Exoantigen test for the rapid identification of Exophiala spinifera.
Exophiala spinifera, one of the etiologic agents of subcutaneous phaeohyphomycosis, may be wrongly identified as Exophiala jeanselmei because of the morphologic similarity of the two species. A reagent containing a precipitin specific for E. spinifera was produced by absorbing antiserum to E. spinifera with E. jeanselmei serotype 1 antigen. Using this absorbed antiserum, we were able to correctly identify isolates of E. spinifera and differentiate them from those of Exophiala alcalophila, E. jeanselmei (serotypes 1, 2 and 3), Exophiala moniliae, Exophiala pisciphila, Exophiala salmonis, Phaeoannellomyces werneckii and Wangiella dermatitidis.
