Intestinal parasite Essays

In the article, They might sound gross, but intestinal worms can actually be good for you, Dr. William Parker, an associate professor of surgery at Duke University, provides an in-depth analysis on the benefits of helminths, or worms. Dr. Parker argues that helminths are actually quite beneficial as opposed to what people may think based on the connotation of the word parasite. He strives to persuade the audience that the helminths supply a valuable symbiosis within its host. Dr. Parker utilizes

There are three types of parasites that generally infect people. One species of parasites are the anisakid roundworm, they affect people mainly through sea food. Parasites are not a concern in well cooked fish. The three types of parasites that may affect humans are tapeworms, roundworms (nematodes), and protozoa. Some parasites remain in the intestines, others travel through the intestines to obtrude upon other organs. Tapeworms and roundworms grow in host’s body and lay their eggs there; the eggs

Malaria Overview- Malaria is an existence debilitating blood disease created by parasites transmitted to people through the nibble of the Anopheles mosquito. Once an infected mosquito nibbles a human and transmits the parasites, those parasites duplicate in the host's liver before contaminating and obliterating red platelets. The disorder can be controlled and treated if analysed right off the bat. Lamentably, this is impractical in a few zones of the world ailing in therapeutic offices, where jungle

“first-world” countries are not immune to parasites. In fact, parasitic infections are more common than most people think. You may even have parasites living in your intestines right now. And, when undiagnosed, they could live, feast and digest inside you for years, leaving you feeling ill most of the time. But here’s the good news — there are remedies that eliminate parasites. Here’s how to get rid of parasites naturally. What exactly is a parasite? Parasites are organisms that live off other organisms

Important tapeworm parasites of humans Zainab Waseem Tapeworms are the parasites in the gut of vertebrates or in derivatives of the gut, as in bile ducts of the liver or in intestinal caeca of birds. Although most species of cestods or tapeworms parasitize wild animals but few of infect humans and animals, therefore they are of specific interest. All the tapeworms that parasitize and infect humans belong to the orders of Pseudophyllidea and Cyclophyllidea. Tapeworm infection Tapeworm infection

Cryptosporidiosis is a form of gastroenteritis that is caused by the parasite Cryptosporidium. Once the parasites are taken in by mouth, Cryptosporidiosis can occur. [1] Outbreaks of cryptosporidiosis have been linked with public swimming pools and contaminated water supplies. Cryptosporidium is a type of protozoa, and infects humans through ingestion of their cysts on hands, water or foods that have been contaminated with faecal matter. Once in the human body the cysts are activated by the acid

Giardiasis is a global disease. It infects nearly 2% of the adults and 6% to 8% of children in developed countries worldwide. Nearly 33% of people in developing countries have had giardiasis. In the United States, Giardia infection is the most common intestinal parasitic disease affecting humans (Kappus et.al., 1994). Between 2006-2008 in the United States, known cases of giardiasis were twice as high between June to October as they were between January to March (CDC, 2010). Anyone can be infected by

(flatworms) which are widely reported with mixed infection also common (Permin et al., 1997; Poulsen, 2000). Nematodes or roundworms are the most important group of helminth parasites of poultry, worms are elongated, cylindrical and unsegmented, and most roundworms affect the gastrointestinal tract (GI tract), with an occasional parasite affecting the trachea or eye. Round worms are directely life cycle, and it is particularly short 21 days. The most prevalent helminth species in chicken are Ascaridia galli

Author and known Professor of Surgery at Duke University, Dr William Parker has made an argument in his article “.... But Intestinal Worms can be good for you, ” he establishes his argument of why worms can help people in a medical sense by appealing to the audience by using modes of persuasion, colloquial language and rhetorical questions, and positive connotations and repetition, as well as author's purpose. To begin with, Parker utilizes modes of persuasion by appealing to the audience with

tapeworm eggs, which can then hatch, and the larvae migrate to various tissues of your body including your brain. When the larvae form cysts in the central nervous system, the infection is then referred to as neurocysticercosis (1). Having these parasites in your brain can cause many neurological issues such as intracranial hypertension and epilepsy. In fact, neurocysticercosis is one of the major causes of adult-onset epilepsy (2). While seizures and headaches are the most common symptoms, lack of

stercoralis is a human pathogenic intestinal parasite roundworm disease with free living and autoinfective cycles. The Infection is acquired through direct penetration of human skin by infective larvae when in contact with contamination soil and recreational activities. Strongyloides is often asymptomatic in a healthy host with mild gastrointestinal symptoms. But if the host becomes immunocompromised may involving more than one organs and increase the intestinal worm encumbrance and lead to strongyloidiasis

West Africa (Despommier et al., 1995). 3.1. Historical Background In 1852, Theodor Bilharz (figure 1) a German physician working at Medical School of Cairo, noticed a flat worm in the porto-mesenteric veins of post-mortem Egyptian boy . He named the parasite “Distomum haematobium”. Figure 1: Theodor Maximillian Bilharz (1825-1862) In 1856, Meckel Von Helmsback named it Bilharzia rather than Distomum, as the

is caused by the parasite Trypansoma cruzi. Triatomine bugs, a type of reduviid bug or “Kissing Bug”, carry the parasite. Most commonly, a person is infected at night when the triatomine bug takes a blood meal near the lips. The bite, however, is not the cause of the infection. While the bug is feeding, feces are dropped near the bite wound. The parasite, T. cruzi, then enters the body. It then multiplies within the cells of the body until the cells burst and release the parasites into the blood stream

these symptoms later on in life. As puppies, they will arrive at pet stores, or in homes, with Giardia (a parasite that causes diarrhea), Parvovirus (A highly contagious viral disease that is life threatening), distemper (A viral disease in dogs that causes a fever and coughing), upper respiratory infections, Pneumonia. Mange (parasitic mites on a dog’s skin), fleas, ticks, intestinal parasites, heartworm, and chronic diarrhea. Furthermore, puppies only have about six weeks to accommodate to their

lungworms in Europe (cold and rainy), rather than in North America. The parasites thrive in the winter months and as the year goes on and the temperature rises, the parasite numbers and productivity drop dramatically. The lifecycle of lungworms is very meticulous. The general life cycle of a lungworm begins with an ingestion of infective larva/e. Once the infective larvae are consumed by grazing cattle they penetrate the intestinal wall and migrate through lymphatics and blood vessels, reaching the

their vet's advice about the Lyme disease vaccination. It is also suggested that you consult your vet to show you the proper way to remove ticks from your dog (it is not a good idea to try to do it yourself). Heart worm Disease Heart worms are parasites transmitted by mosquitoes and can potentially be fatal to your dog. Have your dog tested for heart worms by your vet and ask about recommendations for heart worm preventatives which are often easy and inexpensive to provide. The fact that your dog

Colic in Horses Colic in its truest definition means abdominal pain. Overtime, the term has evolved to describe a condition rather than clinical signs. Colic includes all forms of gastrointestinal conditions that cause pain as well as other conditions that do not involve the gastrointestinal tract. Colic is the major cause of morbidity and mortality in horses. According to a survey in 1986, from the Morris Animal Foundation, colic is the number one health concern and a leading cause of premature

toxin is an protein complex which is made up by six subunits, one A subunit and five B subunits. The A subunit is the enzymatic subunit and the B subunit is the binding subunit [9]. The cholera toxin is released from the bacteria and once in the intestinal lumen it adheres to the apical surface of the epithelial cell. The B subunit of the toxin binds to a ganglioside receptor, GM1 on the apical surface of the epithelial cell. This triggers endocytosis of the toxin to enable the enzymatic subunit A1

Ascaris lumbricoides, or also known as the "giant roundworm" is a very common intestinal parasitic in humans. Adults worms and larvaes usually live in the small intestine and they are able to cause bowel disease. This "giant roundworm" lives in the intestine and their egg travel through feces of humans who are infected. The average size of adulthood is about 15-35 centimeters in length. It is interesting that if a person defecates in some place that is not the toilet, for example, near a tree, a

INTRODUCTION Epidemiology Soil-transmitted helminth infections are gotten through contact with soil contaminated with infected feces. STH infections were once common throughout the world, including the United States, and some occurrence are still seen in the U.S. each year. With proper sanitation, these infections are now common only in poorer countries. More than four billion people are at high risk throughout the world, with over one billion individuals already infected. The greatest numbers
