Ancient Teeth Unlock Plague Secrets
古代牙齿解开瘟疫的秘密

Nearly 4,000 years ago, a woman and a man were buried together just east of the Volga River in modern-day Russia, with a secret locked away in the pulp of their teeth.
大约4000年前,一名妇女和一名男子被葬在现在俄罗斯的伏尔加河以东,一个秘密被锁藏在他们的牙髓里。

The bodies were uncovered just a few years ago, the teeth pulled and sent westward to the Max Planck Institute in Germany, where Maria Spyrou was working on a Ph.D. in paleogenetics. When she subjected the pulp to a bevy of genetic tests, she found something surprising: an ancestor of the bacteria responsible for the Black Death.
这些尸体在几年前就被发现了,牙齿被拔掉并送到了德国的马克斯-普朗克研究所,在那里Maria Spyrou正致力于古遗传学博士学位。当她将牙髓移植到一系列基因测试中时,她发现了一些令人惊讶的东西:一种导致黑死病的细菌的祖先。

She published that finding in Nature Communications, providing evidence that the bacteria has origins at least 800 years earlier than scientists had previously thought.
她在《自然通讯》发布了这一发现,为细菌的起源提供了比科学家先前认为的要早至少800年的证据。
