Taxonomic Classification

• Domain Eukarya (Cells have true nuclei)
• Kingdom Mycetae (Fungae) ie. Fungi
• Phylum
• Zygomycota
• Ascomycota
• Basidiomycota
• Deutermycota (Anamorphs)

Teleomorphs and Anamorphs
Teleomorphs sexual form (perfect
state) Anamorphs asexual form (imperfect
state)

Taxonomic Classification

• Characteristics of Zygomycota
• Reproduce sexually (teleomorphic form) by
  zygospores
• Reproduce asexually (anamorphic form) by
  sporangiospores that develop within a sporangium
• Possess hyphae that rarely produce septae
  (partially or non-septate or coenocytic)
• Uncommon cause of human mycoses
• Mostly environmental saprophytes (e.g. bread
  molds)

Taxonomic Classification

• Characteristics of Zygomycota
• Mostly opportunistic pathogens
• Clinical infection known as zygomycosis
  (singular) or zygomycoses (plural)
