Use of the exoantigen test to identify blastomyces dermatitidis, coccidioides immitis, and Histoplasma capsulatum in mixed cultures. 1981

A F DiSalvo, and A A Terreni, and A K Wooten

Cultures of Blastomyces dermatitidis, Coccidioides immitis, and Histoplasma capsulatum were inoculated with each of five saprophytes to simulate contaminated cultures. The cultures were extracted and tested in the immunodiffusion exoantigen test. Twenty-nine of 30 cultures were correctly identified. The saprophytes did not appear to interfere with the exoantigen test.

D003470 Culture Media Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN. Media, Culture
