INTRODUCTION
THE WORD HELMINTH HAS ITS ORIGIN FROM GREEK MEANING WORMS. HELMINTHS ARE PARASITIC WORMS THAT HAVE BEEN WITH MANKIND SINCE TIME IN MEMORIAL. THE DISEASE BURDEN OF HELMINTH INFECTION ESPECIALLY TO DEVELOPING COUNTRIES FAR OUT WEIGHTS COMMONLY KNOWN INFECTION SUCH AS TUBERCULOSIS. EGGS OF INTESTINAL WORMS CAN BE SEEN IN FEACES OF MUMMIFIED BODIES WHO DIED THOUSANDS OF YEARS AGO.
DISCUSSION
GLOBALLY ASCARIASIS (ROUNDWORM) INFECTION IS THE MOST PREVALENT ABOUT 807 MILLION AND COMMONEST IN ASIA, SUBSAHARAN AFRICA AND SOUTH AMERICA. THIS IS FOLLOWED BY TRICHURIASIS (WHIPWORM) AT 604 MILLION AND THEN THE NECATOR AMERICANUS (HOOKWORM) AT 576 MILLION. THE ABOVE INFESTATIONS ARE COMMONEST IN AFRICA, ASIA AND SOUTH AMERICA.
FILARIAL NEMATODES (WUCHERERIABANCROFTR, BRUGIA MALAYI) ARE ALSO A COMMON PREVALENCE IN INDIA AND PARTS OF SUB SAHARAN AFRICA INFECTING ABOUT 120 MILLION PEOPLE. OTHER RELEVANT HELMINTH INFECTIONS INCLUDES SCHISTOSOMIASIS (SCHISTOSOMA HEMATOBIUM, SCHISTOSOMA MANSONI AND SCHISTOSOMA JAPONICUM) COMBINELY INFECTING ABOUT 207 MILLION PEOPLE MAINLY IN SUBSAHARAN AFRICA, EASTERN BRAZIL, CHINA AND SOUTH EAST ASIA.
FOOD BORNE TREMATODIASIS SUCH AS CLONORCHIS SINENSIS, OPISTHORCHIS VIVERINNI (LIVER FLUKE), PARAGONIMUS (LUNG FLUKE) AND INTESTINAL FLUKE SUCH AS FASCIOLOPSIS BUSKI AND FASCIOLA HEPATICA COMBINELY CAUSE ABOUT 40 MILLION INFECTIONS MOSTLY IN DEVELOPING PARTS OF ASIA. TINEA SOLIUM WHICH IS A PORK TAPEWORM CAUSES 400000 INFECTIONS IN AFRICA ASIA AND SOUTH AMERICA.

- The Disease Of Guinea Wormexplanatory essayThis disgusting worm parasite is spread by flies and mosquitoes. The adult worm spreads its larvae throughout the host’s lymphatic system and causes the lymph nodes to become clogged up. This also makes the tissue in the host’s body to swell up and create massive muscle deformations, otherwise known as elephantiasis. The elephantiasis mainly affects the legs and genitals. The disease also affects the eyes but that can be easily detected through close inspection but it commonly causes river blindness in the host. It’s been estimated that the parasite is one of the leading causes of blindness throughout the world.

There are three major species of tapeworms: taenia saginata (beef tapeworm), taenia solium (pork tapeworm) and diphyllobothriasis (fish tapeworm). All these species of tapeworms are acquired by humans in consumption of raw, undercooked or smoke contaminated meat or fish (John, 2006). Tapeworms are considered humanity’s largest intestinal inhabitant. They each have a scolex or head, that attaches to the intestinal wall. As long as the head remains attached to the intestinal mucosa, a new worm can grow from it. Tapeworms do not contain a digestive tract, so their nourishment comes from absorbing partially digested substances from the host. They are whitish in color, flat and ribbon like, with a covering that resembles a transparent skin like layer (Turkington,2007). It’s prevalent among underdeveloped countries where sanitation is poor and among people who regularly consume raw, unwashed or undercooked beef, pork or fish containing the cyst eggs of various tapeworms (John, 2006). But in the United States, laws governing feeding practices and inspection of domestic food animals have largely eliminated the problem of tapeworm, but an estimated 1,000 new cases are diagnosed in the United States each year (askville, 2013). There are two specific parasites that I will be discussing. One being the adult tapeworm that inhabits the small intestine and cysticercosis which is the most common parasitic disease of the central nervous system, also called neurocysticercosis.

Onchocerciasis, commonly known as “river blindness” is caused by the parasitic worm Onchocerca volvulus it is transmitted to humans by a bite from infected black flies. Worm larvae that are transmitted develop into adults and settle into the fibrous nodules on the human body and produce microfilariae. Prolonged infection to the parasitic worm can lead to blindness and depigmentation of the skin. Onchocerciasis mostly affects the south-western region of Ethiopia, Africa and the Americas (World heath orginisation, 2006) and the
In this essay, the author
- Explains that onchocerciasis is a disease of public health and socio-economic importance in ethiopia.

This is the approximate time when pigs were first domesticated in that region. This implies that the species Trichinella spiralis was introduced to the Americas from pigs. However, there is evidence that the early people of this world, hominid hunters, have consumed foodborne parasites by hunting wild game from millions of years before. Today, swine is governed on the ensuing transmission, and evolutionary diversification.

Parasites living outside the body are called ectoparasites and living inside the body is called endoparasites. Endoparasites can be devided into intercellular and intracellular. Intercellular parasites live in tissues and organs outside the cells while intracellular parasites are smaller one and reside in the cells such as babesia, plasmodium, etc. However, these protozoans need to come out of the cell to invade other cells and to complete their life cycles. Most of the parasites can not complete all life cycle in a single host. They need one more host to complete their life cycles.

839 wordsRead More - Parasites and Horsescomparative essayParasites are organisms that live in or on another organism, and benefit at the expense of the host (Burns). They are considered a cause of clinical disease in horses as well as other animals. Horses become infected with parasites mainly through consumption of grasses. Some of the harmful affects include burrowing through arteries and intestines, weight loss, and colic. Colic is a general term for any gastrointestinal problem. The magnitude of the effects does however vary due to the fact that there are many different types of parasites. Up until the 1960’s there was no way to treat any of them. The creation of Benzimidazole anthelmintics in the 1960’s dramatically altered the control of parasites. Later in the 1970’s and 1980’s two new forms of this drug were created. These medications are also known as dewormers and work by poisoning parasites that reside in the horses (James). The majori...

Several protozoan species in the genus, Entamoeba, colonize humans, but not all of them are associated with the disease. E. histolytica is well recognized as a pathogenic ameba, associated with intestinal and extra intestinal infections. E. histolytica goes through two life cycles: A cyst which can survive harsh conditions, such as the human stomach and the small intestine; the cyst form transmits the disease. The trophozoite which deals with the infection of the host by invading the epithelial cells. Occasionally trophozoites might be transmitted during sexual intercourse. ctual infection of the host by invading the host epitheliurviving in harsh environments as well as in the tA trophozoite is an active form or feeding form of a protozoan, especially a parasite, as opposed to the resting or reproductive form. Trophozoites migrate to the large intestine where live and multiply through binary fission. E.histlytica lives and multiplies in the human body as a trophozoite. A trophozoite is an active form or feeding form of a protozoan, especially a parasite, as opposed to the resting or reproductive form. Trophozoites migrate to the large intestine where live and multiply through binary fission.
