Summary
The clinical history of a fatal case of acute disseminated Histoplasmosis in a 3-month-old infant is described. A liver biopsy performed ante mortem revealed numerous encapsulated organisms which were identified at H.capsulatum. This suggests the applicability of this technique as a diagnostic tool. An autopsy showed extensive involvement, the organisms being found in the lungs, thymus, mediastinal and retroperitoneal nodes, liver, adrenals, spleen, and kidneys.
A portion of emulsified liver was inoculated into Swiss mice andH. capsulatum was recovered from the mouse tissues 4 weeks after inoculation.
A study was made of the cultural characteristic of this culture and it conformed to those previously described for other strains. A study of its fermentation properties disclosed no acid or gas production in media containing glucose, sucrose, lactose, maltose, mannose, rhamnose, trehalose, dulcitol, sorbitol, mannitol, and xylose.
