Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years. Yacold also

partners with nature portfolio to advance gut microbiome science through the global grants for

gut health, an investigator-led research program. To learn more about Yachtold, visit yacult.co.com.j, that's y-A-K-U-L-T-C-O-J-P.

Outsi, or as he's also known, the Iceman, was discovered frozen in the Alps in 1991 by two German tourists.

The 5,300-year-old body has been analyzed in various ways and been the subject of numerous scientific publications.

And now it's being looked at again because scientists realized that the contents of the

Iceman's stomach were still intact, which gave them the chance to look for evidence of the

common stomach bacteria, helicobacter pylori, or H. Pylori.

What they found tells us more about Ozi and more about how Ozi's ancestors came to Europe.

The study is in the journal science.

The researchers were able to extract genes from H. Pylori in the stomach to produce the oldest

known genome sequence of a pathogen. The iceman seems to have been infected with a virulent strain,

so in his last days on Earth, Outsi probably had one bad bellyache.

The strain had already reacted with the Isman immune system.

This we could show.

So we showed the presence of marker proteins, which we see today in patients infected with helicobacter.
