Abstract
Thirty-six isolates of carbapenem-resistant Pseudomonas aeruginosa were studied. Pulsed-field gel electrophoresis revealed the presence of two clones. One clone carried a bla(IMP-1) gene identical to that first described in Japan. The other clone carried a bla(IMP-1) variant containing four silent mutations. One isolate with a unique pulsed-field gel electrophoresis pattern contained bla(IMP-7).
摘要
对36株耐碳青霉烯类铜绿假单胞菌分离株进行了研究。脉冲场凝胶电泳显示存在两个克隆。一个克隆携带与日本首次描述的bla(IMP-1)基因相同的基因。另一个克隆携带一个包含四个沉默突变的bla(IMP-1)变体。一株具有独特脉冲场凝胶电泳图谱的分离株含有bla(IMP-7)。
