Blastomycosis
General information
Blastomycosis is an uncommon, but potentially serious fungal infection. It primarily affects the lungs, and is caused by the fungus Blastomyces. The signs and symptoms of illness that can result from exposure to this soil organism are variable.
Approximately 50% of people who are infected with Blastomyces will not have symptoms. Among the infected persons who develop symptoms, the symptoms vary from mild to severe, and can be fatal. A very serious progressive illness involving multiple organ systems can occur in an untreated patient.
