In the West, there have been successful phage trials for foot ulcers.

在西方，已经有成功噬试验治疗足溃疡。

A phage is a virus; not quite alive, not quite dead.

噬种病毒；然而它并不完全活，也不完全死。

There are more phages on earth than every other organism combined, including bacteria.

地球上所有有机加起来也没有噬数多，包括细。

Phages, viruses that attack bacteria but don't affect humans, are one promising new avenue to combat bacterial infections.

噬，种能攻击细但不感染人病毒，个很有前景对抗细感染新途径。

This happens when phages, rather than killing their hosts immediately, integrate their genomes into those of their prey.

当噬不立即杀死宿主，而将自己基因组整合到猎物基因组中时，就会发生这种情况。

That helps the phages, because their bacterial prey also accumulate in mucus, which is thus a rich hunting ground.

这有助于噬，因为细侵染过程也积聚在粘液中，这就为噬提供了寄生宿主。

Which might make you nervous since phages are responsible for the majority of deaths on earth but you're lucky.

可能世界上部分死亡都由噬导致，这事实会让你感到紧张，然而你很幸运。

But phages also have major flaws.

然而，噬有个最缺点。

Like any other virus, phages need a host to survive and reproduce.

像所有其他病毒样，噬需要宿主来生存繁殖。

Several clinical trials of phage therapy have already been successfully conducted in Poland, the nation of Georgia and Bangladesh.

波兰、格鲁吉亚和孟加拉国已经成功地进行了若干噬治疗临床试验。

The side touching the food is coated with phage E2, a virus engineered to stick only to Salmonella typhimurium bacteria.

触摸食物边涂有噬E2, 这种被研发成只会依附鼠伤寒沙门氏病毒。

Usually, a phage has chosen one specific bacteria and maybe some of its very close relatives.

通常情况下，个噬只寄生某种细以及些它们近亲。

Dr Chen reckons that phages could in this way end up stealing up to a quarter of their host's genome.

陈博士认为噬可以通过这种方式窃取四分之宿主基因组。

In phages, Dr Barr discovered, the various versions of Hoc stick to the varied branched sugar molecules characteristic of mucus.

Barr博士发现不同HOC蛋白与不同粘液特征性多糖分子支链相结合。

Typically, a phage will only infect a single bacterial species.

通常， 噬只会感染种细。

The way the phage hunts is with its feet.

噬捕食方式用脚。

Smith's method is known as “phage display.”

史密斯方法被称为“噬展示”。

Winter used Smith's phage display method to create new kinds of antibodies.

温特使用史密斯噬展示方法创造了新型抗。

Phages need a healthy population of bacteria  to survive.

噬需要健康细群落才能生存。

But for the  phage and bacteria this is great.

但对于噬和细来说, 这很棒。
