This resistance is often linked to the use of agricultural fungicides and is primarily caused by tandem repeats (TRs) in the\n                      <jats:italic toggle=\"yes\">cyp51A<\/jats:italic>\n                      promoter, along with mutations in the coding region, leading to pan-azole resistance.

To further investigate the persistence of these resistant strains, soil samples were collected over three time periods. Whole genome sequencing was performed on isolates from each sampling date, and results were compared to publicly available isolates using phylogenetic, principal component, and ADMIXTURE analyses. These findings demonstrated that the same strains of TR-based azole-resistant\n                      <jats:italic toggle=\"yes\">A. fumigatus<\/jats:italic>\n                      persisted in the same environmental hotspot over time. Additionally, we observed high levels of recombination between different clades, which may contribute to the ongoing presence of\n                      <jats:italic toggle=\"yes\">A. fumigatus<\/jats:italic>\n                      in the United States. These findings highlight the environmental persistence of azole-resistant strains and underscore the need for monitoring antifungal resistance in environmental settings to better understand its potential clinical implications.\n                    <\/jats:p>\n                    <jats:sec>\n                      <jats:title>IMPORTANCE<\/jats:title>\n                      <jats:p>\n                        <jats:italic toggle=\"yes\">Aspergillus fumigatus<\/jats:italic>\n                        is a fungal pathogen that poses a substantial threat to humans, particularly in high-risk populations, with mortality rates reaching 90%.
