After conidial size measurements, ploidy level was confirmed by benomyl susceptibility and fluorescence-activated cell sorting (FACS) analysis. Ploidy levels were based on benomyl susceptibility and FACS ratio results. If the two markers were not in agreement, inconclusive ploidy was concluded. Diploid isolates were only detected in the cystic fibrosis (CF) and chronic pulmonary aspergillosis (CPA) groups. No isolates with a conidial size ≥2.90 µm were detected in the acute invasive aspergillosis or environmental group.
