Tapeworms are flat segmented worms that have a head, neck, and segments called proglottids; the scientific name is Cestoda the flatworm. Animals become infected with these tapeworms from grazing in pastures that have tapeworms in the grass and from drinking water that is contaminated with the tapeworms. When Humans eat the meat from these animals raw or not cooked all of the way they become infected with the tapeworms. Humans can also become infected by drinking contaminated water. Generally the symptoms of being infected with these tapeworms in humans is so mild that they are not recognized and can easily be treated, although in some cases it can become very dangerous.
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.
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.
There is a constant battle for farmers to find new and cost effective ways to rid their flock from endoparasites, in particular worms. Endoparasites are a parasite, for example worms, that live in the internal organs or tissues of a host. The most common species of worms that live amongst sheep in Australia are Haemonchus contortus (barbers pole worm), Trichostrongylus colubriformis (Black scours worm) and Teladorsagia circumcincta (brown stomach worm); all of these worms are examples of roundworms. The type of roundworm that is most commonly found in Queensland and the northern half of NSW is the barber’s pole worm. This is due to the climate of these two States where summer rainfall is common or dominant. The barber’s pole worm is located
The new guinea flatworm is from the united states of America.this worm is native to the island of New Guinea where it was originally to have been found in. You can find these worms in tropical areas,coastlands ,planted forests, riparian zones shrubs and urban areas as well.it feeds on earthworms ,slugs and arthopods. This worm can harm the snail called The Giant East African Snail. This worm also can mainly eat mollusks and it especially likes to prey on snail. To hunt for it's prey the worm deposits itself to the bottom of a cabbage leave. It also can follow snail mucus trails to find it`s trail. It also has a infectious rate at least 14.1% and this thing usually lives on cabbage leaves. This worm not only affects the whole population of animals or a specific area this worm can affect humans as
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
Glow worms are found in the artic, caves, and in dense woodland. Glow worms are animals that tend to have a meat based diet. They eat slugs, snails, and other small insects. The glow worm’s conservation status is threatened. The glow worm is long and fat. They are really small. And they have a green light on their tail.
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,
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.
Scalp ringworm (tinea capitis) is a fungal infection of the skin on the scalp. This condition is easily spread from person to person (contagious). Ringworm also can be spread from animals to humans.
The purpose of this assignment is to learn, observe and experience the biology of the Tobacco Hornworm through the different stages of its lifecycle, along with describing the processes which occur through each development stage. When I picked up my hornworm, I received three eggs in the tubular container. During my examination, the hornworms lived in two environments. They first lived in the small, tubular container they arrived in until they outgrew it. I then placed them in a large plastic container for the remainder of their lifecycle.
How the disease was transmitted was further looked on by Nelson (1995). According to the said author, the disease was transmitted primarily by fleas and rats. The stomachs of the fleas were infected with bacteria known Y. Pestis. Nelson held that “the bacteria would block the "throat" of infected fleas so that no blood could reach their stomachs, and they grew ravenous since they were starving to death” (1995, par. 14). The bacteria would then attempt to suck up blood from their victims, only to disgorge it back into their preys' bloodstreams (Nelson, 1995). Now, however, the victims' blood was mixed with Y. Pestis. Fleas infected rats in this fashion, and the rats spread the disease to other rats and fleas before dying (Nelson, 1995). Without rodent hosts, the fleas then migrated to the bodies of humans and infected them in the same fashion as they had the rats .
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
Schistosomiasis have three different names and these are bilharzia, snail fever, and Katayama fever (Mawyer, 2013). It is a disease caused by parasites, meaning they live off the living host to survive. Examples of parasitic organism are viruses, protozoa, and helminthes. They are flatworm or fluke, known as Schistosomes and they cause Schistosomiasis disease. Schistosoma is the spices name and Trematoda is the class that the organism falls under. Helminthes is the group or family of Schistosoma ((Keas, 1999). These organisms are facultative anaerobic, and they have the ability to move around in water and in the host bloodstream. They reproduce sexually and asexually depending on the stage of development; they are intracellular parasites at the mature stage. They live in water in the immature state. Schistosomes are flatworm and are different from other worms because they compose of the female and the male worm. The adult female worm is longer (1.5-2cm) than the male worm (1-1.5cm). The female worm produces several hundreds of eggs daily to enhance its survival rate. An adult life span of a Schistosome can go up to 5 to 10 years, so you can image how dangerous this infection is (Ferrara, 2010).
