CTX-M-encoding genes from Klebsiella spp. strains isolated in 2000 and 2006 were characterized as well as their genetic environment. CTX-M-2 variants were predominant in Klebsiella pneumoniae strains, which showed a greater variability in bla(CTX-M) genes, integrons, and plasmids in 2006 when compared to strains collected in 2000. CTX-M-9-producing Klebsiella oxytoca was identified in 2000 as clonal dissemination.
对 2000 年和 2006 年分离的克雷伯氏菌属菌株中的 CTX-M 编码基因及其遗传环境进行了特征分析。在 2006 年，肺炎克雷伯菌菌株中以 CTX-M-2 变体为主，与 2000 年采集的菌株相比，bla(CTX-M)基因、整合子和质粒的变异性更大。2000 年鉴定出产 CTX-M-9 的奥克西托拉克雷伯菌呈克隆传播。
