Abstract

Five OXA-232 carbapenemase-producing isolates, belonging to the pandemic clone sequence type 15 (ST15), were isolated from neonates and coproduced and genes. All isolates were resistant to ertapenem (MICs of >32 μg/ml) and meropenem (MICs of 4 to 8 μg/ml) and susceptible or intermediate to imipenem (MICs of 1 to 2 μg/ml). The gene was located on a ColE-type transformable plasmid of 6,141 bp. To the best of our knowledge, this is the first report of OXA-232 carbapenemase among clinical isolates in China.

摘要

从新生儿中分离出5株产OXA-232碳青霉烯酶的菌株,它们属于流行克隆序列类型15(ST15),并且共同产生了 和 基因。所有分离株对厄他培南(最低抑菌浓度>32μg/ml)和美罗培南(最低抑菌浓度为4至8μg/ml)耐药,对亚胺培南敏感或中介(最低抑菌浓度为1至2μg/ml)。 基因位于一个6141bp的ColE型可转化质粒上。据我们所知,这是中国临床分离株中首次报道OXA-232碳青霉烯酶。
