Parasite Essay

predators come in different forms one of them is called a parasite, it derives nutrition from its host. These parasite feed of from the host in order for it to survive (Mader 2010) Also, these parasites cause disease and sickness. There are three key forms of parasites which may stimulate disease in humans: protozoa, helminths, and ectoparasites. (CDC). types of parasites around the world, but for this essay will compare two parasites which are Toxoplasma gondii genus (is a type of roundworm)

and a major public health problem worldwide. Billions of people are at risk of infection in 109 countries. Annually, there are an estimated 250 million cases of malaria leading to about one million deaths. Malaria is a disease that is caused by parasites in the red blood cells of a human body, and is usually transmitted by the bite of certain species of mosquitos. Malaria symptoms were first described in ancient Chinese medical writings. Around late 2000 BCE, several characteristics of malaria were

disease related to millions of deaths around the world, precisely in Africa. This paper discusses malaria which is caused by parasites transmitted by mosquitoes. This report gathers medical and scientific information and gives general clarification about the disease from journals, articles, and websites. This research shows an overview of the disease, the types of parasites, that include Plasmodium falciparum, Plasmodium ovale, Plasmodium malariae, Plasmodium vivax, and Plasmodium knowlesi. It also

Description of Malaria Malaria is caused by parasite, thus anti-biotic will not have effects on them. Infected mosquitoes spread it (Mayo Clinic). It can also be spread from mother to children through blood. However having a malaria-infected person nearby will not cause the disease to spread (WebMD). Malaria remains a prevalent health issue in the tropical area (WHO). In 2015, there are 214 million malaria cases reported, and the mortality rate is 60% (WHO). Typical symptoms of malaria include fever

Biology An intestinal infection that is found worldwide, Giardiasis is one of the most prevalent waterborne diseases in the United States and many other parts of the world. Often a major diarrheal disease, Giardia is caused by an aquatic, microscopic parasite found globally, however it most often found in regions of poor sanitation that only have access to unsafe water. Few examples of symptoms that are common with Giardiasis are asymptomatic colonization or acute or chronic colonization or acute/chronic

Facilitated largely by increased political commitment, an up-scaling of World Health Organisation (WHO) vector control measures and expansion of the so-called “artemisinin-based combination therapies”, the past decade has seen remarkable progress in the global effort against malaria. In fact, latest figures approximate that global investments in malaria control have amassed to a 42% reduction in the diseases’ mortality rate between 2000 and 2012, saving an estimated 3.3 million lives during this

that can show degrees of parasite resistance (Howard and Minchelle 1990). The Contagion Indicator Hypothesis created by DJ Able (1996) proposes that “the degree of expression of variable male traits indicates a male’s intensity of associatively transmittable parasites, and thus the risk a choosing female and her offspring will acquire these parasites.” This means that a female would select a male that will improve her direct and indirect benefits from contacting parasites. This study will examine

Plasmodium is a parasite with over 100 species, but only four directly affect humans(“Malaria Parasites”). This parasite affects the circulatory system, or cardiovascular system. It’s structured of many things, and some structures are in common with animals or human cells. Even though it’s microscopic in size, it can cause a lot of damage. The parasite gets into the body from mosquitoes and infects the bloodstream of the circulatory system. Plasmodium affects the cardiovascular system. The cardiovascular

Why this crab is showing such odd behavior can be explained by looking into the parasite that has infected it, Sacculina carcini. S. carcini is a type of parasite that has a special characteristic, it can manipulate its host’s physical body and behavior. This parasite tricks its host into helping it survive and reproduce. In this case Sacculina carcini change their host, the crab, or Carcinus maenas. The parasite begins its life as a larvae exiting a host and then wondering the sea, looking for

Mainly these foods can possibly contain parasites that are linked to diseases, which can affect the fetus developmentally. Toxoplasmosis is a disease carried by the parasite Toxoplasma gondii, and it is the most common parasite in humans (1,2). It has been linked to many brain disorders in humans, and even permanent changes in the way a person thinks and acts (1). Scientists have learned that it is hosted in cats and carried through other animals. The parasite can be carried in anything from vegetables
