Yeasts in pigeon feacal droppings in Lisbon - Portugal, 1994

Abstract

In this work, the results of a preliminary survey held in city of Lisbon. Eighty faecal samples were examined between Summer and Autumn, 1994, from twelve different urban areas, mainly near churchs and monuments where birds nest, rest or eat. From each sample 1 g was weighted and suspensed in 10 ml of destilled sterilized water and consecutive decimal diluitions were executed. Yeasts were enumerated and grouped by species, based on morphological types. On eighty faecal samples the most prevalent yeasts identified were: Candida humicola (51.5%), Candida albicans (48.7%), Cryptococcus neoformans (5%) and Trichosporon cutaneum (37.5%).
