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).
