Sample item

Which bacterial feature allows Helicobacter pylori to survive gastric acidity?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Urease production

H. pylori produces urease, generating ammonia that buffers local acid and facilitates colonization of the gastric mucus layer.

Option by option

  • A. Capsule only

    Capsule is not the key acid-survival mechanism.

  • B. Urease production (correct)

    Correct: urease creates a locally less acidic microenvironment.

  • C. Endospore formation

    H. pylori does not form spores.

  • D. Obligate intracellular growth

    It is not obligately intracellular.
