Definition of plasmodium 1a : a motile multinucleate mass of protoplasm resulting from fusion of uninucleate amoeboid cells also : an organism (such as a stage of a slime mold) that consists of such a structure. b : syncytium sense 1. 2 : a sporozoan parasite (genus Plasmodium) that is the causative agent of malaria.
What is Plasmodium in biology class 10?
Plasmodium is a genus of parasitic protozoans that fall under the family Apicomplexa, the class Aconoidasida and the sporozoan subclass Coccidia. Plasmodium is known to infect the red blood cells in mammals like humans, birds, reptiles and so on.
What is Plasmodium and its function?
The malaria parasite Plasmodium utilizes specialized proteins for adherence to cellular receptors in its mosquito vector and human host. Adherence is critical for parasite development, host cell traversal and invasion, and protection from vector and host immune mechanisms.
What is Plasmodium Class 9?
Plasmodium is a genus of parasitic protozoans that are known to infect the red blood cells in mammals and causes an infectious disease called malaria.
Why is it called Plasmodium?
In 1885, zoologists Ettore Marchiafava and Angelo Celli reexamined the parasite and termed it a member of a new genus, Plasmodium, named for the resemblance to the multinucleate cells of slime molds of the same name.
What is the other name of Plasmodium?
Plasmodium malariae (or P. malariae)
Is Plasmodium a virus?
Malaria is a mosquito-borne parasitic infection spread by Anopheles mosquitoes. The Plasmodium parasite that causes malaria is neither a virus nor a bacteria – it is a single-celled parasite that multiplies in red blood cells of humans as well as in the mosquito intestine.
Who discovered Plasmodium?
Dr. Alphonse Laveran, a military doctor in France’s Service de Santé des Armées (Health Service of the Armed Forces). The military hospital in Constantine (Algeria), where Laveran discovered the malaria parasite in 1880.
What is Plasmodium Class 11?
Hint: Plasmodium is a parasite and is the causative organism of malaria. It requires two hosts to complete its life cycle- female Anopheles mosquito and human beings.
Which disease is caused by Plasmodium?
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.
How is Plasmodium transmitted?
All four human Plasmodium species are transmitted by the bite of an infected female Anopheles mosquito. About 60–100 anopheline species are able to transmit malaria in the world. Infected humans remain infectious to mosquitoes as long as they carry mature gametocyte forms of plasmodium.
Is Plasmodium a fungi?
plasmodium, in fungi (kingdom Fungi), a mobile multinucleate mass of cytoplasm without a firm cell wall. A plasmodium is characteristic of the vegetative phase of true slime molds (Myxomycetes) and such allied genera as Plasmodiophora and Spongospora.
What is the shape of Plasmodium?
Gametocytes of Plasmodium falciparum are crescent- or sausage-shaped, and are usually about 1.5 times the diameter of an RBC in length.
Where is Plasmodium found?
Plasmodium, which infects red blood cells in mammals (including humans), birds, and reptiles, occurs worldwide, especially in tropical and temperate zones. The organism is transmitted by the bite of the female Anopheles mosquito. Other insects and some mites may also transmit forms of malaria to animals.
Where is Plasmodium from?
Chimpanzees and gorillas harbour six Laverania spp. as well as Plasmodium vivax. Plasmodium falciparum arose in humans after the acquisition of the parasite from a gorilla. Plasmodium vivax is a bottlenecked parasite lineage that originated in African apes.
Is Plasmodium Gram positive or negative?
Plasmodium are not bacteria and as such do not have a uniform gram stain pattern, for example P. vivax is known to display a gram positive or gram negative stain depending on the conditions.
What are the 3 stages of malaria?
The first is a 15-to-60 minute cold stage characterized by shivering and a feeling of cold. Next comes the 2-to-6 hour hot stage, in which there is fever, sometimes reaching 41°C, flushed, dry skin, and often headache, nausea, and vomiting.
What are the four species of Plasmodium?
Four species of Plasmodium cause human malaria, P. falciparum, P. malariae, P. ovale, and P.
Is Plasmodium A parasite?
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.
How does malaria cause death?
Malaria may result in not having enough red blood cells for an adequate supply of oxygen to your body’s tissues (anemia). Low blood sugar. Severe forms of malaria can cause low blood sugar (hypoglycemia), as can quinine — a common medication used to combat malaria. Very low blood sugar can result in coma or death.
What are the four causes of malaria?
There are four kinds of malaria parasites that can infect humans: Plasmodium vivax, P. ovale, P. malariae, and P. falciparum.
Is there a malaria vaccine?
A malaria vaccine is a vaccine that is used to prevent malaria. The only approved vaccine, as of 2021, is RTS,S, known by the brand name Mosquirix. In October 2021, the WHO for the first time recommended the large-scale use of a malaria vaccine for children living in areas with moderate-to-high malaria transmission.
What is the primary host of Plasmodium?
Malaria parasites are micro-organisms belonging to the genus Plasmodium. The primary host of the parasite is the Anopheles mosquito and vertebrates (primarily humans). Malaria parasites are transmitted from the mosquito to its human host in the form of sporozoites during a blood meal.
What is difference between Plasmodium and Plasmodium?
Plasmodium is a sporozoan parasite that causes malaria. Whereas the plasmodium is a wall-less mass of multinucleated protoplasm of plasmodial slime molds. Was this answer helpful?
Is Plasmodium a protozoa?
The genus Plasmodium belongs to a larger group of protozoans called the Apicomplexa, part of the superphylum Alveolata that also includes dinoflagellates and ciliates .
