Caption: Stomach ulcer bacteria origins. Artwork of a human stomach and a magnified view of the Helicobacter pylori bacterium (green) that causes stomach ulcers. The East African countries on the map on the stomach show the origins of both humans and H. pylori from Africa, indicating that humans acquired this bacterium early on in their evolutionary history. The other labels indicate the location of the oesophagus, pyloric sphincter, and duodenum (first part of the small intestine).
