Abstract
The postantibiotic effect (PAE) following three consecutive 2-h exposures to imipenem, temafloxacin, and tobramycin was determined in Pseudomonas aeruginosa. A PAE and a bactericidal effect were consistently observed for imipenem following each cycle of drug exposure and regrowth. In contrast, the PAE increased with repeated exposure with temafloxacin (1.8 to > 5 h), but disappeared with tobramycin by the third exposure (0.9 to 0 h). These data show that the in vitro PAE may change within a strain following multiple cycles of drug exposure and bacterial regrowth.
