摘　　要：牛恶性卡他热病是由疱疹病毒引起牛接触性热性传染病,该病主要表现持续高热,全眼炎、角膜混浊,鼻腔黏膜、口腔黏膜溃疡、糜烂,流泡沫样的口涎,大量的浆液性或黏液性鼻液,全身淋巴结肿大,该病虽呈散发形式,发病率低,但死亡率高,给养牛户造成一定损失,为防控牛恶性卡他热病提供理论与实践借鉴,通过流行病学调查,临床检查和采集病牛鼻液、唾液拭子进行聚合酶链式反应检验[1],对发生于黑龙江省明水县某肉牛散养户1头疑似恶性卡他热的3岁西门塔尔牛进行诊断,确诊为绵羊2型疱疹病毒(OHV-2)感染。Bovine malignant catarrhal fever is a contagious infectious disease caused by herpes virus.It is characterized by persistent high fever,universal ophthalmia,corneal opacity,nasal mucosa,oral mucosa ulcer,erosion,foaming mouth saliva,a large amount of serous or mucous nasal fluid,and systemic lymphadenomegaly.Although the disease is sporadic,the incidence is low,but the mortality is high.It has caused certain losses and panic to cattle farmers,and provided theoretical and practical reference for the prevention and control of bovine malignant catarrhal fever.The author conducted polymerase chain reaction(PCR)test through epidemiological investigation,clinical examination and collection of nasal fluid and saliva swabs of infected cattle[1],and diagnosed a 3-year-old Simmental cow suspected of malignant catarrhal fever in a beef cattle free-range household in Mingshui County,Heilongjiang Province.Ovine herpes virus type 2(OHV-2)infection was confirmed.
