Ötzi the Iceman still harbors living microbes more than 5,300 years on

Researchers uncover traces of ancient microbes inside a mummy; these were unexpected “signs of life” that may have persisted for more than 5,300 years.

The study, recently published in the journal Microbiome, focuses on the mummy of Ötzi the Iceman, found by a tourist in a glacier in the Alps in 1991, SWNS news agency reported.

Ötzi’s remains were found in B.C., before Stonehenge and the Egyptian pyramids were built. It dates back to 3300 BC. He was between 25 and 35 years old when he died and was roughly 5 feet 2 inches tall.

Researchers initially believed he succumbed to exposure or exhaustion while crossing the Alps, but later examination found that an arrowhead had lodged in his left shoulder; This indicates that he probably died from blood loss.

Experts at Eurac Research have found that Ötzi’s remains still contain a complex community of ancient and modern microorganisms, offering a rare insight into the microbial history of early humans.

Researchers examining the mummy at the South Tyrol Archaeological Museum in Bolzano, Italy, found genetic traces of cold-adapted yeasts and bacteria from Ötzi’s ancient gut microbiome.

Additionally, using tissue samples, swab samples, and genetic analysis, distinctions were made between microorganisms that were present during Ötzi’s lifetime and microorganisms that colonized his body after his death.

The team analyzed the ice on the surface of Ötzi’s body, as well as the meltwater inside the mummy. The researchers also took advantage of intestinal tissue and stomach content data from previous studies.

A surprising discovery was the presence of cold-adapted yeast species, possibly resulting from the glacial environment, that survive to this day in Ötzi’s body.

“Ötzi offers a rare glimpse into humanity’s microbial past.”

Ötzi’s microbiome was also unique in that it contained gut bacteria not typically found in the intestines of modern humans, the researchers said.

“Ötzi therefore offers a rare glimpse into humanity’s microbial past,” Eurac Research said in a statement. he said.

Experts said that since Ötzi’s body was found in the South Tyrol Museum, some microbes may still exist dormant even 5,000 years after his death.

Elisabeth Vallazza, director of the South Tyrol Archaeological Museum, described the mummy’s state of preservation as “fairly stable today.”

“Close microbiological monitoring ensures that the mummy does not suffer any damage,” Vallazza said in a statement.

“But more research and full conservation efforts are definitely needed to preserve it for more generations.”

Despite the findings, there is still mystery about how microorganisms survived and interacted in Ötzi’s frozen remains.

As SWNS reported, conservation expert and co-author Marco Samadelli said the conditions “are not yet fully understood.”

“This study expands our knowledge in this area.”

Frank Maixner, Director of the Eurac Research Institute for Mummy Studies, said the discovery points to the continuous presence of certain microorganisms throughout the mummy’s long history.

He added that Ötzi was “not a static remnant but a dynamic biological system.”
