Fungi are unicellular or multicellular heterotrophic eukaryotes that derive nutrition by absorption, reproduce by asexual or sexual means or both, and possess cell walls. Fungi are divided into 4 phyla based on their sexual structures (Ascomycota, Basidiomycota, Chytridiomycota, and Zygomycota). This chapter focuses on aspergillosis, followed by other fungal infections representing the less common mycoses. Aspergillosis is by far the most prevalent mycosis of birds and is an economically important respiratory disease of poultry. Candidiasis is the principal fungal infection of the digestive tract of poultry. Zygomycosis has similar signs and gross lesions to aspergillosis. Ochroconosis is uncommon in modern poultry production but is regionally significant. Macrorhabdosis is a recently described mycotic infection of the proventriculus/ventriculus of unknown significance in poultry. Histoplasmosis and cryptococcosis are rare fungal infections of poultry but are notable as public health hazards.
