Beef cattle and calves in four Illinois populations were studied. Serum was tested by the hemagglutination-inhibition (HI) test for antibodies to parainfluenza viruses (PIV) 1, 2, and 3. In all but group 3 a low level of antibody to PIV-1 and 2 was demonstrated. The highest prevalence and incidence of HI-antibodies was found for PIV-3, followed by PIV-1. There may have been a cross-reaction between PIV-1 and -3 in Group 1 calves. The low level of HI antibodies to PIV-1 and 2 may have resulted from infections early in life or colostral antibodies that decreased with age.
对伊利诺伊州四个群体的肉牛和犊牛进行了研究。通过血凝抑制（HI）试验检测血清中针对副流感病毒（PIV）1、2和3的抗体。除第3组外，所有组均显示出针对PIV - 1和2的低水平抗体。发现PIV - 3的HI抗体患病率和发病率最高，其次是PIV - 1。第1组犊牛中PIV - 1和 - 3之间可能存在交叉反应。针对PIV - 1和2的HI抗体水平较低可能是由于生命早期感染或随年龄下降的初乳抗体所致。
