New Guinea Flatworm Research Paper

Parasites can manipulate hosts in many different ways. In the article “Suicide Grasshoppers Brainwashed by Parasite Worms,” James Owen describes the relationship between parasite hairworms and grasshoppers. These parasitic worms find a host, such as a grasshopper, and enter the body. After entering the host, the worms cause the grasshoppers to commit suicide by jumping into the water. This article explains how parasites cause grasshoppers to commit suicide, how the parasites enter and exit the host, and how scientists use this information to create a better understanding in research about parasitical behaviors.

The Earthworm is a crucial component of the environment due to their interactions with soil which then, in turn, provides benefits to other living organisms such as their burrowing behavior, which allows nutrients, air, and water to delve deeper into the soil. After soil is swallowed by the pharynx, the food matter is sent through the esophagus and into the crop, where the soil is stored until it interacts with the gizzard. The main function of the gizzard to grind the soils so that it can enter the intestine, where gland cells within release fluid to aid in the process. When organic matter is finally excreted from the intestine to the anus through the worm through the process of casting, more nutrients are introduce into the soil that benefit plant life. The earthworm also has a brain located behind its pharynx, called the cerebral ganglia, that is crucial for movement. The

Heartworm disease can be fatal to your furry friend if it is left untreated. Foot-long worms are found living in the heart, lungs, and associated blood vessels. These worms can cause severe damage in organs as well as cause lung disease and heart failure. This disease has been found to affect dogs, cats, ferrets, wolves, coyotes, foxes, and sea lions. Which the information I learned from my research, I will be discussing the history of heartworm, what causes it, the symptoms and clinical signs, how to diagnose it, the treatment need, as well as preventing it.

Another major risk in the jungle would be Schistosomiasis, or “snail fever”. It is a worm disease

As we have seen in the video on the museum, the Guinea Worm Containment Center threat there patient by extracting the worms from their bodies but it seems extremely difficult to extract those worms in which it can take week or even months for the worm to come out. Submersion results in subjective

There is a multitude of reasons as to the threat the screwworms pose. This is the first time in about thirty years that screwworms have come in contact with any animals in the U.S. (Guarino, 2016). Also, due to being tropically adapted, screwworms are well suited for life in Florida given its warm climate (Schultz, 2008). This unpredicted outbreak has instigated concern for the health

Lungworm (also known as the husk), is caused by the worm Dictyocaulus viviparus. Lungworms live in the airways of the lungs and can cause severe respiratory problems and coughing. It can affect both young and adult animals after they have been exposed to infected pastures for grazing. Lungworm mainly affects cattle, but has also been seen in other ruminants, such as sheep, goats and deer. The number of cases in lungworm has risen since the 1990s, mostly due to wet summers.

Once inside the human the worms begin to create nodules within the human’s skin. These nodules are obstructions causing bumps and lacerations beneath the skins surface. As the eggs are released they begin to travel throughout the subcutaneous layer of the host’s skin (Figure 4) causing their immune system to react (Gonzales et al. 2009), this reaction causes the bodily mutilation that is associated with river blindness. The disease may range mild (dermatitis) to severe (visual impairment and blindness).

The guinea worm disease is most common in Africa. There is only about 1,000 US cases per year, but still it’s very rare to obtain in the US. The Guinea Worm Disease is a parasitic infection occurs and thrives off of dirty water. This disease has been terminated from most parts of the world but the most cases occur in parts of Africa. The reason being, in Africa it is not easy to come across clean water, therefore, the guinea worm thrives in Africa.

They promote the activities of those organisms “shedding and increasing the surface area of organic matter and making it more available to small organisms”. The Nightcrawler is consumed by snakes, birds, moles, toads and even sometimes foxes. Other notorious beings known to eat the worm are beetles, slugs, leeches, flatworms, other types of parasitized earthworms.

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 worm’s life cycle starts off with eggs of the worm are laid in human feces, the larvae hatch in 1 to 2 days, then rhabditiform larva comes out of the egg, the rhabditiform will molt twice in 10 days to form the filariform larva, it will then enter another body of a living being through its skin in their foot, it will travel up to the lungs through the circulatory system, the worm will travel to the intestine, in the intestines it molts into an adult worm, then it will attach to the inner walls, mating occurs if another worm is present, and the eggs will pass through the body in feces again.

The first animal in the world who could search and destroy was an ancient ancestor of the flatworm, which probably appeared about 560 million years ago. A slender, cylinder-shaped animal that was devoid of appendages and bilaterally symmetrical, with a defined head and tail, centralized nervous system (i.e., brain, nerve cords), stereo sense organs (i.e., eyes, nose ears), a mouth and cilia (for locomotion).

Dracunculiasis the disease commonly known as Guinea Worm is caused by the parasitic worm Dracunculus Medinensis . Guinea Worm disease only occurs in 10% of the world’s poorest populations who has no access to safe drinking water or health care (CDC) . This parasitic worm is the largest of parasites affecting the human’s tissues. The risk for Dracunculiasis varies by ones sex, age, profession, and ethnicity. These differences reflect from how people’s drinking water is obtained in these countries (Medscape). Drancunculiasis is commonly found now in Southern Sudan. About the same number of men and women are equally infected. Guinea Worm is common among the ages of 15–45 years old. People in this age group are known to be farmers, herders,

Guinea worm has long been documented in Nigeria, yet despite the long term presence, there had been little effort to quantify the burden or to prevent the disease until the inception of the Nigerian Guinea Worm Eradication Program (NIGEP).6 NIGEP was developed with the goal of eliminating guinea worm cases in Nigeria. However, this program also aimed to better understand the full burden and distribution of the disease in Nigeria and to define a framework to begin to initiate prevention measures for the disease.6
