Abstract
A new selective agar medium (CKNA), containing cetrimide 0.3 g/l, kanamycin sulfate 50 mg/l, and nalidixic acid 5 mg/l, was developed for the isolation of Pseudomonas aeruginosa. It was compared to Nalidixic Acid Cetrimide agar (NAC), Pseudomonas Aeruginosa Selective Agar (PASA) and Pseudosel^TM^ agar (CET) using 1,148 clinical specimens. The sensitivities rates of P. aeruginosa with CKNA, NAC, PASA, and CET were 88.2%, 81.3%, 79.2%, and 84.0%, respectively. The specificities of CKNA, NAC, PASA, and CET were 99.2%, 98.4%, 99.2%, and 99.7%, respectively.
