Currently there are no commercially available selective media indicated for the isolation of and . Ashdown’s agar, a custom selective medium for isolation of is well described in the literature but unavailable commercially. Three commercially available media, selective agar (BCSA), oxidative-fermentative-polymyxin B-bacitracin-lactose (OFPBL) agar, and (PC) agar are recommended for isolation of from respiratory secretions of cystic fibrosis patients. We evaluated the sensitivity and selectivity of these four media using 20 , 20 20 spp., and 15 diagnostically challenging organisms. Ashdown’s agar was the most sensitive medium for the isolation of , but it was unable to support growth of agar was highly sensitive and selective for both organisms. In non-endemic areas, we suggest the use of the commercially available PC agar for the isolation of .
