猪旋毛虫病流行病学与诊断

Epidemiology and Diagnosis of Swine Trichinosis

猪旋毛虫病是由毛尾属的旋毛虫感染生猪肠道所引发的一种体内寄生虫病,是国家二类传染性疾病。幼虫主要寄生在猪的横纹肌中,人、猪、犬科类动物、猫科类动物均能感染该种寄生虫,人感染旋毛虫后可以诱发死亡。由于该类疾病是一种人畜共患病,如果不能做好有效防范工作,很容易通过食物链进入人类体内,威胁人们的生命财产安全。该类寄生虫病的传播途径多样,在生猪养殖产业发展中,需要养殖户构建多样化的防范措施,切断传染源和传播途径,保护易感群体。该文主要论述猪旋毛虫病的流行病学、临床症状、病理变化、诊断方法和防治手段。

Trichinosis is an internal parasitic disease caused by the intestinal infection of pigs with trichinella of the genus infectious disease.The larvae are mainly parasitized in the rhabdomyus muscle of pigs.Humans,pigs,canids and cats can all be infected with the parasite,and human death can be induced by trichinella spiralis infection.Because the disease is a kind of zoonosis,if do not do effective prevention work,it is easy to enter the human body through the food chain,threatening people's lives and property security.In the development of pig breeding industry,it is necessary for farmers to construct various preventive measures,cut off the source of infection and the way of transmission,and protect susceptible groups.In this paper,the epidemiology,clinical symptoms,pathological changes,diagnostic methods and control methods of swine trichinosis were discussed.
