Background: Respiratory infections are a major threat for lung recipients. We aimed to compare with a\nmonocentric study the impact of late viral and bacterial respiratory infections on the graft function.\nMethods: Patients, who survived 6 months or more following lung transplantation that took place between 2009\nand 2014, were classified into three groups: a viral infection group (VIG) (without any respiratory bacteria), a\nbacterial infection group (BIG) (with or without any respiratory viruses), and a control group (CG) (no documented\ninfection). Chronic lung allograft dysfunction (CLAD) and acute rejection were analysed 6 months after the inclusion\nin the study.\nResults: Among 99 included lung recipients, 57 (58%) had at least one positive virological respiratory sample\nduring the study period. Patients were classified as follows: 38 in the VIG, 25 in the BIG (among which 19 coinfections\nwith a virus) and 36 in the CG. The BIG presented a higher initial deterioration in lung function................................
