RESUMO
In vitro susceptibilities of 53 clinical isolates of Pseudomonas aeruginosa to nine antipseudomonal antibiotics were determined. From 96 to 100% of the isolates were susceptible to piperacillin, ticarcillin, and 1-oxacephalosporin (LY 127935). Of the aminoglycosides, 89, 82, 79, and 29% were susceptible to amikacin, tobramycin, gentamicin, and netilmicin, respectively. A total of 96% and 78% of the isolates were susceptible to 1-oxacephalosporin (LY127935) and cefotaxime, respectively, at concentrations of 62.5 micrograms/l. Supplementation of testing media by calcium and magnesium not only markedly increased the minimal inhibitory concentrations of the aminoglycosides, but also raised those of cefotaxime and the penicillins; no significant effect was noted with 1-oxace-phalosporin. Synergy was not demonstrated consistently in vitro with 1-oxace-phalosporin combined with either carbenicillin, ticarcillin, gentamicin, or tobramycin.
