Microsatellite (STRAf) Genotyping Cannot Differentiate between Invasive and Colonizing Aspergillus fumigatus Isolates

摘要

We studied whether short tandem repeats of Aspergillus fumigatus (STRAf) can differentiate between invasive and colonizing genotypes of A. fumigatus. Of the 395 genotypes detected (n = 1,373 isolates), 50 were clusters and 24 (6% of all genotypes) involved the patients with invasive aspergillosis and those colonized with A. fumigatus, indicating that genotyping cannot discriminate between invasive and colonizing isolates.
