About Blastomycosis Blastomycosis is a rare fungal infection usually acquired by breathing in the spores of the fungi Blastomyces dermatitidis or Blastomyces gilchristii. On this page: Transmission Symptoms Duration of Illness Diagnosis Treatment Prevention Fact Sheet Transmission Blastomycosis is usually caused by inhaling airborne spores from contaminated soil into the lungs. Spores are more likely to be airborne after contaminated soil is disturbed by activities such as excavation, construction, digging, or wood clearing.
Very rarely, the fungus can infect an open skin wound and cause infection in just that area of the body. Blastomycosis is not spread person-to-person or animal-to-person.
Duration of Illness The duration of illness caused by blastomycosis varies greatly between patients. Diagnosis Blastomycosis may be diagnosed by: Culture Blastomyces species can be isolated from saliva, respiratory samples, lung biopsies, skin, or other infected tissues Cytology smear direct microscopic identification of broad-based budding yeast Histopathology of surgical biopsies Urine antigen test or serum antigen test Serum antibody test less reliable Your doctor may also ask about your travel history, outdoor activities, or the environment around your home to help determine if you might have been exposed to Blastomyces spores.
This type of fungus tends to live in the soil and decaying organic matter e. Blastomycosis occurs most often in the mid-Atlantic states of North America, especially the Ohio, Mississippi, and Missouri river valley regions. Dogs become infected after breathing in Blastomyces fungal spores in the environment. Those infected can become extremely ill, commonly with respiratory disease, and many will die without treatment.
Blastomycosis fungal infection in dogs is common. Humans can also become infected in the same manner as dogs. Disease is not spread from animal to animal and is not contagious. Blastomycosis infections in other animals e. Respiratory disease is typical. Symptoms include coughing, trouble breathing, and congestion. Blastomycosis can affect many other areas of the body including the eyes e.
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. Blastomycosis fact, P PDF. Questions about Blastomycosis? Contact us!
