Abstract
The Acinetobacter baumannii clonal complex 113/79 (CC113/79) and class 2 integrons predominate in Latin America; a relationship between these characteristics was explored. The presence of integrases was determined in successive hospital Acinetobacter isolates (163 A. baumannii isolates and 72 Acinetobacter nosocomialis isolates). Most isolates had integrons, but class 1 and 2 integrons were present significantly more often in CC109/1 and CC113/79, respectively. The high prevalence of CC113/79 in Latin America may account for the predominance of class 2 integrons.
摘要
鲍曼不动杆菌克隆复合体113/79（CC113/79）和2类整合子在拉丁美洲占主导地位；对这些特征之间的关系进行了探究。在连续收集的医院不动杆菌分离株（163株鲍曼不动杆菌分离株和72株医院感染不动杆菌分离株）中测定整合酶的存在情况。大多数分离株含有整合子，但1类和2类整合子分别在CC109/1和CC113/79中出现的频率显著更高。CC113/79在拉丁美洲的高流行率可能是2类整合子占主导地位的原因。
