Ulcers Discovered in Mummies
Two Mexican mummies had ulcers when they were alive.

Remnants of the bacterium Helicobacter pylori were discovered in gastric tissue from the mummies, human remains believed to predate Columbus' discovery of the New World.

"It is only through the use of the stomach tissue of these incredible mummies that we were able to make this discovery," said researcher Yolanda Lòpez-Vidal. "Infection is established when the micro-organism infiltrates the stomach lining and induces a local inflammatory response. This is unlike colonization, which does not cause such a response and does not occur in the stomach."

It doesn't appear as if they found actual lesions, but the bacteria was present within the stomach lining which they say indicates an active infection.
