Medical mycology is a branch of microbiology that focuses on the study of fungal infections in humans and animals. This includes the identification, diagnosis, and treatment of fungal diseases, as well as the study of the biology and pathogenesis of pathogenic fungi. Medical mycologists work to develop new antifungal drugs, improve diagnostic techniques, and understand the mechanisms of fungal infections in order to improve patient outcomes. Common fungal infections studied in medical mycology include candidiasis, aspergillosis, cryptococcosis, and dermatophytosis.
