What is Cryptococcus?
Cryptococcus is a type of fungus that is found in the soil worldwide, usually in association with bird droppings. The major species of Cryptococcus that causes illness in human is Cryptococcus neoformans. Another less common species that can also cause disease in humans, Cryptococcus gattii, has been isolated from eucalyptus trees in tropical and sub-tropical regions. Since 1999, C. gattii has also been found in regions of the Pacific Northwest, particularly Victoria Island in British Columbia, and Oregon and Washington in the United States.
