Investigation of plasmid-borne AmpC β-lactamase genes in Escherichia coli and Klebsiella spp. revealed blaCMY-2-like genes predominantly in E. coli and blaDHA genes equally distributed between both species. This distribution remained stable over time, but blaACT/MIR-like genes, initially common in Klebsiella spp., were not identified in more recent isolates.
对大肠杆菌和克雷伯菌属中质粒携带的AmpC β-内酰胺酶基因的研究表明,blaCMY-2样基因主要存在于大肠杆菌中,而blaDHA基因在这两个菌种中分布均匀。这种分布随时间保持稳定,但最初在克雷伯菌属中常见的blaACT/MIR样基因在最近分离出的菌株中未被发现。
