Characterization of Clinical Isolates of Talaromyces marneffei and Related Species, California, USA

Abstract

Talaromyces marneffei and other Talaromyces species can cause opportunistic invasive fungal infections. We characterized clinical Talaromyces isolates from patients in California, USA, a non–Talaromyces-endemic area, by a multiphasic approach, including multigene phylogeny, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, and phenotypic methods. We identified 10 potentially pathogenic Talaromyces isolates, 2 T. marneffei.
