Fifty-three Mycoplasma pneumoniae strains were isolated from pediatric patients in Shanghai, China, from October 2005 to February 2008. Of 53 clinical isolates, 44 (83%) were resistant to erythromycin (MICs of >128 microg/ml for all 44 strains), azithromycin, and clarithromycin. All macrolide-resistant M. pneumoniae strains harbored an A-to-G transition mutation at position 2063 in 23S rRNA genes. Forty-five (85%) clinical isolates were classified into the P1 gene restriction fragment length polymorphism type I, and six (11%) were type II.
2005年10月至2008年2月期间，从中国上海的儿科患者中分离出53株肺炎支原体菌株。在这53株临床分离株中，44株（83%）对红霉素（所有44株的最低抑菌浓度均>128μg/ml）、阿奇霉素和克拉霉素耐药。所有对大环内酯类耐药的肺炎支原体菌株在23S rRNA基因的2063位均存在A到G的转换突变。45株（85%）临床分离株被分类为P1基因限制性片段长度多态性I型，6株（11%）为II型。
