Helicobacter pylori. Coloured transmission electron micrograph (TEM) of a Helicobacter pylori bacterium (formerly known as Campylobacter pyloridis). This Gram-negative bacillus bacterium is curved (as here) or spiral in shape, with flagellae for motility. Here, many hair-like flagellae are visible. Colonies of occur on the stomach mucous membrane in people suffering gastritis, and this bacteria has been linked to stomach ulcer formation. may also be a co-factor for gastric cancer; its presence increases the risk of stomach tumours.
