Toxoplasmosis, caused by , is a zoonotic infection with significant implications for animal and human health. Congenital transmission leads to reproductive issues affecting livestock productivity. This study aims to assess the prevalence of antibodies in goats and sheep using the Modified Agglutination Test (MAT).
Blood samples were collected from 799 small ruminants (537 sheep and 262 goats) across seven municipalities in Qatar between November 2019 and November 2021. The samples were analyzed using MAT to detect IgG antibodies. Seroprevalence was determined, and statistical analysis was performed to assess risk factors such as age, gender, location, and season.
Of the 799 samples, statistically, 23.0 % tested positive for antibodies, with 18.4 % of sheep and 32.4 % of goats recorded seropositive. Age was identified as a significant risk factor for sheep, with older sheep showing higher seroprevalence, while no significant risk factors were found for goats. Other variables, such as sex, location, and season, showed no significant association.
This study, the first targeting small ruminants in the country, reveals notable differences in prevalence between sheep and goats in Qatar. Age is a key risk factor in sheep, but further research is needed to explore other factors, especially in goats.
由[病原体名称未给出]引起的弓形虫病是一种人畜共患感染病，对动物和人类健康有重大影响。先天性传播会导致影响家畜生产力的繁殖问题。本研究旨在使用改良凝集试验（MAT）评估山羊和绵羊中[病原体名称未给出]抗体的流行情况。
在2019年11月至2021年11月期间，从卡塔尔七个城市的799只小反刍动物（537只绵羊和262只山羊）采集血样。使用MAT分析样本以检测[病原体名称未给出]IgG抗体。确定血清阳性率，并进行统计分析以评估年龄、性别、地点和季节等风险因素。
在799个样本中，从统计学上看，23.0%的样本[病原体名称未给出]抗体检测呈阳性，绵羊的血清阳性率为18.4%，山羊为32.4%。年龄被确定为绵羊的一个重要风险因素，年龄较大的绵羊血清阳性率较高，而山羊未发现显著风险因素。其他变量，如性别、地点和季节，未显示出显著关联。
本研究是该国首个针对小反刍动物的研究，揭示了卡塔尔绵羊和山羊在[病原体名称未给出]流行率方面的显著差异。年龄是绵羊的关键风险因素，但需要进一步研究以探索其他因素，特别是山羊中的因素。
