In vitro activities of tritrpticin alone and in combination with other antimicrobial agents against Pseudomonas aeruginosa.
The in vitro activity of the cathelicidin tritrpticin was investigated against multidrug-resistant Pseudomonas aeruginosa. The isolates were susceptible to the peptide at concentrations of 0.50 to 8 mg/liter. Tritrpticin completely inhibits lipopolysaccharide procoagulant activity at a 10 microM concentration. Fractionary inhibitory concentration indexes (0.385, 0.312, and 0.458) demonstrated s...
متن کاملIn vitro and in vivo Pharmacodynamics of Colistin and Aztreonam Alone and in Combination against Multidrug-Resistant Pseudomonas aeruginosa.
BACKGROUND Reports of Pseudomonas aeruginosa with high antimicrobial resistance have steadily emerged, threatening the utility of a mainstay in antipseudomonal therapy. This study evaluated the antimicrobial activities of various combination therapies against P. aeruginosa with high antimicrobial resistance, including multidrug-resistant P. aeruginosa (MDRP) using an in vitro and in vivo study....

15 صفحه اولBL-P1654, ticarcillin, and carbenicillin: in vitro comparison alone and in combination with gentamicin against Pseudomonas aeruginosa.
Minimum inhibitory concentrations of carbenicillin, ticarcillin, and BL-P1654 were determined for 89 clinical isolates of Pseudomonas aeruginosa. Ticarcillin was generally twice as active and BL-P1654 eight to 16 times as active as carbenicillin. Usually carbenicillin and ticarcillin killed at the same concentration or twice the concentration needed to inhibit, whereas 400 mug of BL-P1654 per m...
متن کاملIn vitro activity of ceftriaxone alone and in combination with gentamicin, tobramycin, and amikacin against Pseudomonas aeruginosa.
The in vitro activity of ceftriaxone alone and in combination with gentamicin, tobramycin, and amikacin against 50 Pseudomonas aeruginosa strains was studied by the broth dilution method and the time-kill curve method. The majority of the P. aeruginosa strains tested were resistant to ceftriaxone. Combining ceftriaxone with the aminoglycosides resulted in synergism, antagonism, or indifference.
