摘要
为了明确青藏高原地区牦牛沙门氏菌(SE)感染情况,本研究采用ELISA双抗原夹心法,对2012~2021年采集自西藏、青海、甘肃、四川的1907份牦牛血清样品进行SE抗原检测。结果显示:1907份牦牛血清中检测出SE抗原总阳性率为22.55%(430/1907),西藏地区牦牛SE阳性率与其他地区相比较高;2012~2021年青藏高原地区牦牛血清SE抗原年阳性率分别为7.35%、46.02%、15.31%、17.68%、8.79%、19.84%、6.04%、23.64%、14.81%、39.69%;牦牛在不同海拔感染SE的阳性率分别为13.67%(2900~3400 m)、14.61%(3400~3900 m)、28.62%(3900~4400 m)、34.72%(4400 m以上);犊牛感染SE阳性率(33.33%)低于成年牦牛(40.91%);不同性别牦牛感染SE平均阳性率分别为公(23.67%)、母(21.68%);4省牦牛感染SE阳性率分别为西藏(25.88%)、青海(13.50%)、甘肃(13.33%)、四川(1.89%)。本研究结果可为了解青藏高原地区牦牛沙门氏菌病的流行情况提供参考。
In order to understand the infection status of Salmonella(SE)in yaks from Qinghai-Tibet Plateau,1907 serum samples were collected from 2012 to 2021 from Tibet,Qinghai,Gansu and Sichuan and tested usingELISA double antigen sandwich method.The results showed that total positive rate of SE antigen reached 22.55%(430/1907),of which the positive rate of SE antigen in Tibet yaks was higher than that in other areas.The annual positive rates of SE antigen in yak sera of Qinghai-Tibet Plateau were 7.35%,46.02%,15.31%,17.68%,8.79%,19.84%,6.04%,23.64%,14.81%and 39.69%for the years of 2012 to 2021,respectively.The positive rates of SE infection in yaks at different altitudes were 13.67%(2900-3400 m),14.61%(3400-3900 m),28.62%(3900-4400 m)and 34.72%(over 4400 m),respectively.In addition,the positive rate of SE infection in calves(33.33%)was lower than that in adult yaks(40.91%)and the average positive rate of SE infection in yaks with different sexes were male(23.67%)and female(21.68%),respectively.The positive rates of SE infection in yaks in 4 provinces were as follows:Tibet(25.88%),Qinghai(13.50%),Gansu(13.33%)and Sichuan(1.89%).The results of this study provided a reference for understanding the epidemiological situation ofSalmonelladisease in yaks from Qinghai-Tibet Plateau.
