What is the life cycle of malaria?
The life cycle of malaria describes the various phases in the development and reproduction of malaria, an infectious disease that bears mosquitoes and caused by a number of protists known as Plasmodium . Five different varieties Plasmodium is able to infect people; Plasmodium falciparum tends to cause the most serious cases of infection. Malaries kill millions of people every year, although they were mostly controlled in developed countries. Most of the deadly cases of malaria in the world occur in young children in Sub -Saharan Africa. The high level of malaria in a given area may be an important obstacle to economic development.
The first phase in the life cycle of malaria occurs when mosquito Anopheles Infected Plasmodium bites a sensitive person. The infected mosquito injects prolonged, moving cells known as sporozoites into the bloodstream. After entering the body of the man of sporozoity More into the liver of man, where they are divided and multiply into the next phase of the life cycle of malaria - measoites.
After the period from weeks to years, although usually between two and several months, measoites leave the liver and enter the bloodstream host, where they infect red blood cells and begin to multiply. Red blood cells have cracked and release toxins in the host body. During this phase of malaria life cycle, symptoms such as fever, chills and headache are beginning to present themselves. In severe cases, especially those concerning infection using Plasmodium Falciparum , victims may experience hallucinations, coma and eventually death.
There is also a sexual phase in the life cycle of malaria. Some of the mezoites that infect red blood cells are simply not spolled and spread; Instead, they develop on gametocytes that can produce both male and female gametes or sex cells. These red blood cells do not suffer; They remain intact and contain gametocytes. However, these gametocytes are unable to produce gamets in the human body, soE new Plasmodium cannot form within blood cells.
The next phase of the life cycle of malaria occurs when mosquito draws blood from an infected individual. Gametocytes are able to produce gamets in the body of mosquitoes. Gametocytes produce male and female games that combine and create a new generation of sporozoit. After biting another person, the mosquito is able to expand the parasite, infect the new person sporozoits and restart the life cycle of malaria.
