Methods: The total of 50 pigeon excreta were collected and cultured on the brain heart infusion agar and Saboured dextrose agar with Chloramphenicol media, to isolate Cryptococcus neoformans at the 25 degrees centigrade and 37degrees centigrade. Identification was performed by direct examination and by means of the urease test and Carbohydrate assimilation. Finding: From 50 pigeon excreta 2 cases (4%) Cryptococcus neoformans were detected. Besides the Cryptococcus neoformans were isolated 10 species of Cryptococcus Candida unigattulatus 4 cases (5.72%), Candida laurentii 3 cases (4.28%), Candida albidus 2 cases (2.86%) and Candida humicola 1 cases (1.43).
