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

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.
-Helicobacter pylori, a curved, Gram-negative microaerophilic motile bacterium. Based on this, how do you describe the organism to your patient?

A) The organism causing your signs and symptoms is a virus that requires oxygen for survival, has a thin cell wall composed of a compound called peptin, and can move by means of tail-like structures called flagella.
B) The organism causing your signs and symptoms is a bacterium that requires atmospheric levels of oxygen for survival, has a thick cell wall composed of a compound called peptidoglycan, and can move by means of appendages called cilia.
C) The organism causing your signs and symptoms is a protozoan that requires low levels of oxygen for survival, has a thin cell wall composed of a compound called chitin, and moves around your stomach by means of structures called flagella.
D) The organism causing your signs and symptoms is a bacterium that requires low levels of oxygen for survival, has a thin cell wall composed of a compound called peptidoglycan, and can move by means of tail-like structures called flagella.
E) The organism causing your signs and symptoms is a bacterium that cannot grow in the presence of oxygen, has a thick cell wall composed of a compound called peptidoglycan, and can move by means of tail-like structures called flagella.
