包虫病(棘球蚴病)是人体感染棘球绦虫幼虫(又称包虫)引起的疾病。在我国共有两种:一种为细粒棘球绦虫幼虫引起者,称为囊型棘球蚴病,以狗为终宿主,羊为主要中间宿主,在狗与羊中间传播。人若吞食其虫卵,成为其中间宿主,引起囊型棘球蚴病。另一种为多房棘球绦虫幼虫引起者,称为泡型棘球蚴病,在自然界以野狗、狐、狼等为终宿主,被其捕食的啮齿动物如田鼠为中间宿主。人吞食其虫卵后,成为中间宿主,引起泡型棘球蚴病。
Echinococcosis (hydatid disease) is a disease caused by human infection of Echinococcus taenia larvae (also known as hydatid). There are two kinds in our country: One is caused by Echinococcus granulosus larvae, known as cystic echinococcosis, the dog is the ultimate host, the sheep as the main intermediate host, in the middle of dogs and sheep spread. If people devour their eggs, become its intermediate host, causing cystic echinococcosis. The other is caused by larvae of Echinococcus multilocularis, known as alveolar hydatid disease, in the wild dog, fox, wolf, etc. as the final host, by its prey rodents such as voles as the intermediate host. After swallowing its eggs, it becomes an intermediate host and causes alveolar echinococcosis.
