Nine imipenem-resistant Pseudomonas aeruginosa isolates were found to contain a variety of metallo-beta-lactamase genes, including bla(IMP-1), bla(IMP-7), bla(VIM-2), bla(VIM-6), and the novel bla(IMP-26). Multilocus sequence typing showed a diversity of sequence types. Comparison with isolates from an earlier study showed that the epidemic clones from 2000 have not become established.
发现 9 株耐亚胺培南铜绿假单胞菌分离株含有多种金属β-内酰胺酶基因,包括 bla(IMP-1)、bla(IMP-7)、bla(VIM-2)、bla(VIM-6)和新型 bla(IMP-26)。多位点序列分型显示出多种序列类型。与早期研究的分离株比较表明,2000 年的流行克隆尚未建立。
