Predatory Bacteria Found in Study of Cystic Fibrosis Patients’ Lung Microbiome.

Cystic fibrosis patients have a wide variety of bacteria in their lungs, including two ‘predators’ not detected before, according to a new study of lung microorganisms published this week in mBio®, an open-access journal of the American Society for Microbiology.

Using a laboratory technique called next-generation sequencing, a group of investigators from Madrid, Spain, studied the bacterial makeup of sputum samples provided by 15 cystic fibrosis patients three to four times over the course of a year. They found a wide range of bacterial species in the samples, including Pseudomonas aeruginosa, Staphylococcus aureus, Burkholderia and Pandorea. Each patient had his or her own bacterial makeup that remained relatively steady over the study period.
