Genotypic relationship among Aspergillus fumigatus isolates from patient 33 (described in this case report, in red), isolates from patient 12, and the resistant isolate, already published, from patient 32 (LIF 2444-6 and LIF 2552-4.9) [6]. The dendrogram is based on a categorical analysis of nine microsatellite markers in combination with the arithmetic mean unweighted pair group clustering method (UPGMA) using Phyloviz 2.0a.
