Serological screening of 199 serum samples from Dromedary camels-from different cities in Saudi Arabia-was performed using enzyme-linked immunosorbent assay for detecting antibodies against two cyst-forming coccidian parasites, namely Toxoplasma gondii and Neospora caninum. Antibodies against T. gondii were detected in 68 (34.2%) samples, while those against N. caninum were present in 33 (16.6%) samples. The highest seroprevalence of T. gondii antibodies was reported in samples from Taif (51.2%), while the lowest seroprevalence was reported in samples from Riyadh and Hofuf (15.1%). The highest seroprevalence of N. caninum antibodies was reported in samples from Jizan (35.9%) while the lowest was reported in samples from Taif (2.4%). A total of 47 male and 21 female camels exhibited antibodies against T. gondii , while 19 male and 14 female camels showed antibodies against N. caninum . Concurrent detection of both T. gondii and N. caninum antibodies was observed in 18 camels. It has been demonstrated that T. gondii and N. caninum antibodies are prevalent in camels from different cities of the Kingdom of Saudi Arabia.
对来自沙特阿拉伯不同城市的199份单峰骆驼血清样本进行了血清学筛查，采用酶联免疫吸附测定法检测针对两种形成包囊的球虫寄生虫的抗体，即刚地弓形虫和犬新孢子虫。在68份（34.2%）样本中检测到针对刚地弓形虫的抗体，而在33份（16.6%）样本中检测到针对犬新孢子虫的抗体。在来自塔伊夫的样本中，刚地弓形虫抗体的血清阳性率最高（51.2%），而在来自利雅得和胡富夫的样本中血清阳性率最低（15.1%）。在来自吉赞的样本中，犬新孢子虫抗体的血清阳性率最高（35.9%），而在来自塔伊夫的样本中最低（2.4%）。共有47头雄性骆驼和21头雌性骆驼表现出针对刚地弓形虫的抗体，而19头雄性骆驼和14头雌性骆驼表现出针对犬新孢子虫的抗体。在18头骆驼中观察到同时检测到刚地弓形虫和犬新孢子虫抗体。已经证明，刚地弓形虫和犬新孢子虫抗体在沙特阿拉伯王国不同城市的骆驼中普遍存在。
