羊传染性胸膜肺炎流行特点及防治

Epidemic Characteristics and Prevention of Sheep Infectious Pleuropneumonia

羊传染性胸膜肺炎是由肺炎支原体感染引发的一种接触性疾病,该种疾病在羊群中传播速度较快,感染范围较广,不同年龄品种的羊都会受到病原感染,常呈地方性流行。新发病的养殖场发病较急,发病过程较短,老疫区常呈慢性感染、周期性感染。传染性胸膜肺炎一旦发生流行,将需要消耗较多的时间和精力用于羊群净化处理,否则隐性感染羊会频繁和健康羊接触,造成发病率较高。该文探讨羊传染性胸膜肺炎的流行特点和防治措施。

Sheep infectious pleuropneumonia is an acute and chronic contact disease caused by mycoplasma pneumoniae infection.The disease spreads quickly in sheep and has a wide range of infections.Sheep of different ages and breeds will be infected by the pathogen and often appear in local areas.Newly-infected farms have a more rapid onset and a shorter course of onset.Chronic infections and periodic infections are often present in old epidemic areas.Once infectious pleuropneumonia occurs,it will take more time and energy to purify the sheep,otherwise the latent infected sheep will frequently come into contact with healthy sheep,resulting in a higher incidence.This article discusses the epidemiological characteristics and prevention measures of infectious pleuropneumonia in sheep.
