The Endemic Mimic: Blastomycosis An Illness Often Misdiagnosed

Blastomycosis is another infectious disease that often is initially misdiagnosed. It usually is a disease of “normal” persons, unlike many other fungal pathogens which cause opportunistic infections in immunocompromised patients. This infection occurs both in epidemics and sporadically as one of the endemic mycoses...

The reported incidence of blastomycosis depends on recognition of the clinical diagnosis because there are no good or reliable markers of previous infection such as the skin test for tuberculosis, histoplasmosis, or coccidioidomycosis...

 The Endemic Mimic: Blastomycosis An Illness Often Misdiagnosed

One of the endemic fungi, Blastomyces dermatitidis, can cause epidemics of infection with multiple persons involved in a point source outbreak but more commonly causes sporadic cases of infection within the areas of endemicity. Blastomycosis can present as an acute pneumonia which is often misdiagnosed as acute pneumococcal pneumonia or the infection may present as a chronic pneumonia along with weight loss, night sweats, hemoptysis, and a lung mass suggesting tuberculosis or carcinoma of the lung.

I have put together this site in memory of my Golden Retriever, who is believed to have died from Blastomycosis. I am collecting all the information I can find about this fungal disease.

Fun With Microbiology (What's Buggin' You?)

Infection most likely occurs through inhalation of fungal spores when the environmental fungus is disturbed (raking leaves, moving woodpiles, gardening/planting, etc.). Once inside the lungs, the change of environment (carbon dioxide content, organic nutrients, pH and primarily the increased temperature (37oC)), and causes the fungal spores to develop into the yeast cell form.

CDC

Blastomycosis is an infection caused by a fungus called Blastomyces. The fungus lives in the environment, particularly in moist soil and in decomposing matter such as wood and leaves.

Conditions for multiplication of this pathogen are particularly good when soil is rich in excretions from animals and the soil is acidy and moist containing decaying organic material.

Thoracic.org

Blastomycosis is a disease caused by breathing in a fungus named Blastomyces dermatidis. This fungus is found in moist soil of rotting plants or wood.

Tom Volk's Fungus of the Month

Blastomycosis starts out as a lung infection caused by inhalation of the conidia. The conidia transform into the yeast form, The transformation into a yeast involves many physiological and biochemical changes, having the effect of "buying some time" for the fungus to become established.
