Preparation of monoclonal antibodies that differentiate between Histoplasma capsulatum variant capsulatum and H. capsulatum variant duboisii.
The immunosuppressive drug cyclophosphamide was used to facilitate the production of monoclonal antibodies (Mabs) which differentiated between the yeast phase of the two variants of the dimorphic fungus Histoplasma capsulatum by both enzyme-linked immunosorbent assay and Western blot. Two Mabs are described, identifying epitopes on a 70-75 kDa molecule, which are specific to H. capsulatum var. capsulatum and which do not identify epitopes of H. capsulatum var. duboisii. These Mabs have potential use in the epidemiology and serodiagnosis of histoplasmosis in areas where both classical and African forms of the disease occur.
