What is the Plasmodium which causes human parasite?
Plasmodium is a parasite which causes the infection Malaria. It is transmitted via the bites of infected mosquitoes. If malaria is not treated, it can quickly become life threatening by disrupting the blood supply to vital organs.
What are some harmful protists?
Plasmodium. Bring malaria through their mosquito vector. Giardia. Cause intestinal problems for dogs and sometimes humans. Trypanosoma. Causes sleeping sickness.It is very harmful protista beause it can cause cancer.
Malaria?
DefinitionMalaria is a parasitic disease that involves high fevers, shaking chills, flu-like symptoms, and anemia.Alternative NamesQuartan malaria; Falciparum malaria; Biduoterian fever; Blackwater fever; Tertian malaria; PlasmodiumCauses, incidence, and risk factorsMalaria is caused by a parasite that is transmitted from one human to another by the bite of infected Anophelesmosquitoes. In humans, the parasites (called sporozoites) travel to the liver, where they mature and release another form, the merozoites. These enter the bloodstream and infect the red blood cells.The parasites multiply inside the red blood cells, which then rupture within 48 to 72 hours, infecting more red blood cells. The first symptoms usually occur 10 days to 4 weeks after infection, though they can appear as early as 8 days or as long as a year after infection. Then the symptoms occur in cycles of 48 to 72 hours.The majority of symptoms are caused by the massive release of merozoites into the bloodstream, the anemia resulting from the destruction of the red blood cells, and the problems caused by large amounts of free hemoglobin released into circulation after red blood cells rupture.Malaria can also be transmitted from a mother to her unborn baby (congenitally) and by blood transfusions. Malaria can be carried by mosquitoes in temperate climates, but the parasite disappears over the winter.The disease is a major health problem in much of the tropics and subtropics. The CDC estimates that there are 300-500 million cases of malaria each year, and more than 1 million people die. It presents a major disease hazard for travelers to warm climates.In some areas of the world, mosquitoes that carry malaria have developed resistance to insecticides. In addition, the parasites have developed resistance to some antibiotics. This has led to difficulty in controlling both the rate of infection and spread of this disease.Falciparum malaria, one of four different types of malaria, affects a greater proportion of the red blood cells than the other types and is much more serious. It can be fatal within a few hours of the first symptoms.SymptomsAnemiaChillsComaConvulsionFeverHeadacheJaundiceMuscle painNauseaStools, bloodySweatingVomitingSigns and testsDuring a physical examination, the doctor may identify an enlarged liver or an enlarged spleen. Malaria blood smears taken at 6 to 12 hour intervals confirm the diagnosis.TreatmentMalaria, especially Falciparum malaria, is a medical emergency requiring hospitalization. Chloroquine is a frequently used anti-malarial medication, but quinidine or quinine plus doxycycline, tetracycline, or clindamycin; or atovaquone plus proguanil (Malarone); or mefloquine or artesunate; or the combination of pyrimethamine and sulfadoxine, are given for chloroquine-resistant infections. The choice of medication depends in part on where you were when you were infected.Aggressive supportive medical care, including intravenous (IV) fluids and other medications and breathing (respiratory) support may be needed.Expectations (prognosis)The outcome is expected to be good in most cases of malaria with treatment, but poor in Falciparum infection with complications.ComplicationsDestruction of blood cells (hemolytic anemia)Liver failure and kidney failureMeningitisRespiratory failure from fluid in the lungs (pulmonary edema)Rupture of the spleen leading to massive internal bleeding (hemorrhage)Calling your health care providerCall your health care provider if you develop fever and headache after visiting the tropics.PreventionMost people living in areas where malaria is common have acquired some immunity to the disease. Visitors will not have immunity, and should take preventive medications. It is important to see your health care provider well before your trip, because treatment may begin is long as 2 weeks before travel to the area, and continue for a month after you leave the area. The types of anti-malarial medications prescribed will depend on the area you visit. According to the CDC, travelers to South America, Africa, the Indian subcontinent, Asia, and the South Pacific should take one of the following drugs: mefloquine, doxycycline, choroquine, hydroxychoroquine, or Malarone.Even pregnant women should take preventive medications because the risk to the fetus from the medication is less than the risk of acquiring a congenital infection.People on anti-malarial medications may still become infected. Avoid mosquito bites by wearing protective clothing over the arms and legs, using screens on windows, and using insect repellent.Chloroquine has been the drug of choice for protection from malaria. But because of resistance, it is now only suggested for use in areas where Plasmodium vivax, P. oval, and P. malariae are present. Falciparum malaria is becoming increasingly resistant to anti-malarial medications.For travelers going to areas where Falciparum malaria is known to occur, there are several options for malaria prevention, including mefloquine, atovaquone/Proguanil (Malarone), and doxycycline.Travelers can call the CDC for information on types of malaria in a given geographical area, preventive drugs, and times of the year to avoid travel.

What of the is not a fungal infeccton?
A siren is not a fungal infection.
What are vectors used for in controlling maleria?
In relation to malaria, the word 'vector' refers to the means by which a disease is transmitted, specifically an organic host. So bats, rats, ticks, fleas and Outbreak monkeys can all be vectors. In malaria's case, the vector is the mosquito. So you don't really use vectors to control malaria, but rather try to control malaria by stopping on the vector, i.e. get yourself a mosquito net or don't trek through the jungle.
Name the causative organism of malaria?
Malaria is caused by 1 of the 5 species of the plasmodium parasite. The five types of mosquitoes responsible for malaria are: Plasmodium falciparum, Plasmodium vivax, Plasmodium knowles, Plasmodium ovale and Plasmodium malariae. The mosquitoes infect humans and within weeks to months they grow and multiply in the body, eventually causing symptoms which can include fever, coma and death.
