Cryptococcosis: Infection with fungus (usually in a yeast form) from the genus Cryptococcus, such as Cryptococcus neoformans or Cryptococcus gattii. Cryptococcosis is generally a rare condition, but about 7%-15% of people with AIDS may acquire the infection. Infection is rare but can also occur in people with a normally functioning immune system. The infection can manifest as pneumonia with spread to the brain and other organs. Cryptococcal meningoencephalitis is fatal if not treated. Amphotericin B and other antifungal medications are used to treat cryptococcosis.
