本研究旨在确定沙特阿拉伯利雅得省用于运动目的的马的弓形虫血清阳性率。总共分析了来自临床健康马的266份血清样本的抗T抗体。用Sabin-Feldman染料试验检测弓形虫抗体。抗T. 84匹马（31.6%）检出弓形虫，特异性滴度分别为1：16（78匹，患病率29.3%）、1：64（4匹，患病率1.5%）和1：256（2匹，患病率0.8%）。Shaqra的血清反应阳性马的数量（43.7%）远远高于其他地区，Al-Majmaah的血清反应阳性马的数量最少（11.0%）。但6个地点的血清阳性率差异无统计学意义（P > 0.05）。相比之下，利雅得省的总体血清阳性率高于其他国家的报告。在该地区，马不是人类弓形虫病的直接感染源。通常人类感染是通过猫，这是该寄生虫的水库主机。
The aim of the present study was to determine the seroprevalence of Toxoplasma gondii in horses used for sporting purposes in the Province of Riyadh, Saudi Arabia. In total, 266 serum samples from clinically healthy horses were analyzed for anti-T. gondii antibodies using the Sabin-Feldman dye test. Antibodies to T. gondii were found in 84 (31.6%) horses, with specific titers of 1:16 (78 with a prevalence of 29.3%), 1:64 (4 with a prevalence of 1.5%), and 1:256 (2 with a prevalence of 0.8%). The number of seropositive horses in Shaqra (43.7%) was considerably higher than in other regions, with the lowest occurring in Al-Majmaah (11.0%). However, the differences in seroprevalence between the 6 locations were not statistically significant (P > 0.05). In contrast, the overall seroprevalence in Riyadh province was higher than that reported in other countries. Horses are not a direct source of infection for human toxoplasmosis in this region. Usually human infection is facilitated via cats, which are the reservoir hosts for this parasite.
