舍饲绵羊支原体肺炎诊断与防治

摘要：绵羊支原体肺炎是由肺炎支原体引发的绵羊特有的高度接触性传染性疾病。该种疾病被世界卫生组织划归为B类疫病，我国将其划归为二类动物疫病，临床上以纤维素性肺炎和胸膜肺炎为主要特征。舍饲养殖模式下，由于单位面积内的羊群养殖数量相对较多，不同年龄的羊群在相互接触中，由于抗病能力存在一定差异，易传播多种病原。不同性别和年龄的绵羊遭受到支原体危害后，表现的临床症状存在一定差异性。隐性患病病例的存在使养殖场反复流行该类疾病，造成的危害巨大。该文主要论述舍饲绵羊支原体肺炎的诊断和防治过程，以降低经济损失，提高治疗效果。

Diagnosis，Prevention and Treatment of Mycoplasma Pneumonia in House-fed Sheep

Abstract：Mycoplasmal pneumonia of the sheep is an acute，chronic，highly contagious infectious disease characteristic of sheep，caused by Mycoplasma PNEUMONIAE.The disease is classified as a class B epidemic disease by the World Health Organization and a Class II animal epidemic disease in China，with fibrinous pneumonia and pleuropneumonia as the main clinical features.Due to the relatively large number of sheep in a unit area，the disease-resistant ability of different age sheep is different，and it is easy to spread many kinds of pathogens.The clinical symptoms of bank right of different sex and age are different when they are harmed by mycoplasma.Because of the existence of hidden disease cases，the disease has been prevalent in the farm repeatedly，resulting in great harm.This paper mainly discusses the diagnosis and treatment process of mycoplasma pneumonia in sheep，in order to reduce the economic loss and improve the treatment effect.

引言

绵羊支原体肺炎又被称为绵羊传染性胸膜肺炎和烂肺病，是由肺炎支原体感染引发的以咳嗽、气喘、渐行性消瘦和肺间质增生性炎症为主要特征的接触性呼吸道疾病。临床上患病羊表现为咳嗽、流出脓性鼻液、身体逐渐消瘦、严重贫血、生长发育不良，发病较为缓慢，造成的死亡率较低，但是会造成出栏率和羊毛质量显著下降，并使饲料和人力成本大量浪费。很多养殖场在引种中不能严格落实引种检疫和隔离观察，造成携带病菌的羊群引入养殖场，引发新疫病流行。需要提高重视程度，加强支原体肺炎的流行病学调查，持续进行羊群净化，发现带菌羊及时处理，培养健康羊群，降低经济损失。……
