Use: For the selective isolation of Burkholderia cepacia from the respiratory secretions of patients with cystic fibrosis and for routine testing of non-sterile inorganic salt solutions containing preservative. Slow growing B. cepacia can be missed on conventional media such as blood or MacConkey agar due to overgrowth caused by other faster growing organisms found in the respiratory tract of CF patients such as mucoid Klebsiella species, Pseudomonas aeruginosa, and Staphylo- coccus species. This may lead to the infection being missed or wrongly diagnosed.
