Monk Parakeets () are medium-sized parrots that due to international pet trade currently exist as invasive species in 19 countries globally. Such is the case of Chile, where Monk Parakeets have thrived in the city of Santiago. spp. and spp. are worldwide distributed gastrointestinal parasites whose potential hosts include birds and humans. The present study sought to determine the presence of these pathogens in Monk Parakeets from Santiago. During the austral summers of 2017 and 2018, 207 Monk Parakeet nestlings were captured, and fecal samples were studied via microscopical analyses. Environmental data related to the trees in which the nestlings were captured were analyzed to establish the existence of infection clusters. Associations between spatial clusters, environmental variables, and the presence or absence of these pathogens were explored. In total, 33 samples were positive to the presence of one or both protozoa. Of the 33, spp. oocysts were detected in 10 nestlings (30%) while spp. cysts were detected in 25 (76%). Two nestlings presented poly-parasitism (6%). Statistical analyses established pruned trees as a potential protective factor against infection with these parasites. The present study corresponds to the second report of spp. in Monk Parakeets in Chile and the first worldwide report of spp. in these birds, emphasizing Monk Parakeet's potential role as a reservoir and pathogen disseminator, especially in urban environments.
和尚鹦鹉是中型鹦鹉，由于国际宠物贸易，目前在全球19个国家作为入侵物种存在。智利就是这种情况，和尚鹦鹉在圣地亚哥市大量繁殖。 属和 属是分布于世界各地的胃肠道寄生虫，其潜在宿主包括鸟类和人类。本研究旨在确定圣地亚哥和尚鹦鹉体内这些病原体的存在情况。在2017年和2018年南半球夏季，捕获了207只和尚鹦鹉雏鸟，并通过显微镜分析对粪便样本进行了研究。分析了与捕获雏鸟的树木相关的环境数据，以确定感染集群的存在。探讨了空间集群、环境变量与这些病原体存在与否之间的关联。总共33个样本对一种或两种原生动物的存在呈阳性。在这33个样本中，在10只雏鸟（30%）中检测到 属卵囊，在25只雏鸟（76%）中检测到 属包囊。两只雏鸟出现多重寄生（6%）。统计分析确定修剪过的树木是预防这些寄生虫感染的潜在保护因素。本研究是智利和尚鹦鹉中 属的第二篇报告，也是这些鸟类中 属在全球的第一篇报告，强调了和尚鹦鹉作为宿主和病原体传播者的潜在作用，特别是在城市环境中。
