In vitro antibacterial activity of amikacin and ticarcillin, alone and in combination, against Pseudomonas aerurginosa.

In vitro antimicrobial susceptibility studies using amikacin and ticarcillin, alone and in combination, were performed on 20 strains of Pseudomonas aeruginosa. All strains were susceptible to amikacin, and ticarcillin was active against 16 of the 20 strains. Enhanced anti-pseudomonas activity could be demonstrated with the combination of amikacin and ticarcillin.
