Infections by dematiaceous fungi especially phaeohyphomycosis are an emerging group of infectious diseases worldwide with a variety of clinical presentations. The mouse model is a useful tool for studying phaeohyphomycosis, which can mimic dematiaceous fungal infections in humans. Our laboratory has successfully constructed a mouse model of subcutaneous phaeohyphomycosis and found significant phenotypic differences between Card9 knockout and wild-type mice, mirroring the increased susceptibility to this infection observed in CARD9-deficient humans. Here we describe construction of the mouse model of subcutaneous phaeohyphomycosis and related experiments. We hope that this chapter can be beneficial for the study of phaeohyphomycosis and facilitate the development of new diagnostic and therapeutic approaches.
