Thiovulum (thigh-owe-vul-um) is a colourless sulphur bacteria, with deposits of sulphur granules around a central vacuole. Differential interference contrast.

Dozens of the curved bacteria fill the lumen of a gastric foveola. Hematoxylin & eosin stain, 1000X.

The organisms, scattered on and above the luminal surface, stain more boldly with the Giemsa technique. 1000X.

Description: A team of researchers from Boston University, Harvard Medical School and Massachusetts Institute of Technology have shown that the bacterium that causes human stomach ulcers uses a clever biochemical strategy to alter the physical properties of its environment, allowing it to move and survive and further colonize its host.Contact with stomach acid keeps the mucin lining the epithelial cell layer in a spongy gel-like state. This consistency is impermeable to the bacterium Heliobacter pylori. However, the bacterium releases urease which neutralizes the stomach acid. This causes the mucin to liquefy, and the bacterium can swim right through it. Read more about this research.
