Cryptococcosis has been a significant cause of morbidity and mortality in patients with Aids. Many reservoirs of the agent Cryptococcus neoformans have been reported, but the ecology of this yeast must be elucidated in order to establish surveillance programs and to prevent infections. The objective of this study was to evaluate the presence of C. neoformans in Rio de Janeiro City, RJ, Brazil. Ten churches were selected for sampling and detection of the yeast collecting pigeon dropping, air samples from church towers and neighboring areas during one year. The data demonstrated that C. neoformans has been present in every church selected and was present in 37.8% of 219 pigeon dropping samples. As well as, the yeast was isolated from soil, insects, eggs, pigeon nests and feathers. Fifteen air samples (4.9%) were positive. The growth on C.G.B. medium showed that all strains belonged to C. neoformans var. neoformans, with 98.8% of the strains belonging to serotype A.
隐球菌病一直是艾滋病患者发病和死亡的重要原因。已报道新型隐球菌病原体有许多储存宿主，但为了建立监测项目并预防感染，必须阐明这种酵母菌的生态学。本研究的目的是评估巴西里约热内卢市新型隐球菌的存在情况。在一年时间里，选择了十座教堂进行采样，并从教堂塔楼及周边地区收集鸽粪、空气样本以检测酵母菌。数据表明，在所选择的每座教堂中都存在新型隐球菌，在219份鸽粪样本中有37.8%检测到该菌。此外，还从土壤、昆虫、鸟蛋、鸽巢和羽毛中分离出了这种酵母菌。15份空气样本（4.9%）呈阳性。在C.G.B.培养基上的生长情况表明，所有菌株均属于新型隐球菌变种新型隐球菌，其中98.8%的菌株属于血清型A。
