- Any infection due to a fungus of the zygomycota phylum. The disease typically involves the rhino-facial-cranial area, lungs, gastrointestinal tract, skin, or less commonly other organ systems. The infecting fungi have a predilection for invading vessels of the arterial system, causing embolization and subsequent necrosis of surrounding tissue.
- Infection in humans and animals caused by fungi in the class zygomycetes. It includes mucormycosis and entomophthoramycosis. The latter is a tropical infection of subcutaneous tissue or paranasal sinuses caused by fungi in the order entomophthorales. Phycomycosis, closely related to zygomycosis, describes infection with members of phycomycetes, an obsolete classification.
