Anoplocephala Perfoliata
''Anoplocephala perfoliata'' is the most common intestinal tapeworm of horses, and an agent responsible for some cases of equine colic. Description Between 8 and 25 centimeters long, ''Anoplocephala perfoliata'' is part of the order Cyclophillidea and is one of the three tapeworm species that can infect horses. This parasite is the most common intestinal tapeworm of horses in the world and is one of the top causes of equine colic. Any horses that have access to pastures and grazing are likely to have an ''A. perfoliata'' tapeworm in their body and experience no symptoms. The other two species which can infect horses are '' A. magna'' and '' Paranoplocephala mamillana''. ''A. perfoliata'' can be found in the intestinal tract of a horse at the ileocecal junction as well within the cecum and the ileum themselves. Life cycle This parasite follows the general Cyclophillidean life cycle diagrammed in Figure 1. These parasites prefer rich, grassy areas and are not often found in ari ...

Johann August Ephraim Goeze
Johann August Ephraim Goeze (; 28 May 1731 – 27 June 1793) was a German zoologist, born in Aschersleben. He is known for the discovery of tardigrades, also called water bears. He was the son of Johann Heinrich and Catherine Margarete (née Kirchhoff). He studied theology at University of Halle. He married Leopoldine Maria Keller in 1770, by whom he had four children. In 1751, he became a pastor in Aschersleben, in Quedlinburg, and later of in Quedlinburg in 1762, finally becoming first deacon of the seminary of Quedlinburg in 1787. He died in Quedlinburg. He did much work with aquatic invertebrates, particularly insects and worms. In 1773, he was the first to describe tardigrades. In 1784, Goeze perceived the similarities between the heads of tapeworms found in the human intestinal tract and the invaginated heads of '' Cysticercus cellulosae'' in pigs. Works *Goeze, J. A.

Horse Colic
Colic in horses is defined as abdominal pain, but it is a clinical symptom rather than a diagnosis. The term colic can encompass all forms of gastrointestinal conditions which cause pain as well as other causes of abdominal pain not involving the gastrointestinal tract. The most common forms of colic are gastrointestinal in nature and are most often related to colonic disturbance. There are a variety of different causes of colic, some of which can prove fatal without surgical intervention. Colic surgery is usually an expensive procedure as it is major abdominal surgery, often with intensive aftercare. Among domesticated horses, colic is the leading cause of premature death. The incidence of colic in the general horse population has been estimated between 4 and 10 percent over the course of the average lifespan. Clinical signs of colic generally require treatment by a veterinarian. The conditions that cause colic can become life-threatening in a short period of time. Pathophysiolog ...

Horse Diseases
The horse (''Equus ferus caballus'') is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of ''Equus ferus''. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, ''Eohippus'', into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies ''caballus'' are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, as this term is used to describe horses that have never been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior. Horses are adapted to run, allowing them to quickly escape predators, and poss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moxidectin
Moxidectin is an anthelmintic drug used in animals to prevent or control parasitic worms (helminths), such as heartworm and intestinal worms, in dogs, cats, horses, cattle and sheep. Moxidectin kills some of the most common internal and external parasites by selectively binding to a parasite's glutamate-gated chloride ion channels. These channels are vital to the function of invertebrate nerve and muscle cells; when moxidectin binds to the channels, it disrupts neurotransmission, resulting in paralysis and death of the parasite. Medical uses Moxidectin was approved for onchocerciasis (river-blindness) in 2018 for people over the age of 11 in the United States based on two studies. There is a need for additional trials, with long-term follow-up, to assess whether moxidectin is safe and effective for treatment of nematode infection in children and women of childbearing potential. Moxidectin is predicted to be helpful to achieve elimination goals of this disease. * Dogs: Prevention ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Praziquantel
Praziquantel (PZQ), sold under the brandname Biltricide among others, is a medication used to treat a number of types of helminthiasis, parasitic worm infections in mammals, birds, amphibians, reptiles, and fish. In humans specifically, it is used to treat schistosomiasis, clonorchiasis, opisthorchiasis, Taeniasis, tapeworm infections, cysticercosis, echinococcosis, paragonimiasis, fasciolopsiasis, and fasciolosis. It should not be used for worm infections of the eye. It is taken Oral administration, by mouth. Side effects in humans may include poor coordination, abdominal pain, vomiting, headache, and allergic reactions. While it may be used during pregnancy, it is not recommended for use during breastfeeding. Praziquantel is in the anthelmintic class of medications. It works partly by affecting the function of the worm's Sucker (zoology), sucker. Praziquantel was approved for medical use in the United States in 1982. It is on the WHO Model List of Essential Medicines, World ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrantel Pamoate
Pyrantel is a medication used to treat a number of parasitic worm infections. This includes ascariasis, hookworm infections, enterobiasis (pinworm infection), trichostrongyliasis, and trichinellosis. It is taken by mouth. Side effects include nausea, headache, dizziness, trouble sleeping, and rash. A lower dose should be used in people with liver disease.

Proglottid
Cestoda is a class of parasitic worms in the flatworm phylum (Platyhelminthes). Most of the species—and the best-known—are those in the subclass Eucestoda; they are ribbon-like worms as adults, known as tapeworms. Their bodies consist of many similar units known as proglottids—essentially packages of eggs which are regularly shed into the environment to infect other organisms. Species of the other subclass, Cestodaria, are mainly fish infecting parasites. All cestodes are parasitic; many have complex life histories, including a stage in a definitive (main) host in which the adults grow and reproduce, often for years, and one or two intermediate stages in which the larvae develop in other hosts. Typically the adults live in the digestive tracts of vertebrates, while the larvae often live in the bodies of other animals, either vertebrates or invertebrates. For example, '' Diphyllobothrium'' has at least two intermediate hosts, a crustacean and then one or more freshwater fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Intussusception (medical Disorder)
Intussusception is a medical condition in which a part of the intestine folds into the section immediately ahead of it. It typically involves the small bowel and less commonly the large bowel. Symptoms include abdominal pain which may come and go, vomiting, abdominal bloating, and bloody stool. It often results in a small bowel obstruction. Other complications may include peritonitis or bowel perforation. The cause in children is typically unknown; in adults a ''lead point'' is sometimes present. Risk factors in children include certain infections, diseases like cystic fibrosis, and intestinal polyps. Risk factors in adults include endometriosis, bowel adhesions, and intestinal tumors. Diagnosis is often supported by medical imaging. In children, ultrasound is preferred while in adults a CT scan is preferred. Intussusception is an emergency requiring rapid treatment. Treatment in children is typically by an enema with surgery used if this is not successful. Dexamethasone ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oribatid Mite
Oribatida (formerly Cryptostigmata), also known as oribatid mites, moss mites or beetle mites, are an order of mites, in the "chewing Acariformes" clade Sarcoptiformes. They range in size from . There are currently 12,000 species that have been identified, but researchers estimate that there may be anywhere from 60,000 to 120,000 total species. Oribatid mites are by far the most prevalent of all arthropods in forest soils, and are essential for breaking down organic detritus and distributing fungi. Oribatid mites generally have low metabolic rates, slow development and low fecundity. Species are iteroparous with adults living a relatively long time; for example, estimates of development time from egg to adult vary from several months to two years in temperate forest soils. Oribatid mites have six active instars: prelarva, larva, three nymphal instars and the adult. All these stages after the prelarva feed on a wide variety of material including living and dead plant and fungal m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
