Among people with bronchiectasis, those more than 55 years old or who have bronchiectasis as a result of infection, are at an increased risk of being colonized with the bacteria Pseudomonas aeruginosa.
The human body is home for many different kinds of bacteria; most are benign, but some cause health problems. It’s known that people with bronchiectasis who have P. aeruginosa infection in their lungs are at increased risk of frequent exacerbations and more hospital stays.
