Abstract
CTX-M-14 beta-lactamase was identified in a stool isolate of Shigella sonnei and in blood isolates of Escherichia coli (one isolate) and Klebsiella pneumoniae (two isolates) from different parts of Korea. The amino acid sequence differed by one amino acid from CTX-M-9 (Ala-231--> Val) and was identical to that of beta-lactamases recently found in China and Japan.
摘要
在韩国不同地区的宋内志贺菌粪便分离株以及大肠埃希菌（1株）和肺炎克雷伯菌（2株）的血液分离株中鉴定出CTX-M-14β-内酰胺酶。其氨基酸序列与CTX-M-9仅相差1个氨基酸（丙氨酸231→缬氨酸），并且与最近在中国和日本发现的β-内酰胺酶相同。
