<i>Penicillium</i> and <i>Talaromyces</i> diversity in cystic fibrosis patient sample and the description of a new species, <i>Penicillium subluteum</i> sp. nov. (Eurotiales, Aspergillaceae).

ABSTRACT: Penicillium and Talaromyces species are frequently isolated from the respiratory tracts of cystic fibrosis (CF) patients, yet their diversity, ecological roles, and clinical significance remain poorly understood. In this study, we analyzed 521 fungal isolates (482 Penicillium and 39 Talaromyces) obtained from Dutch CF patients to investigate species diversity and prevalence. Using a combination of AFLP fingerprinting and DNA sequences analysis, we identified 57 Penicillium and 18 Talaromyces species, including a putatively new species named Penicillium subluteum sp. nov. The most commonly isolated Penicillium species included P. crustosum, P. frequentans, P. chrysogenum, P. rubens, and P. brevicom
