What type of fungi is Dermatophyte?
Dermatophyte fungi are the ringworm fungi (tinea). They depend on their host, which may be an animal (“zoophilic”) or a human (“anthropophilic”) and need to spread from one host to another to survive. Dermatophytes may also prefer to live in the soil (“geophilic”).
What does a dermatophyte look like?
It typically presents with dry skin in the palms of the hands and a skin rash with inflamed, scaly borders on the back of the hand. Dermatophyte nail infections, or tinea unguium, can cause white or yellow discoloration of the nails, as well as either thickened or brittle nails.
Where do arthrospores form in the body?
Arthrospores are made up of fragments of the hyphae, breaking off at the septae. Asexual spores (conidia) form on conidiophores. The sexual reproductive phase of many fungi is unknown; these are fungi imperfecta. Superficial fungal infections affect the outer layers of the skin, the nails and hair.
What kind of fungi are involved in dermatophyte infections?
Most dermatophyte infections involve three genera of fungi: Trichophyton, Microsporum, and Epidermophyton. These fungi are found worldwide; infection is acquired from contact with affected humans or animals, or from exposure to contaminated soil or fomites (e.g., combs, brushes).
Are there sexual forms of the dermatophyte Arthroderma?
The single ascomycete genus Arthroderma accommodates the known sexual forms of all of the dermatophytes. 7 Even though the term dermatophytosis refers to an infection caused by a dermatophyte, not all dermatophytes may cause infection. The fungus colonizes the stratum corneum and then grows in a radial manner without penetrating viable tissue.
What’s the difference between Arthroderma and dermatomycosis8?
The term dermatomycosis8 differs in that it encompasses colonization and infection of keratinized tissue by fungi not classified in the genera Epidermophyton, Microsporum, and Trichophyton. In addition, when their sexual forms are known, they are classified in genera other than Arthroderma.
