The study evaluated the activity of ceftolozane-tazobactam (C/T) against 94 unique clinical isolates of complex (ECC). No difference was observed according to the ECC cluster. The activity greatly varied depending on the β-lactamase-producing profile: 100%, 67%, and 19% of wild-type, extended-spectrum β-lactamase (ESBL)-producing, and AmpC-overproducing strains, respectively, were susceptible to C/T. The use of C/T could be of interest for the treatment of some infections caused by ESBL-producing AmpC-nonoverexpressing ECC isolates.
本研究评估了头孢洛扎他唑巴坦(C/T)对 94 株独特的复杂性(ECC)临床分离株的活性。根据 ECC 聚类,未观察到差异。根据产β-内酰胺酶的表型,其活性有很大差异:野生型、产超广谱β-内酰胺酶(ESBL)和产 AmpC 酶的菌株,对 C/T 的敏感性分别为 100%、67%和 19%。C/T 的使用可能对治疗某些由产 ESBL 但不表达 AmpC 的 ECC 分离株引起的感染有意义。
