Abstract

Fifty clinical Mycoplasma pneumoniae strains were isolated from 370 children with respiratory tract infections. Four strains were susceptible to macrolides, while the other 46 (92%) were macrolide resistant. The molecular mechanism of resistance was shown to be associated with point mutations in 23S rRNA at positions 2063 and 2064.

摘要

从370名呼吸道感染儿童中分离出50株临床肺炎支原体菌株。4株对大环内酯类药物敏感,而其他46株(92%)对大环内酯类药物耐药。耐药的分子机制显示与23S rRNA第2063和2064位的点突变有关。
