携带 bla(CTX-M) 或 bla(CMY) β-内酰胺酶基因的质粒的复制子分型表明,在 bla(CMY) 携带质粒和与不同类型 bla(CTX-M) 基因(I1、FII、HI2、K 和 N)相关的五种不同质粒支架中,I1 和 A/C 复制子占主导地位。这些结果证明了某些β-内酰胺酶基因与特定质粒主链的关联。
Replicon typing of plasmids carrying bla(CTX-M) or bla(CMY) beta-lactamase genes indicates a predominance of I1 and A/C replicons among bla(CMY)-carrying plasmids and five different plasmid scaffolds associated with the different types of bla(CTX-M) genes (I1, FII, HI2, K, and N). These results demonstrate the association of certain P-lactamase genes with specific plasmid backbones.
