Toxoplasmosis is a disease caused by the protozoan Toxoplasma gondii which infects most genera of warm-blooded animals, including humans. The objective of this investigation is to evaluate the seroprevalence of toxoplasmosis in pigs in Chongqing Municipality, southwest China. Slaughterhouse pigs' serum samples collected from six different regions in Chongqing were assayed for T. gondii antibodies by an indirect hemagglutination test. The average seroprevalence of T. gondii were found in 30.6% (278/908) in slaughter pigs, ranging from 21.6% to 40.9% among different sampling sites. The results indicated that toxoplasmosis in swine of Chongqing Municipality was relatively serious, and the pork may be an important source for human infection with T. gondii. Comprehensive measures are needed to strengthen further prevention and control of the disease in Chongqing.
弓形虫病是一种由原生动物刚地弓形虫引起的疾病，该寄生虫可感染包括人类在内的大多数温血动物属。本调查的目的是评估中国西南部重庆市猪群中弓形虫病的血清流行率。通过间接血凝试验对从重庆六个不同地区采集的屠宰场猪血清样本进行刚地弓形虫抗体检测。结果发现，屠宰猪中弓形虫的平均血清流行率为30.6%（278/908），不同采样点的流行率在21.6%至40.9%之间。结果表明，重庆市猪群中的弓形虫病较为严重，猪肉可能是人类感染刚地弓形虫的重要来源。需要采取综合措施进一步加强重庆市该病的预防和控制。
