Abstract

Background and objectives: Cryptococcosis is subacute or chronic respiratory disease caused by yeast like fungus called Cryptococcus neoformans. The disease may metastasize to CNS and other parts of the body. The objective of the study is to find the prevalence of this disease in a sample of patients in Erbil.

Method: One hundred and twenty eight patients with chronic respiratory tract infection were included in this study. Early morning sputum sample was collected from each patient and subjected to both direct examination and culture

Results: The study showed 24 positive cases of Cryptococcosis, from the total 128 patients examined; 16 of them (66.6%) gave positive culture for Cryptococcus neoformans while 8 (33.3%) gave positive culture for opportunistic species of Cryptococcus. The latter were immunocompromised   individuals.

Conclusion: It is concluded that looking for Cryptococcus, is quite significant in patients with chronic respiratory diseases.
