Abstract
Striking bacterial activity against Pseudomonas aeruginosa 9D-2 was achieved by glycine-carbenicillin, ethylenediaminetetraacetic acid-carbenicillin, and glycine-ethylenediaminetetraacetic acid combinations, whereas none of the agents used alone was capable of the same degree of bactericidal activity. Studies using a microtiter modification of the checkerboard technique were performed to evaluate the comparative activity of these antimicrobial combinations. Isobolograms showed synergistic effects with carbenicillin-glycine, carbenicillin-ethylene-diaminetetraacetic acid, and glycine-ethylenediaminetetraacetic acid combinations. Bacterial growth inhibitory curves with subinhibitory concentrations of these agents in combination confirmed these findings.
