Targeting Ulcer Causing H. pylori Bacteria


Acids, Buffers, Transition Metals, Nickel

Featured Scientist

Sarah studies a protein from a pathogenic bacterium that is found in the stomach and is known to cause ulcers. She explains how the bacterium survives in the low pH environment of the stomach by using a nickel-dependent protein to buffer the acidity of its environment. Sarah envisions that taking advantage of this nickel requirement could lead to a new treatment for ulcers.
