Toxoplasma gondiii recognized as one of the most successful zoonotic parasites globally, infecting a wide range of hosts including camelids. This infection can lead to serious outcomes such as abortion, neonatal death, or fetal abnormalities. Camels play a crucial role in the economic, ecological, and social landscapes of various regions, particularly in the Middle East, highlighting the importance of close health monitoring and disease screening. Hence in this study, sera from 409 dromedary camels (39 males and 370 females) were examined for T. gondii IgG antibodies using the Modified Agglutination Test (MAT). Both univariable and multivariable statistical analyses were performed using SPSS to identify the risk factors. A seroprevalence of 32% was found with 74% of the reactive specimens exhibiting a MAT titer ≤ 80. Univariate analysis ruled out sex and season as significant risk factors. Multivariable analysis confirmed age and area as statistically significant factors (P value < 0.05) associated with T. gondii seropositivity in camels. Overall, the finding of the present study confirms that T. gondii is prevalent and widely distributed in camels in suburban areas of Qatar. Given the veterinary and economic implications, there is an urgent need for further investigations into the infection's risk factors and its zoonotic impact.
刚地弓形虫被认为是全球最成功的人畜共患寄生虫之一,可感染包括骆驼科动物在内的多种宿主。这种感染可导致严重后果,如流产、新生儿死亡或胎儿畸形。骆驼在各个地区的经济、生态和社会格局中发挥着关键作用,尤其是在中东地区,这凸显了密切健康监测和疾病筛查的重要性。因此,在本研究中,使用改良凝集试验(MAT)对409头单峰骆驼(39头雄性和370头雌性)的血清进行了弓形虫IgG抗体检测。使用SPSS进行单变量和多变量统计分析以确定风险因素。发现血清阳性率为32%,74%的反应性标本MAT滴度≤80。单变量分析排除性别和季节为显著风险因素。多变量分析确认年龄和地区是与骆驼弓形虫血清阳性相关的统计学显著因素(P值<0.05)。总体而言,本研究结果证实,弓形虫在卡塔尔郊区的骆驼中普遍存在且分布广泛。鉴于其兽医和经济影响,迫切需要进一步调查该感染的风险因素及其人畜共患影响。
