Examination of the bla(CTX-M-2) gene in plasmid pMAR-12 by sequencing and PCR analysis revealed that the bla gene and the surrounding DNA, which is closely related (99% homology) to the Kluyvera ascorbata chromosomal DNA that contains the bla(KLUA-1) gene, are located in a complex sul1-type integron, termed In35, that includes Orf513. It is possible that bla(CTX-M-2) was acquired by plasmid pMAR-12 through an uncharacterized recombinational event in which Orf513 could be involved.
通过测序和PCR分析对质粒pMAR - 12中的bla(CTX - M - 2)基因进行检测,结果显示bla基因及其周围与含有bla(KLUA - 1)基因的抗坏血酸克吕沃尔氏菌染色体DNA密切相关(99%同源性)的DNA,位于一个复杂的sul1型整合子中,称为In35,该整合子包含Orf513。bla(CTX - M - 2)有可能是质粒pMAR - 12通过一个未明确的重组事件获得的,其中Orf513可能参与其中。
