Blastomycosis

 

a chronic disease of the skin and internal organs in animals, caused by a yeastlike microscopic fungus Blastomyces dermatitidis. The natural reservoir of the fungus is soil. The animals mainly affected are dogs. Most susceptible to experimental infection are horses, sheep, guinea pigs, and hamsters. Diseased animals that discharge the fungus with mucus, in urine, and with the exudates in skin infection are the source of infection. Infection apparently occurs through injured skin or respiratory passages. Treatment has not been developed. Diseased animals are killed in order to prevent infection of humans.

Currently, there is no skin test or a reliable serology test for blastomycosis.
During 1986-1995, a total of 670 cases of blastomycosis were reported to DOH, representing a statewide mean annual incidence rate of 1.
There are few reports of pulmonary blastomycosis infection progressing to adult respiratory distress syndrome (ARDS).
First, the clinical course of blastomycosis has been found to be correlated with the amount of inoculum (conidia) initially acquired (typically through inhalation) (7).
Cure rates of greater than 90% have been reported for blastomycosis in patients treated with 200-400 mg/day of itraconazole, which has less toxicity than does ketoconazole.
Some patients may recover from North American blastomycosis without treatment, he said, but reactivation of the disease may occur after long periods (up to 40 years later) in treated and untreated patients.
Coccidioidomycosis, histoplasmosis and blastomycosis (also defines as "endemic mycoses" due to their prevalence in North America) are fungal diseases that, for the most part, begin as mild respiratory infections but often progress in a certain percentage of patients to a serious, disseminated form of disease.
Blastomycosis is considered endemic to the south-central, southeastern, and midwestern US states, particularly those bordering the Ohio and Mississippi Rivers and in parts of the United States and Canada surrounding the Great Lakes and the Saint Lawrence River (2,5).
Blastomycosis is a chronic fun gal disease that primarily affects the lower respiratory tract.
Very encouraging" data have been posted regarding voriconazole for a variety of other fungal infections, including disseminated candidiasis and candidemia refractory to standard first-generation triazole therapy, esophageal candidiasis, fusariosis, and blastomycosis.
The other diagnoses included cytomegalovirus, tularemia, ehrlichiosis, blastomycosis, and enterovirus infection.
