Talaromyces marneffei is an important opportunistic human pathogen endemic to Southeast Asia. It is one of a number of pathogenic fungi that exhibits thermally controlled dimorphism. At 25°C, T. marneffei grows in a multicellular, filamentous hyphal form that can differentiate to produce dormant spores called conidia. These conidia are the likely infectious agent. At 37°C, T. marneffei grows as a uninucleate yeast that divides by fission. The yeast cells are the pathogenic form of this fungus. The protocols described here explain how to grow T. marneffei in the two vegetative growth forms in vitro, grow yeast cells inside mammalian macrophages, produce conidial stocks, and store strains both..
