Over their life time, CF patients experience multiple infections by various pneumoniacausing bacteria [6]. With more patients surviving to adulthood, chronic infections with Pseudomonas aeruginosa are coming to the forefront as a leading cause of death [7]. Problems presented by infected CF lung are multi-dimensional; the electrolyte balance and pH of the fluids are abnormal. The mucus is thick and of an alternative composition compared to normal lung and may contribute to colonization with Pseudomonas aeruginosa [2, 3, 5]. As such, research is multi-pronged and includes gene therapy to correct the defective protein, amelioration of inflammatory response and thinning of alveolar surface fluids [8, 9]. Significantly, Pseudomonas bacteria colonize the CF lung far easier than normal lung. Normal lung tissue has several naturally occurring defenses that work in concert with commonly prescribed antibiotics for recovery from lung infections [4, 10]. The CF patient appears to lack these natural defenses [1, 7].https://digitalcommons.chapman.edu/pharmacy_books/1009/thumbnail.jp
