Cryptococcosis is a systemic fungal infectious disease caused by the Cryptococcus neoformans/Cryptococcus gattii complex (serotypes A and D). Cryptococcus infections occur by inhalation of blastospores and basidiospores that establish an acute or chronic primary lung infection caused by capsule yeast, especially C. neoformans. The urban pigeon (Columba livia) is the most important as a reservoir for the fungus C. neoformans; this is the cause of fungal meningitis, which causes approximately 278,000 cases and 181,000 deaths each year. In the present study, 100 samples of pigeon excreta were taken, carrying out a cross-sectional, observational and descriptive study. The results showed an identification percentage of 30% positive for C. neoformans and 70% corresponding to the presence of other fungal species. Concluding that dovecotes and pigeon feces continue to be one of the main mechanisms of fungal transmission and multiple diseases.
