Common antigens among systemic disease fungi analyzed by two-dimensional immunoelectrophoresis. 1979

M Huppert, and J P Adler, and E H Rice, and S H Sun

The interpretation of immunological results in systemic mycoses has been complicated by cross-reactions among specimens from patients with blastomycosis, coccidioidomycosis, and histoplasmosis. The fungal preparations used in these tests evidently contained one or more antigens in common. Two-dimensional immunoelectrophoresis techniques were used to determine the number of antigens contained in several soluble extracts from Blastomyces dermatitidis and Histoplasma capsulatum that were common with those demonstrable in a coccidiodin-anticoccidioidin reference system. A total of 12 and 10 common antigens were found in preparations from B. dermatitidis and H. capsulatum, respectively. In addition, the crude preparations from each species of fungus exhibited some qualitative and quantitative differences in composition of antigens. Use of two-dimensional immunoelectrophoresis for standardization of fungus extracts, for monitoring separation of species-specific antigens, and for testing humoral antibody response should add further refinement to correlations with clinical disease.

UI MeSH Term Description Entries
D007122 Immunoelectrophoresis A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D001758 Blastomyces A genus of onygenacetous mitosporic fungi whose perfect state is Ajellomyces (see ONYGENALES). The species Blastomyces dermatitidis (perfect state is Ajellomyces dermatitidis) causes blastomycosis. Ajellomyces dermatitidis,Blastomycoides dermatitidis,Blastomyces dermatitidis
D003045 Coccidioides A mitosporic fungal genus which causes COCCIDIOIDOMYCOSIS. Coccidioides immitis
D003046 Coccidioidin A sterile solution containing the by-products of growth products of COCCIDIOIDES IMMITIS, injected intracutaneously as a test for COCCIDIOIDOMYCOSIS.
D006658 Histoplasma A mitosporic Onygenales fungal genus causing HISTOPLASMOSIS in humans and animals. Its single species is Histoplasma capsulatum which has two varieties: H. capsulatum var. capsulatum and H. capsulatum var. duboisii. Its teleomorph is AJELLOMYCES capsulatus. Ajellomyces capsulatus,Cryptococcus capsulatus,Emmonsiella capsulata,Histoplasma capsulatum,Histoplasmas
D000946 Antigens, Fungal Substances of fungal origin that have antigenic activity. Fungal Antigen,Fungal Antigens,Antigen, Fungal
