A team of scientists are currently examining specimens of stomach bacteria from Ötzi the Iceman, who lived about 5,300 years ago, at Stockholm's Karolinska Institute (KI).
Ötzi was discovered by two Germans tourists in September 1991 in the Ötztal Alps, near Hauslabjoch in Italy close to the Austria border.
His body is usually kept frozen, but he has been thawed recently to allow experts to examine him, among them Swedish infectious disease control professor Lars Engstrand at KI.
Engstrand hopes that the samples will reveal whether Ötzi had gastric ulcer and resistant bacteria.
"We are performing DNA extraction to map the gastric and intestinal microflora from 5,000 years ago and to try out to find if he had any signs of ulcer-causing bacteria. We will probably be finished in a couple of months, that's my gut feeling," Engstrand told The Local on Wednesday.
Engstrand and his team received faecal samples, as well as a 1 square centimetre section of Ötzi's stomach, on November 8th and will disclose their findings through scientific journals.
Engstrand is working with other scientists in Germany and Bordeaux to find any possible resistant genes that Ötzi may have possessed before the antibiotic era.
"We are quite convinced that we will find something. They have been found in soil bacteria. It will be interesting to see how these genes looked like then compared with today," explained Engstrand.
"This is a scientific study for public health, antibiotic resistance and virulence as these genes may have evolved over the years," he added.
Engstrand has never worked with such dated material, but pointed out that the material was long dead when they received it and as such, there are no viable organisms, so they are only working with DNA.
"This part of the body has not been exposed to other contaminating bacteria. He has been frozen for so many years, the DNA quality is crucial to our success," said Engstrand.
