PRESENCIA DE Cryptococcus neoformans EN EXCRETAS DE PALOMAS URBANAS EN SAN MIGUEL DE TUCUMÁN - ARGENTINA

Abstract

With the purpose of detecting the presence of Cryptococcus neoformans complex in excreta of pigeons inhabitating public spaces belonging to the urban perimeter of San Miguel de Tucumán, Argentina, one hundred samples were collected from five different locations. Niger seed agar plates were used as means of isolation and yeasts were identified through the presence of capsule, urease test, fenoloxidase production, carbohydrate assimilation and growth at 37ºC. Species was determined with the CGB method. C. neoformans var. neoformans was isolated in all 55 samples of the studied areas showing a wide distribution downtown, mainly in dried excreta settlings. In vitro sensibility in front of Fluconazol, Itraconazol, Anfotericina B and Voriconazol was fixed by means of the diffusion method by using Neo-Sensitabs tablet. All isolations proved to be sensible to the tested antifungal.
