Exophiala

(ek'sō-fī'ă-lă),
A genus of pathogenic fungi having dematiaceous conidiophores with one- or two-celled annelloconidia. They cause mycetoma or phaeohyphomycosis; in cases of mycetoma, black granules develop in subcutaneous abscesses; in cases of phaeohyphomycosis, hyaline or brownish hyphae are found in tissues.
[exo + G. phialē, a broad flat vessel]

Exophiala

/Exo·phi·a·la/ (-fi´ah-lah) a genus of saprobic fungi; E. wernec´kii is now called Hortaea werneckii.

Exophiala

[ek′sofī′ə·lə]
a widespread genus of saprobic Fungi Imperfecti. E. jeanselmei is commonly found in soil and sewage and causes mycetoma and opportunistic infections in humans. Hortae werneckii (formerly classified as E. werneckii) is the cause of tinea nigra. Because it is so variable, some authorities have proposed dividing it into more than one species. Infection usually results from traumatic implantation and is associated with local or systemic immunosuppression.

Exophiala

A genus of imperfect fungus with no known sexual state. Colonies are initially yeast-like, moist, and brownish to greenish black. The texture becomes velvety due to short, aerial hyphae. The front colour is olive-black; the reverse is black in mature colonies. Exophiala may cause mycetoma and chromoblastomycosis after traumatic subcutaneous inoculation in a background of local or systemic immunosuppression, such as organ transplantation. Other sources of infection include prosthetic valve vegetations, fungemia and systemic infection.

Ex·o·phi·a·la

(eks'ō-fī-ā'la)
A genus of pathogenic fungi having dematiaceous conidiophores. They cause mycetoma or phaeohyphomycosis; in cases of mycetoma, black granules develop in subcutaneous abscesses; in cases of phaeohyphomycosis, sclerotic bodies are found in tissues.

Exophiala

a genus of dematiaceous fungi that cause mycetomas and pheohyphomycosis including cutaneous and systemic lesions, in fish and captive frogs and toads. Includes E. pisciphilia, E. salmonis.

It has been observed that in the industrial environment where a lot of pigeons, sparrows and other birds fly most often thrush fungi are detected: Candida albicans (M-1; R-21; I-32%); Rhodotorula rubra (M-6; R 10; I-23%); Exophiala jeanselmei (M-2; R-6; I 17%), Asperlillus fumigatus (M-6; R-13; I-49%) and Eurotium repens (M-3; R-11; I-23%).
They found that about 33 percent of the samples tested positive for fungi, with the common one being Exophiala dermatitidis and phaeomuriformis, two types of black yeast, and dishwashers the most likely location where they were breeding.
At least 20 species from 11 genera are implicated including Bipolaris, Curvularia, and Exophiala.
2) The most commonly isolated fungi were Exophiala species, which can colonize the lungs of patients with cystic fibrosis and occasionally cause fatal infections in healthy humans; these were found in over half the dishwashers sampled.
Posaconazole has shown promise in the treatment of invasive fusariosis, Scedosporium apiospermum infections, disseminated phaeohyphomycosis due to Exophiala spinifera, and refractory coccidioidomycosis infections (36-40).
These typically manifest as subcutaneous nodules appearing after minor trauma to the skin and inoculation with species of Exophiala, Alternaria, or Phialophora.
