Sera from 961 horses from Brazil were tested for antibodies against the major surface antigens SnSAG4 and NhSAG1 to determine the seroprevalence of Sarcocystis neurona and Neospora hughesi, respectively. Antibodies against SnSAG4 were detected in 669 (69.6%) of the horses, while antibodies against NhSAG1 were detected in only 24 (2.5%) of the horses. These serologic results suggest that there is a high concentration of S. neurona in the environment of Brazil, which results in marked exposure of horses to this parasite. Additionally, the data further confirm that infection with Neospora spp. is relatively uncommon in horses.
对来自巴西的961匹马的血清进行检测，以检测针对主要表面抗原SnSAG4和NhSAG1的抗体，从而分别确定马神经肉孢子虫和休氏新孢子虫的血清阳性率。在669匹（69.6%）马中检测到了针对SnSAG4的抗体，而仅在24匹（2.5%）马中检测到了针对NhSAG1的抗体。这些血清学结果表明，巴西环境中存在高浓度的马神经肉孢子虫，这导致马匹大量接触这种寄生虫。此外，数据进一步证实新孢子虫属感染在马匹中相对不常见。
