The apicomplexan protozoan parasite Toxoplasma gondii is a widely distributed etiological agent of foodborne illness. This parasite can cause production losses in livestock and serious disease in humans through consumption of contaminated meat. Pig meat is the most likely source of human infection, and wild boars may play a role in the transmission of T. gondii by serving as a reservoir host. This study aimed to investigate the seroprevalence of antibodies to T. gondii among farmed wild boars in China. In an 11-month survey, a total of 882 serum samples were obtained from farmed wild boars from three cities (Jilin City, Siping City, and Baishan City) in Jilin province, Northeast China and were tested for antibodies specific for T. gondii. Using modified agglutination test and a cutoff titer of 1:25, the prevalence of T. gondii infection in the examined samples was 10.0% (88 of 882). The highest seroprevalence was observed in animals from Jilin city (15.3%, 43/281) and followed by Siping (11.4%, 30/263) and Baishan (4.4%, 15/338). Logistic regression analysis revealed a significant correlation between the investigated geographic region and T. gondii infection. In addition, prevalence was higher in females compared to males, and the highest prevalence was detected in piglets. These findings indicate that farmed wild boars may become a source of foodborne toxoplasmosis, posing a food safety threat to the public health in the investigated areas. Implementation of effective measures to control T. gondii infection in farmed wild boars in China may be warranted.
顶复门原生动物寄生虫刚地弓形虫是食源性疾病广泛传播的病原体。这种寄生虫可通过食用受污染的肉类导致家畜生产损失和人类严重疾病。猪肉是人类感染的最可能来源，野猪可能作为储存宿主在弓形虫传播中发挥作用。本研究旨在调查中国养殖野猪中弓形虫抗体的血清流行率。在一项为期11个月的调查中，从中国东北吉林省的三个城市（吉林市、四平市和白山市）的养殖野猪中总共采集了882份血清样本，并检测了针对弓形虫的特异性抗体。使用改良凝集试验和1:25的临界滴度，在所检测的样本中弓形虫感染率为10.0%（882份样本中的88份）。在吉林市的动物中观察到最高血清流行率（15.3%，43/281），其次是四平（11.4%，30/263）和白山（4.4%，15/338）。逻辑回归分析显示所调查的地理区域与弓形虫感染之间存在显著相关性。此外，雌性的流行率高于雄性，仔猪中检测到的流行率最高。这些发现表明养殖野猪可能成为食源性弓形虫病的来源，对所调查地区的公众健康构成食品安全威胁。在中国实施有效措施控制养殖野猪中的弓形虫感染可能是必要的。
