Blasto, Blastomycosis
AffectedAnimals:
Dogs, humans, cats, horses, and occasionally other animals may be affected. Most dogs with the infection are between one and five years of age. Males have a higher risk than females, and may be less responsive to treatment. Immunosuppressed animals are more at risk; animals that become infected may have an underlying immune-system defect, or may be on immunosuppressive medications.
Overview:
Blastomycosis is an infection caused by the fungal organism Blastomyces dermatidis. The disease usually results in respiratory infection; however, the organism can cause disease in many body tissues including the eyes, skin, reproductive tract, and bones. Blastomycosis is a serious disease that can be fatal.
Blastomyces dermatidis is found in the environment predominantly in the Missouri, Ohio, Tennessee, and Mississippi river valleys. Although all animals in these regions are exposed to the organism, only some animals will develop infections. A compromised immune system is the primary risk factor.
Symptoms depend upon the tissues infected by the organism. Treatment requires the use of antifungal medications, often for several weeks to months. In some instances, a cure is not possible and death may result. However, constant medication may keep the disease under control.
