Definitions and main characteristics
Start with the big picture
Fungal structure and growth provide a foundation for recognizing medically important organisms. Yeasts are unicellular and commonly reproduce by budding or fission, whereas molds grow as hyphae that form a mycelium. Hyphal septation and branching can aid identification, and some fungi are thermally dimorphic. Fungi reproduce through spores or conidia, with asexual and sexual states described as anamorph and teleomorph. Their clinical importance ranges from superficial disease to systemic infection, including disease in immunocompromised hosts. The broader topic also connects fungal biology to virulence, host defenses, laboratory diagnosis, antifungal therapy, epidemiology, and taxonomy.
What you'll learn
- Describe key fungal cell wall and membrane features.
- Distinguish yeasts, molds, and pseudohyphae by morphology.
- Explain the terms hypha, mycelium, anamorph, and teleomorph.
- Recognize how fungal growth forms relate to identification and disease.
