The whole flock has coccida and whip worms.

整个鸡群都有球和。

Grencis says the findings might someday lead to a way to selectively target the worms.

格兰西斯表示，一发现可能在未来会发展出选择性清除的方式。

So that whipworms no longer mooch off us-or our microbes.

因此，再也不能从我们——或者说我们的细菌中——揩油了。

Like these little creatures called choanoflagellates.

比如做领的小生物。

Choanoflagellates eat bacteria they catch themselves.

领吃它们自己捉到的细菌。

Without that host contribution, the worms die.

没有宿主的细菌贡，就会死亡。

As we can see, choanoflagellates are single celled-organisms, but we know animals don't always have all four animal traits.

正如我们所看到的，领是单细胞生物，但我们知道动物并不总是具有所有四种动物特征。

Well, choanoflagellates have little flagella that whip back and forth to move them from place to place.

领有很小的毛，毛来回摆动，让它们从一个地方移动到另一个地方。

Grencis and his team studied that phenomenon in mice-because there's a type of whipworm adapted to them too.

格兰西斯和团队在老鼠身上研究了种现象，因为老鼠体内也有适应其生存的一种。

The whipworm is a parasite that infects half a billion people around the world.

是令全球5亿人感染的一种寄生。

Priapulids also became more common in the Cambrian.

腮在寒武纪也变得更加常见。

It takes them from the host and then bends it to generate a population which suits itself.

“从宿主身上获得细菌，使其产生适合自己的菌群。”

But the worms also induce changes in the host's microbiome-tweaking it so the gut is no longer hospitable to hatching.

但是也会诱发宿主体内菌群的变化——对菌群进行调整，使宿主肠道不再适合孵化。

Roundworm, hookworm, whipworm, schistosomiasis: infections from these species cause pain and discomfort.

蛔、钩、、血吸病：寄生引起的感染会导致疼痛和不适。

His intestines were also parasitized by whipworms and his stomach contained ulcer-causing bacteria, all of which might have caused some unpleasant symptoms.

他的肠道还寄生着，胃里也有引起溃疡的细菌，都可能引起一不愉快的症状。

But here's the catch: Go on a hatching spree, and the host's immune system is going to take notice, and kick all the worms out.

无节制地进行孵化，会引起宿主免疫系统的注意，然后将所有清除出去。

I'm also going to send enough home for the whole flock because this is a good chance that if Ralph and Penny have coccidia and whipworms.

我还会给整个鸡群寄足够的钱，因为是一个很好的机会。如果拉尔夫和佩妮有球和。

Unlike animals, choanoflagellates can't trace their lineage back to the last common ancestor of all animals, this is according to many in-depth studies into the genetics of these organisms.

与动物不同，领不能追溯到所有动物的最后一个共同祖先，是根据对生物的遗传学进行的许多深入研究得出的结论。
