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

我们认为这种原虫将会很难得到控制。

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

蚊子体温过高时，原虫很难发育。

I'm talking about Plasmodium, which causes malaria.

我说的是原虫，牠会导致疾。

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

这种趋势与感染人类的原虫可能有何关系。

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

未感染疾的红细胞中不存在原虫色素晶体。

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

镰状细胞特征的作用是性原虫感染的严重性。

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

疾是由原虫这种寄生虫引发并靠蚊子传播的。

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

一个关键点就是原虫进入宿主血细胞的时候。

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

原虫是通过跟血细胞表面的化学感受器交流来进入血细胞的。

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

在少量酶扩散的时候，原虫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.

可能感染上镰状原虫的人口比例已经下降。

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

对于消灭东南亚原虫，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.

疾是由名为原虫的寄生虫引发的，这种寄生虫通过感染的母蚊叮咬传播。

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

当青蒿素遇到原虫色素时，这两种化合物会发生反应，产生被称为自由基的不稳定原子。

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

但幸运的是，青蒿素与原虫色素的反应比与我们细胞中的铁反应更容易。

Now, scientists have identified a single blood cell receptor that Plasmodium absolutely needs to enter the blood cell.

如今，科学家确认了一种原虫进入血细胞所必须的感受器。

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

这些寄生虫成熟之后会含有一种叫做原虫色素的化合物——这是它们从消化人类血液中获得的东西。

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虫性原虫的活性，使它不能为非作歹。

These are real parasites as recently exposed to humans.

这些是最近才在人类身上出现的原虫。

One of the substances, the mortiamide D, efficiently neutralized the parasite of malaria.

其中一种物质，mortiamide D，有效地中和了原虫。
