You Examine a Patient Who Is Complaining of Belching (Burping)

question 76

Multiple Choice

You examine a patient who is complaining of belching (burping) , bloating, and some vomiting. She also has some abdominal discomfort which she describes as a dull, burning pain that is worse when she is hungry and is often relieved when she takes antacids. You suspect that she may have Helicobacter pylori gastritis, and send her for a urea breath test. The breath test is positive; based on this, you get the patient's stool tested for blood, and you send her for an endoscopy, during which a biopsy is taken. Your diagnosis is confirmed by the results of these tests and that she does indeed have H. pylori.
-Your patient asks you how a bacterium can survive in her stomach, which she knows is very acidic. You explain that

• A) H. pylori produces urease that converts urea into carbon dioxide and ammonia; the ammonia neutralizes the pH of the stomach, allowing the bacteria to survive.
• B) H. pylori has the ability to form endospores in hostile environmental conditions. It does this in the acidic stomach, only germinating once they reach the small intestine.
• C) H. pylori is an acidophile, and as such prefers acidic pH levels of 1-3; gastric juices contain hydrochloric acid which has a very low pH.
• D) H. pylori is encased in the very thick polysaccharide capsule that protects it from the degradative effects of the HCl found in the stomach.
• E) H. pylori forms a biofilm with the other normal microbiota of the stomach. The structure of the biofilm covers and protects the bacteria within it.
