The serological studies reported in the present paper were done on forty-one pig-breeding farms contaminated with Aujeszky's disease and four farms that were free from this disease and on which fifty per cent of the animals had been inoculated with the Bartha vaccine. The serological studies were based on the serum neutralization test (SN test). On contaminated farms, the majority of the animals present at the time of outbreak of the disease were serologically positive. Comparison of the serological findings on farms on which there had been outbreaks of the disease from two to seven and from seven to twelve months previously, showed that there was hardly any difference in titre levels between the two groups. Of twenty-eight breeding boars used for service at the time of the outbreak, twenty-one per cent were serologically negative. Serological studies in breeding gilts showed that virulent virus was only transmitted up to two months after the outbreak of the disease.
本文报道的血清学研究是在41个感染了奥耶斯基氏病的养猪场以及4个未感染该病且50%的动物接种了巴塔疫苗的农场进行的。血清学研究基于血清中和试验（SN试验）。在受污染的农场，疾病爆发时在场的大多数动物血清学呈阳性。对疾病爆发前两至七个月以及七至十二个月的农场血清学结果进行比较，结果显示两组之间的滴度水平几乎没有差异。在疾病爆发时用于配种的28头种公猪中，21%血清学呈阴性。对后备母猪的血清学研究表明，强毒病毒仅在疾病爆发后两个月内传播。
