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.

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.
