MSB-1培养物上清液对体内MDV作用的研究

Effect of CellFree MSB1 Cultural Supernatant to MDV Pathogenicity in vivo

研究了马立克氏病肿瘤细胞系（ＭＳＢ－１）培养物上清液对体内鸡马立克氏病病毒（ＭＤＶ）增殖的影响，结果表明，该上清液对体内ＭＤＶ的增殖无明显抑制作用；相反，可增加ＭＤ的发病率。另外，试验中发现，６日龄鸡对ＭＤＶ的易感性明显高于１日龄鸡。

An experiment was conducted for studying the effect of cellfree MSB1 cultural supernatant to Mareks disease virus (MDV) pathogenicity in viro As a result,the supernatant didn’t inhibit the MDV propagation in viro,so far,it could enhancce the incidence of MDBesides we noted that 6dayold birds were more susceptible to MDV than 1dayold birds.
