Malignant tertain malaria is caused by Plasmodium :
1. Vivax
2. ovale
3. malariae
4. falciparum
Consider the given stages in the life cycle of Plasmodium and choose the correctly matched pair :
1. A : Merozites infect human when mosquito bites
2. B : Parasite reproduced sexually in liver cells
3. C : Symptoms of malaria
4. D : Fertilization in hemocoel of the mosquito
Consider the following statements:
I. | Plasmodium falciparum causes malignant tertian malaria |
II. | Release of hemosiderin from burst RBCs is responsible for paroxysms of malarial attacks |
III. | Sporozoites are the infectious forms of Plasmodium |
Which of the above statements are true?
1. I and II only
2. I and III only
3. II and III only
4. I, II, and III
Motile zygote of Plasmodium occurs in
1. gut of female Anopheles
2. salivary glands of Anopheles
3. human RBCs
4. human liver
Where will you look for the sporozoites of the malarial parasite?
1. Red blood corpuscles of humans suffering from malaria
2. Spleen of infected humans
3. Salivary glands of freshly moulted female Anopheles mosquito
4. Saliva of infected female Anopheles mosquito
The so-called tertain periodicity of Plasmodium vivax refers to the
1. pre-erythrocytic phase
2. post erythrocytic phase
3. erythrocytic phase
4. sexual phase.
Sexual stage (gametocytes) of plasmodium occurs in
1. Salivary glands of mosquito
2. Human RBC
3. Intestine of mosquito
4. Human liver
Which of the following factor is incorrect for the low levels of immune response during Plasmodium infection?
1. | Different types of antigens are expressed at varying stages of Plasmodium life cycle |
2. | The stages during its life cycle are mostly intracellular |
3. | The sporozoites of Plasmodium are rapidly cleared from blood circulation |
4. | Plasmodium infection primarily destroys the macrophages and dendritic cells present in blood |
Malaria can be understood well by which statement?
1. Plasmodium, a macroscopic protozoan is responsible for Malaria
2. The bite of a female Anopheles mosquito will always lead to malaria
3. Chills and high fever recurring every 6 to 7 days are because of hemozoin
4. Sporozoites are formed in mosquito's body
Reproduction of parasite(plasmodium) in red blood cells is
1. Asexual
2. Sexual
3. Both
4. Do not reproduce there
