类NADC30猪繁殖和呼吸综合征病毒（PRRSV）在我国广泛传播，并在部分省份成为局部优势病毒株。尽管它不像2006年以来暴发的高致病性PRRSV（HP-RRRSV）那样具有致病性，但类NADC30 PRRSV以与其他病毒毒株重组发生率高，导致毒力的改变而闻名。在接种疫苗的猪群中暴发 ...

猪繁殖与呼吸综合征病毒（Porcine reproductive and respiratory syndrome virus，英文简称PRRSV）不仅会引起妊娠母猪繁殖障碍以及各阶段猪只呼吸道疾病，因其还是一种具有免疫抑制作用的病毒，所以PRRSV可能会加剧细菌感染，改变抗生素的药代动力学，并可能导致抗生素 ...
