Histoplasma capsulatum fungal macroconidium

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

Chronic lung disease resembles tuberculosis and can worsen over months or years. The disseminated form is fatal unless treated.

Is histoplasmosis treatable?

Yes. Antifungal medications are used to treat severe cases of acute histoplasmosis and all cases of chronic and disseminated disease. Mild disease usually resolves without treatment. Past infection results in partial protection against ill effects if reinfected.

Where is H. capsulatum found?

H. capsulatum is found throughout the world and is endemic in certain areas of the United States. The fungus has been found in poultry house litter, caves, areas harboring bats, and in bird roosts.
