Evaluation of a New Culture Protocol for Enhancing Fungal Detection Rates in Respiratory Samples of Cystic Fibrosis Patients.

Cystic fibrosis (CF) can be complicated by fungal infection of the respiratory tract. Fungal detection rates in CF sputa are highly dependent on the culture protocol and incubation conditions and thus may lead to an underestimation of the true prevalence of fungal colonization. We conducted a prospective study to evaluate the additional value of mucolytic pre-treatment, increased inoculum (100 µL), additional fungal culture media (Sabouraud agar; SAB, Medium B+, selective agar; SceSel+ and Dichloran-Glycerol agar; DG18) and longer incubation time (3 weeks) compared with our current protocol.

Aerosol Transmission of Aspergillus fumigatus in Cystic Fibrosis Patients in the Netherlands.

We collected sputum samples and cough plates from 15 cystic fibrosis patients in the Netherlands who were colonized with Aspergillus fumigatus; we recovered A. fumigatus of the same genotype in cough aerosols and sputum samples from 2 patients. The belief that transmission of A.

Prevalence and diversity of filamentous fungi in the airways of cystic fibrosis patients - A Dutch, multicentre study.

Background: Progressive lung injury in Cystic Fibrosis (CF) patients can lead to chronic colonization with bacteria and fungi. Fungal colonization is obtained from the environment which necessitates locally performed epidemiology studies. We prospectively analyzed respiratory samples of CF patients during a 3-year period, using a uniform fungal culture protocol, focusing on filamentous fungi and azole resistance in Aspergillus fumigatus.
