The enzyme-linked immunoelectrotransfer blot (EITB) method was evaluated as a suitable method for detecting antibodies against M antigen of Histoplasma capsulatum by use of both glycosylated and deglycosylated M protein of histoplasmin (HMIN). Sera from patients with histoplasmosis,
Chromium chloride was used as a coupling agent for the conjugation of purified cryptococcal polysaccharide to sheep erythrocytes. Sensitized erythrocytes were used in a passive hemagglutination (PHA) assay for antibody to cryptococcal polysaccharide and a passive hemagglutination inhibition (PHI)
Chemotactic activity for human polymorphonuclear neutrophils (PMNs) was detectable in culture filtrates (CFs) of Blastomyces dermatitidis and may have influenced the pathogenesis of blastomycosis. Production of this chemotaxin depended upon culture age and medium; peak levels were achieved after
The lack of well-defined antigens from Blastomyces dermatitidis has hampered the ability to reliably diagnose human infection and study the immunobiology of blastomycosis. We recently discovered a novel surface protein on B. dermatitidis yeasts, designated WI-1, and demonstrated it to be a key
After isoelectric focusing (IEF), fractions of a Blastomyces dermatitidis yeast lysate antigen were analysed for the presence of glycoproteins that may lead to cross-reactivity in immunoassays for the diagnosis of blastomycosis. Five major glycoproteins were apparent, two of which showed
To obtain purified H and M antigens suitable as primary standards in the serological diagnosis of histoplasmosis by agar gel double-diffusion tests, H and M reactive components of histoplasmin were fractionated by column chromatography by using Sephadex G-100, Sephadex G-200, and diethylaminoethyl
