Protein Necessary for Bacteria to Produce Ulcers

When it comes to the ability of the bacterium Helicobacter pylori to effectively colonize the stomach and eventually cause ulcers it all comes down to a single protein.

H. pylori strains infect half of all humans worldwide and contribute to the development of peptic ulcers and gastric cancer. They cannot survive the harsh acidic environment inside stomach cavity and must therefore use their flagella to actively swim to and colonize the protective mucus and lining of the stomach. Researchers have discovered a novel protein, called ChePep, that the bacterium requires to swim properly.

Although H. pylori lacking ChePep have normal looking flagella and are mobile, when they swim they have a slight defect that can cause them to go backwards. If they cannot swim away from the acid and into the protective lining of the stomach, they die.
