Carbapenemase-producing (CP) Enterobacteriaceae are largely responsible for the rapid spread of carbapenem-resistant Enterobacteriaceae (CRE). Distinguishing CP-CRE from non-CP-CRE has important infection control implications. In a cohort of 198 CRE isolates, for isolates that remained susceptible or intermediate to some carbapenem antibiotics, an ertapenem MIC of 0.5 μg/ml and meropenem, imipenem, and doripenem MICs of 2 μg/ml were best able to distinguish CP-CRE from non-CP-CRE isolates.
产碳青霉烯酶(CP)的肠杆菌科细菌在很大程度上导致了耐碳青霉烯类肠杆菌科细菌(CRE)的迅速传播。区分产碳青霉烯酶的耐碳青霉烯类肠杆菌科细菌(CP-CRE)和非产碳青霉烯酶的耐碳青霉烯类肠杆菌科细菌(non-CP-CRE)对感染控制具有重要意义。在一组198株CRE分离株中,对于那些对某些碳青霉烯类抗生素仍敏感或中介的分离株,厄他培南的最低抑菌浓度(MIC)为0.5μg/ml,美罗培南、亚胺培南和多利培南的MIC为2μg/ml时,最能区分CP-CRE和non-CP-CRE分离株。
