A cystic fibrosis child with lung function decline

Abstract Respiratory infections are a major threat to cystic fibrosis patients. Besides bacteria, many fungi colonize the cystic fibrosis respiratory tract where an important fungal biota has been described. We report here the case of a 7-year-old cystic fibrosis child with pulmonary exacerbation and Arthrographis kalrae isolated from bronchoalveolar lavage fluid. To the best of our knowledge, this is the first reported case of lung infection due to Arhtrographis kalrae in a cystic fibrosis pediatric patient.
