Effects of culture age (hence urease distribution) on survival of H. pylori 84-183 in saline (pH 7.2) and in acid (pH 2.0) containing 5 mM urea. Solid bars represent survival of 24-h fresh sub bacteria (which contain cytoplasmic urease almost exclusively), while open bars represent survival of 72-h fresh sub bacteria (which possess both cytoplasmic and/or surface-associated or extracellular urease).
