Specific immunodiffusion test for blastomycosis.
نویسندگان
چکیده
A specific immunodiffusion test for blastomycosis has been developed. The test permitted the detection of approximately 80% of 113 proven cases of blastomycosis. Two diagnostically important precipitins designated A and B were frequently recognized in patients with blastomycosis. Routine use of reference sera containing the A and B precipitins in immunodiffusion tests would permit the specific diagnosis of blastomycosis without the need for parallel tests with coccidioidin and histoplasmin.

Antigen and antibody testing for the diagnosis of blastomycosis in dogs.
BACKGROUND Early diagnosis and treatment are associated with an improved prognosis in blastomycosis. The diagnosis of blastomycosis may be missed by cytology, histopathology, culture, or serology. An enzyme immunoassay (EIA) for detection of Blastomyces dermatitidis galactomannan antigen in body fluids has been used for rapid diagnosis of blastomycosis in humans. HYPOTHESIS Measurement of Bla...
متن کاملPreparation of reference antisera for laboratory diagnosis of blastomycosis.
Antiserum was prepared in rabbits against the A antigen and a new antigen (labeled the D antigen) of yeast-phase cells of Blastomyces dermatitidis by using immunoelectrophoretic precipitin arcs as vaccine. The antiserum can be used as a reference serum in the immunodiffusion test for identyfying antibodies to the A antigen in sera from patients thought to have blastomycosis. Antibodies to the D...

Blastomycosis was diagnosed in six nondomestic felids from eastern Tennessee, including two Asian lions (Panthera leo persicus), one African lion (Panthera leo), one Siberian tiger (Panthera tigris), one cheetah (Acinonyx jubatus), and one snow leopard (Panthera uncia). Clinical signs included lethargy, anorexia, weight loss, dyspnea, sneezing. ataxia, and paresis. Variable nonspecific changes ...
متن کاملHuman and Canine Pulmonary Blastomycosis, North Carolina, 2001–2002
We investigated a cluster of blastomycosis in 8 humans and 4 dogs in a rural North Carolina community. Delayed diagnosis, difficulty isolating Blastomyces dermatitidis in nature, and lack of a sensitive and specific test to assess exposure make outbreaks of this disease difficult to study.
متن کاملPulmonary blastomycosis: an appraisal of diagnostic techniques.
OBJECTIVES Pulmonary blastomycosis often mimics bacterial pneumonia or bronchogenic carcinoma, which may result in delayed therapy or the performance of unnecessary diagnostic procedures. We have reviewed the utilization of diagnostic techniques in the workup of patients with pulmonary blastomycosis, defined their diagnostic yields, and proposed an optimal diagnostic approach for the patient in...
