Histoplasmosis Survey of Dogs in Louisville, Kentucky

Abstract
A search for H. capsulatum was made on 303 dogs. All dogs suspected of being infected with the rabies virus and those weighing 100 or more lbs. were excluded. The direct microscopic examination of stained bone marrow smears and splenic impressions failed to reveal the fungus in the 303 dogs. Cultures of bone marrow and portions of spleen from these dogs failed to yield organisms resembling H. capsulatum when incubated on a modified Sabouraud''s medium at room temp. for 1 month.
