Pathogenic fungi are fungi that cause disease in humans or other organisms. Although fungi are eukaryotic, many pathogenic fungi are microorganisms.[1] Approximately 300 fungi are known to be pathogenic to humans;[2] their study is called "medical mycology". Fungal infections are estimated to kill more people than either tuberculosis or malaria—about two million people per year.[3]
In 2022 the World Health Organization (WHO) published a list of fungal pathogens which should be a priority for public health action.[4]
Markedly more fungi are known to be pathogenic to plant life than those of the animal kingdom.[5] The study of fungi and other organisms pathogenic to plants is called plant pathology.
