The Malthus-AT system provided a satisfactory method for examining the effects of permeabilizing agents on the activity of sub-inhibitory concentrations of antibacterial agents against Pseudomonas aeruginosa G48. Under this system, disodium edetate potentiated the activity of chlorhexidine diacetate (CHA), cetylpyridinium chloride, para-chlorometaxylenol and triclosan. Nitrilotriacetic acid enhanced the activity of some of the antibacterials tested, whereas sodium polyphosphate markedly reduced the efficacy of CHA.
