New cystic fibrosis research takes aim at deadly pathogen

A new method of testing the most common cause of life-threatening infection in people with cystic fibrosis could improve efforts to study and combat the illness, researchers say. In cystic fibrosis, a serious genetic disease that causes recurring lung infections, bacteria colonize a patient's lungs, usually beginning in childhood, leading to difficulty breathing. One of the most dangerous of these bacteria is P. aeruginosa, which, within the unique mucus that forms in the lungs of a person with cystic fibrosis, develops into large, antibiotic-resistant colonies.
