摘　　要：[目的]为了解内蒙古奶牛昏睡嗜血杆菌(Hs)的感染状况。[方法]调查12个盟(市)23个旗(县)的65个奶牛场,包括大型规模化奶牛场20个、小型规模化奶牛场21个、家庭牧场24个。采集2 650份阴道拭子样品,用荧光PCR方法检测Hs。[结果]除乌海市以外,其余11个盟(市)均出现Hs阳性场。在23个旗(县)中,只有7个未检出阳性场,其余16个均检出阳性场,阳性旗(县)比例高达69.6%。大型规模化奶牛场、小型规模化奶牛场和家庭牧场个体阳性率分别为:18.2%(182/1 000)、22.9%(240/1 050)和21.2%(127/600);农区、牧区、半农半牧区、阳性率分别为:15.6%(109/700)、13.5%(135/1000)和32.1%(305/950),平均个体阳性率为20.7%(549/2 650)。[结论]内蒙古奶牛场Hs感染普遍,应加大防控力度。[Objective]To understand the infectious status of Histophillus somni(Hs)in cows in Inner Mongolia.[Method]65 dairy farms in 23 counties of 12 prefecture-level cities were investigated,including 20 large-scale dairy farms,21 small-scale dairy farms and 24 family farms.2650 vaginal swabs were collected to detect Hs DNA by fluorescent PCR.[Result]The results showed that 11 cities had positive cases of Hs except for Wuhai City.Moreover,16 of 23 counties have been detected positive cases except for 7 negative counties and the proportion of positive counties was as high as 69.6%.The individual positive rates of large-scale dairy farms,small-scale dairy farms and family farms were 18.2%(182/1000),22.9%(240/1050)and 21.2%(127/600),respectively,and the positive rates of agricultural areas,pastoral areas and farming-pastoral areas were 15.6%(109/700),13.5%(135/1000)and 32.1%(305/950),respectively.The average individual positive rate was 20.7%(549/2650).[Conclusion]This study indicatd that Hs infection was very common in dairy farms in Inner Mongolia,prevention and control should be strengthened.
