摘要 目的研究泛耐恶臭假单胞菌40种耐药机制。方法应用法国梅里埃公司的API鉴定条/PSE5.0药敏条和美国BD公司的Phoenix NMIC/ID-109鉴定/药敏板鉴定和细菌药敏试验,应用PCR法检测1株泛耐恶臭假单胞菌临床分离株30种β-内酰胺酶基因、6种氨基糖苷类修饰酶基因(AMEs)、消毒剂/磺胺耐药基(qacE△1-sul1)、整合子(int)1、2、3等40种耐药基因,分析其分布情况。结果在本株菌,8种耐药基因阳性(二种β-内酰胺酶基(b1aCARB、b1aVIM)、4种氨基糖苷类修饰酶基因(aac(6′)-Ⅰb、aac(3)-Ⅱ、ant(3″)-Ⅰ、ant(2″)-Ⅰ)和二种整合子基因(qacE△1-sul1、intⅠ1),其它28种β-内酰胺酶基因、2种氨基糖苷类修饰酶基因(aac(6′)-Ⅱ、aac(3)-Ⅰ)和二种整合子基因(intⅠ2、intⅠ3)均为阴性。结论本株泛耐菌耐药机制为多重机制,主要与b1aCARB、b1aVIM、AMEs和Ⅰ类整合子有关。经检索中文生物医学期刊文献数据库(CMCC)和medline数据库,本研究是泛耐恶臭假单胞菌检测耐药基因最多的报道,也是第一篇从恶臭假单胞菌检出β-内酰胺酶b1aCARB和aac(3)-Ⅱ、aac(6′)-Ⅰb、ant(3″)-Ⅰ、ant(2″)-Ⅰ)耐药基因的报道。 Objective To study 40 kinds of pan-resistant genes in a pan-resistant Pseudomonas putida. Methods To detect the susceptibility of antimicrobial agents by MIC, 40 resistant genes including 30 β-lactamases genes, 6 aminoglycoside-modifying enzymes (AMEs) genes, chlorhexidine-sulfaciazine resistant gene (qacE△1- sul1) and intergron (int) 1, 2, 3, et al. One strain of pan-resistant Pseudomonas putida was measured by PCR, and verificated by DNA sequencing. Results In the strain, there are 8 kinds of positive resistant genes (b1aCARB, b1aVIM, aac(6′)- Ⅰb, aac(3)-Ⅱ, ant(3″)- Ⅰ, ant(2″)- Ⅰ, qacE△1- sul1, intⅠ1). 28 kinds genes of β-lactamases genes, 2 kinds genes of AMEs (aac(6′)- Ⅱ, aac(3)- Ⅰ ), 2 kinds genes of intⅠ (intⅠ2 and intⅠ3) are negative. Conclusion The pan-resistant Pseudomonas putida is multi-resistant mechanisms, mainly related to b1acARB, b1aVIM, AMEs and intⅠ1.
