Borna disease virus (BDV) is a neurotropic virus with a broad host and geographic range. Lewis rats were immunized against BDV with a recombinant vaccinia virus expressing the BDV nucleoprotein and were later infected with BDV to evaluate protection against Borna disease (BD). Relative to animals that were not immunized, immunized animals had a decreased viral burden after challenge with infectious virus, more marked inflammation, and aggravated clinical disease. These data suggest that a more robust immune response in Borna disease can reduce viral load at the expense of increased morbidity.
博尔纳病病毒(BDV)是一种嗜神经性病毒,具有广泛的宿主范围和地理分布。用表达BDV核蛋白的重组痘苗病毒对Lewis大鼠进行BDV免疫,随后用BDV感染大鼠,以评估对博尔纳病(BD)的保护作用。与未免疫的动物相比,免疫动物在感染传染性病毒后病毒载量降低,炎症更明显,临床疾病加重。这些数据表明,博尔纳病中更强有力的免疫反应可降低病毒载量,但代价是发病率增加。
