<prompt> The persistent suppression of bacterial growth that may occur after limited exposure to some antimicrobial drug is called:Time dependent killingPost antibiotic effectConcentration dependent killingSequential blockade  <response>: Ref: Katzung 10e p756 Time dependent killing kinetics is shown by aminoglycosides. Here, the killing activity depends upon thelength of time, plasma concentration is above MIC. Concentration dependent killing is shown by b lactam drugs. here, killing activity depends upon the ratio of plasma concentration to MIC. Post antibiotic effect is the suppression of bacterial growth after limit exposure to antibiotic.
