|Description:||This photograph depicts a test tube slant culture, which had been colonized by what was determined to be two different organisms, Cryptococcus neoformans and Histoplasma capsulatum. These fungal organisms were isolated from soil specimens retrieved from Hopkinsville, Kentucky.|
Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum. Its symptoms vary greatly, but the disease primarily affects the lungs. Occasionally, other organs are affected. This form of the disease is called disseminated histoplasmosis, and it can be fatal if untreated.
Life-threatening infections caused by the encapsulated fungal pathogen Cryptococcus neoformans have been increasing steadily over the past 10 years because of the onset of AIDS, and the expanded use of immunosuppressive drugs.
