a and b Dynamics of lung function and anti-P. aeruginosa antibody values over time in two identical twins from the intermittently infected group. P. aeruginosa had been last isolated from their sputum 2 years before inclusion in the study. Eradication therapy had been completed and was considered successful at that time according to the guidelines [25]. Isolation of P. aeruginosa, aggravation of lung function and a rise in anti-P. aeruginosa antibodies was observed a year apart in the two twins. P. aeruginosa had been further intermittently isolated in both patients after the end of the study
