Abstract

Carbapenems L-749,345 and imipenem had the lowest MICs at which 90% of isolates were inhibited (0.5 microg/ml) of 14 antimicrobial agents tested against 76 multiresistant gram-negative clinical isolates with TEM- or SHV-type extended-spectrum beta-lactamases and chromosomal or plasmid-determined AmpC beta-lactamases, but the MIC of L-749,345 for one isolate of Klebsiella pneumoniae was 16 microg/ml.

摘要

碳青霉烯类药物L-749,345和亚胺培南在针对76株具有TEM型或SHV型超广谱β-内酰胺酶以及染色体或质粒介导的AmpCβ-内酰胺酶的多重耐药革兰氏阴性临床分离株测试的14种抗菌药物中,对90%分离株产生抑制作用的最低MIC(最低抑菌浓度)值最低(0.5微克/毫升),但L-749,345对一株肺炎克雷伯菌分离株的MIC为16微克/毫升。
