Enhanced recovery of Pseudomonas aeruginosa from diverse clinical specimens on a new selective agar

A new agent, 9-chloro-9-(diethylaminophenyl)-10-phenylacridan (C-390), was compared to currently available selective agars for the recovery of Pseudomonas aeruginosa. Media containing C-390 were highly selective for P. aeruginosa and enhanced recovery of the organism from clinical specimens because of the low background level of contaminating microorganisms.
