For patients with cystic fibrosis Pseudomonas aeruginosa infection is a major contributor to progressive lung disease.
Pseudomonas aeruginosa can be transmitted between siblings and patient-to-patient transmission can occur in clinical settings and in camps for children with cystic fibrosis. However, initial infections are frequently found to be genetically more similar to strains collected from environmental sources than those from chronically-infected cystic fibrosis patients. This indicates that the source of these initial infections is likely to be in the patients’ everyday environment. Research has shown that household drains can be one source of Pseudomonas aeruginosa (M.E. Purdy-Gibson et al., 2015).
