Serological examination of 4 Border disease affected flocks of sheep using the neutralization test showed antibody prevalences between 14 and 96 %. Prevalence in yearlings in 3 of the 4 flocks was 37 , it increased with age to 72 % in 5-year-old sheep. Possible reason for low prevalence (2 %) in yearlings in one of the flocks is discussed.
使用中和试验对4个感染边境病的绵羊群进行血清学检查,结果显示抗体阳性率在14%至96%之间。4个羊群中有3个羊群的一岁羊阳性率为37%,随着年龄增长,5岁羊的阳性率增至72%。文中讨论了其中一个羊群一岁羊阳性率较低(2%)的可能原因。
