Blastomyces dermatitidis: Stability studies on different yeast lysate antigens
In Trial 1, 19 lots of Blastomyces dermatitidis (T-58; Tennessee dog isolate) were assayed to determine the stability of the reagents following storage. The reactivity of the antigens, produced from 1989 to 2012 and stored at 4 ̊C, was determined by comparing antibody detection (enzyme-linked immunosorbent assay; ELISA) in 12 serum specimens from immunized rabbits. All of the 19 reagents produce...
متن کاملYeast- and mycelial-phase antigens of Blastomyces dermatitidis: comparison using disc gel electrophoresis.
The disc gel electrophoretic patterns obtained with skin test-active (mycelial and yeast) antigens of Blastomyces dermatitidis were compared. As would be expected, the blastomycins (mycelial-phase) and the cytoplasmic ultrafiltrates (yeast-phase) were heterogeneous mixtures containing proteins, glycoproteins, lipoproteins, and carbohydrates. The skin test-active cytoplasmic ultrafiltrates and t...
متن کاملCutaneous lesions showing giant yeast forms of Blastomyces dermatitidis.
BACKGROUND The yeast forms of Blastomyces dermatitidis usually range from 8 to 15-20 micro m in diameter. Larger yeast forms have previously been reported only twice in immunosuppressed patients. In both patients these large forms were seen within the lung. CASE REPORT We present a 14-year-old cardiac transplant patient, who presented 36 days following his transplantation with acute respirato...
متن کاملMolecular epidemiology of Blastomyces dermatitidis.
The inhalation of conidia of Blastomyces dermatitidis, a fungus found in soil, causes disease in humans and animals. We studied the genetic diversity of this pathogen by extracting DNA yeasts and analyzing them with a polymerase chain reaction (PCR)-based typing system we developed, which used restriction fragment analysis of amplicons from the regions between the rDNA repeats and allowed us to...
متن کاملDetection of two Blastomyces dermatitidis serotypes by exoantigen analysis.
We evaluated the diagnostic value of antibody to Blastomyces dermatitidis A precipitin arcs for identifying B. dermatitidis cultures by the exoantigen technique with 88 isolates from the United States and Canada, 12 from Africa, and 1 each from India and Israel. In addition, we studied 190 mycelial-form isolates of other fungi which could be confused antigenically or morphologically with B. der...
