Fosmidomycin (FR-31564), a phosphonic acid derivative, was combined with cefazolin, cephalexin, ampicillin, carbenicillin, ticarcillin, gentamicin, and trimethoprim. Synergy between fosmidomycin and penicillins or cephalosporins was found for 37 to 52% of the Enterobacteriaceae tested. Synergy with trimethoprim was found against 55% of bacteria isolated, but only 17% of the strains showed synergy between formidomycin and gentamicin. Synergy between fosmidomycin and ticarcillin was shown for 35% of the Pseudomonas isolates. Cefazolin-, ampicillin-, and gentamicin-resistant isolates of various species were synergistically inhibited by fosmidomycin, as were ticarcillin- and gentamicin-resistant isolates. Antagonism was not encountered. This study illustrates another example of synergistic activity of compounds which attack different mechanisms in bacterial cells.
磷霉素(FR - 31564),一种膦酸衍生物,与头孢唑林、头孢氨苄、氨苄西林、羧苄西林、替卡西林、庆大霉素和甲氧苄啶联合使用。在所测试的37%至52%的肠杆菌科细菌中发现磷霉素与青霉素或头孢菌素之间存在协同作用。发现与甲氧苄啶对55%的分离细菌有协同作用,但只有17%的菌株在磷霉素和庆大霉素之间表现出协同作用。在35%的铜绿假单胞菌分离株中显示出磷霉素与替卡西林之间的协同作用。各种物种对头孢唑林、氨苄西林和庆大霉素耐药的分离株以及对替卡西林和庆大霉素耐药的分离株均被磷霉素协同抑制。未发现拮抗作用。本研究说明了攻击细菌细胞中不同机制的化合物协同活性的另一个例子。
