牦牛坏死梭杆菌感染病流行与防控

Epidemic and Control of Fusobacterium Necrophorum Infection in Yak

牦牛坏死杆菌病是高原地区牛养殖业中发病率较高的一类细菌性传染性疾病。牛感染坏死杆菌后,通常呈慢性感染,如果治疗不及时,会影响牛群生长发育,造成生长发育迟缓,身体消瘦,生产性能下降,严重的可以造成内脏器官坏死,呈现败血症经过,引发大量死亡。由于坏死杆菌寄生条件十分多样,感染途径较多,如果没有做好综合养殖管理工作,在放牧养殖过程中,很容易造成群体发病,威胁牛群正常生长发育。该文主要分析牦牛坏死杆菌病的流行特点、临床症状、病理变化、诊断方法和防控措施。

The yak necrobacillosis is a kind of bacterial infectious disease which has a high incidence in cattle breeding industry in plateau area.Cattle infected with necrotising bacilli are usually chronically infected.If not treated in time,it will affect the growth and development of cattle,resulting in growth retardation,emaciation of the body,reduction of production performance,and in severe cases,necrosis of internal organs,and presentation of septicemia,causing a lot of death.Because of the variety of parasitic conditions and infection ways,if the integrated breeding management is not well done,it is easy to cause group disease and threaten the normal growth and development of cattle.This paper mainly analyzes the epidemic characteristics,clinical symptoms,pathological changes,diagnostic methods and control measures of yak necrobacillosis.
