Study Notes
Fungal Infections: Classification
- Fungal infections are categorized by the tissues or organs they primarily colonize.
- Superficial infections affect only the outermost layers of skin (stratum corneum) or hair (cuticle).
- Dermatophyte infections affect skin, hair, and nails, involving fungi that colonize the living host.
- Subcutaneous mycoses are caused by fungi prevalent in the environment; these have a relatively low ability to cause infection.
- Systemic mycoses can infect humans and animals. They primarily enter through the respiratory system.

Description
Overview of the classification of fungal infections based on the tissues or organs they colonize. Categories include superficial infections, dermatophyte infections, subcutaneous mycoses, and systemic mycoses. Focus on how these infections affect different parts of the body.
