The Protist That Causes Malaria

The Protist That Causes Malaria: Mosquitoes, which are carriers of the parasite that causes malaria, are responsible for the disease’s transmission. They are more common in regions with higher average temperatures, such as Africa, Asia, and South, and Central America, and the UK does not have any of these. Mosquitoes are infected by sucking the blood of people who are already infected with protists. They transmit the parasite to other individuals after sucking blood from them. The mosquitoes themselves do not become ill; rather, they are referred to as “vectors” since they are responsible for spreading the disease.

Malaria is characterized by a high temperature accompanied by sweating and chills, as well as headaches, vomiting, and diarrhea. This illness claims the lives of up to half of the approximately 200 million individuals who are affected every year. Malaria cannot be prevented with immunization at this time. Only by protecting others from getting bitten can an infection be stopped in its tracks. People sleep with mosquito nets over their beds and use bug spray to protect themselves from getting bitten. Antimalarial medications, which treat the symptoms of malaria as well as help prevent infection, are also taken.

In certain regions of Southeast Asia, Central and South America, and Sub-Saharan Africa, malaria poses a significant threat to the public’s health. Malaria caused about 200 million infections and nearly 500,000 deaths in 2013, according to the World Health Organization.

Protists, which are single-celled eukaryotes, are the organisms responsible for malaria. There are between four and five different species of Plasmodium that are capable of causing malaria in humans. Each species is capable of causing a unique set of symptoms and consequences, and a competent technician will even be able to distinguish between the four species by using a microscope. On the other hand, the life cycles of each of the malaria parasites are virtually identical.

The female mosquito is where the life cycle of the malaria parasite begins. After biting a person for a blood meal, the female mosquito will then transmit the malaria parasite to the human host. The malaria parasite, after it has entered a human host, will initially make its way to the liver. In this location, it will begin to reproduce, so bolstering its troops in preparation for an assault on the red blood cells.

After the malaria parasites have completed their reproduction in the liver, they will then move on to infect the red blood cells. The parasites will reproduce several times within the red blood cells, and then they will burst out of the cells to continue the process of infection.

Malaria symptoms are the outcome of an infection stage that destroys red blood cells. Malaria is caused by the parasite Plasmodium. As a result of the tendency of the malaria parasites to multiply at the same time, the signs and symptoms of malaria frequently appear in waves in the patient. Some of the malaria parasites that are present in the blood will eventually mutate into a form that can be carried by a mosquito and transmitted to another human being.

What is the main cause of malaria?

Let’s have a look at some of the individual features of the malaria parasites now that we have a firm grasp on the life cycle of the parasites that cause malaria.

Carriers of the Chagas disease. vector. The Trypanosoma parasite that causes Chagas disease is transmitted by an insect that is frequently referred to as the “kissing bug.” It’s possible that even one bite from this insect might be fatal.

The finding that Chagas disease exists is unprecedented in the annals of medical research. This is due to the fact that just one researcher, a Brazilian physician by the name of Carlos Chagas, was responsible for recognizing and explaining the newly discovered infectious illness. Chagas carried out meticulous research in both the laboratory and the field in the early 1900s. He discovered the illness’s causative agent, as well as its vector, host, symptoms, and route of transmission. The disease is currently known in his honor.

Giardia are flagellate protozoa that cause giardiasis. Food or water that has been polluted by the excrement of infected individuals or animals is the means through which the parasites make their way into the body. The protozoa attach themselves to the lining of the small intestine of the host, and there they block the host from receiving all of the nutrients. They also have the potential to induce fever, diarrhea, and stomach discomfort. This idea is introduced with an image of a protozoan called Giardia.

Plasmodium protozoa cause malaria. A mosquito acts as a vector for the propagation of the parasites. The bite of a mosquito that is carrying a parasite allows it to enter the bloodstream of its host. The red blood cells of the host are infected by the parasites, which results in symptoms such as fever, discomfort in the joints, anemia, and weariness.

The risk of contracting malaria is highest in tropical and subtropical regions everywhere in the world (see Figure below). Malaria is, in point of fact, one of the infectious diseases that are most prevalent all over the world. In addition to being an extremely dangerous disease, malaria also exists. It claims the lives of several million people every year, the vast majority of them are youngsters. A vaccination against malaria is a possibility.

Is malaria a virus or bacteria?

Plasmodium, a genus of apicomplexan protists, is now known to be responsible for more than one species of the disease known as malaria. In order to finish their life cycle, members of the plasmodium genus need to have contact with both an infected mosquito and a vertebrate host. In vertebrates, the parasite begins its life cycle in liver cells, known as the exoerythrocytic stage, and then moves on to infect red blood cells, known as the erythrocytic stage. During each round of asexual reproduction, the parasite bursts from the blood cells and destroys them.

P. falciparum is the most lethal of the four species of Plasmodium that are known to infect people. It is responsible for fifty percent of all cases of malaria and is the leading (and most deadly) cause of disease-related deaths in tropical areas of the world. It was projected that malaria was responsible for approximately 400,000 deaths in 2015, most of which occurred in African children.

P. falciparum may infect and destroy more than half of a human’s circulating blood cells while the disease is progressing, which can result in severe anemia. Malaria is caused by this parasite. The immune system of the host mounts a massive inflammatory response in response to waste products released as the parasites burst from infected blood cells. This response includes episodes of fever (paroxysms) that induce delirium in the host. This occurs as the parasites lyse red blood cells, spilling parasite waste into the bloodstream. The Anopheles gambiae mosquito in Africa is responsible for transmitting the Plasmodium falciparum parasite to humans.

Malaria prevention relies heavily on the development of methods that either wipe out, sterilize, or just avoid coming into contact with very aggressive mosquito species. In a twist of fate, a form of genetic control has shown itself in regions of the world that are afflicted with malaria at epidemic levels. Malaria resistance is conferred by the presence of one copy of the HbS beta-globin allele in the patient. This genotype, when present in homozygous form, is responsible for the development of sickle cell disease, which is another negative outcome.
