Sample item

What protozoan can cause dysentery with flask-shaped ulcers?

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

The answer and the reasoning

B. Entamoeba histolytica

The central Parasitology concept identifies Entamoeba histolytica as the best answer because it directly explains the mechanism, indication, adverse effect, or organism feature described.

Option by option

  • A. Giardia lamblia

    Giardia lamblia does not fit the stated parasitology relationship.

  • B. Entamoeba histolytica (correct)

    Correct. Entamoeba histolytica matches the decisive point in this scenario.

  • C. Toxoplasma gondii

    Toxoplasma gondii is unsupported by the mechanism or clinical clue in the stem.

  • D. Plasmodium falciparum

    Plasmodium falciparum has another context but is not the most appropriate answer here.
