Quality control limits for ampicillin, carbenicillin, mezlocillin, and piperacillin disk diffusion susceptibility tests: a collaborative study.
A multilaboratory in vitro study was carried out to determine disk diffusion susceptibility testing quality control limits for two new semisynthetic penicillins, mezlocillin and piperacillin. Existing limits for carbenicillin and ampicillin were reevaluated. Multiple tests (which followed standards set by the National Committee for Clinical Laboratory Standards ASM-2 revised) were performed in ...
متن کاملMezlocillin susceptibility tests by the single-disk agar diffusion method.
A regression line for correlating zones of inhibition of a 75-mug mezlocillin disk with minimal inhibitory concentrations of mezlocillin for Enterobacteriaceae and nonfermenters was calculated. Correlation was excellent (r = -0.96) for all species tested except Pseudomonas cepacia.
متن کاملTobramycin inactivation by carbenicillin, ticarcillin, and piperacillin.
The in vitro and in vivo inactivation of tobramycin by carbenicillin, ticarcillin, or piperacillin was investigated by the enzyme immunoassay method in clinically employed dosages. After the addition of an 80-mg dose of tobramycin to 4- to 5-g doses of a penicillin in 100 ml of 0.9% saline or distilled water, the degradation profile of tobramycin appeared to follow a biexponential pattern of de...
متن کاملThe comparative synergistic activity of amikacin, gentamicin, netilmicin and azlocillin, mezlocillin, carbenicillin and ticarcillin against Serratia marcescens.
The synergistic activities of netilmicin, gentamicin and amikacin combined with carbenicillin, ticarcillin, azlocillin and mezlocillin were investigated against 32 Serratia marcescens isolates. Synergy could be demonstrated by killing curve technique, isobologram plots as susceptibility data with any of the aminoglycosides and penicillins combinations. No antagonism was shown with any of the co...
متن کاملComparative study of piperacillin, ticarcillin, and carbenicillin pharmacokinetics.
Piperacillin, ticarcillin, and carbenicillin were administered intravenously to 10 healthy volunteers in a three-way, crossover study. The pharmacokinetics of the three drugs were in general quite similar. The peak serum concentration of piperacillin achieved at the end of a 30-min intravenous infusion was 63.5 +/- 27.6 microgram/ml. During the first 8 h, 67.5% of the dose of piperacillin was e...
