Histoplasma capsulatum Darling 1906

Magnified 300X, this photomicrograph revealed the presence of Histoplasma capsulatum var. duboisii fungal organisms in an unidentified tissue sample.What is histoplasmosis?Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum. Its symptoms vary greatly, but the disease primarily affect the lungs. Occasionally, other organs are affected. This form of the disease is called disseminated histoplasmosis, and it can be fatal if untreated.Created: 1972

This photograph revealed slant-culture test tubes, each containing a colony of Histoplasma capsulatum fungal organisms, which had been isolated from Israeli soil samples. H. capsulatum is the etiologic agent responsible for causing the disease known as histoplasmosis.What is histoplasmosis?Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum.

At a magnification of 400X, this photomicrograph revealed some of the ultrastructural morphology exhibited by Histoplasma capsulatum fungal macroconidia and macroconidia, which were isolated from Israeli soil samples.Created: 1974

At a magnification of 1125X, this photomicrograph revealed some of the ultrastructural morphology exhibited by a Histoplasma capsulatum fungal macroconidium. The reproductive spores produced by H. capsulatum can be either macroconidia or microconidia. It is the macroconidia that exhibits finger-like projections from its surface, whereas, the microconidia are much smaller, round, and possess a smooth surface. See PHIL 299 for a depiction of both macro- and microconidia.What is histoplasmosis?Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum.

Under a magnification of 1125X this photomicrograph depicted the the presence of three Histoplasma capsulatum macroconidia, differentiated from the microconidia by the presence of projections emanating from their surface, as seen in this case.
