An epidemic of nosocomial ceftazidime-resistant Klebsiella pneumoniae was correlated with production of a ceftazidime-hydrolyzing enzyme with an isoelectric point of 5.6 (BMH-1). BMH-1 was encoded on a large transferable plasmid conferring multiple antibiotic resistance. The gene that encodes BMH-1 was identical to the gene that encodes the TEM-26 extended-spectrum beta-lactamase.
医院内耐头孢他啶肺炎克雷伯菌的流行与一种等电点为5.6的头孢他啶水解酶(BMH-1)的产生有关。BMH-1由一个赋予多重抗生素耐药性的大型可转移质粒编码。编码BMH-1的基因与编码TEM-26超广谱β-内酰胺酶的基因相同。
