Toxoplasma gondii, Neospora caninum and Sarcocystis neurona are related apicomplexan parasites that cause reproductive and neurological disorders in a wide range of domestic and wild animals. In the present study, the immunofluorescence antibody test (IFAT) was used to investigate the presence of antibodies against T. gondii, N. caninum and S. neurona in the sera of 11 free-living jaguars (Panthera onca) in two protected areas in the Pantanal region of Mato Grosso state, Brazil. Ten jaguars (90.9%) showed seropositivity for T. gondii, eight (72.7%) for S. neurona, and seven (63.6%) for N. caninum antigens. Our findings reveal exposure of jaguars to these related coccidian parasites and circulation of these pathogens in this wild ecosystem. To the best of our knowledge, this is the first serological detection of N. caninum and S. neurona in free-living jaguars.
刚地弓形虫、犬新孢子虫和神经肉孢子虫是相关的顶复门寄生虫，可在多种家养和野生动物中引发生殖和神经紊乱。在本研究中，采用免疫荧光抗体试验（IFAT）调查了巴西马托格罗索州潘塔纳尔地区两个保护区内11只野生美洲豹（Panthera onca）血清中抗刚地弓形虫、犬新孢子虫和神经肉孢子虫抗体的存在情况。10只美洲豹（90.9%）对刚地弓形虫呈血清阳性，8只（72.7%）对神经肉孢子虫呈血清阳性，7只（63.6%）对犬新孢子虫抗原呈血清阳性。我们的研究结果揭示了美洲豹接触这些相关球虫寄生虫的情况以及这些病原体在这个野生生态系统中的循环。据我们所知，这是首次在野生美洲豹中对犬新孢子虫和神经肉孢子虫进行血清学检测。
