title: Agar-gel precipitin-inhibition test for coccidioidomycosis. II. Serological test antigen studies in agar-gel.
abstract: In this study of saprophytic and parasitic growth-phase extracts of Coccidioides immitis, an antigen from the spherule culture supernatant fluid detected a specific antibody in heretofore serologically negative suspect coccidioidomycosis human sera when diffused in agar-gel. This antigen-antibody reaction occurred also in some of the serologically positive human coccidioidomycosis sera. This study indicates that this antigen-antibody reaction should be utilized as a possible routine serological test for complete serodiagnosis.
