MALARIA
Symptoms: These symptoms can include but are not limited to:
-Headaches
-Vomiting
-Diarrhoea
-Shivering
-Joint pains
-Jaundice
-Muscle pains
-Sweats and even the general feeling of just being unwell.
Life cycle: ----First, malaria is transported by the female Anopheles mosquito by feeding on the its victim( ideally humans now) and while it does this it transmits the sporozoites form of the parasites into the body.
-When the mosquito bites, some sporozoites are transmitted with the saliva during thmeal
-After 30 minutes, the sporozoites go into the liver where they multiple for 5-7 days until they form thousands of merozoites.
- The merozoites burst out of the liver and into the blood stream infecting the blood cells
-In the red blood cell the parasite normally takes 2 days to multiple more merozoites
-After that the infected blood cells burst which release new merozoites to infect more cells
- Some of the merozites invade more red blood cell and develop into gametocytes which is the sexual stage of the parasite
- The gametocytes are then taken up by another mosquito during a blood meal
- Then inside the mosquito the gametocytes develop into gametes and join together to form a zygote
-After fertilization the gamete develops into a motile ookinete
-The ookinete then burrows through the wall of the mosquitos stomach wall and positions itself
-The ookinete then develops into an oocyst and divides to produce thousands of sporozoites
-After 5-7 days the sporozoites then move into the salivary glands where they prepare to infect another host
Transmission: Malaria is transmitted through vectors. They could be animals or insects such as female Anopheles mosquitos. These vectors carry an organism called plasmodium which is the actual cause of the disease which is spread around by the vectors.

Worldwide importance: Malaria is an important disease because it is in fact

    One factor that is commonly not taken into consideration when talking about site specificity and the behavior of the parasite is the parasites perspective. A few factors that can affect behavior of the parasite can be age of infection, immune response, increase in size of parasite population or simply a change in the host diet. A lot of the times it is thought that parasites take a certain pathway that lead to their specific site, and it is often misunderstood for that fact that they have two different paths to choose and they end up taking one that becomes fixed. However, there is more involved in this than just simply making a decision. It can be the environment made the parasite choose that path or because it there was a higher reproductive success in that specific path. I believe there is a lot more involved in the path that parasites take. Furthermore, a important concepts that need to be taken into consideration when talking about reproductive success is specific trade off the parasite has to give. Although the parasite wants to produce more eggs, there is often more pathology also involved with the bigger body. Due to these specific tradeoff that are involved with the increased fitness of the parasite there may be more involved with the specific site and behavior of the parasite. Next, when it comes to choosing the specific resources within…

    Parasite Host Relationship

    • 1602 Words
    • 7 Pages

    Throughout this course we have discussed the ways in which parasites manage to reside in a host, resist the immune system of the host, and keep the host alive long enough to successfully reproduce. Their ability to do this very thing has made them expert survivalists, and have allowed for adaption to the host. Researchers now know depending on the host, as well as the parasite, the form in which the parasite enters their host varies and will initiate a varying immune response. By studying parasite life cycles researchers have begun identifying the ways the typical immune system will respond to certain forms and species of parasites. By identifying the magnitude of the response, as well as the type of response researchers hope to develop more efficient vaccines and treatments for parasite burden, but in doing so have discovered the parasite host relationship offers information that can be utilized to treat immune related diseases in…

    Mosquitoes are small insects that have a very thin body. Mosquitoes can be found anywhere except for Antarctica. There are about 170 different species of mosquitoes in all of North America. To grow, mosquitoes need a small area of stagnant water. Mosquitoes have been known to breed in fresh water, salt-water marshes, or water found in old tires or plastic containers. The mosquito life cycle has 4 significant stages. They go from eggs to larvae to pupae and finally to adult. Only female mosquitoes can bite. Male mosquitoes feed on mostly flower nectar. The females, however, require a blood meal to lay their eggs.…
