Which classification of organisms is responsible for the disease malaria?
Malaria is caused by the Plasmodium parasite. The parasite can be spread to humans through the bites of infected mosquitoes. There are many different types of plasmodium parasite, but only 5 types cause malaria in humans.
Which organism is usually responsible for the most serious cases of malaria?
Plasmodium falciparum is the type of malaria that most often causes severe and life-threatening malaria; this parasite is very common in many countries in Africa south of the Sahara desert. People who are heavily exposed to the bites of mosquitoes infected with P. falciparum are most at risk of dying from malaria.
What are 3 types of malaria?
What Are the Different Types of Malaria Parasites?
- Plasmodium falciparum (or P. falciparum)
- Plasmodium malariae (or P. malariae)
- Plasmodium vivax (or P. vivax)
- Plasmodium ovale (or P. ovale)
- Plasmodium knowlesi (or P. knowlesi)
How many species of Plasmodium are there in malaria?
The classification of malaria can be established according to the strains of Plasmodium species. There are five common Plasmodium species that infect humans: P. falciparum, P. ovale, P. vivax, P. malariae, and P. knowlesi.
What are the four species of mosquitoes that cause malaria?
Malaria is caused by protozoa of the genus Plasmodium. Four species cause disease in humans: P falciparum, P vivax, P ovale and P malariae. Other species of plasmodia infect reptiles, birds and other mammals. Malaria is spread to humans by the bite of female mosquitoes of the genus Anopheles.
How are parasites involved in the lifecycle of malaria?
Lifecycle. Blood stage parasites are responsible for the clinical manifestations of the disease. The gametocytes, male (microgametocytes) and female (macrogametocytes), are ingested by an Anopheles mosquito during a blood meal . The parasites’ multiplication in the mosquito is known as the sporogonic cycle .
How is the epidemiology of malaria determined?
The epidemiology of malaria is determined by a complex interplay of multiple factors, including mosquito vector density, ambient temperatures (including other environmental conditions), population movements, altitude, parasitemia rates among endemic populations, and the species of the anopheline mosquito.
Is malaria a viral or a bacterial disease?
Malaria is a mosquito-borne parasitic infection spread by Anopheles mosquitoes. The Plasmodium parasite that causes malaria is neither a virus nor a bacterium – it is a single-celled parasite that multiplies in red blood cells of humans as well as in the mosquito intestine.
What is the prognosis for malaria?
About prognosis: The ‘prognosis’ of Malaria usually refers to the likely outcome of Malaria. The prognosis of Malaria may include the duration of Malaria, chances of complications of Malaria, probable outcomes, prospects for recovery, recovery period for Malaria, survival rates, death rates, and other outcome possibilities in…
What is the agent of malaria?
Organisms that belong to the genus Plasmodium are obligate eukaryotic parasites, best known as the etiological agent of human malaria.
Is malaria a viral disease?
Malaria is not a viral disease. Malaria is caused by the Plasmodium parasite. These parasites can be spread to humans through the bites of infected mosquitoes. There are many different species of plasmodium parasite, but only five species infect humans to cause malaria.
