Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Syed Hassan A. Kazmi BSc, MD [2]
Overview
Overview
Dermatophytes may be classified according to genera, mode of transmission and disease patterns. Dermatophytes of the genera Trichophyton and Microsporum are the most common causative agents.
Classification
Classification
Dermatophytes may be classified according to various schemes.[1][2]
Classification based on genera
Based upon their genera, dermatophytes can be classified into three groups:
- Trichophyton (which causes infections of the skin, hair, and nails)
- Epidermophyton (which causes infections of the skin and nails)
- Microsporum (which causes infections of the skin and hair)
Classification based on mode of transmission
Based upon mode of transmission, these have been classified as:
| Anthrophilic species | Zoophilic species | Geophilic species |
|---|---|---|
| E. floccossum | M. canis | E. stockdaleae |
| M. audouinii | M. equinum | M. amazonicum |
| M. concentricum | T. gallinae | Microsporum anamorph of A. cookiellum |
| T. gourvilli | M. persicolor | M. boullandii |
| T. kanei | T. equinum | M. cookei |
| T. meginii | T. mentagrophytes | M. gypseum |
| T. mentagrophytes | T. sarkisorii | M. nanum |
| T. raubitsschekii | T. simii | M. praecox |
| T. rubrum | T. verrucosum | M. racemosum |
| T. schoenleinii | M. ripariae | |
| T. soudanese | M. vanbreuseghemii | |
| T. tonsurans | T. ajelloi | |
| T. violaceum | T. flavescens | |
| T. yaoundei | T. longifusum | |
| T. gloriae | ||
| T. phaseoliforme | ||
| T. vanbreuseghemii | ||
| T. terrestre |
Classification based on disease patterns
Dermatophytosis may be classified into the following types based on disease patterns:
- Tinea pedis (athlete’s foot) affects the feet
- Tinea unguium affects the fingernails and toenails
- Tinea corporis affects the arms, legs, and trunk
- Tinea cruris (jock itch) affects the groin area
- Tinea manuum affects the hands and palm area
- Tinea capitis affects the scalp
- Tinea barbae affects facial hair
- Tinea faciei (face fungus) affects the face
