vaccinia

基本解釋

However, a virus called vaccinia spreads four times faster than what was thought possible.
然而，一種名為牛痘的病毒傳播的速度比我們所能想像的快四倍。
Just after vaccinia infects a cell, it expresses two viral proteins on the cell surface, which marks the cell as infected.
牛痘剛感染一個細胞后，就在細胞表面顯示出兩個病毒蛋白，這表明細胞已經(jīng)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.
正常條件下，牛痘病毒每1.2小時傳遍一個細胞，而現(xiàn)在減慢至每五六小時傳遍一個細胞。

We know now that it's caused by a related virus, called vaccinia, remember the virus that causes smallpox is called variola.
我們現(xiàn)在知道這病由一種相關(guān)的病毒引起,這種病毒叫牛痘病毒,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?
問題是該怎么進行生產(chǎn),你怎么大批量生產(chǎn)這種微生物,即在可控條件下生產(chǎn)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.
然而我們還不能斷定,至少這個時候無法斷定,這些被感染的細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.
