Abstract

A single Klebsiella pneumoniae strain isolated in a Bulgarian hospital was found to produce CTX-M-71, a new CTX-M variant characterized by one amino acid substitution from glycine to cysteine at position 238 in comparison to CTX-M-15. This exchange decreased the hydrolytic activity of the beta-lactamase for cefotaxime, ceftazidime, and cefepime.

摘要

在保加利亚一家医院分离出的一株肺炎克雷伯菌被发现可产生CTX-M-71,这是一种新的CTX-M变体,与CTX-M-15相比,其在第238位氨基酸处有一个从甘氨酸到半胱氨酸的替换。这种替换降低了β-内酰胺酶对头孢噻肟、头孢他啶和头孢吡肟的水解活性。
