摘  要
近年來，城鄉(xiāng)養(yǎng)豬的數量不斷的增加，豬的傳染病也隨之增加，由其以豬的大腸桿菌病為主的腸道腹瀉病，給人類健康和養(yǎng)豬業(yè)的發(fā)展帶來了極大的危害。豬的大腸桿菌病是由豬的大腸桿菌引起的豬的一種急性、熱性、高度接觸性傳染病。以白細胞減少、急性卡他炎、嚴重胃腸炎主要特征。病毒寄生廣泛，以通過接觸傳播，傳染性強，發(fā)病率高，發(fā)病急，仔豬易發(fā)病。一旦發(fā)病，常呈現(xiàn)大流行，易死亡的特點。從而給養(yǎng)豬業(yè)以及豬主人帶來巨大身心損害。該病作為豬的重要傳染病之一，本論文從病原的病理變化，診斷，防治等幾個方面對豬的大腸桿菌病作簡要的論述。

Abstract
In recent years, the number of pigs and unceasing increase of infectious diseases, the pig also increased, with it by the heat of the virus disease, mainly to human health, and raises the development of industry has brought great harm. It is hot by canine distemper virus get canine distemper virus (caused), pig an acute, heat, high contact sexually transmitted diseases. With dual phase heat, leukopenia, acute card, bronchitis and his severe neurologic symptoms gastroenteritis, main features. Viruses, through extensive contact with parasites, infectious disease, strong, a high incidence of yi, puppies. Once the pathogenesis, often appear pandemic, easy to death. Thus supplies canine pig owners bring huge and physical damage. The disease is one of the important diseases as pigs, this thesis pathogen pathological changes, diagnosis, prevention and control of ReZuo it several aspects in this paper.
