Abstract

Tetracycline is an important component of combination therapies for Helicobacter pylori eradication. Twenty-nine tetracycline-resistant isolates requiring MICs ranging from 4 to 16 microgram/ml were isolated from Korean (22 of 460) and Japanese (7 of 105) patients. Interestingly, all of the 29 tetracycline-resistant isolates exhibited cross-resistance to metronidazole, and the cross-resistance was transferred to tetracycline-sensitive H. pylori strains.

摘要

四环素是根除幽门螺杆菌联合疗法的重要组成部分。从韩国患者(460例中的22例)和日本患者(105例中的7例)中分离出29株四环素耐药菌株,其最低抑菌浓度(MIC)范围为4至16微克/毫升。有趣的是,所有29株四环素耐药菌株均对甲硝唑表现出交叉耐药性,且这种交叉耐药性可转移至四环素敏感的幽门螺杆菌菌株。
