Description of intervention(s) / exposure
This project is divided into four parts. Part one is designed to examine whether early acquisition of P.aeruginosa in young children with CF is associated with environmental sources of P.aeruginosa in the home. Part two is a methodology study designed to screen large numbers of microbiological samples for the predominant Brisbane clonal strain of P.aeruginosa. Part three allows an opportunity to explore the possible relationship between molecular factors that may be involved in acquisition and transmission of clonal strains of P.aeruginosa. Part four examines culturable cough generated aerosols in patients with CF and an examination of clinical factors that may be involved in aerosol transmission of P.aeruginosa. It is anticipated that environmental sampling may take up to 2 years to complete and that clinical air sampling will take up to 12 months to complete.

Outcomes
Primary outcome [1] 1068 0
To identify if aerosol contamination in the home environment provides the most likely source of P.aeruginosa for initial infection with P. aeruginosa
Timepoint [1] 1068 0
At time of testing
Primary outcome [2] 1069 0
To determine if transmission of P. aeruginosa is related to exposure time and infective load of aerosolised P. aeruginosa and specific virulence factors associated with the organism.
Timepoint [2] 1069 0
At time of testing
Secondary outcome [1] 1982 0
To provide practical solutions that will contain the risks of cross-infection and enable appropriate and optimal management of all patients with CF.

Summary
Brief summary
This study has been designed to examine where first infections with Pseudomonas aeruginosa come from and also to examine the factors that may be important in how the organism might be passed from one person to another with CF.
