Early effects of beta-lactams on aminoglycoside uptake, bactericidal rates, and turbidimetrically measured growth inhibition in Pseudomonas aeruginosa.

چکیده
In vitro studies of tircarcillin or cefsulodin combined with [3H]tobramycin were performed with Pseudomonas aeruginosa. The rate of bacterial killing, the uptake of tobramycin, and the effects on optical density were measured. Both beta-lactams increased the uptake of subinhibitory concentrations of tobramycin. This result was quantitatively associated with a 2- to 4-h time-kill potentiation and confirmed earlier studies on the mechanism of beta-lactam-aminoglycoside synergy in Escherichia coli (P. H. Plotz and B. D. Davis, Science 135:1067-1068, 1962).

Involvement of the outer membrane in gentamicin and streptomycin uptake and killing in Pseudomonas aeruginosa.
Induction of a major outer membrane protein, H1, in Pseudomonas aeruginosa resulted in decreased susceptibility to gentamicin and streptomycin. Mutants which overproduce protein H1 and cells in which H1 is induced in response to growth conditions had altered kinetics of uptake and killing. It was further demonstrated that gentamicin and streptomycin interact with the outer membrane to permeabil...
متن کاملActivity of ciprofloxacin against multiply resistant strains of Pseudomonas aeruginosa, Staphylococcus epidermidis, and group JK corynebacteria.
The susceptibilities of multiply resistant clinical isolates of Pseudomonas aeurginosa to ciprofloxacin, norfloxacin, and several beta-lactam and aminoglycoside antibiotics were evaluated. Ciprofloxacin also was compared with methicillin and vancomycin against methicillin-resistant Staphylococcus epidermidis and group JK corynebacteria. Ciprofloxacin exhibited the lowest MICs and MBCs for 90% o...
متن کاملIn vitro antibacterial activities of antibiotics against Pseudomonas aeruginosa in peritoneal dialysis fluid.
Intraperitoneal antibiotics are used to treat Pseudomonas aeruginosa peritonitis, a serious complication of continuous ambulatory peritoneal dialysis. However, P. aeruginosa killing is often inefficient despite low MBCs. Broth dilution MIC/MBC and time kill curves of tobramycin, amikacin, netilmicin, azlocillin, piperacillin, ceftazidime, cefsulodin, and ciprofloxacin were determined in periton...
متن کاملComparison of the Effect of Phenylalanine Arginine Beta Naphthylamide (PAβN) and Curcumin on Minimum Inhibitory Concentration of Aminoglycosides on Pseudomonas aeruginosa Clinical Isolates
Background and Objective: Efflux pump inhibitors (EPIs) can block efflux pumps and are helpful in potentiating the activity of aminoglycosides against Pseudomonas aeruginosa. The present study compared the effects of phenylalanine-arginine beta naphthylamide (PAβN) and curcumin on aminoglycoside minimum inhibitory concentration (MIC) on Pseudomonas aeruginosa clinical isolates. Materials and M...

The in vitro activity of enoxacin (CI 919, AT 2266), a new oral quinolone carboxylic acid compound, was compared with those of gentamicin, tobramycin, amikacin, azlocillin, piperacillin, aztreonam, moxalactam, imipenem, cefsulodin, ceftazidime, and cefoperazone against 101 aminoglycoside-susceptible and 105 aminoglycoside-resistant Pseudomonas aeruginosa strains. Among these 206 P. aeruginosa i...
