Growth ofPseudomonas aeruginosa and thirty-five other species of gramnegative bacilli was observed on 0.03% cetrimide in heart infusion agar medium and Pseudosel agar (BBL). The 0.03% cetrimide agar was more selective for growth ofP. aeruginosa than was Pseudosel agar; however, certain bacteria other thanP. aeruginosa also grew on the former medium. Although Pseudosel agar was not a highly selective medium forP. aeruginosa , it was preferable to technicolor agar for detection of the pyocyanin and pyorubin pigments produced byP. aeruginosa .
