Your vet will do a physical examination and ask about your dog’s history. If your dog has sores or cysts, a cough, and breathing problems, your vet might consider the fungus. To confirm, they will do some blastomycosis testing.
Causes and Symptoms
Blastomyces dermatitidis is found in soils in the Great Lakes region, Ohio and Mississippi River Valleys, and the south-eastern United States. Blastomyces dermatitidis thrives in damp soil and decomposing debris like wood and leaves. Mold spores spread the fungus.
Epidemiology
In 5% to 10% of instances, the central nervous system is implicated, including cases of meningitis and intracranial or epidural abscesses. Blastomycosis is found throughout the Ohio and Mississippi River valleys, the Great Lakes region, and the south-eastern United States.
Diagnosis and Treatment
For a conclusive diagnosis, direct imaging of Blastomyces dermatitides is required. The yield of sputum specimens stained with 10% potassium hydroxide or a fungal stain is approximately 80%. Pseudoepitheliomatous hyperplasia with neutrophilic abscesses is shown by biopsy and histological investigation of skin lesions.
