Cryptococcosis is a common opportunistic fungal infection caused by encapsulated yeast of the Cryptococcus genus, mainly by the Cryptococcus neoformans and Cryptococcus gattii species. The fungus is acquired through the inhalation of environmental propagules or, more rarely, through organ transplants in immune-compromised individuals. Domestic pigeons (Columba livia) are related to the infection, mainly as natural... Read more.
