Ancient ulcers

Scientist have found HPylori in the stomach of Otzi the iceman...

The scientists found a potentially virulent strain of bacteria, to which Ötzi's immune system had already reacted. "We showed the presence of marker proteins which we see today in patients infected with Helicobacter," said the microbiologist. A tenth of infected people develop further clinical complications, such as gastritis or stomach ulcers, mostly in old age. "Whether Ötzi suffered from stomach problems cannot be said with any degree of certainty," says Zink, "because his stomach tissue has not survived and it is in this tissue that such diseases can be discerned first. Nonetheless, the preconditions for such a disease did in fact exist in Ötzi."
