From Internet:
Blastomycosis is a chronic infection characterized by a granulomatous and suppurative lesion. It is
caused by a single fungal species, blastomyces dermatitidis, which is a thick walled spherical yeast that
usually produces single buds. The bud and parent yeast have a characteristically wide base of
attachment. The infection is initiated by inhalation of the dimorphic fungus. Dissemination may occur to
any organ from the lung, but preferentially to the skin and bones.

Blastomycosis is endemic to eastern parts of the United States but is also seen throughout Canada and
Central America. The natural habitat of B. dermatitidis is unresolved. Isolates have been found in the
soil from barns, a chicken house, a cattle crossing, and abandoned shacks. Although animal- to- man
transmission has not been identified, canine blastomycosis is common. The endemic area extends
roughly east from states that border the Mississippi river. In particular blastomycosis is endemic in the
southeast, Ohio valley and Illinois. Blastomycosis is at least 6 times more common in men and typically
effects middle- aged patients.
