“…Cystic fibrosis (CF) is the most common monogenetic autosomal recessive disease in Northern Europe. The disease is caused by mutations in a cystic fibrosis transmembrane conductance regulator (CFTR) gene whose product is a chloride channel (Williams et al [ 1 ]). CFTR mutations result in reduced excretion of chloride ions in the apical membrane of epithelial cells.…”

“…The colonization of the lower respiratory tract with microorganisms progresses with the duration of cystic fibrosis. In the early phases, the most common bacteria are Staphylococcus aureus and Haemophilus influenzae , whereas a wide range of bacteria, mainly Pseudomonas aeruginosa , Burkholderia cepacia complex, and other Gram-negative bacteria as well as fungal species, are isolated in the later stages of the disease [ 1 ]. There are several studies analyzing the prevalence of the pathogenic bacteria and fungi in patients with CF (for recent reviews, see [ 3 – 5 ]).…”

Cystic fibrosis (CF) patients become colonized by pathogenic bacteria as well as by Candida species. The interplay between different microorganisms may play a key role in the prognosis of CF. The aim of the study was to analyze the coexistence patterns of bacteria and Candida spp. in sputum samples of patients with CF and to compare these patterns with the results of patients with other respiratory disorders (ORD). Sputum samples from 130 patients with CF and 186 patients with ORD were cultured on six different agar plates promoting the growth of bacteria and yeasts. Bacterial and Candida species were identified with MALDI-TOF MS. Pathogenic bacteria were found in 69.2% of the sputum samples of the CF patients, and in 44.1% the patients with ORD. CF patients tended to have growth of Pseudomonas aeruginosa and Staphylococcus aureus in sputum more often than patients with ORD. Overall, there was no difference in the coexistence of pathogenic bacteria and Candida spp. in these patient groups. However, when analyzed at the species level, P. aeruginosa and S. aureus coexisted with Candida spp. more frequently in sputum samples of CF patients compared with patients with ORD. Also, when analyzed according to age, it was shown that the adult (≥ 18 years) CF patients had a higher rate of coexistence of any pathogenic bacteria and Candida spp. than the children with CF and the adult patients with ORD. The rate for colonization with Candida together with pathogenic bacteria is increased in adult patients with CF.

Metagenomic studies have also revealed an impact of respiratory viral infections in CF airway damage [21][22][23], as well as the presence of bacterial viruses (phages) in CF airways [24,25].…”

“…However, as the disease progresses, the lung microbiome of patients with CF is dominated by the bacterium Pseudomonas aeruginosa [33]. Some recent studies have reported that co-colonisation of the airways by C. albicans or A. fumigatus with P. aeruginosa lead to more exacerbations and decreased lung function [34,35]. Other fungal species frequently detected in the airways from patients with CF include Penicillium species, nonfumigatus Aspergillus species, Scedosporium, Exophiala Fig.…”

Purpose of the Review This review summarises the characteristics of the lung mycobiome in patients with chronic respiratory diseases and fungal lung diseases. We have also reviewed the limitations of the current methods in mycobiome studies. Recent Findings Available studies in the impacts of the mycobiome in chronic and fungal lung diseases are scarce and comparison of the available studies is hindered by heterogeneity in the sample sizes, methods and patient selection. Summary The impact of the diversity and composition of the lung mycobiome in chronic and fungal lung diseases is poorly understood. Most studies involve detection of fungi in respiratory samples by culture. However, such methods lack sensitivity and the emergence of next-generation sequencing technologies is an important advance. However, differences in the sequencing methodologies limit study comparisons. Well-designed methodological approaches and large cohort studies are needed to evaluate the impact of the lung mycobiome in respiratory diseases.
