牦牛脑包虫病临床症状及治疗

Clinical Symptoms and Treatment of Cerebral Hydatid Disease in Yak

牦牛脑包虫病被称为脑多头蚴病,是带状的多头绦虫的中绦期幼虫寄生在牦牛大脑和脊髓中引发的一类体内寄生虫疾病。多头蚴大多呈现包囊状,有的呈豌豆大小,有的呈鸡蛋大小,包囊中充满大量的液体,内膜上附着很多的多头蚴。犬科类动物如狼、狐狸和狗是脑包虫病的终末宿主。放牧养殖模式下,牦牛接触犬科类动物和犬科类动物粪便的几率极大增强,通过饮食渠道将多头蚴吃入体内,最终造成脑包虫病的发生流行。该文探讨牦牛脑包虫病的治疗与防治,对更好地控制该类体内寄生虫疾病的发生流行。

Yak echinococcosis,also known as polycephalosis,is an internal parasitic disease caused by the larva of the polytaenia zoster in the brain and spinal cord of yaks during the middle taenia stage.Most of the metacercariae are cysts,some are peasized,some are egg-sized,the cysts are filled with a lot of fluid,and there are many metacercariae attached to the inner membrane.Canids such as wolves foxes and dogs are the final hosts of cerebral hydatid.Under the grazing and breeding mode,the chances of yaks contacting canine animals and canine feces are greatly increased,and they often eat metacercariae into the body through dietary channels,and eventually cause the epidemic of cerebral hydatidosis.In this study,we discussed the treatment and prevention of yak cerebral hydaticosis based on the incidence of a breeding farm,hoping to better control the occurrence and prevalence of this kind of parasitic diseases.
