Agar dilution MICs of 10 agents against 410 non-Pseudomonas aeruginosa gram-negative nonfermentative rods were determined. MICs at which 50 and 90% of the isolates were inhibited, respectively, were as follows (in micrograms per milliliter): sparfloxacin, 0.5 and 8.0; levofloxacin, 1.0 and 8.0; ciprofloxacin, 2.0 and 32.0; ofloxacin, 2.0 and 32.0; D-ofloxacin, 32.0 and > 64.0; ceftazidime, 8.0 and 64.0; piperacillin with or without tazobactam, 16.0 and > 64.0; trimethoprim-sulfamethoxazole, 0.5 and > 64.0; imipenem, 2.0 and > 64.0. With the exception of those for Stenotrophomonas maltophilia, Burkholderia cepacia, and Alcaligenes faecalis-A. odorans, agar dilution MICs for all strains tested were within 1 dilution of inhibitory (bacteriostatic) levels as determined by time-kill methodology.
测定了10种药物对410株非铜绿假单胞菌革兰氏阴性非发酵菌的琼脂稀释法最低抑菌浓度(MIC)。分别使50%和90%的分离株受到抑制的MIC如下(以微克/毫升计):司帕沙星,0.5和8.0;左氧氟沙星,1.0和8.0;环丙沙星,2.0和32.0;氧氟沙星,2.0和32.0;D-氧氟沙星,32.0和>64.0;头孢他啶,8.0和64.0;哌拉西林(无论是否联用他唑巴坦),16.0和>64.0;复方磺胺甲恶唑,0.5和>64.0;亚胺培南,2.0和>64.0。除嗜麦芽窄食单胞菌、洋葱伯克霍尔德菌和粪产碱菌-嗜臭产碱菌外,所有受试菌株的琼脂稀释法MIC均在通过时间杀菌法测定的抑菌(抑菌)水平的1个稀释度范围内。
