VTT的音标

To explore the potential use of VTT as a live vaccine vector, we have generated three modified VTT strains ( MVTTs) by homologous recombination with the green fluorescent protein ( GFP) gene at three distinct genomic locations.

为了开发天坛株作为活载体来构建疫苗，我们通过同源重组的方法将绿色荧光蛋白基因GFP导入到其基因组的不同位置，构建了三种改良的痘苗病毒天坛株。

We found that VTT has broad host cell range that 11 of the 12 mammalian cell lines studied and primary CEF are permissive to VTT infection whereas one, CHO-K1, is non-permissive.

我们发现天坛株具有广泛的宿主范围，经研究的12种哺乳动物细胞中的11种及原代鸡胚细胞CEF均是天坛株的允许细胞，而中国仓鼠卵巢细胞CHO-K1是天坛株的非允许细胞。

We have previously characterized the phenotypic properties of VTT both in vitro and in vivo and have identified its virulence property in causing the body weight loss in mice once inoculated directly through the intracranial route.

之前我们已经鉴定了野生型天坛株在体内体外的生物学特性，并且已经通过检测鼻腔途径导致的体重降低和直接颅腔接种鉴定了其毒力。
