Quiz Over Blood Parasites - Quiz

A plant or an organism that lives or on another and takes the nourishments from it is called a parasite. A parasite that can be blood borne is found in the blood stream of an infected person and can be transmitted to another individual exposure for example blood transfusion. This quiz over blood parasites will help you understand more.


Questions and Answers
  • 1. 

    Name this parasite form

    • A.

      Falciparum Gametocyte

    • B.

      Falciparum Schizont

    • C.

      Falciparum Trophozoite

    • D.

      Falciparum Oocyte

    Correct Answer
    A. Falciparum Gametocyte
    Explanation
    Falciparum Gametocyte is the correct answer because it is a stage in the life cycle of the Plasmodium falciparum parasite, which causes malaria. Gametocytes are the sexual stage of the parasite and are responsible for transmission to mosquitoes, which then spread the infection to other individuals. The other options (Falciparum Schizont, Falciparum Trophozoite, and Falciparum Oocyte) represent different stages in the asexual replication cycle of the parasite within human red blood cells.

    Correct Answer
    B. Plasmodium Vivax Ring Form
    Explanation
    The correct answer is Plasmodium Vivax Ring Form. Plasmodium vivax is a species of parasite that causes malaria in humans. It has a complex life cycle that involves both asexual reproduction in the human host and sexual reproduction in the mosquito vector. During the asexual stage, the parasite takes the form of ring-shaped structures within the red blood cells. These ring forms are characteristic of Plasmodium vivax infection and can be observed under a microscope.

      Plasmodium Falciparum Ring Form

    Correct Answer
    C. Plasmodium Falciparum Ring Form
    Explanation
    The correct answer is Plasmodium Falciparum Ring Form. Plasmodium falciparum is a parasite that causes the most severe form of malaria. In its ring form, the parasite infects red blood cells and replicates inside them. This stage of the parasite's life cycle is characterized by the formation of small rings within the red blood cells. Identifying the ring form is important for diagnosing and treating malaria, as different species of Plasmodium may require different treatment approaches.

    • D.

      Plasmodium Vivax Gametocyte

    Correct Answer
    A. Plasmodium Vivax Schizont
    Explanation
    The correct answer is Plasmodium Vivax Schizont. Plasmodium Vivax is a parasite that causes malaria in humans. Schizont is a stage in the life cycle of the parasite where it undergoes multiple nuclear divisions and produces merozoites. This stage is responsible for the destruction of red blood cells and the release of merozoites, which go on to infect more red blood cells.

    • A.

      Plasmodium Vivax Gametocyte

    • B.

      Plasmodium Vivax Oocyte

    • C.

      Plasmodium Vivax Schizont

    • D.

      Plasmodium Vivax Trophozoite

    Correct Answer
    D. Plasmodium Vivax Trophozoite
    Explanation
    The correct answer is Plasmodium Vivax Trophozoite. Plasmodium Vivax is a species of parasite that causes malaria in humans. The trophozoite stage is one of the developmental stages of the parasite within the human host. During this stage, the parasite feeds on red blood cells and multiplies. The trophozoite stage is characterized by the presence of a ring-like structure within the infected red blood cell. Therefore, Plasmodium Vivax Trophozoite refers to the specific form of the parasite during this stage of its life cycle.

      Schaefer's Dots

    • D.

      Schuffner's Dots

    Correct Answer
    D. Schuffner's Dots
    Explanation
    Schuffner's Dots are the inclusions found in red blood cells that are infected by parasites. These dots are commonly seen in infections caused by the malaria parasite, specifically the Plasmodium vivax and Plasmodium ovale species. They appear as small, dark-staining dots within the red blood cells when viewed under a microscope. These dots are an important diagnostic feature used to identify and differentiate between different species of malaria parasites.

    The inclusions in the parasite infected red cell appear only with:

    • A.

      Plasmodium Falciparum

    • B.

      Plasmodium Vivax

    • C.

      Plasmodium Malariae

    • D.

      Option 4

    Correct Answer
    B. Plasmodium Vivax
    Explanation
    The inclusions in the parasite infected red cell appear only with Plasmodium Vivax. This means that when red blood cells are infected with Plasmodium Vivax, there are specific inclusions that can be observed under a microscope. This is not the case with Plasmodium Falciparum or Plasmodium Malariae, as they do not produce the same type of inclusions in the infected red cells. Option 4 is not a valid option as it is not specified in the question.

    What is the vector for Leishmania?

    • A.

      Sand Fly

    • B.

      Tsetse Fly

    • C.

      Kissing Bug

    • D.

      Anopheles mosquito

    Correct Answer
    A. Sand Fly
    Explanation
    The correct answer is Sand Fly. Leishmania is a parasitic protozoan that causes leishmaniasis, a disease transmitted to humans through the bite of infected sand flies. Sand flies are small, blood-sucking insects found in tropical and subtropical regions. They are the primary vector for the transmission of Leishmania parasites to humans and animals. The parasites develop and multiply in the gut of the sand fly, and when the sand fly bites a human, it injects the parasites into the bloodstream, leading to infection. Therefore, the sand fly is the vector responsible for the transmission of Leishmania.

    • B.

      Sand Fly

    • C.

      Kissing Bug

    • D.

      Tsetse Fly

    Correct Answer
    A. Anopheles mosquito
    Explanation
    The vector for Plasmodium, the parasite that causes malaria, is the Anopheles mosquito. This mosquito species is responsible for transmitting the parasite to humans through its bite. When an infected mosquito bites a person, it injects the Plasmodium parasites into their bloodstream, leading to the development of malaria. Other options like the Sand Fly, Kissing Bug, and Tsetse Fly are vectors for different diseases, but not for Plasmodium.

    Only the female Anopheles mosquito can transmit Plasmodium

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because only the female Anopheles mosquito has the ability to transmit the Plasmodium parasite, which is responsible for causing malaria. Male mosquitoes do not have the necessary mouthparts to bite and feed on blood, which is required for the transmission of the parasite. Therefore, it is only the female mosquitoes that can transmit Plasmodium when they bite an infected individual and subsequently bite a healthy person, allowing the parasite to enter their bloodstream.

    What is the vector for T. Cruzi?

    • A.

      Sand Fly

    • B.

      Tsetse Fly

    • C.

      Kissing Bug

    • D.

      Anopheles mosquito

    Correct Answer
    C. Kissing Bug
    Explanation
    The vector for T. Cruzi is the Kissing Bug. The Kissing Bug is known to transmit the parasite T. Cruzi, which causes Chagas disease. This disease is primarily found in the Americas, and the Kissing Bug is commonly found in rural areas of these regions. It feeds on the blood of humans and animals, transmitting the parasite through its feces, which can enter the body through scratching the bite site or mucous membranes. Therefore, the Kissing Bug is the correct vector for T. Cruzi.

    • C.

      Sand Fly

    • D.

      Anopheles mosquito

    Correct Answer
    B. Tsetse Fly
    Explanation
    The correct answer is Tsetse Fly. Tsetse flies are known to be the vector for T. Brucei, which is the parasite that causes African trypanosomiasis, also known as sleeping sickness. Tsetse flies are found in sub-Saharan Africa and are responsible for transmitting the parasite to humans and animals through their bite. This makes them a significant carrier of the disease in the region.

    Which parasite causes Chagas?

    • A.

      Leishmania

    • B.

      T. Brucei

    • C.

      T. Cruzi

    • D.

      Plasmodium

    Correct Answer
    C. T. Cruzi
    Explanation
    T. Cruzi is the correct answer because it is the parasite that causes Chagas disease. Chagas disease, also known as American trypanosomiasis, is caused by the protozoan parasite Trypanosoma cruzi. It is primarily transmitted to humans through the bite of infected triatomine bugs, commonly known as "kissing bugs." The parasite can also be transmitted through blood transfusion, organ transplantation, consumption of contaminated food or drink, and from mother to baby during pregnancy. Chagas disease can lead to serious health complications, including heart and digestive problems.

    • D.

      T. Cruzi

    Correct Answer
    C. T. Brucei
    Explanation
    The correct answer is T. Brucei. T. Brucei is the parasite that causes African Sleeping Sickness, also known as African trypanosomiasis. This disease is transmitted to humans through the bite of infected tsetse flies. The parasite infects the central nervous system, causing symptoms such as fever, fatigue, headaches, and eventually leading to sleep disturbances, neurological problems, and even death if left untreated. Leishmania causes leishmaniasis, Plasmodium causes malaria, and T. Cruzi causes Chagas disease, none of which are associated with African Sleeping Sickness.

      Plasmodium

    • C.

      T. Brucei

    • D.

      T. Cruzi

    Correct Answer
    B. Plasmodium
    Explanation
    Plasmodium is the correct answer because it is the parasite that causes Malaria. Malaria is a mosquito-borne infectious disease that affects humans and other animals. Plasmodium is a genus of parasitic protozoans that are transmitted through the bite of infected female Anopheles mosquitoes. Once inside the human body, the Plasmodium parasite multiplies in the liver and then infects red blood cells, causing symptoms such as fever, chills, and flu-like illness. Therefore, Plasmodium is the causative agent of Malaria.

    What is the current best form of prevention for Malaria world wide?

    • A.

      Spraying insecticide

    • B.

      Bed nets

    • C.

      Vaccines

    Correct Answer
    B. Bed nets
    Explanation
    Bed nets are considered the current best form of prevention for Malaria worldwide. Bed nets are treated with insecticides that repel or kill mosquitoes, which are the main carriers of the Malaria parasite. When properly used, bed nets create a physical barrier that prevents mosquitoes from biting individuals while they sleep, reducing the risk of Malaria transmission. This cost-effective intervention has been proven to significantly reduce Malaria cases and is particularly effective in areas with high mosquito populations and limited access to healthcare services. Vaccines and insecticide spraying are also important prevention methods, but bed nets have shown to be the most effective and widely accessible solution.

    Plasmodium Falciparum does not usually have visable:

    • A.

      Schizont

    • B.

      Trophozoite

    • C.

      All of the above

    • D.

      None of the above

    Correct Answer
    C. All of the above
    Explanation
    The correct answer is "All of the above." Plasmodium falciparum, which causes the most severe form of malaria, does not usually have visible schizonts or trophozoites. Schizonts are the stage of the parasite where it reproduces asexually, and trophozoites are the stage where it feeds on red blood cells. However, it is important to note that while they may not be visible, these stages are still present in the life cycle of the parasite.
