肺炎链球菌对大环内酯类抗生素的耐药率在世界范围内不断上升,这是由于携带mef(E)和mef(B)基因的移动的遗传元件的传播以及携带它们的菌株的疫苗后克隆扩增。在亚利桑那州收集的592个临床分离株在10年内的表征显示,23.6%的大环内酯类耐药。大环内酯类耐药人群的最大部分(52%)为双重mef(E)/mef(B)阳性。所有双阳性分离株均为多药耐药克隆系台湾19 F-14,大多数为多位点序列类型320,携带最近描述的转座子Tn 2010。其余的大环内酯类耐药S.肺炎菌收集物包括31%的mef(E)阳性和9%的mef(B)阳性菌株。双阳性、多药耐药的S.在七价肺炎球菌结合疫苗发布后,通过转换为非疫苗血清型,肺炎球菌克隆可能已经扩大,并且它们的成功限制了治疗选择。这一热潮可能会在亚利桑那州产生相当大的临床影响。
Rates of resistance to macrolide antibiotics in Streptococcus pneumoniae are rising around the world due to the spread of mobile genetic elements harboring mef(E) and erm(B) genes and post-vaccine clonal expansion of strains that carry them. Characterization of 592 clinical isolates collected in Arizona over a 10 year period shows 23.6% are macrolide resistant. The largest portion of the macrolide-resistant population, 52%, is dual mef(E)/erm(B)-positive. All dual-positive isolates are multidrug-resistant clonal lineages of Taiwan19F-14, mostly multilocus sequence type 320, carrying the recently described transposon Tn2010. The remainder of the macrolide resistant S. pneumoniae collection includes 31% mef(E)-positive, and 9% erm(B)-positive strains. The dual-positive, multidrug-resistant S. pneumoniae clones have likely expanded by switching to non-vaccine serotypes after the heptavalent pneumococcal conjugate vaccine release, and their success limits therapy options. This upsurge could have a considerable clinical impact in Arizona.
