Chapter 3--pulmonary cryptococcosis

Abstract

Cryptococcosis is a systemic mycosis caused by two species of the encapsulated basidiomycetes, Cryptococcus neoformans and C. gattii, which, respectively, cause infection in immunocompromised individuals and in immunologically normal hosts. Patients with T-cell deficiencies are more susceptible to this infection. The spectrum of the disease ranges from asymptomatic pulmonary lesions to disseminated infection with meningoencephalitis. The medical relevance of cryptococcosis increased dramatically as a consequence of the AIDS epidemic and organ transplants.
