Weekly Quiz Competition
  • Question 1
    1 / -0
    Study the following traits of a disorder and identify the disorder. 
    (a) Inflammation of the mucous membrane of the nasal passage 
    (b) Watery secretions by mucous glands 
    (c) Continuous sneezing 
    (d) Eye watering 
    (e) Rise in body temperature
    Solution
    Allergic rhinitis, also known as hay fever, is a type of inflammation in the nose which occurs when the immune system hypersensitizes to allergens in the air. Signs and symptoms include a runny or stuffy nose, sneezing, red, itchy, and watery eyes, and swelling around the eyes. inflammation of mucous membrane of the nose, fever.
    So, the correct answer is 'Rhinitis'.
  • Question 2
    1 / -0
    AIDS does not spreads through 
    Solution
    • AIDS (Acquired Immunodeficiency Syndrome) is caused by the HIV virus.
    • AIDS does not spread from person to person through direct contact (touching a person who has the infection), indirect contact (touching a contaminated object), or droplet contact (inhaling droplets made when a person who has the infection coughs, sneezes, or talks).
    • Hence, AIDS does not spread through contact with the clothes of an AIDS patient.
    So, the correct answer is 'Contact with clothes of an AIDS patient'.
  • Question 3
    1 / -0
    Which of the following is not an autoimmune disease?
    Solution
    • An autoimmune disease is a condition in which your immune system mistakenly attacks your body. For example, Graves disease, Pernicious anemia and Rheumatoid arthritis.
    • Insomnia is a sleep disorder that is characterized by difficulty falling or staying asleep.
    • Symptoms include difficulty falling asleep, waking up during sleep and trouble going back to sleep, waking up too early in the morning and feeling tired upon waking.
    • Anxiety, stress, and depression are some of the most common causes of chronic insomnia.
    • Hence insomnia is not an autoimmune disease.
    • So, the correct answer is 'Insomnia'.
  • Question 4
    1 / -0
    Which stage of Wuchereria bancrofti is infective to man 
    Solution
    • Wuchereria bancrofti is a human parasitic roundworm that is the major cause of lymphatic filariasis. 
    • In the thoracic muscle of mosquito, microfilariae develop into first-stage larvae and subsequently into third-stage infective larvae.
    • The third-stage infective larvae enter the blood of human by the mosquito. They then migrate to the nearest lymph gland where they mature into the thread like adult worms. Hence, the Third stage larva of Wuchereria bancrofti is infective to man.
    So, the correct answer is 'Third stage larva'.
  • Question 5
    1 / -0
    Fourth moulting of Ascaris occurs in
    Solution
    Ascaris is a genus of parasitic nematode worms. The larvae undergo first moulting in the soil. Then the larvae undergo second and third moulting in the lungs. Then, fourth moulting occurs in host intestine. 2nd stage larva goes from soil to lungs. 4th stage larva goes from lungs to intestine. Sometimes the 2nd stage larva from the lungs travels to the CSF (cerebrospinal fluid) via the heart.
    So, the correct answer is 'Intestine'.
  • Question 6
    1 / -0
    Filarial parasitic worms is transmitted by
    Solution
    The three parasitic worms, Wuchereria bancrofti, Brugia malayi, B. timori,  infect the lymphatic system to cause lymphatic filariasis. These filarial worms are spread by a variety of mosquito vector species, particularly by the bite of infective female Culex mosquito. W. bancrofti is responsible for 90% of lymphatic filariasis. The mosquito vectors of W. bancrofti have a preference for human blood, humans are naturally infected with W. bancrofti.
    So, the correct answer is 'Mosquito'.
  • Question 7
    1 / -0
    Select  the statement about diseases and immunisation
    Solution
    B cells, also known as B lymphocytes are a type of white blood cell.  A BCR (B-cell receptor) binds an antigen. Then the antigen is taken up into the B cell through receptor-mediated endocytosis, degraded, and presented to T cells as peptide pieces in complex with MHC-II molecules on the cell membrane. If B and T- lymphocytes are damaged, the body will not be able to produce antibody against pathogen because antibodies are produced from B-lymphocyte.
    So, the correct answer is 'If due to some reason, B-and T-lymphocytes are damaged the body will not produce an antibody against a pathogen'.
  • Question 8
    1 / -0
    People at high risk of getting HIV infection are 
    Solution
    Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) is an immunodeficiency disease caused by infection with the human immunodeficiency virus (HIV). People who are at high risk of getting the infection are - 
    • The most frequent mode of transmission of HIV is through sexual contact with an infected person. The individual with multiple sexual partners is at increased risk of developing HIV.
    • Intravenous drug use plays a role in the spread of HIV by increasing the likelihood of high-risk sex with infected partners. The intoxicating effects of many drugs can alter judgment and lead people to engage in impulsive and unsafe behaviours.
    • AIDS also spread through blood transfusion of infected blood. The individuals who require repeated blood transfusions are at increased risk of developing HIV.
    So, the correct answer is 'All the above'.
  • Question 9
    1 / -0
    At which stage of HIV infection does the patient shows symptoms of AIDS
    Solution
    • AIDS (acquired immunodeficiency syndrome) is caused by the HIV virus
    • T-helper cells play an important role in adaptive immunity. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells.
    • HIV replicates rapidly in helper T-lymphocytes(CD 4) and damages a large number of them. They're responsible for keeping you healthy from common diseases and infections. As HIV gradually weakens your natural defences, signs and symptoms will occur.
    • So, the correct answer is 'HIV replicates rapidly in helper T-lymphocytes and damages a large number of them'.
  • Question 10
    1 / -0
    Which of the following is not a component of nonspecific defense?
    Solution
    The second line of defence involves non-specific cellular and molecular responses of the innate immune system because these defences do not differentiate between different types of the pathogen and respond the same way upon every infection. Mucous membrane, phagocytes and lysozyme are all involved in a non-specific defence mechanism, whereas, killer T-cells or cytotoxic T-cells provide the third line of defence.
    So, the correct answer is 'Killer T-cells'.
