Sheep Tapeworm Essay

In George Orwell’s novel Animal Farm, a major turning point in the novel was when Napoleon used his secret police force, his dogs, to exile Snowball. Snowball had previously been trying to improve the animal’s lives for the future by building a windmill. After Snowball was exiled, Napoleon became leader and everything immediately went amiss. Orwell stated that: "Somehow it seemed as though the farm had grown richer without making the animals themselves any richer- except, of course, for the pigs and the dogs" (p.86). In other words, no one was benefiting from the animal’s labours apart from the pigs and the dogs because the amount of authority the dogs and the pigs, especially Napoleon had, was corrupt. Frighteningly, if Snowball had been

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

A person can obtain a tapeworm parasite through the ingestion of raw meat from infected animals or by consuming the parasite in tablet form. After a person consumes a tapeworm, traveling through the body, eating as it moves around. The tapeworm usually consumes a significant portion of a person’s food to cause a calorie shortage and weight loss. Certain tapeworms can grow up to 15-30 feet in length and live up to 20 years in the host. When the tapeworm dieter decides that they have lost enough weight, they take antibiotics to kill the parasite, eventually leaving the body in a bowel movement. People have been known to take drugs designed to reduce the lifespan of the tapeworm so that it is already dead when it is removed from the body.

Tapeworms are rare in the United States nowadays. Since they are passed on by undercooked beef, pork, and fish, there are protocols to be followed so people can be assured their food is safe. Most cases of tapeworms stem from people who have left the country. These parasite’s anatomy is very useful for their environment. The skin will absorb food rather than ingesting it, and the body is perfect for latching onto the intestine walls. The head is slightly knob-like and is rimmed with tiny hooks. Most species need a mate to reproduce, but in some species of tapeworms, internal fertilization is possible. After storing the eggs, the outer layer of the body will shed, allowing the eggs to leave the host or hatch and return to the intestine. Tapeworms will live in the

A developed giant tubeworm does not have a digestive tract, mouth or stomach and does not produce its own energy like the chemosynthetic bacteria. Instead it relies on a symbiotic relationship with certain species of bacteria for survival, which are found in huge colonies within the worm, up to 285 million per ounce of tissue. Initially the tubeworm exists as a non-symbiotic larva, which acquires the symbiotic bacteria via its digestive tract. After this point the worm continues to grow and its morphology alters significantly with the gut transforming into a trophosome for the bacteria to reside

C.Elegans are roundworms or threadworms that are 1mm in length and found living within soil around many parts of the world, these C. Elegans thrive on rotting vegetation where it can survive, feeding on microbes such as bacteria, these C. Elegans are non-infectious, non-pathogenic and non-hazardous. They are of a long cylindrical shape that looks rather tapered at each end. These worms are found in both aquatic and terrestrial free living environment’s.

“Wereworms. I don’t even know why I’m surprised anymore.” Gemma pushed her hair out of her face, suddenly just feeling overwhelmingly exhausted. “That’s what those massive things that burst out of the rock were?”

Parasitic nematodes cause diseases of major economic importance in sheep .The lungworm , Dictyocaulus filaria , represents one of these nematodes inhabits bronchi and bronchioles and cause parasitic bronchitis (commonly known as ‘husk) particularly in young sheep ( Holzhauer et al., 2011). Dictyocaulus filaria has direct life cycle, embryonated eggs are coughed up or swallowed and hatch in the small intestine then first-stage larvae are passed in faeces. Under favorable environmental conditions, first-stage larvae moult to second-stage larvae and then infective en-sheathed third-stage larvae that actively move from faeces to herbage and are ingested by the grazing sheep. Following ingestion, third-stage larvae ex-sheath in

Echinococcosis is a term used to describe a potentially lethal zoonotic disease caused by tapeworms from the genus Echinococcus. Disease states can be further subclassified into either cystic echinococcosis (caused by Echinococcus granulosus) or alveolar echnicoccosis (caused by Echinococcus multilocularis), depending on the infecting organism.

A tapeworm infection attacks the digestive tract of its host and they require an intermediate host to complete their life cycle. The actual tapeworms are a species of parasitic flatworm know as a cestode. It is a long, thin worm that attaches itself to the intestine of the host by a sucker or hooks in its head. The body of the worm is made up of detachable segments and, as the segments mature, thousands of eggs form in each segment. The segments are expelled with the feces of the host and are still packed with eggs. Species affected by the tapeworm include dogs, horses, cattle, sheep, goats, pigs, and poultry. Humans are also

Tapeworms (cestodes) are multi-segmented flat worms that parasitize the intestine of the definitive host (of humans as an example) , each segment of the chain is a separate reproductive unit, the proglottid, which if broken from the main body, is capable of independent regrowth into a fully segmented worm (with multiple proglottids). With proglottids attached, the entire chain moves as a single unit, in rhythmic fashion.The tapeworm is anchored to the intestinal lining by one end of the chain via the scolex. The scolex is minute, maybe a less than one millimeter or a few millimeters, in comparison to the entire tapeworm chain which may be a few millimeters to several meters in length. The scolex contains various mouth parts or

Maximum body size of the worms is about 10cm (200-250 segments), and 1.5 millimeters in diameter. Distinguishing head and tail ends isn’t difficult because the head is a darker color, as well as the fact that the tail isn’t as wide and mobile as the head. Notable anatomical parts appearing in the first ten of these worm’s segments include a conical prostomium, muscular pharynx, as well as male and female sex organs (Drewes, 1999), which forces worms onto the label of hermaphrodite (Brinkhurst, Gelder, 1991The head and tail ends appear to favor each other, but there are vital differences in their bodily roles and structure. These differences are often subtle and gradual, often being shown as anterior-posterior gradients affecting all organ

Acorn worms get their names Hemichordates from having some of the characteristics of a chordate. “Hemi” meaning half and then adding chordate. They are both also part of the deuterostomes family by having their first opening to be the anus. There are certain characteristics that make acorn worms part of the deuterostomes family including a bilaterally symmetrical body, radial cleavage, enterocoelous coelom, and invertebrate. Bilaterally symmetrical meaning that the acorn worm can be open right down the midline and both sides of the worm would be exactly the same. The enterocoelous meaning that the acorn worm has a true body cavity which forms of the embryonic mesoderm as the evaginations of the gut and also that the anus is the first opening

Angiostrongylus cantonensis are found in rodents where the worms are able to reproduce, ensuring its continuity. The larvae resides in rat lungs where it lays eggs in pulmonary arteries and subsequently hatch and migrate via the trachea and gastro- intestinal tract into rat feces. Eliminated

Veterinary medicine is the branch of medicine that deals with the diseases of animals. Treating pets is one of the most profitable fields in veterinary medicine. The proper vaccination of animals and the diagnosis of diseases are part of a veterinarian’s duties.
