Is Scopulariopsis a dermatophyte?
In the UK, about 5% of fungal nail infections are caused by non-dermatophyte moulds. Scopulariopsis brevicaulis, a ubiquitous saprophyte of soil, is the most common, although other saprophytic moulds such as Fusarium, Aspergillus and Acremonium species are also occasionally implicated.
What causes tinea fungal infection?
Tinea is the name of a group of diseases caused by a fungus. Types of tinea include ringworm, athlete’s foot and jock itch. These infections are usually not serious, but they can be uncomfortable.

How do you treat candidal onychomycosis?
Oral Antifungal Agents for the Treatment of Onychomycosis
| Antifungal agent | Indication | Monitoring |
|---|---|---|
| Itraconazole (Sporanox) | Preferred therapy for nondermatophytic and candidal infections | None recommended |
| Fluconazole (Diflucan) | First-line therapy for candidal infections but also active against dermatophytes | None recommended |
What is the best treatment for tinea?

Which fungi causes dermatophytosis?
Anthropophilic dermatophytes, such as Trichophyton rubrum and Trichophyton tonsurans, are the main cause of human dermatophytosis.
What is the difference between Dermatophytosis and dermatomycosis?
A dermatomycosis is a skin disease caused by a fungus. This excludes dermatophytosis. Examples of dermatomycoses are tinea and cutaneous candidiasis. These fungal infections impair superficial layers of the skin, hair and nails.
How is dermatomycosis diagnosed?
Diagnosing dermatomycosis from a clinical image is not always easy. Microscopy of a potassium hydroxide preparation (KOH-test) and culturing are seldomly used in general practice. Cyanoacrylate surface skin scraping (CSSS) is a new diagnostic tool that may be useful and simple.
What is Scopulariopsis brevicaulis?
The most common of these is Scopulariopsis brevicaulis, which usually causes infection of the great toenails. Some patients with this form of infection have previously abnormal toenails (e.g., onychogryphosis).
What is the treatment for Scopulariopsis spp?
Oral antifungal therapy is unpredictable against these infections, 53 and nail removal with 40% urea is often used as an adjunctive treatment. Marcio Nucci, Elias J. Anaissie, in Clinical Mycology (Second Edition), 2009 Scopulariopsis spp. are frequently isolated from soil. The most common species are S. brevicaulis and S. brumptii.
What is tinea unguium (nail fungus)?
Onychomycosis (tinea unguium) is a fungal infection of the nail that is usually caused by infection with a dermatophyte, with Trichophyton rubrum accounting for the vast majority of cases (>70%). Less commonly, nondermatophytes including Candida spp. (≈10%), Scopulariopsis brevicaulis (≈10%), Fusarium spp., and others may produce disease.
What causes Scopulariopsis nail infection?
Scopulariopsis infections of the nails have a typical cinnamon color that is caused by the presence of fungal spores seen on direct microscopic views of the nail. The fungus is easy to isolate in culture. Treatment may be difficult, but chemical nail removal with 40% urea may be useful.
