C. gattii cryptococcosis

A photomicrograph of Cryptococcus

Cryptococcosis is a fungal infection caused by fungi that belong to the genus Cryptococcus. There are over 30 different species of Cryptococcus, but two species – Cryptococcus neoformans and Cryptococcus gattii – cause nearly all cryptococcal infections in humans and animals. Most people who develop cryptococcosis have weakened immune systems, although healthy people can also become infected, particularly with C. gattii.

For more information about cryptococcal infections in animals, visit the Healthy Pets web page.
