    What is part of Parasitology?

    • A.

      Streptococcus

    • B.

      M. pneumonia

    • C.

      Helminths

    • D.

      Herpes

    • E.

      All of the above

    Correct Answer
    C. Helminths
    Explanation
    Parasitology is the study of parasites and their interactions with their hosts. Helminths, which include various types of worms, are a common type of parasite that infect humans and animals. They are often studied in the field of parasitology because of their complex life cycles and the diseases they can cause. Streptococcus, M. pneumonia, and Herpes, on the other hand, are not parasites but rather bacteria and viruses that can cause infections in humans. Therefore, the correct answer is helminths, as they are part of the field of parasitology.

      Mycoplasma

    • D.

      Protozoa

    • E.

      Rickettsia

    Correct Answer
    D. Protozoa
    Explanation
    Protozoa is not a prokaryotic microbe because prokaryotes are organisms that lack a nucleus and membrane-bound organelles, while protozoa are eukaryotes. Eukaryotes have a true nucleus and membrane-bound organelles. Bacteria, Chlamydia, Mycoplasma, and Rickettsia are all examples of prokaryotic microbes.

    • D.

      Helminths

    • E.

      None of the above

    Correct Answer
    C. Chlamydia
    Explanation
    Chlamydia is not a eukaryotic microbe. Eukaryotic microbes are organisms whose cells have a true nucleus and other membrane-bound organelles. Algae and fungi are examples of eukaryotic microbes. Chlamydia, on the other hand, is a bacteria that lacks a true nucleus and other membrane-bound organelles, making it a prokaryote. Helminths, which include parasitic worms, are also eukaryotic microbes. Therefore, the correct answer is Chlamydia.

    • E.

      Macrocystis

    Correct Answer
    B. Coxiella burnetti
    Explanation
    Coxiella burnetii is a Rickettsia because it is a gram-negative bacterium that causes Q fever in humans. Rickettsia is a genus of bacteria that are obligate intracellular parasites and are transmitted to humans through arthropod vectors. Coxiella burnetii is commonly found in livestock and can be transmitted to humans through inhalation of contaminated aerosols or ingestion of contaminated milk or meat. Q fever can cause flu-like symptoms and can lead to severe complications in some cases.

    Correct Answer
    B. Aspergillus
    Explanation
    Aspergillus is a type of fungi. Fungi are eukaryotic organisms that are heterotrophic and obtain nutrients by absorbing them from their surroundings. Aspergillus is a common mold that can be found in various environments such as soil, decaying organic matter, and indoor spaces. It is known for its ability to produce spores that can cause respiratory issues in humans. Amoeba, Ascaris, E. coli, and Rickettsia are not fungi but belong to other groups of organisms such as protists, roundworms, bacteria, and bacteria-like organisms respectively.

    Explanation
    Aflatoxin is produced by Aspergillus, a type of fungus. Aflatoxin is a toxic substance that can contaminate crops such as peanuts, corn, and tree nuts. It is a potent carcinogen and can cause liver damage in humans and animals. Aspergillus grows on crops under certain conditions of temperature and humidity, and if not properly stored or processed, the fungus can produce aflatoxin. Therefore, Aspergillus is the correct answer as it is the main producer of aflatoxin.

      Wuchereria bancraftii

    Correct Answer
    E. Wuchereria bancraftii
    Explanation
    Wuchereria bancrofti is a parasitic worm that causes elephantiasis. The presence of this worm in the lymphatic system leads to blockages and swelling in the limbs and genitals, resulting in the characteristic symptoms of elephantiasis. Aspergillus is a type of fungus, C. trichomatis and Trichomonas vaginalis are bacteria that cause sexually transmitted infections, and Rickettsia prowazekii is a bacteria that causes epidemic typhus. None of these organisms are known to cause elephantiasis.
