Fungi from the genre Cryptococcus are the causative agents of Criptococose in humans and animals, especially Cryptococcus neoformans and Cryptococcus gattii. These are fungi found in a variety of environmental sources including pigeon excrement. This study’s goal is to ascertain whether this fungus is present in the excrement of pigeons from the city of Ji-Paraná or not. The choice of sample collection points focused on areas with a high population of pigeons. 50 samples were collected in 10 different spots. The methodology described by Contin13 was applied in this study. Inoculation by Sabouraud agar, capsule confirmation through microscopy, and a urease test were carried out in the process. The results have shown that 26% out of the 50 samples tested positive for the presence of Cryptococcus neoformans. This confirms the presence of this fungus in the excrement of the pigeons of Ji-Paraná-RO. This study is the first of its kind in this city. It highlights the need for more similar studies in the future. Nevertheless, it is obviously important to avoid contact with pigeons and their excreta for the time being.
