High prevalence and genetic diversity of a single ancestral origin azole-resistant Aspergillus fumigatus in indoor environments at Walailak University, Southern Thailand.

This study explored the prevalence, genetic diversity, and population structure of azole-resistant Aspergillus fumigatus (ARAf) at Walailak University in Southern Thailand. Three hundred samples were collected from dwellings and workplaces, screened for azole resistance, and tested for drug susceptibility. Molecular detection of alterations in the cyp51A gene and CSP1 typing was performed.
