Malaria


     Malaria parasites have been with us since the beginning of time, and
fossils of mosquitoes up to thirty million years old show that malaria’s vector
has existed for just as long. The parasites causing malaria are highly specific,
with man as the only host and mosquitoes as the only vector. Every year,
300,000,000 people are affected by malaria, and while less than one percent of
these people die, there are still an estimated 1,500,000 deaths per year. While
Malaria was one of the first infectious diseases to be treated successfully with
a drug, scientist are still looking for a cure or at least a vaccination today
(Cann, 1996). Though many people are aware that malaria is a disease, they are
unaware that it is life threatening, kills over a million people each year, and
is a very elusive target for antimalarial drugs (Treatment of Malaria, 1996).
     Being a very specific disease, malaria is caused by only four protozoal
parasites: Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, and
Plasmodium malariae. Not only is the disease specific, but the parasites are
too, with only 60 of 380 species of female Anopheles mosquitoes as vectors.
With the exception of Plasmodia Malariae which may affect other primates, all
parasites of malaria have only one host, Homo sapiens. Because some mosquitoes
contain substances toxic to Plasmodium in their cells, not all species of
mosquitoes are vectors of Plasmodium. Although very specific, malaria still
causes disruption of over three hundred million people worldwide each year (Cann,
1996).
     The life cycle of the parasite causing malaria exists between two
organisms, humans and the Anopheles mosquito. When a female mosquito bites a
human, she injects an anticoagulant saliva which keeps the human bleeding and
ensures an even flowing meal for her. When the vector injects her saliva into
the human, it also injects ten percent of her sporozoite load. Once in the
bloodstream, the Plasmodium travel to the liver and reproduce by asexual
reproduction. These liver cells then burst releasing the parasites back into
the bloodstream where they then enter red blood cells. Here, the Plasmodium
feed on hemoglobin and reproduce again by asexual reproduction. Afterwards, the
red blood cells burst and release the parasites. Some of the para...

...ion people annually. As
the Plasmodium parasites mutate more and more to resist the effect of
antimalarials, it becomes harder for scientist to find a cure (Treatment of
Malaria, 1996). Over forty percent of the world’s population still at risk from
this deadly disease, is yearning for a cheap, effective vaccine (Cann, 1996).

Optimizing Chloroquine to Make a Better Drug to Fight Malaria Essay

- Optimizing Chloroquine to Make a Better Drug to Fight Malaria Abstract: Malaria has haunted man for centuries. Humanities experiments in drugs allowed for the discovery of chloroquine, perhaps the most successful cure against the parasitic infection. However, a new strain of malaria, plasmodium falciparum, has proven to be resistant against chloroquine and other cures we have for this virulent disease. Should man then cast aside this antique drug. Not before trying to optimize it to once again combat malaria....   [tags: Biology Medical Malaria Disease]

Malaria- Falciparum Malaria Essay

- The most common strain of malaria, falciparum malaria, must be treated in the hospital since it is considered a medical emergency. The mode of treatment including the type of drugs administered depends on the severity of the disease and the place in which the malaria was contracted. The basic treatment for all strains of malaria (except falciparum) is normally chloroquine, which is administered for 3 days by mouth. Since most falciparum strains are resistant to chloroquine, a combination of tetracycline and quinine is normally used to treat them....   [tags: Medical Emergency, Hospital, Health, Treatment]

Malaria Essay

- Malaria is regarded as one of the world's deadliest tropical parasitic diseases. It claims more lives than any other communicable disease except tuberculosis. In Africa and other developing countries, it also accounts for millions of dollars in medical costs. Malaria, however, is a curable disease if promptly diagnosed and adequately treated. Malaria is a mosquito-borne disease caused by the parasite plasmodium. In recent years, most cases in the U.S. have been in people who have acquired the disease after travelling to tropical and sub-tropical areas....   [tags: essays research papers fc]

Malaria Essay

- The Disease…………… That lead everyone in for a great awaking. Malaria in humans is caused by a protozoon of the genus Plasmodium and the four subspecies, falciparum, vivax, malariae, and ovale. The species that causes the greatest illness and death in Africa is P. falciparum. The disease is transmitted by the bites of mosquitoes of the genus Anopheles, of which the Anopheles gambiae complex (the most efficient) is responsible for the transmission of disease in Africa. Fever is the main symptom of malaria....   [tags: essays research papers fc]

Malaria Essay

- Malaria (also called biduoterian fever, blackwater fever, falciparum malaria, plasmodium, Quartan malaria, and tertian malaria) is one of the most infectious and most common diseases in the world. This serious, sometimes-fatal disease is caused by a parasite that is carried by a certain species of mosquito called the Anopheles. It claims more lives every year than any other transmissible disease except tuberculosis. Every year, five hundred million adults and children (around nine percent of the world’s population) contract the disease and of these, one hundred million people die....   [tags: essays research papers fc]

Malaria Essay

- Malaria There are a great number of diseases that are endemic in many of the poorer, developing nations due to the lack of sanitation and disease prevention programs in these areas. The steady increase of malaria epidemics in many of the African countries is a point of great concern, because this continent is home to 90% of the world’s total cases of this particular disease. Malaria gets its name from “mal aria,” meaning bad air, because patients used to blame the sudden illness on the poor air quality of the nearby swamps....   [tags: Exploratory Essays Research Papers]

Malaria Essay

- Abstract: Malaria, which has killed more people than those killed by all the war and all the plagues combined, is caused by a small protozoan parasite of the genus Plasmodium that resides within cells in the bloodstream to mature and avoid detection. There are four main species of Plasmodium that cause malaria. These species of the parasite infect humans and female anopheline mosquitoes at different stages in their life cycle. When an infected female anopheline mosquito feeds upon the blood of the vertebrate, the parasite is transferred through the saliva, into the body of the vertebrate host....   [tags: Biology Medical Biomedical Disease]

Essay about Understanding Malaria

- Understanding Malaria For several years, I have had an interest in virology and the spread and characteristics of various infectious diseases. Though it makes sense not to possibly induce a state of panic by informing individuals of illnesses that are not native to the area they live in and that they are not likely to contract, I have always liked to remain informed out of my own curiosity and interest. Thus, I have decided to write about malaria. Malaria kills more people than any communicable disease except for tuberculosis....   [tags: Research Papers Term Papers]
