摘　　要：弓形虫可以感染多种动物和人导致人兽共患弓形虫病。猪感染弓形虫后不仅影响其自身的发育、繁殖,对养殖业发展造成一定的经济损失,若以感染猪来源的肉制品为食物,还可能威胁到其他动物和人类的健康。猪弓形虫感染受多种因素(年龄、猪场管理及外界环境中猫、鼠的存在等)的影响,不同地区的猪弓形虫感染的风险因素不同;弓形虫在遗传上有多样性,不同地区的猪感染弓形虫的基因型不同。论文对国外的猪弓形虫感染的风险因素及基因型的研究进展进行了综述。Toxoplasmosis is a worldwide zoonosis caused by Toxoplasma gondii which can infect human and almost all warm-blooded animals.Infection in pigs not only results in significant reproductive and eco-nomic losses,but also represents an important source of human and other animal infections due to con-sumption of infected meat.The risk factors associated with T.gondii infection are age,management,lack of rodent control and presence of cats,et al.Different factors were observed among different regions.T. gondii is genetically and biologically divergent.There are different genotypes of T.gondii from pigs in different regions.In the present paper,research progress on the risk factors and genotyping of T.gondii from pigs in foreign countries were reviewed.
