Abstract
The administration separately and sequentially of carbenicillin and gentamicin eradicated Ps. aeruginosa infections, during the period over which they were given, in all of 25 critically ill patients. Electron microscopy revealed differences in the action of these two antibiotics against Ps. aeruginosa in vitro. Culture studies showed synergism between them and destruction by gentamicin of the carbenicillin-induced long, filamentous form of the organism.
