What is the causative agent of malaria?

What is the causative agent of malaria?

Malaria is caused by a single-celled parasite of the genus plasmodium. The parasite is transmitted to humans most commonly through mosquito bites.

Which of the following agent is used to prevent malaria?

Chloroquine has been the standard antimalarial drug since its development during World War II and is used both for therapy and prophylaxis.

What is the causative agent and vector of malaria?

In the case of malaria, the vector is the anopheline mosquito and the disease-causing organism is the malaria parasite. Humans and anopheline mosquitoes are both considered to be the parasite’s hosts.

What is a causative agent?

Causative agents in infection are pathogens. Pathogens are micro-organisms that are capable of causing diseases or infections. If micro-organisms from a person’s own body cause an infection, it is called an endogenous infection.

What are antimalarial agents in medicinal chemistry?

Pamaquine, primaquine, and tafenoquine are antimalarial drugs that belong to a family named 8-aminoquinolines. Pamaquine is closely related to primaquine. Compared to primaquine, pamaquine is more toxic and less effacacious. Tafenoquine is currently in late clinical trials.

What is mechanism of action of antimalarial agent?

The quinoline-containing antimalarial drugs, chloroquine, quinine and mefloquine, are a vital part of our chemotherapeutic armoury against malaria. These drugs are thought to act by interfering with the digestion of haemoglobin in the blood stages of the malaria life cycle.

What are vectors name malarial parasite?

> Anopheles mosquito is the vector of the malarial parasite which is called .

Which classification of protozoans does the causative agent of malaria belong to?

Plasmodium, a genus of parasitic protozoans of the sporozoan subclass Coccidia that are the causative organisms of malaria. Plasmodium, which infects red blood cells in mammals (including humans), birds, and reptiles, occurs worldwide, especially in tropical and temperate zones.

What is the difference between causative agent and causative organism?

The diseases that are carried by insects and rodents and are caused by the bites of these organisms are known as vector borne diseases. Causative agents are organisms which are collectively referred as biological pathogen that causes a disease for example, a virus, parasite, fungus, or bacterium. etc.

Is a parasite a causative agent?

parasitic disease, in humans, any illness that is caused by a parasite, an organism that lives in or on another organism (known as the host). Parasites typically benefit from such relationships, often at the expense of the host organisms.

What are antimalarial agents discuss with example?

Antimalarial Agents Antimalarial drugs have a variety of targets and mechanisms of action. Many, like chloroquine, amodiaquine, mefloquine, and quinine act on heme in the parasitic food vacuole. In this way, they prevent the polymerization of hemoglobin, which can be toxic to the plasmodium parasite.

What is the classification of malaria?

Malaria is usually classified as asymptomatic, uncomplicated or severe. Asymptomatic malaria can be caused by all Plasmodium species; the patient has circulating parasites but no symptoms. Uncomplicated malaria can be caused by all Plasmodium species. Symptoms generally occur 7-10 days after the initial mosquito bite.

Which protozoa is responsible for malaria?

There are 5 parasite species that cause malaria in humans, and 2 of these species – Plasmodium falciparum and Plasmodium vivax – pose the greatest threat. In 2020, nearly half of the world’s population was at risk of malaria.

What is the genus of the causative agent of malaria in what group does it belong?

The causative agents of malaria are unicellular protozoan parasites belonging to the genus Plasmodium. These parasites infect not only humans but also other vertebrates, from reptiles and birds to mammals.
