Frequently called the “Chicago Disease,” blastomycosis is a potentially fatal fungal infection that has shown an increasing number of cases in the Chicago area in recent years. There is about a fifty percent survival rate for dogs diagnosed with this infection, making this recent increase in reports a cause for local concern and increased awareness.
Blastomycosis disease is caused by the fungus Blastomyces dermatitidis, which is primarily local to the Midwest and most prominent around areas close to bodies of water. The fungus grows in moist soil heavy with decomposing organic materials such as leaves, wood, or other decaying plant matter. The disease typically occurs when spores from the fungus are inhaled, but they may also enter the body through open sores or wounds.
The disease can affect humans, dogs, cats, horses (several other species have also been reported,) if they come into contact with the fungus. Early detection and diagnosis are key in increasing chances of survival.
Symptoms:
- Fever
- Weight loss
- Puss filled skin lesions
- Eye drainage or weeping
- Film over eyes or inflammation
- Lethargy
- Limping
- Labored breathing, wheezing or pneumonia
- Nausea or flu-like symptoms
Treatment:
- Anti-fungal medication (typically oral)
- Oxygen treatment (in cases of severe respiratory damage)
- Possible hospitalization
- High quality diet to aide in recovery
According to the College of Veterinary Medicine at the University of Illinois, “Illinois is located in the “Blasto Belt” for humans and animals alike. Retrievers, beagles, and other hunting dogs are particularly susceptible to getting blastomycosis because of their outdoor activities.” Blastomycosis in humans is not transmitted through the air from an affected pet, but could be contracted from changing an infected animal’s bandage through skin contact of open wounds.
If you or your pet are experiencing any of the symptoms don’t hesitate to seek medical attention.
