vaccinia

基本解释

However, a virus called vaccinia spreads four times faster than what was thought possible.
然而，一种名为牛痘的病毒传播的速度比我们所能想像的快四倍。
Just after vaccinia infects a cell, it expresses two viral proteins on the cell surface, which marks the cell as infected.
牛痘刚感染一个细胞后，就在细胞表面显示出两个病毒蛋白，这表明细胞已经感染。
Under normal conditions, vaccinia spread across one cell every 1.2 hours, which was slowed to one cell every five to six hours.
正常条件下，牛痘病毒每1.2小时传遍一个细胞，而现在减慢至每五六小时传遍一个细胞。

We know now that it's caused by a related virus, called vaccinia, remember the virus that causes smallpox is called variola.
我们现在知道这病由一种相关的病毒引起,这种病毒叫牛痘病毒,想想天花病毒也被叫做牛痘病毒

So, how could you produce--the question is, how could you produce large quantities of this- of this microorganism, this virus vaccinia under controlled conditions?
问题是该怎么进行生产,你怎么大批量生产这种微生物,即在可控条件下生产牛痘病毒

Well, it turns out that we could not identify, at least at that point, a cell culture that would serve as a host for vaccinia.
然而我们还不能断定,至少这个时候无法断定,这些被感染的细胞就是牛痘病毒的宿主

In this case, a little genetic engineering convinced vaccinia to produce an important rabies antigen.
