Blood Is Essential For Efficient And Effective Bodily Function

Mosquitoes pass malaria to humans through their salivary glands. Once the parasites have entered the blood stream, they go to the liver. In the liver they mature and undergo reproduction, forming merozoites. These merozoites enter the blood stream and inject themselves into red blood cells. Once inside the blood cells, they reproduce rapidly and within forty-eight to seventy-two hours, the blood cell bursts, releasing hemoglobin into the blood stream. It is the destruction of these blood cells and the hemoglobin released into the blood stream that actually causes most of the symptoms.

Annually, 200 million malaria cases are contracted and of these, 90% occur in Sub-Saharan Africa. Approximately one million people die annually, making plasmodium falciparum the most deadly parasitic disease. Contraction of plasmodium falciparum begins when a female Anopheles mosquito injects sporozoites, an early form of plasmodium falciparum, into the host. This sporozite is then transported to the human liver where it undergoes asexual reproduction producing merozoites. The merozoites invade other liver cells and enter the host’s bloodstream, where they invade erythrocyte. After the infection of the erythrocyte, the merozoite is transformed into a trophozoite, which then begins asexual reproduction near the nucleus to form a schizont in the erythrocytic cell. The schizont then asexually reproduces to produce mononucleated merozoites. When the erythrocytic cell ruptures due to the 3,000-4,000 merozoites produced, symptoms of fever and chills are induced within the host. This life cycle is extremely damaging to children; persons under the age of 5 account for 86% of malaria fatalities. Malaria has other characteristic effects, such as yellowing of the skin/eyes (jaundice), sweating, vomiting, weakness, and nausea. Current mortality rates in Africa are 9.33% per 1000 children, which represent 28.2% of all fatalities for those under five. The story changes dramatically as the host

Malaria or other similar diseases like malaria has been recognized and encountered by humans for more than 4,000 years. Malaria is caused by the genus Plasmodium parasites, which enter the human body and are transmitted to people through the bite of a mosquito infected with the parasite (Q&A, Malaria). Once the parasite enters the human body, the parasites multiply in the liver and then infect red blood cells. The malaria parasite was first discovered on November 6, 1880, by a French army surgeon named Charles Louis Al phonse Laveran. While stationed in

There are five types of mosquitos that can carry the disease; P. falciparum, P. Vivax, P. Ovale, P. Knowlesi, and P. Malariae (Marshall & Taylor, 2009). The two diseases that have the most focus are the P. vivax which is most widely contracted, and the P. Falciparum which is the most fatal (Center for Disease Control, 2017). The life cycle of the disease starts with the bite of a mosquito called the anopheles, which transmits the disease. While there are hundreds of different types of mosquitoes anopheles is the only one that carries the parasitic protozoa. The bite of a mosquito injects sporozoites into the blood stream where it travels quickly to the liver since they have a short life span (Frevert, 2004). Once at the liver it infects the liver cells and replicates itself to mature into schizonts which ruptures into merozoites. After replication the merozoites burst from the liver cells into the blood stream and begin to invade the erythrocytes (red blood cells), once in the erythrocytes they again replicate completely filling the cell until the parasite ruptures the erythrocytes and releases toxins and merozoites into the bloodstream. The parasites are then separated into gametocytes (male/female), where they are released by the blood stream as plasmodium which can be acquired from another anopheles mosquito by biting the human host to start the cycle

Malaria is transmitted through the bite of an infected Anopheles mosquito. The saliva of the mosquito enters through the blood stream and then goes into the liver, where the parasites grow and reproduce. The typical symptoms of malaria are fever, tiredness, vomiting, and headaches. In more severe cases it can cause yellow skin, seizures, comas or death. Symptoms usually begin ten to fifteen days after being bitten. If it is not properly treated, the disease may come up again months later. Malaria can only be transported through an already infected mosquito or if you get infected blood during a transfusion. It can also be transported from a mother to baby during pregnancy. Mosquitoes can get infected from biting an already infected human or animal. The bite of an infected mosquito goes into the bloodstream and into the red blood cells. The

The Plasmodium Protozoa also known as malaria, is one of the most common infectious diseases on the planet. It is spread by infected mosquito bites. The symptoms are fever, joint pain, anemia, and fatigue. Malaria is a very infectious and serious disease, killing several million people each year.

Malaria affects more children under 5 years. It cannot affect them the first 2 months because of the immunity that she gives to her baby during pregnancy. At the beginning symptoms of malaria appears on the child with high fever leads to chilling in the body and other symptoms like rapid breathing, stomach pain, loss of appetite, and sleeplessness. Symptoms of malaria starts appear from the first 10 days to four weeks. Most probably this disease leading to death for children, because it is difficult to treat this dangerous

After infection malaria can sit dormant for up to a month while other species of the parasite will will cause a shorter period of dormancy, typically lasting from a couple of days to seven days. After the dormant or incubation periods have finished is when the disease starts its symptoms. Diagnosis is confirmed usually by manual microscope blood sample analysis. While there are a number of different kinds of anti-malarials, one kind, called “chloroquine” is mainly used. If treated urgently and correctly, the prognosis of malaria is very good for most of the plasmodium types. P. falciparum can be a bit of a problem, but is also usually not fatal. The reason malaria is so fatal is because people who contract, especially in the third world, do not always have a means to seek medical care.

Around 300-600 million people suffer from malaria each year, and over one million people die from this disease every year, mostly children younger than five. This disease is endemic to over 100 countries in Africa, Asia, Latin America, the Middle East, and the South Pacific, almost 40% of the world population. Malaria is caused by a parasite that is transferred by the bite of an infected female Anopheles mosquito. The most deadly form of malaria is known as Plasmodium falciparum because almost all deaths from malaria are caused by this specific one. In addition to being the deadliest form of malaria, Plasmodium falciparum destroys red blood cells along with causing complications with the kidneys, lungs, and brain. In more serious cases, it

They then begin to attack and invade the red blood cells in which they will reproduce asexually and continue to release newly-formed merozoites which constantly compound upon themselves and infect more and more red blood cells, causing the symptoms associated with Malaria. Occasionally, these infected red blood cells will replicated into sexual forms of the parasite (known as gametocytes) that will continually run rampant in the blood stream until another mosquito comes along and feeds upon the same host. From here, the mosquito will ingest those gametocytes which will then produces thousands of active forms of sporozoites that will be in turn implanted into a different host’s liver and bloodstream upon being bitten by that mosquito. If this disease is left untreated and mosquitos are able to live freely, Malaria will certainly proliferate in whatever area it is established in. (NIH 2012)

Malaria is a serious disease caused by a parasite. Infected mosquitoes spread it. Malaria is very common throughout the world. In the United States, the main risk is to persons traveling to tropical and subtropical countries where malaria is a problem. There are four different types of malaria caused by four related parasites. The most deadly type occurs in Africa south of the Sahara Desert. The symptoms characteristic of malaria include fever, chills, muscle aches, and headache. Cycles of chills, fever, and sweating that recur every 1, 2 or 3 days are typical. There can sometimes be vomiting, diarrhoea, coughing and yellowing (jaundice) of the skin and whites of the eyes. The treatment for malaria depends upon the geographic area where a person has been infected with the disease. Different areas of the world have malaria types that are resistant to certain medications.

Furthermore, malaria parasites have a complex life cycle in which they infect humans and are transmitted by Anopheline mosquitoes.The completion of the parasite life cycle was a success and requires specific molecular interactions between the parasite and host or vector tissues. It may be

Malaria parasites infect two types of hosts: the female Anopheles mosquitoes and vertebrates. The mosquitoes do not suffer from the presence of the parasite, instead it acts as a parasite “vector”. The female Anopheles mosquito ingests the parasite in the form of gametocytes from a malaria infected host (CDC, 2012a). The infected human RBCs bursts when they reach the mosquitoes gut and release gametocytes, which then develop into mature sex cells called gametes (National Institutes of Health [NIH], 2012). The gametocytes are male, microgametocytes, and female, macrogametocytes, which fuse together forming diploid zygotes (CDC, 2012a). The zygotes develop into actively moving ookinetes that can burrow into the mosquitoe’s midgut wall and form oocysts (NIH, 2012). The oocysts usually grow, rupture, and release sporozoites (CDC, 2012a). Sporozoites travel from

Malaria, also known as Plasmodium infection, is caused by the plasmodium parasite. If malaria is treated within its initial stages of development it can be cured. The symptoms usually start to exhibit within 10 days to 4 weeks after the infection. The initial symptoms of malaria include high fever, nausea, sweating, chills, muscle aches, and vomiting. The symptoms of malaria mimic certain flu symptoms in the initial stages, which is why many cases go unheard until it is in its detrimental stage. If malaria is left untreated it can cause severe anemia and cerebral malaria. Cerebral malaria is when the capillaries carrying blood into the brain are blocked, which can cause a coma and eventually death. The most vulnerable among populations are pregnant women and children under the age of five. Their immunity is the weakest and this allows them to be more susceptible to

What is the gift that I can give that will save someone’s life? Why of course, it is the gift of giving blood. Blood is an amazing fluid that feeds, takes away the waste and carries oxygen to all cells in our body (Holt, Rinehart, and Winston 182). So, why give blood and what do I need to do to contribute. Blood donations are used in various ways, such as transfusions, research, medical emergencies or trauma. Blood drives take place day in and day out to help supply the constant need of blood. Knowing some facts and the use of blood, may change my mind on why I should give. Blood is our body’s transportation system of nutrients and can be a gift for saving someone’s life.
