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.

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.
