant strains to other 15 antbiotics were all higher than those of  non-carbapenems-resistant strains, with statistical significance (P<0.05). A total of 36 strains of producing MBLs were detected (8.87%), including 13 strains of producing MBLs drug-resistant P. aeruginosa and 23 strains of producing MBLs drug-resistant A. baumannii; producing MBLs drug resistant enterobacteria had not been found. CONCLUSIONS: Gram-negative bacillus are mainly enterobacteria in our hospital; carbapenems-resistant strains are mainly non-fermentative bacteria, resistant rate of them are commonly higher than that of non-drug-resistant strain. The situation of producing MBLs is serious, and enzyme producing strains are mainly non-fermentative bacteria. It is necessary to strengthen drug resistance of pathogen and enzyme producing strain monitoring, avoid the generation and spreading of drug-resistant strains due to irrational use of antibiotics.
