Abstract

Serum samples were collected from 254 yak (Poephagus grunniens, presently Bos grunniens) in different yak tracts of India. These samples were then screened by virus neutralisation test (VNT) and avidin-biotin enzyme-linked immunosorbent assay (AB-ELISA) to study the seroprevalence of antibodies against bovine herpesvirus type 1 (BHV-1). The overall seroprevalence in yak was found to be 41% (105) by VNT and AB-ELISA. The sex of the animal, whether it was on a farm or free-ranging and the location of the different yak tracts did not seem to have any effect on seroprevalence. However, seroprevalence was found to increase with the age of the animals, being highest in yak older than three years of age (49%). Yak generally share feeding, watering and grazing areas with other domestic and wild animals and this common ecological niche is thought to be a possible avenue of infection. This is the first time that the seroprevalence of antibodies against BHV-1 has been studied in yak in India.

摘要

从印度不同牦牛分布区的254头牦牛（牦牛属，现称牛属）采集血清样本。然后通过病毒中和试验（VNT）和抗生物素蛋白-生物素酶联免疫吸附测定（AB-ELISA）对这些样本进行筛查，以研究抗1型牛疱疹病毒（BHV-1）抗体的血清流行率。通过VNT和AB-ELISA发现牦牛的总体血清流行率为41%（105头）。动物的性别、是否在农场饲养或自由放养以及不同牦牛分布区的位置似乎对血清流行率没有任何影响。然而，发现血清流行率随动物年龄增加而升高，三岁以上的牦牛血清流行率最高（49%）。牦牛通常与其他家养和野生动物共享觅食、饮水和放牧区域，这种共同的生态位被认为是可能的感染途径。这是首次在印度牦牛中研究抗BHV-1抗体的血清流行率。
