Taenia solium, also known as the pork tapeworm, is a parasitic tapeworm that has infected millions of people, mostly those from countries that eat large amounts of raw meat like Europe and Asia, but can also be found in Canada, the United States, Argentina and Uruguay. These tapeworms fall under the kingdom: Animalia, phylum: Platyhelminthes, class: Cestoda, order: Cyclophyllidea, family: Taeniidae, genus: Taenia, species: solium. Taenia Solium are flat, segmented parasites that can grow from 2 to 7 meters (6.6 to 22.9 feet) in length, with about 800 segments called proglottids and are normally white in color. The adult tapeworm is divided into three parts: scolex, neck, and strobila. The scolex is the head of the tapeworm, positioned at the end of the organism. The scolex acts as an attachment device with four suckers, hooks and rostellum, a knob-like protrusion, used to attach itself to the intestine of the host. The neck is an elongated region between the scolex and the stroblia. The stroblia contains most of the systems of the tapeworm and is made up of the proglottids. The pork tapeworm does not have a digestive system, but is composed of four systems: tegument, nervous, osmoregulatory and muscular.
The life cycle of the tapeworm starts with a pig, an intermediate host, that eats vegetation that is infected with tapeworm eggs. Eggs can survive for 8 months; however, environmental conditions usually do not let the eggs survive to the next stage in the life cycle. The
When the Larvae are ingested by a human they turn into adult tapeworms and live in the intestines of humans, this is called an intestinal infection. They can live for up to 30- years in there host
But, these small intermediate hosts can be eaten by larger predators such as; trout, perch, and pike. By this happening the sparganum can go to the musculature of the larger predator, which can be fish and mammals. Then the human can catch the diphyllobothariasis disease by eating the infected host fish raw or undercooked. After ingestion of the infected fish, the plerocercoids develop into immature adults and then into mature adult. The adult worms can reach more than 10 meters long. Several of tapeworms regularly detach from the main body of the worm (that’s where they get their name tapeworm from).They then release immature eggs in fresh water to start the cycle all over again. A tapeworm can live up to 20
Just last month, a deadly worm was found in not one, but four locations in the U.S. state of Florida. This worm, until recently, was documented in only twenty-one countries, most of which were island nations. Although the New Guinea Flatworm may seem as a highly dangerous predator, it is only about two inches in length and mainly targets snails for its nutrition. These worms are not harmful to humans, but they will feast on any soft creature in the soil. In order to eat snails or any critters with a hard shell, the New Guinea Flatworm latches itself onto the shell’s opening and then spits out its own stomach through the opening in its belly. This allows an acidic goo to dissolve the snail’s flesh and the worm can continue on with its meal by swallowing both its stomach and the snail.
This worm has other things it can eat as well. The one thing this worm loves to eat is the snail eggs it finds when it attaches itself to the bottom of the cabbage leaves and when it is searching for it's prey as well. Many scientists have said that the new guinea flatworm is one of the fifteen tenth largest dangerous and threatening invasion on the united states. They say it continues to grow even this year as well. It fact many people say that when it starts to develop the worms never stop growing and developing and continue to grow and grow and take over populations and specific areas in the united states. Many relationships with other species in the worm occur because the worm continues to invade state by state ,county by county or even area by area and it is causing problems everywhere. Another reason the specific species relationships happen is because the worms continue to have offspring and then they will continue to develop and develop. The next reason is the flatworm can carry a parasitic disease that infects rats and can be passed on to
Earthworm: In our dissection of the earth worm we found they belong to a group of animals called annelids. Its body is segmented into several parts, except for the head and tail regions. Its diet is of decomposed plants and other small particles in the
For the farmers of south east QLD (Australia), Barbers Pole worm is the main worm internal parasite infecting their sheep. This is due the amount of rain and the summer heat. Due to the weather and the climate of south east QLD, makes it the perfect environment for the Barbers Pole worm to infect the sheep. The Barbers pole life cycle is as so, once the barbers pole worm has laid its eggs in the stomach of the sheep, (barbers pole worm can lay up to 10,000 eggs per day), the worm eggs move through the digestive track and are mixed in this the fesses, the fesses are pooped out and into the land, the eggs hatch within 4-10 days, they will hatch faster in hot climate and slower in cold. Once the eggs have hatched they begin to feed on the bacteria
The mealworm is the larva of the mealworm beetle which is a specie of darkling beetle (Animals.mom.me, 2016). The darkling beetle has a metamorphic life cycle that begins with an egg hatching into a small mealworm over a four week period (Sandhyarani, 2016). The second life stage of a darkling beetle is the larva stage where the egg will hatch into a small brown mealworm that eats and grows for about eight to ten weeks till its next stage as a darkling beetle pupa (Sandhyarani, 2016). The larva stage of a darkling beetle is the stage in which the mealworms will be investigated. The mealworm will then enter the pupa stage during one of its shell sheds causing the mealworm to
Nematodes, also known as roundworms due to their round cross-section, are parasites that can affect both domesticated and wild animals (Bassert and Thomas 451). The roundworms that are common in dogs are Ancylostoma caninum, Toxocara canis, and Trichuris vulpis (Bassert and Thomas 451). The roundworms that are common in cats are Ancylostoma tubaeforme, Dirofilaria immitis, and Toxocara cati (Bassert and Thomas 451). Dirofilaria immitis and Toxascaris leonina can affect both dogs and cats (Bassert and Thomas 451). Baylisascaris procyonis can affect both raccoons and dogs (Bassert and Thomas 454). Roundworms can live in many of the organs and systems of the body, such as the eye, gastrointestinal tract, urogenital system, circulatory system,
•Spread hydatid tapeworm – hydatid tapeworm are a risk to human health and cause livestock production
There are approximately 800 million people that have acquired whipworm infections. Whipworm infections not only occur in humans, but can also occur in animals such as dogs and cats. Contamination with the whipworm usually accidentally occurs as a result of touching the contaminated dirt and then touching the hands to the mouth. Contamination might also occur by not properly washing vegetables or fruits before consumption. After ingestion of the whipworm eggs, the eggs typically travel to the small intestines via the gastrointestinal tract. In the small intestines the eggs then hatch and the larvae grow to maturity. The adult worm them developes in the large intestines. The female worms that are present in the large intestines can begin to transfer eggs into the intestines within two months. Female worms can produce from approximately three thousand to twenty thousand eggs in a twenty four hour
Earthworm samples were collected from the moist soil at Wilcuts trail by Hess Creek within a 152 meter area. Due to the isolation of this environment, there were an abundant amount of undisturbed soil with many earthworms that could be collected as test subjects. Several holes were dug to be 1-3 cm deep with a shovel, the soil was hand sifted to find the earthworm subjects. More than 60 adult earthworm samples were collected within six 40 ounce plastic containers. Each earthworm was checked for a clitellum band around their body which indicates the worm is adult. Each plastic container was filled with 30 ounces of soil that was weighed out via a portable scale. The worms were stored in the soil in which they were found so that they
Four stages of this parasite have been identified the first stage is the penetration phase which is day 1-17 during this stage the larvae moves into the body of the animal and moves to the lungs. The second stage which is the prepatent phase which is day 8-25
In order to follow this diet, a person must eat a tapeworm that has a parasite. A person can get a tapeworm parasite by eating raw meat or consuming a tablet that has a parasite. People who live in a country where the tapeworm diet is legal can get beef tapeworm cysts to eat. It is important to make sure that the tapeworm
Mode of infection: A mode of infection for Hydatid Cysts is the ingestion of eggs. If a person ingests food or drinks water that is contaminated with feces from a person or animal with tapeworm, a microscopic tapeworm eggs can be ingested. If an animal has a tapeworm infection, it contains larvae cysts in its muscle or tissue, therefore eating undercooked meat can have you ingest the larvae. The larvae will then develop into adult tapeworms in the intestines.
The Lumbricus species of the earthworm is found in many different places over the world. The terrestris worms are native to the regions of Europe. This species was not known to be in the parts of North America, until farmers started to move into the area. Today earthworms are native to all parts of America. (Nuttinen et al 2014).
