摘要
以出生2日龄的正常长白仔猪尾尖组织为材料,通过组织消化法培养获得原代尾尖成纤维细胞。并通过间接免疫荧光法,梯度10倍倍比稀释猪瘟病毒石门株(105.2 TCID50/mL)感染在猪尾尖成纤维细胞,确定尾尖成纤维细胞最佳病毒感染滴度。结果显示,运用组织块消化法能够获得生长状态的原代猪尾尖成纤维细胞,并且细胞对10-3稀释倍数的猪瘟病毒石门株具有适中的感染力。
In order to establish the mature pigtail-tip fibroblast cell isolation system and to evaluate its susceptibility to classical swine fever virus （CSFV） was Shimen strain, 2-day-old newborn Landrace pigs pigtail tip as the tissue material,and obtained primary fibroblasts of the pig tail-tip by organization digestion method, then used indirect immunofluorescence method to determine the fibroblasts susceptibility to the virus（105.2 TCID50/mL） in a gradient dilution testing. Our results showed that organization digestion method can able to obtain pig tail tip fibroblast cells grow in good condition and it is proper susceptibility to CSFV Shimen strain with 10.3 fold dilution of vi- rus stock solution.
