False-colour light micrograph of a parasitic,yeastlike fungus called Histoplasma capsulatum,the spores of which,when inhaled,cause a respiratory disease called histoplasmosis. The primary pulmonary form is usually harmless. Occasionally a progressive histoplasmosis develops which resembles tuberculosis. Histoplasmin,an antigenic material,is produced from the fungus to test against the disease. H.capsulatum has a mycelial form (seen here) which is found in soil enriched by animal excrement. The spores are produced by the hyphae,the threadlike structures | |
