牦牛布鲁氏菌病流行病学调查报告

Epidemiological Investigation Report of Brucellosis in Yak

牦牛布鲁氏杆菌病是高原地区易发生的一种细菌性传染性疾病和人畜共患病,它是由布鲁氏杆菌感染引发,属于慢性传染性疾病,临床上主要以持续的发热、多汗、关节疼痛、肝脏肿大、反复发作为主要特征,该种疾病在青海省化隆县以春末夏初多见。患病牛是主要的传染源,可经接触感染或者消化道感染,也可通过呼吸道传播,人对该种病菌具有易感性,感染后会造成机体免疫功能下降。为更好地掌握布鲁氏杆菌病在青海省化隆县的流行发生现状,2018年调查该县的牦牛1 300头,间接ELISA检测检测结果显示阳性的有6头,阳性率0.46%,血清检测阳性7头,阳性率为0.54%,尽管所在地区的牦牛布鲁氏杆菌病的发病率相对较低,但是防控压力影响巨大,需要采取针对性措施进行防控。

Yak brucellosis is a bacterial infectious disease and zoonotic disease that is more likely to occur in plateau areas.It is caused by brucella infection and is a chronic infectious disease.It is mainly clinically characterized by continuous fever and multiple diseases.Sweat,joint pain,and liver enlargement are the main features. This disease is more common in Hualong county,Qinghai province in late spring and early summer.Sick cows are the main source of infection,which can be infected by contact or gastrointestinal infection,or spread through the respiratory tract.Humans are susceptible to this kind of bacteria,and the infection will cause the body’s immune function to decline.In order to better grasp the prevalence of brucellosis in Hualong county,Qinghai province,1 300 yaks in the county were investigated in 2018.Indirect ELISA test results showed that 6 of them were positive with a positive rate of 0.46%.Seven were positive,with a positive rate of 0.54%.Although the incidence of yak brucellosis in the region is relatively low,the pressure on prevention and control has a huge impact,and we need to take targeted measures to prevent and control.
