About This Quiz

How much do you understand parasitology? Here are some interesting parasitology quiz questions and answers for you to test your knowledge as well as learn more. Medical parasitology traditionally contains the study of three major groups of animals. These groups are parasitic protozoa, parasitic helminths (worms), and then arthropods that directly spread disease or act as vectors of various pathogens. All the best to you with this test, and improve your learning!

  • 2. 

    Entamoeba hartmanni is pathogenic.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Entamoeba hartmanni is a non-pathogenic species of amoeba that resides in the human intestines. It does not cause any disease or harm to the host. Therefore, the statement that Entamoeba hartmanni is pathogenic is false.

    Rate this question:

  • 3. 

    Trophozoites of Entamoeba Hartmanni ingest RBCs.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Trophozoites of Entamoeba Hartmanni do not ingest RBCs. Instead, they primarily feed on bacteria and other microorganisms present in the intestine.

    Rate this question:

  • 4. 

    This is the first parasitic ameba of humans to be described. It is found in the soft tartar between the teeth; also recovered from the tonsillar crypts.  Its Trophozites measure 5 -15 um. What entamoeba am I talking about?

    • Entamoeba Histolytica

    • Entamoeba Hartmanni

    • Entamoeba Gingivalis

    • Entamoeba Coli

    • Entaomoeba Relipus

    Correct Answer
    A. Entamoeba Gingivalis
    Explanation
    Entamoeba gingivalis is the correct answer because it is the only option that matches the description given in the question. The question states that this parasite is found in the soft tartar between the teeth and recovered from the tonsillar crypts, and its trophozoites measure 5-15 um. Entamoeba gingivalis is known to inhabit the oral cavity and is commonly found in dental plaque and periodontal pockets. Its trophozoites are indeed in the size range mentioned. Therefore, based on the information provided, Entamoeba gingivalis is the most suitable answer.

    Rate this question:

  • 5. 

    The cysts of Entamoeba Histolytica contain ______ nuclei; more nuclei are seen as the cyst matures.

    • 1-7

    • 2-4

    • 3-6

    • 1-4

    • 1-3

    Correct Answer
    A. 1-4
    Explanation
    As the cyst of Entamoeba Histolytica matures, it contains more nuclei. The correct answer, 1-4, indicates that the cyst can have a range of 1 to 4 nuclei. This suggests that as the cyst develops further, it may contain more nuclei, but it will never exceed 4.

    Rate this question:

  • 6. 

    This is the only Entamoeba to have no cyst stage.

    • Entamoeba Gingivitis

    • Entamoeba Polecki

    • Entamoeba Histolytica

    • Entamoeba Coli

    • Entamoeba Hartmanni

    Correct Answer
    A. Entamoeba Gingivitis
  • 7. 

    E.coli is a pathogenic commensal organism.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    E.coli is a type of bacteria that is commonly found in the intestines of humans and animals. While some strains of E.coli can cause illness, not all strains are pathogenic. In fact, many strains of E.coli are harmless and considered commensal, meaning they coexist with their host without causing harm. Therefore, the statement that E.coli is a pathogenic commensal organism is false.

    Rate this question:

  • 8. 

    Trophozoites of Entamoeba Histolytica are  ____- ______ um in size.

    • 11-22

    • 10-20

    • 5-15

    • 7-14

    • 9-18

    Correct Answer
    A. 10-20
    Explanation
    Trophozoites of Entamoeba Histolytica are 10-20 um in size.

    Rate this question:

  • 9. 

    Entamoeba Histolytica cysts are also _____ - ______ um in size and are round.

    • 10-20

    • 12-24

    • 11-22

    • 5-10

    • 2-5

    Correct Answer
    A. 10-20
    Explanation
    Entamoeba Histolytica cysts are also 10-20 um in size and are round.

    Rate this question:

  • 10. 

    The cysts of Entamoeba Hartmanni differ from E. histolytica because frequently the cysts contain only ____  or _____ nuclei even though the mature cyst contain 4 nuclei.

    • 0 or 1

    • 2 or 3

    • 1 or 2

    • 1 or 4

    Correct Answer
    A. 1 or 2
    Explanation
    The cysts of Entamoeba Hartmanni differ from E. histolytica because frequently the cysts contain only 1 or 2 nuclei even though the mature cyst contains 4 nuclei.

    Rate this question:

  • 11. 

    Due to the small size of Endolimax Nana, it is usually identified on a temporary stain.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Endolimax Nana is a type of parasite that infects the human intestines. It is not identified on a temporary stain due to its small size. Instead, it is identified through a process called direct wet mount microscopy, where a sample is observed under a microscope without any staining. Therefore, the given statement is false.

    Rate this question:

  • 12. 

    This is the only Entamoeba to ingest WBCs. What is it?

    • Entamoeba Coli

    • Entamoeba Gingivalis

    • Entamoeba Polecki

    • Entamoeba Hartmanni

    • Entamoeba Histolytica

    Correct Answer
    A. Entamoeba Gingivalis
    Explanation
    Entamoeba gingivalis is the correct answer because it is the only species of Entamoeba that is known to ingest white blood cells (WBCs). This protozoan parasite is commonly found in the oral cavity and can cause periodontal disease. It is able to phagocytose and feed on WBCs, which contributes to its pathogenicity in the oral environment. Other species of Entamoeba, such as Entamoeba coli, Entamoeba polecki, Entamoeba hartmanni, and Entamoeba histolytica, do not have this ability.

    Rate this question:

  • 13. 

    This organism is identified by seeing one nucleus in mature cysts; rarely 2 or 4 also seen this is likely

    • Entamoeba Coli

    • Entamoeba Polecki

    • Entamoeba Hartmanni

    • Entamoeba Histolytica

    Correct Answer
    A. Entamoeba Polecki
    Explanation
    This organism is identified by seeing one nucleus in mature cysts; rarely 2 or 4 also seen. The correct answer is Entamoeba Polecki.

    Rate this question:

  • 14. 

    The cysts size for Entamoeba Hartmanni range from _____ to _____ um.

    • 5-10

    • 4-8

    • 3-6

    • 4-10

    • 4-12

    Correct Answer
    A. 5-10
    Explanation
    The correct answer is 5-10. This range indicates the size of cysts for the parasite Entamoeba Hartmanni. The size of the cysts can vary within this range, with the smallest being 5 micrometers and the largest being 10 micrometers.

    Rate this question:

  • 15. 

    The  trophozoites from Entamoeba Hartmani range in size from _____ to ___ um.

    • 3-10

    • 2-12

    • 4-12

    • 5-10

    • 6-10

    Correct Answer
    A. 4-12
    Explanation
    The correct answer is 4-12. This is because trophozoites from Entamoeba Hartmani can vary in size and can be as small as 4 micrometers or as large as 12 micrometers.
