Life Cycle of the Malaria Parasite - What is the disease: Malaria is a mosquito-borne infectious disease to humans and other animals which is caused by parasitic protozoans. You develop it by a female infected mosquito with parasites transmitting its bite through the skin. This can cause severe redness on the area and continuous itching which can cause the bite to inflame. Malaria is quite rare in countries such as the United States, but it is most commonly found in countries such as Southern Asia and Africa. It is said that there is 20 species around the world but there are 4 most common species that cause the disease in humans a few are known as: Plasmodium falciparum, this is the most deadly out of all 4 to humans this lies...   [tags: mosquito, parasitic protozoans]

The Parasite and the Host - Parasitical relationships are commonplace in nature. A parasite attaches itself to a host and gradually benefits while the host's assets are drained. When the initial host's assets are completely depleted, the parasite moves on to another to leech off of while the host is left to gradually lose its life. This type of parasitical relationship is highlighted in Franz Kafka's short story, The Metamorphosis, in the relationships of members of the Samsa family.

How Malaria Is Passed from Person to Person - Because the malaria parasite exists in human red blood cells which form part of blood, it is possible for malaria to be passed on from one person to the next via organ transplant, shared use of sharp objects that come in contact with blood such as knives, needles and syringes; it can also be passed on through blood transfusion. An infected mother can also card malaria on to her unborn baby during the process of birth (delivery).Malaria passed on in this matter is called congenital malaria.
