在PROTEKT US监测研究(2000-2003)期间,从社区获得性呼吸道感染患者中收集肺炎链球菌分离株(N = 31,001)。虽然大环内酯类(红霉素)耐药率保持稳定在29%左右,但同时含有MEF(B)和MEF(A)的耐药分离株的流行率从第1年的9.7%增加到第3年的16.4%,具有显著的区域差异。几乎所有(99.2%)的双氯芬酸(B)+mef(A)大环内酯类耐药菌株表现出多重耐药,而98.6%和99.0%分别为左氧氟沙星和泰利霉素敏感。这些菌株最常分离自儿童的耳或中耳液。在152株代表性的MEF(B)+MEF(A)分离株中,>90%与多药耐药国际台湾19 F-14克隆复合物271(CC 271)克隆相关。在PROTEKT全球研究(1999-2003年)的366株MEF(B)+MEF(A)分离株中,83.3%为CC 271,在南非、韩国和美国的流行率最高。这项研究证实了这种多药耐药肺炎球菌克隆在全球的出现和美国的流行正在迅速增加。
Streptococcus pneumoniae isolates (N = 31,001) were collected from patients with community-acquired respiratory tract infections during the PROTEKT US surveillance study (2000–2003). While the macrolide (erythromycin) resistance rate remained stable at ≈29%, the prevalence of resistant isolates containing both erm(B) and mef(A) increased from 9.7% in year 1 to 16.4% in year 3, with substantial regional variability. Almost all (99.2%) dual erm(B)+mef(A) macrolide-resistant isolates exhibited multidrug resistance, whereas 98.6% and 99.0% were levofloxacin- and telithromycin-susceptible, respectively. These strains were most commonly isolated from the ear or middle-ear fluid of children. Of 152 representative erm(B)+mef(A) isolates, >90% were clonally related to the multidrug-resistant international Taiwan19F-14 clonal complex 271 (CC271). Of 366 erm(B)+mef(A) isolates from the PROTEKT global study (1999–2003), 83.3% were CC271, with the highest prevalence seen in South Africa, South Korea, and the United States. This study confirms the increasing global emergence and rapidly increasing US prevalence of this multidrug-resistant pneumococcal clone.
