Hemozoin is released into blood during the infection of Plasmodium vivax every___.a)12 hrsb)72 hrsc)48 hrsd)24 hrsCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

No idea

Answer

Explanation:Hemozoin (Hz) is released into the blood stream after rupture of infected red blood cells (iRBCs) at the end of each parasite replication cycle. This free Hz is ingested by circulating and resident phagocytes. The presence of Hz in tissues after clearance of infection has been previously reported. Still, little is known about the kinetics of Hz in vivo, during and after Plasmodium infection. It is particularly important to understand Hz kinetics after malaria infections as it has been reported that Hz is associated with impairment of immune functions, including possible consequences for coinfections. Indeed, if Hz remains biologically active for prolonged periods of time inside immunocompetent cells, the potential consequences of such accumulation and presence to the immune system should be clarified.

Ans:72 hrs

Answer

Answer

B

Answer

As the haemozoin is responsible for the chill and the high fever for reccuring its every 3 to 4 days it realese which means 72 hours

Answer

Hemozoin is released into blood during the infection of plasmodium vivax every 72hours during the plasmodium cycle.

Answer

I think 72 hrs

Answer

24

Answer

72 hours is the answer because , at the beginning when the female anopheles mosquito bites a person, the infectious form of plasmodium that is sporozoites will enter the liver cells where they multiply themselves and then it will reach the RBCs where they again multiply and will result in the rupture of RBC.

THIS RUPTURED RBC IS KNOWN AS HAEMOZOIN

As this is not a quick life cycle or a process , it consumes a time period of three days

Answer

Every 3-4day means 72 hrs right..

Answer

Life cycle of plasmodium vivax in man when attaining the amoeboid ring stage,signant stage all this steps takes nearly 3 days so,the heamozoin release in the blood after 3 days (or) 72 hours of infection of plasmodium

Answer

The correct answer is 72 hours , because within this particular time period the sporozoites completes a cycle.
i.e., the parasites which have already reached the liver through blood, reproduces asexually in liver cells. Bursts out and released into the blood. Similarly parasites reproduces asexually in red blood cells and causes cycles of fever.

Answer

The reason is wait for mosquito

Answer

C is the right answer

Answer

Option C is correct answer.

Answer

Life cycle of Plasmodium vivax:

Plasmodium vivax is a protozoan parasite that causes malaria in humans. In the life cycle of Plasmodium vivax, the parasite goes through various stages in both the human host and the mosquito vector.

Release of Hemozoin:

Hemozoin is a byproduct of the digestion of hemoglobin by the malaria parasite. During the blood stage of the infection with Plasmodium vivax, the parasite digests hemoglobin in the red blood cells. As a result of this process, hemozoin crystals are formed.

Release time of Hemozoin:

In the case of Plasmodium vivax, hemozoin is released into the blood every 72 hours. This release corresponds to the periodicity of the fever spikes that occur in patients infected with Plasmodium vivax malaria. The 72-hour cycle is known as the tertian cycle.

Significance of Hemozoin release:

The release of hemozoin into the blood triggers the immune response in the host, leading to symptoms such as fever, chills, and anemia. Understanding the periodic release of hemozoin is crucial for the diagnosis and treatment of malaria caused by Plasmodium vivax.

Therefore, hemozoin is released into the blood every 72 hours during the infection of Plasmodium vivax, playing a key role in the pathogenesis of the disease.
