Neospora caninum is a protozoan responsible for abortions, stillbirths (mainly among cattle) and neuromuscular diseases in dogs. Its importance in wild species and its impact on the environmental preservation of different ecosystems have been little described. This study aimed to investigate the presence of anti-N. caninum antibodies in feral cats on the island of Fernando de Noronha and contribute epidemiological data on this disease in these animals and its impact on the environmental preservation of the island. Serum samples from 257 feral cats on the island were analyzed through the Neospora agglutination test (NAT) to search for anti-Neospora caninum antibodies. Among the 257 serum samples analyzed, 8 (3.11%) were positive in the NAT. The antibody titers were 20 in seven animals (87.5%) and 40 in one animal (12.5%). These results demonstrate that feral cats are exposed to infection by N. caninum on the island of Fernando de Noronha, at a low frequency. Greater knowledge on this infection in this animal species in this insular environment is important for elucidating its impact on the conservation of species and the maintenance of this parasite on the island.
犬新孢子虫是一种原生动物，可导致流产、死产（主要发生在牛群中）以及犬类的神经肌肉疾病。其在野生动物物种中的重要性以及对不同生态系统环境保护的影响鲜有描述。本研究旨在调查费尔南多·迪诺罗尼亚岛上野生猫科动物中抗犬新孢子虫抗体的存在情况，并提供有关这些动物中该疾病的流行病学数据及其对该岛环境保护的影响。通过新孢子虫凝集试验（NAT）对该岛上257只野生猫科动物的血清样本进行分析，以寻找抗犬新孢子虫抗体。在所分析的257份血清样本中，有8份（3.11%）在NAT中呈阳性。7只动物（87.5%）的抗体滴度为20，1只动物（12.5%）的抗体滴度为40。这些结果表明，在费尔南多·迪诺罗尼亚岛上，野生猫科动物感染犬新孢子虫的频率较低。在这个岛屿环境中，深入了解这种动物物种的感染情况对于阐明其对物种保护以及该寄生虫在岛上存续的影响至关重要。
