Humans are the hosts that plasmodium feed off of.

人类是赖以生存宿主。

The Malaria parasite is called Plasmodium.

疾寄生被称为。

We think that these parasites are going to be extremely difficult to stop.

我们认为这种将会很难得到控制。

The parasites have a tougher time developing when mosquitoes are too warm.

蚊子体温过高时，很难发育。

I'm talking about Plasmodium, which causes malaria.

我说是，牠会导致疾。

These are real parasites as recently exposed to humans.

这些是最近才在人类身上出现。

Such trends may not have any relevance to the malaria parasites that infect humans.

这种趋势与感染人类可能没有任何关系。

Hemozoin crystals are not found in red cells that are not infected with malaria.

未感染疾红细胞中不存在色素晶体。

What it does do is decrease the severity of infection by Plasmodium falciparum malaria.

镰状细胞特征作用是减轻恶性感染性。

Malaria is caused by plasmodium parasites, which are transmitted by mosquitoes.

疾是由这种寄生引发并靠蚊子传播。

It does that by interacting with a chemical receptor on the surface of the cell.

是通过跟血细胞表面化学感受器交流来进入血细胞。

One critical point in that process is when the parasite enters the victim's red blood cells.

一个关键点就是进入宿主血细胞时候。

Malaria parasites don't seem to fare as well in red blood cells when less of the enzyme is around.

在少量酶扩散时候，在血红细胞中也保持良好。

There has been some reduction in the proportion of people who are likely to be affected with the falciparum parasite.

可能感染上镰状人口比例已经下降。

So we think that this will provide additional impetus for grossly intensifying the malaria elimination efforts in Southeast Asia.

对于消灭东南亚，人们还需要加强努力。

Malaria is caused by a parasite called Plasmodium, which is transmitted through the bite of an infected female mosquito.

疾是由名为寄生引发，这种寄生通过感染母蚊叮咬传播。

And when artemisinin encounters hemozoin, the two compounds react to create unstable atoms known as free radicals.

当青蒿素遇到色素时，这两种化合物会发生反应，产生被称为自由基不稳定子。

But luckily, artemisinin reacts more readily with hemozoin, than it does with the iron in our cells.

但幸运是，青蒿素与色素反应比与我们细胞中铁反应更容易。

Once they mature, these parasites contain a compound called hemozoin — something they ultimately get from digesting human blood.

这些寄生成熟之后会含有一种叫做色素化合物——这是它们从消化人类血液中获得东西。

The vaccine tries to stop one type of malaria parasite, Plasmodium falciparum, before it has a chance to wreak havoc.

该疫苗能停止疾寄生恶性活性，使它不能为非作歹。
