Strain characteristics.

*Strain belonging to European clones I–III (+) or not belonging to these clones (−). All isolates have been identified to species by one or more genotypic methods [1], [33], [34].†Outbreak-associated (+) strain (i.e., common AFLP profile in >2 patients and with same time-space-origin) or (−) sporadic strain.‡Multidrug-resistant (+) strain (i.e., resistant to more than two of the following drug classes or combinations: cephalosporins, carbapenems, ampicillin-sulbactam, quinolones and aminoglycosides) or (−) susceptible strain.* 属于欧洲克隆株I~III的菌株记为(+)，不属于该类克隆株的菌株记为(−)。所有分离株均通过一种或多种基因型方法完成物种鉴定[1, 33, 34]。 † 与暴发相关的菌株记为(+)（即：在超过2例患者中存在共同的扩增片段长度多态性（Amplified Fragment Length Polymorphism, AFLP）图谱，且具有相同的时空来源），散发性菌株记为(−)。 ‡ 多重耐药菌株记为(+)（即：对以下超过2类药物或药物组合耐药：头孢菌素类、碳青霉烯类、氨苄西林-舒巴坦、喹诺酮类及氨基糖苷类），药物敏感菌株记为(−)。
