vaccinia

基本解釋

However, a virus called vaccinia spreads four times faster than what was thought possible.
然而，一種名爲(wèi)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(xì)胞後，就在細(xì)胞表麪顯示出兩個病毒蛋白，這表明細(xì)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(xì)胞，而現(xiàn)在減慢至每五六小時傳遍一個細(xì)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?
問題是該怎麼進行生産,你怎麼大批量生産這種微生物,即在可控條件下生産牛痘病毒

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(xì)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.
