[Determination of the sensitivity of Pseudomonas aeruginosa to antibiotics using a synthetic liquid culture medium].

Antibiotic sensitivities of 120 Ps. aeruginosa strains isolated from patients and environmental objects have been studied by microdilutions in modified Jorgensen's liquid synthetic nutrient medium. Use of "transitional" concentrations of antibiotics permits a simultaneous examination of the sensitivities of 7-8 Ps. aeruginosa cultures to 6-11 antibiotics. The simplicity, low price, low consumption of nutrient medium, sufficient accuracy and good reproducibility of the results recommend this method for laboratory practice.
