Helicobacter pylori, a bacterium that causes stomach ulcers, can grow in medium with a pH above 5. It can survive but not grow in pH 2 medium as long as the medium contains Urea. You inoculate a pH 2 broth with 1,000,000 H. pylori and for 8 hours the organism did not grow. The next morning however, the medium has become quite turbid, suggesting that the organism has grown. Explain how this could happen. What phylum and class does this organism belong?
