Cestodiasis, otherwise known as “cestodes” or “tapeworm infestation”, is an infection caused by consuming tapeworm eggs and/or larvae. This is a rare disease found in humans with fewer than 200,000 US cases per year. This rare disease is treatable by a medical professional but requires a medical diagnosis. Cestodiasis or “cestodes” can be spread through contaminated food or water. A tapeworm infestation in the human body is usually confined to the intestine but can be spread to other parts of the body. If the tapeworms reach other parts of the body it can cause organ failure and tissue damage. Adult tapeworms can live up to 30 years in their host. Many people never realize they have tapeworms because it doesn't have any symptoms. In many …show more content…
It is a class of the parasitic worm called the flatworm. It is known best as the tapeworm. Depending on the tapeworm, they can become very long. The tip of their scolex contain hooks and suckers to help better attach itself to its host. It will attach itself to the intestinal wall then suck and absorb their food through the skin. There are 2 types of tapeworm infestations in humans. The first one is called intestinal cestodiasis which is where mature worms live in the lumen of the intestine, producing eggs which are then placed in feces. They are then in the future passed into other hosts and then developed there. The second type of infestation is visceral and somatic cestodiasis which is where the larvae form and live in the bodies organs. There are 30 or more types of tapeworms that can cause intestinal cestodiasis in …show more content…
This worm can grow up to 4.5 to 6 meters long which is about 15 to 20 feet long. Another type of worm is the Taenia Solium or the “pork tapeworm”. This worm is smaller the the Taenia Saginata only growing 2 to 3 meters long. Diphyllobothrium Latum, or “fish tapeworm”, can grow to 9 meters long. This worm is acquired by eating undercooked meats such as beef, pork, or fish that are usually infected with tapeworm larvae or eggs. The most common tapeworm found in humans is the Hymenolepis Nana or the “dwarf tapeworm”. This worm is no more than a few centimeters long and it releases eggs that require no intermediate
The Meningeal Worm Infestation of up to 20 meningeal worms has been discovered in a single deer’s subdural cavity. The white tail deer are the preferred host, but they rarely ever suffer from any sick or neurological problems from this type of worm. We will see severe signs in llamas and alpacas; these are the two animals that can become infected with it frequently. The meningeal worm can cause damage to the central nervous system and could result in death, so it is important to try and catch it early and learn about how to prevent this deadly worm. Things that you should be familiar with about the meningeal worm are its life cycle, the signs in your animal, and any prevention or treatment options.
On an endless road of meadows and half collapsed barns exists a quaint town living its motto “The City of Progress”. Enterprise, Alabama is stuck between miles of bleak pastures and feeding cows, but the peanut factory overwhelms your every breath. The monotonous drive does have a reward, and it can only be found hiding in a valley of small stores and baptist churches on downtown’s main street. It is a statue that reminisces this town’s story of triumph over its struggling economy during the decline of cotton. Sculpted from stone, a woman is presenting a boll weevil in honor for its efforts in destroying the crop, cotton, Enterprise, Alabama’s main economic source.
The outer tentacles probe for a potential meal, then the inner sensors decide if the prey is edible. They are covered in thick, blackish-brown, water-repellent fur, and have large scaled feet and a long, thick tail. This animal is by far one of the most interesting animals in the world, despite looking like a cross between a rat and an octopus. The way it behaves and utilizes its star nose is fascinating and makes it very unique when compared to other animals.
Oftentimes, people can recall at least one song they know that is undoubtedly catchy because of its repetitive nature. That song can become a nuisance, when it will not leave your mind. When a melody gets stuck in your head, sometimes it could take a whole day to forget the tune. A certain tune can be stuck in your brain for many years! In Oliver Sacks’ passage, “Brainworms, Sticky Music, and Catchy Tunes”, he talks about “earworms”, or a pathological repetition. Sacks uses patterns of development to inform the modern reader about the dark side of music.
the definition of parasite, is something that hurts. for ever. this parasite, was a landmine. I had good medical attention. But once i returned home, I finally left. I wanted to leave. there were rockets, raining down in every place i looked. those rockets stole my family. we couldn't stay. so we fled. the last time i had a true education, was when i entered high school. between 2nd grade and 9th the education i had in my birth place, that wasn't any kind of education. i wanted more. and there was nothing there for me to want
Schistosomiasis is a parasite. This parasite is a worm that you get through contaminated water. Urine and feces usually contaminate the water. The worm goes in to your body and migrates to the bladder, rectum, liver, lungs, spleen, intestines and some veins. After the worm migrates to these places this is where it matures and lays its eggs. The disease has the ability to lay two thousand to three thousand eggs per day and can live for twenty years. There are five different kind of Schistosomiasis that effect humans, these different kinds are; S. mansoni, S. Heamatobium, S. japonicum, S. intercalatum and S. mekongi. There are also other kinds of Schistosomiasis that occasionally infect humans, there are; S. bovis, S. mathei, and some avian schistosomes.
Treponema pallidum is a Gram-negative bacterium that has a spiral shape (1). They are about 6 to 20um in length and 18-20um in diameter (1). Treponema pallidum can only survive within a host which makes them obligate internal parasites, meaning that outside a host this organism will die due to the absence of nutrients, exposure to oxygen and heat. Also since this organism can’t be grown on a culture medium, animal models are used to study T. pallidum (1). Treponema pallidum bacteria consist of an inner and outer membrane with a thin peptidoglycan cell wall lacking liposaccharides (1). They have a distinctive corkscrew motility with the aid of 6 endoflagellas (2). The specific classifications of Treponema pallidum are the following: Scientific name- Treponema pallidum, Common name- Syphilis. Treponema causes syphilis, yaws, and spinta. Borrelia causes Lyme disease and relapsing fever and Leptospira causing leptospirosis (5). What makes this microorganism special to the human population is that it causes infection to its host by entering the body through microscopic skin or mucous abrasions via direct personal contact with the lesions (sexual or kissing), blood transfusions, accidental bacterial inoculation, and transplacental passage (2). According to the CDC website there are 55,400 people diagnosed with Syphilis every year and 322 reported cases of congenital Syphilis in 2012 (6).
Canine Heartworm Disease can also be transmitted to puppies through the placenta of an infected mother. However in this case the puppies will only be carriers, but this makes them at risk of severe reactions when starting canine heartworm prevention. Another way larvae can be passed is through blood transfusions. To prevent this all donors must be cleared of heartworm disease before donating. Dogs infected with Canine Heartworm Disease can have from 1 to 250 worms living in them for 5 to 7 years.
Merriam-Webster defines ‘parasite’ as ‘an organism that lives in or on another organism and benefits by deriving nutrients at the host 's expense’.
Flatworms belong to the phylum Platyhelminthes. They have the simplest body plan of all bilaterally symmetrical animals. They are called flatworms because their bodies are compressed. The mouth is the only opening into the digestive cavity the flatworms have. Food is taken in through this hole and wastes are discharged also through this hole. Flatworms have a well-defined nervous, muscular, excretory, and reproductive system. The flatworm distributes the food it digests through a digestive tube that branches throughout all of its body parts. The fact that the worm’s body is flat serves many purposes. It allows the worm to hid in small spaces, to fit into the opening of other animals if the worm is parasitic, and it means that all the cells are close enough to the surface for exchange of oxygen and carbon dioxide with the environment (Meinkoth 399).
Worms. It's not something that most dog-owners want for their beloved pups; but unfortunately, it's something that happens all too often. Worms and other parasites aren't just disgusting to think about, they are also potentially dangerous. At the first suspicion—or sight—of worms, you should take action quickly, so that your family pet doesn't suffer from upset tummy, grumpy behavior, or death.
This 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.
According to the U.S. Food and Drug Administration on their website Animal and Veterinary it states the following. (Show a slide of how the heartworms are transferred)

In order for you to understand how Echinococcus works. You have to understand how it is transmitted into your system and begins infecting you. Echinococcus goes through several different steps on how it is developed and then transmitted to other hosts. The adult echinococcus tapeworm is about 5 mm long and lives in the small intestines of dogs and another canine species such as coyotes, wolves and foxes. The stage where a cyst begins usually occurs in intermediate hosts; typically sheep’s but they can also affect cattle’s, horses, camels, pigs and goats and many others. Tapeworm eggs are passed by the feces of infected dogs and then are digested by grazing sheep’s. These eggs then hatch into the embryos within the intestines, and then penetrate the intestines to be carried by the blood to major organs such as the liver and lungs. This larval stage of the parasite is called an oncosphere. The larval stage spreads by the bloodstream to target organs and other parts of the body, such as liver, lungs, ...
