Sera from butcher swine (1,246 total) were evaluated qualitatively by the microimmunodiffusion test and quantitatively by the virus neutralization test for antibody to pseudorabies virus. Ten percent of the sera had antibody to pseudorabies virus. Follow-up contact with veterinarians whose clients included the farms from which the positive swine originated revealed that few feeder swine are vaccinated against pseudorabies and that most infections with pseudorabies virus are subclinical.
对来自屠宰猪(共1246头)的血清进行了伪狂犬病病毒抗体的微量免疫扩散试验定性评估和病毒中和试验定量评估。10%的血清含有伪狂犬病病毒抗体。对其客户包括阳性猪来源农场的兽医进行随访发现,很少有育肥猪接种伪狂犬病疫苗,而且大多数伪狂犬病病毒感染是亚临床的。
