Special Info

Selective media are used to optimize recovery of aerobic bacteria associated with infection in cystic fibrosis lungs including Staphylococcus aureus, Pseudomonas aeruginosa, Burkholderia cepacia complex, Stenotrophomonas maltophilia, Haemophilus influenzae, and other gram-negative bacilli. Identification of B. cepacia complex species is characterized by molecular testing performed at the B. cepacia Research Laboratory and Repository. Separate test orders are required to rule out the presence of mycobacteria, fungi, viruses, and atypical bacterial pathogens.

Clinical Info

Susceptibility testing is performed on potential pathogens in significant amounts (typically defined as moderate growth in sputum or tracheal aspirate specimens that is greater than normal background respiratory microbiota).
