| 摘 要： | 目的检测分析鲍氏不动杆菌耐药性及相关耐药基因。方法采用K-B法(CLSI 2008年标准)测定鲍氏不动杆菌临床分离株耐药性;PCR方法检测TEM、SHV、CTX-M、I MP、VI M、OXA-23、OXA-24耐药基因以及Ⅰ、Ⅱ类整合酶。结果 130株鲍氏不动杆菌,除阿米卡星和碳青霉烯类外,对其他抗菌药物耐药率非常高,TEM、SHV、CTX-M、Int1、Int2基因阳性率分别为68.5%、10.8%、17.7%、75.4%、0;51株耐碳青霉烯类鲍氏不动杆菌中I MP、VI M、OXA-23、OXA-24基因阳性率分别为25.5%、19.6%、72.5%、0。结论鲍氏不动杆菌耐药性较高,携带TEM型β-内酰胺酶、OXA-23、I MP和VI M型碳青霉烯酶基因和Ⅰ类整合酶;产生OXA-23型碳青霉烯酶和金属酶是医院鲍氏不动杆菌对碳青霉烯类耐药的主要机制。

| Abstract: | OBJECTIVE To detect and analyze the antibiotic resistance and resistance related genes from Acinetobacter baumannii.METHODS Antimicrobial susceptibility test was done on A.baumannii clinical isolated by Kirby-Bauer method.Results were assessed according to the standards recommended by CLSI(2008).The genotype of TEM,SHV,CTX-M,IMP,VIM,OXA-23,OXA-24 and class I,II integrase was performed by polymerase chain reaction(PCR).RESULTS Sensitive to antibiotics except Amikacin and carbapenem were low in 130 strains A.... |
