The objective of this study was to determine the prevalence and diversity of gastrointestinal parasites in fecal samples from wild birds and mammals from the State of Paraná. In total, 220 stool samples were sent to Parasitic Diseases Laboratory of the Federal University of Paraná during 13 months (Jan/2013-Jan/2014). A total of 52.7% (116/220) of the animals were positive for cysts, oocysts, eggs and/or trophozoites. In birds, the positivity rate was 37.9% (25/66) and mammals was 59.1% (91/154). Strongyloidea superfamily eggs were observed in 37.3% (82/220) of the samples, Eimeria spp. in 10% (22/220), and Trichuris spp. in 4.5% (10/220). The most frequent mammal species were llamas (Lama glama), and dromedaries (Camelus bactrianus) with infection rate of 70.1% (54/77) and 60.8% (14/23), respectively. In other hand, cockatiels (Nymphicus hollandicus) and ring necks (Psittacula krameri), were the most researched birds, with infection rate of 20% (40/50) and 100% (6/6), respectively. A high prevalence of gastrointestinal parasites was observed in most of wildlife animals. Further investigations should be conducted focusing on parasite control strategies and the conservation measurements for harmonizing the human-animal interaction on the long-term, reducing associated health risks.
本研究的目的是确定巴拉那州野生鸟类和哺乳动物粪便样本中胃肠道寄生虫的流行情况和多样性。在13个月（2013年1月至2014年1月）期间，总共220份粪便样本被送往巴拉那联邦大学寄生虫病实验室。共有52.7%（116/220）的动物囊肿、卵囊、虫卵和/或滋养体呈阳性。在鸟类中，阳性率为37.9%（25/66），在哺乳动物中为59.1%（91/154）。在37.3%（82/220）的样本中观察到圆线虫超科虫卵，10%（22/220）的样本中观察到艾美耳属虫卵，4.5%（10/220）的样本中观察到鞭虫属虫卵。最常见的哺乳动物物种是美洲驼（小羊驼）和单峰骆驼，感染率分别为70.1%（54/77）和60.8%（14/23）。另一方面，玄凤鹦鹉和环颈鹦鹉是研究最多的鸟类，感染率分别为20%（40/50）和100%（6/6）。在大多数野生动物中观察到胃肠道寄生虫的高流行率。应进一步开展调查，重点关注寄生虫控制策略以及长期协调人与动物互动的保护措施，以降低相关健康风险。
