It is an opportunistic fungal pathogen notoriously known as the most common cause of fungal meningitis (infection and inflammation of the meninges) in immunocompromised patients (such as people with AIDS). Cryptococcosis is a systemic fungal disease that may affect the respiratory tract (especially the nasal cavity), CNS, eyes, and skin (particularly of the face and neck of cats). The causal fungi, Cryptococcus neoformans and C gattii, exist in the environment and in tissues in a yeast form. Although C. neoformans and C. gattii are regarded as the principle pathogenic species, Cryptococcus albidus and C. laurentii have on occasion also been implicated in human infection.
