Taenia Solium Worm Essay

In part 2 of the experiment we are inducing RNAi through the process of feeding. To do so, a black pen is used to label the bottom of an OP50 seeded plate with the date and “wild type”. Another OP50 seeded plate is labeled with the date and “dpy-13”. A black pen is then used to label the bottom of the plate seeded with dpy-13 RNAi feeding strain with the date and “wild type”. Five L4-stage worms from the plate of wild type worms are then picked and moved to the OP50 seeded plate labeled “wild type”. Any eggs or young larvae that may have been accidentally transferred are to be picked off of the plate and then flamed in a Bunsen burner. The same method is used to move five L4 wild type worms to the plate seeded with the dpy-13 RNAi feeding strain, and once again to move five L4 dpy-13 worms to the OP50 seeded plate labeled “dpy-13”. These plates are then incubated upside down at 20˚C.

Imagine feeling disappointed from what seemed to be an extremely suspenseful story, but turned out to be exactly what was expected, all because it was written in the point of view of the wrong character. Stephen King’s thriller, “The Raft” begins with a group of young college kids returning to their old swimming lake in the fall. They each swim to the raft and the quietest of the group, Randy, quickly realizes the object in the water isn’t as harmless as it looks. When the thought-to-be “oil slick” begins to kill off his friends, Randy’s mind races, trying to find solutions to his predicament. King allows readers to travel through the bizarre, yet frightening encounter through the perspective of an outside narrator who is also able to be inside of Randy’s

Executive Summary - Coors’ prominence in the beer industry has always been overshadowed by its bigger competitors like Budweiser, Miller and Molson, but new insights unearthed by this report may pave new roads for a more exciting future. The first part of our analysis describes the typical Coors drinker as an aged 25 to 44 male light beer drinker consuming almost seven bottles a week. He also works in a managerial or professional occupation earning over $30,000 annually. Coors’ three competitors also exhibit a similar consumer base with the exception of Molson being predominantly regular beer consumers. These conclusions are tested to be statistically significant.

Gut worms are a type of roundworm that infect cattle in their stomach by causing eggs to form in their feces. Also known as Parasitic Gastroenteritis (PGE), this disease causes the cattle industry to lose millions of dollars each year.

Nine months after the female worm mates it begins producing the eggs that will be digested by the vector and continue the cycle.

An incision was made below the clitellum at around segment 40. The worm was cut on one side of the dorsal blood vessel, starting at the clitellum down to the anus with small scissors. A thin, shiny cuticle began to peel from the worm’s skin. A few times, the intestine was slightly cut and runny, dark brown soil began to seep out. After this, the worm’s clitellum (segments 30 to 38) was cut through to the mouth (segement 1) The worm’s skin was pinned down to the tray,

Who/what are hosts of your worm/disease? The hosts of my worm/disease are ducks. Nassarius obsoletus and snails are the transitional hosts for this species.

Cercariae enter the body through unbroken skin and it passes through the lining of the mouth or gastrointestinal track. When in the body the worm penetrates the nearest vein to travel to the liver, where they grew and mature. When they mature in the liver, they pair up male and female to travel to the intestines and or bladder to lay eyes. A high content of eggs in tissues causes severe problems for the individuals with the condition. The disease mostly affects the liver and the spleen, it causes both of these organs to swell or in other words it causes enlargement. It makes sense for the liver and spleen to swell, considering that the worms stay and mature in the liver. Katayama is a symptom associated with the disease; the signs and symptoms are fever, feeling tire, and bronchospasm (Sherwood, 2012). There are two types of schistomosomiasis, the intestinal and urinary track. Large amount of worm eggs in the intestinal wall cause immune respond which led to

Their symptoms will consist of bloody diarrhea, nausea, weight loss and abdominal pain. It is transferred the same way as it is in digs; by fecal matter. They mostly occur in children due to hands in mouth and so forth. Also in mainly hot humid areas with very low sanitation anywhere.

The common name of the Paragonimus Westermani is called the lung fluke. The Paragonimus worm tends to look like a coffee bean. It is short and thick, looking like a reddish brown color. Their oral and ventral suckers are visible, they have scale like spine that are evenly spaced out. The eggs from the worm are laid from a human's lungs through the motion of the microvilli. They are then put in the gastrointestinal tract and out the body. If a human was to ever eat something raw of any sort it then the forming cyst or larva that was in that animal creature migrates into the human's stomach. The cyst later goes through the intestines, diaphragm, lungs, etc. and becomes an adult. The male and female lung worms reproduce more and the cycle starts

First of all, the worm is still greatly adapted to the environment. Worms like darkness so they live underground. The worms´ structure was adapted to move in narrow tunnels. They eat leaves and other decomposed things at night. Also, worms have setae which help

Ascariasis is found in over one billion people worldwide. This type of roundworm can be transmitted into the body if the person gets them on his or her hands then transfers them to their mouth. They are usually found in soil. In countries where people live in poverty the roundworm has a very high chance of being transferred to people. The reason for this is because in some counties people use human feces to fertilize their crops, and they many have poor disposal for their feces. Once someone ingests a ascariasis roundworm it can be transmitted from person to person very fast through infected feces that is not disposed properly. Children are more likely to be infected because they put their hands in their mouth a lot and that can transmit roundworms into the body very fast. Children also are more likely to have symptoms because their intestines are smaller and the worms have less room. Once a child swallows a roundworm egg it passes down into their intestine where it will then hatch into a baby worm called larva. The Larva can pass through the intestine wall into the bloodstream where it will then travel though the lungs up to the throat. They are then swallowed again and go into the small intestine where they grow into adult

Trichinosis is a rare infection caused by a parasitic worm. People can become infected by eating the raw or undercooked meat of an animal infected with this worm. Bear meat and pig meat are possible sources of this infection. The severity of the illness will vary depending on the number of worms in the contaminated meat that is eaten.

The larvae will simply undergo a dormant stage within an intermediate host until they are in a dog again. The development of the larva into worm is restricted to the gastrointestinal tract of a dog. If the parasite finds itself inside a human through ingestion of the infective eggs, it does not exactly have a sense of direction. That’s right if a person eats egg-infested poop, once the eggs hatch the larva or worms will meander wherever they feel like going. That means if they want to take a trip through the bloodstream and capillaries, lungs, or if they want to harbor in the brain, liver or eye they can. The most common infestation in the human body leaves mild symptoms, but once in the eye the effects can be local inflammation partial blindness or complete blindness. Nerve endings can become damaged if tampered

The nervous system consists of a ventral nerve cord, with one ganglion in each segment, and nerve ring surrounding the pharynx. Smaller ganglia are also located in the lateral and dorsal portions of each segment, but do not form distinct cords.
