Molecular epidemiology of Aspergillus species and other moulds in respiratory samples from Argentinean patients with cystic fibrosis

Abstract: In cystic fibrosis (CF) patients, fungal colonization of the respiratory tract is frequently found. Aspergillus fumigatus is the most frequently recorded and is associated with loss of pulmonary function and allergic disease (ABPA). The knowledge on prevalence rates of filamentous fungi in CF patients in Latin America is scarce. One hundred and seventy-six fungal isolates recovered from the upper respiratory tract of CF patients from Argentina were identified to species by morphology and DNA sequencing. In tot… Show more

“…All sputum samples were processed using %5 N‐acetyl‐ l ‐cysteine at a 1:1 ratio for liquefying and then subsequently plated undiluted on culture media. Culture media for fungi included Sabouraud dextrose agar (SDA) supplemented with 500 mg/L chloramphenicol and selective media such as the Scedosporium ‐agar (SceSel+‐agar), the erythritol‐chloramphenicol agar (ECA) and the Remel inhibitory mould agar (IMA), as previously described 2 . All plates were incubated at 37°C for at least 10 days at 37°C.…”

“…Aspergillus fumigatus is the most frequently filamentous fungi recovered from the respiratory secretions of patients with cystic fibrosis (CF) 1,2 . A. fumigatus can cause several pulmonary manifestations in CF patients, including allergic bronchopulmonary aspergillosis (ABPA) and bronchitis 3 .…”

“…Here, we identified Aspergillus isolates obtained from indoor and outdoor housing environments in Havana, Cuba, belonging to the following sections: Versicolores, Usti, Flavi, Aspergillus, Cremei, Fumigati, Clavati, Nigri, Candidi, Flavipedes, and Circumdati. Of these, species from the sections Fumigati, Flavi, and Nigri may cause allergic diseases [40]; they were also found to be the most abundant.…”

“…The most common forms of deep infections are respiratory system infections, due to inhalation, and pulmonary infections; the latter are mostly not invasive, but it seems likely that subclinical colonization may be involved in Europe or Latin America, as rates can vary from 1% to 19%[ 3 , 16 , 25 , 30 ]. This pathogen is known to cause deep or localized phaeohyphomycosis in immunocompromised people worldwide, and is regularly found in the lungs of cystic fibrosis (CF) patients, but only very rarely is it found in respiratory specimens from patients who do not suffer from CF[ 2 , 18 , 31 ].…”
