Abstract
We studied the response ofEscherichia coli to ampicillin concentrations which decreased logarithmically at elimination half-life values (t 1/2a) ranging from one to four hours. The rate of bacterial killing depended on the initial antibiotic concentration (co), but was not significantly affected by t 1/2a. Irrespective of co and t 1/2a, the bactericidal effect terminated after about three hours of exposure to the drug. Untersucht wurde die Wirkkinetik aufEscherichia coli unter dem Einfluß von Ampicillin in logarithmisch abnehmenden Konzentrationen, bei Eliminations-Halbwertszeiten (t 1/2a) von ein bis vier Stunden. Die Bakterienabtötungsrate wurde von der Anfangskonzentration des Antibiotikums (co) beeinflußt, während t 1/2a keinen wesentlichen Einfluß hatte. Unabhängig von co und t 1/2a war der bakterizide Effekt auf eine Ampicillin-Expositionszeit von etwa drei Stunden begrenzt.This publication has 22 references indexed in Scilit:
