1) PRRS attenuated strain
PRRS弱毒株
1.
In order to investigate local respiratory tract and system immune reaction, PRRS attenuated strain were used to immune pigs by nasal and muscle injection route.
本试验应用PRRS弱毒株分别通过鼻腔免疫和肌肉注射免疫长×大二元杂交猪,研究呼吸道局部免疫反应和系统免疫反应的变化。
2) PRRS live virus vaccine
PRRS弱毒苗
1.
The research was to study the effects of indigowoad root polysaccharide (IRPS) on antibody and T subpopulations in piglets peripheral blood in the immune response to PRRS live virus vaccine.
弱毒苗免疫后7d,板蓝根多糖高剂量组即可检测到PRRSV阳性抗体,而其它组在免疫后14d,均可检测到PRRS阳性抗体,板蓝根多糖对PRRS弱毒苗产生抗体的影响是和剂量密切相关的,高剂量能提高抗体水平,低剂量会阻碍PRRSV抗体的产生。
3) weak potent vaccine PRRSV
PRRS弱毒疫苗
4) attenuated strain
