在日本，由于最近广泛的根除计划的成功，大多数猪群现在都没有伪狂犬病毒（PRV）。然而，PRV感染在日本野猪（白斑野猪）中持续存在，这代表了日本另一个潜在的病毒库。在本研究中，确定了在三个不同的县捕获的野猪中PRV的血清阳性率。病毒中和（VN）试验显示，173份血清样品中有6份（3%）VN抗体阳性；糖蛋白E-ELISA检测显示感染的是野生型PRV，而不是现有的疫苗株。这些结果表明，PRV在日本野猪中继续传播。
In Japan, most pig populations are now free from pseudorabies virus (PRV) due to the recent success of an extensive eradication program. However, PRV infection persists in Japanese wild boars (Sus scrofa leucomystax), representing another potential reservoir for the virus in Japan. In this study, the seroprevalence of PRV in wild boars captured in three different prefectures was ascertained. A virus neutralization (VN) test showed that 6 of 173 serum samples (3%) were positive for VN antibody; glycoprotein E-ELISA revealed infection with the wild-type, but not the available vaccine strain, PRV. These results indicate that PRV has continued to spread among wild boars in Japan.
