Toxoplasma is a parasite that can affect a person’s mental abilities‚ memory‚ and can cloud decision making abilities. This parasite can affect fetus’ in detrimental ways during pregnancy‚ caused by cat’s feces in litter boxes. Animals that live off the land end up ingesting cat feces that will live in their brain until it spreads to what is supposed to be fresh vegetables‚ meat‚ and water. Once the parasites make contact with the food‚ it is not long before contact is made with a human. When medicine

Parasitic Disease: Malaria Malaria is a serious parasitic infection that is spread by Anopheles mosquitoes. The Plasmodium parasite that can cause malaria is neither a bacterium nor a virus therefore it is a single-celled parasite that multiplies in red blood cells of humans as well as in the mosquito intestine. C. Laveran in 1880 was the first to identify the parasites in human blood. In 1889 R. Ross discovered that mosquitoes transmitted malaria. Malaria is a serious global problem and there

painful infection of the lymphatic system. It is caused when thread-like filarial parasites are transmitted to humans through mosquitoes. There are three forms of the parasites which are Wuchereria bancrofti‚ Brugia malayi and Brugia timorican. The most common is Wuchereia bancrofti. When the mosquito bites the human‚ it injects the larvae into the blood stream which then circulates into the lymphatic system. The parasites can live up to six years in a human. The disease is most common in tropical areas

parasitic worm that lives in rats. It is also called the rat lungworm. Baby parasites (larvae) pass through rat feces into soil and may be picked up by snails or slugs. You can be infected if you live in or have traveled to areas where the parasite is common. These areas include parts of Asia‚ the Pacific Islands‚ the Caribbean‚ and Africa. The infection does not pass from person to person. If you get infected with the parasite‚ you can develop a type of brain inflammation called eosinophilic meningitis

intestinalis. Other names for this parasite are Giardia lamblia‚ and Giardia duodenalis. There are many different genetic assemblages of this parasite‚ some that infect only mammals‚ some that infect primarily humans‚ and a few that will affect both animals and man. [1] Transmission: While G. intestinalis “can live in the intestines of animals and people” it is very rare for a human to acquire such an infection from their cat or dog.

The people at significant risk for malaria include those who have little or no immunity to the parasite. Children‚ pregnant women and travelers are most likely to fall victim to the disease.

PELLAGRA Pellagra was a disease that affected hundreds of thousands of residents within the southeastern region of the United States from the time of its first known reports in the early 1900 ’s to the end of World War II‚ in 1945. Dr. Joseph Goldberger‚ from New York‚ was given credit for finding the cure for Pellagra. Contributing to the Goldberger ’s cure were the discoveries of doctors and scientists prior to and during the time that Dr. Goldberger was working on the cure himself. Pellagra

The malaria parasite metabolizes food and produces carbon dioxide as a waste product. This carbon dioxide‚ when in an an environment like that inside a red blood cell‚ forms carbonic acid. Because of these high levels of C02 and acid‚ the hemoglobin in a parasitized red blood cell tends to be in the deoxygenated form. If a red blood cell contains S hemoglobin and a malarial parasite‚ the S hemoglobin will be deoxygenated‚ aggregate‚ and sickle the

(WHO). They further estimated that‚ in 2002‚ 2.2 billion people were exposed to infection by the Parasite Plasmodium and more than 1 million deaths are recorded annually (World Health Organization‚ Para 5). Malaria is caused by apicomplexan parasites of the genus Plasmodium. Charles Louis Alponse Lavern‚ who was a French army surgeon stationed in Algeria‚ Africa‚ was the first to notice the parasites in the blood of a patient suffering from malaria. The four species that infect humans are Plasmodium
