Trichinella
''Trichinella'' is the genus of parasitic roundworms of the phylum Nematoda that cause trichinosis (also known as trichinellosis). Members of this genus are often called trichinella or trichina worms. A characteristic of Nematoda is the one-way digestive tract, with a pseudocoelom (body cavity made up of only an ectoderm and endoderm). The genus was first recognised in a larval form in 1835. The L1 larvae live in a modified skeletal muscle cell. The adult worms occupy a membrane-bound portion of columnar epithelium, living as intramulticellular parasites of animals, including humans. Infections with this genus have been reported from more than 150 different naturally or experimentally infected hosts. It has been shown to have a worldwide distribution in domestic and/or sylvatic animals. ''Trichinella'' is the smallest human nematode parasite, yet it is also the largest of all intracellular parasites. Oral ingestion of cyst- or larvae-contaminated tissue is the usual route of ...

Trichinella Spiralis
''Trichinella spiralis'' is a viviparous nematode parasite, occurring in rodents, pigs, bears, hyenas and humans, and is responsible for the disease trichinosis. It is sometimes referred to as the "pork worm" due to it being typically encountered in undercooked pork products. It should not be confused with the distantly related pork tapeworm. Description ''Trichinella'' species, the smallest nematode parasite of humans, has an unusual life cycle, and are one of the most widespread and clinically important parasites in the world. The small adult worms mature in the small intestine of a definitive host, such as a pig. Each adult female produces batches of live larvae, which bore through the intestinal wall, enters the blood (to feed on it) and lymphatic system, and are carried to striated muscle. Once in the muscle, they encyst, or become enclosed in a capsule. Humans can become infected by eating infected pork, horsemeat, or wild carnivores such as fox, cat, hyena or bea ...

Trichinella Britovi
''Trichinella britovi'' is a nematode parasite responsible for a zoonotic disease called trichinellosis. Currently, eight species of ''Trichinella'' are known, only three of which cause trichinellosis, and ''Trichinella britovi'' is one of them. Numerous mammal species, as well as birds and crocodiles, can harbor the parasite worldwide, but the sylvatic cycle is mainly maintained by wild carnivores. Humans represent only a possible host and the parasite is exclusively transmitted through consumption of raw or Rare Meat. In Europe, pork and wild boar meat are the main sources for human infection. Because of mandatory veterinary controls in slaughterhouses, large trichinellosis outbreaks due to horse-meat consumption are rare, but cases in hunters and their families after raw or rare wild boar meat consumption are regularly reported, with over 100 cases since 1975. ''Trichinella britovi'' can be found in Europe and western Asia among carnivores such as wild boars, pigs, bear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Digestion
Artificial digestion is a laboratory technique that reduces food to protein, fat, carbohydrates, fiber, minerals, vitamins, and non-nutrient compounds for analytical or research purposes. Digestive agents such as pepsin and hydrochloric acid are typically used to accomplish artificial digestion. Meat inspection Artificial digestion is used to detect the presence of encysted trichinella larvae in suspected muscle tissue. Prior to this method, a sample of muscle tissue was compressed to visually express the encysted parasite. Using artificial digestion, meat samples are dissolved by a digestive solution and the remains are examined for the presence of larvae. Digestion research Artificial stomach and small intestine models are used instead of laboratory animals or human test subjects. Various models, from static one-compartment to dynamic multicompartment, exist. These models are used to study food digestion and subsequent bioavailability. References See also * Digestion Dig ...

Trichinosis
Trichinosis, also known as trichinellosis, is a parasitic disease caused by roundworms of the '' Trichinella'' genus. During the initial infection, invasion of the intestines can result in diarrhea, abdominal pain, and vomiting. Migration of larvae to muscle, which occurs about a week after being infected, can cause swelling of the face, inflammation of the whites of the eyes, fever, muscle pains, and a rash. Minor infection may be without symptoms. Complications may include inflammation of heart muscle, central nervous system involvement, and inflammation of the lungs. Trichinosis is mainly spread when undercooked meat containing ''Trichinella'' cysts is eaten. Wild meat is more likely to contain the parasite. In North America this is most often bear, but infection can also occur from pork, boar, and dog meat. Several species of ''Trichinella'' can cause disease, with ''T. spiralis'' being the most common. After the infected meat has been eaten, the larvae are release ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thiabendazole
Tiabendazole (International Nonproprietary Name, INN, British Approved Name, BAN), also known as thiabendazole (Australian Approved Name, AAN, United States Adopted Name, USAN) or TBZ and the trade names Mintezol, Tresaderm, and Arbotect, is a preservative, an antifungal agent, and an antiparasitic agent. Uses Preservative Tiabendazole is used primarily to control Mold (fungus), mold, blight, and other fungal diseases in fruits (e.g. Orange (fruit), oranges) and vegetables; it is also used as a prophylaxis, prophylactic treatment for Dutch elm disease. Tiabendazole is also used as a food additive, a preservative with E number E233 (INS number 233). For example, it is applied to bananas to ensure freshness, and is a common ingredient in the waxes applied to the skins of citrus fruits. It is not approved as a food additive in the EU, Australia and New Zealand. Use in treatment of aspergillosis has been reported. It is also used in anti-fungal wallboards as a mixture with a ...

Spotted Hyenas
The spotted hyena (''Crocuta crocuta''), also known as the laughing hyena, is a hyena species, currently classed as the sole extant member of the genus ''Crocuta'', native to sub-Saharan Africa. It is listed as being of least concern by the IUCN due to its widespread range and large numbers estimated between 27,000 and 47,000 individuals. The species is, however, experiencing declines outside of protected areas due to habitat loss and poaching. Populations of ''Crocuta'', usually considered a subspecies of ''Crocuta crocuta'', known as cave hyenas, roamed across Eurasia for at least one million years until the end of the Late Pleistocene. The spotted hyena is the largest extant member of the Hyaenidae, and is further physically distinguished from other species by its vaguely bear-like build, rounded ears, less prominent mane, spotted pelt, more dual-purposed dentition, fewer nipples, and pseudo-penis. It is the only placental mammalian species where females have a pseudo-penis a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apex Predators
An apex predator, also known as a top predator or superpredator, is a predator at the top of a food chain, without natural predators of its own. Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels. Food chains are often far shorter on land, usually limited to being secondary consumers – for example, wolves prey mostly upon large herbivores (primary consumers), which eat plants (primary producers). The apex predator concept is applied in wildlife management, conservation, and ecotourism. Apex predators have a long evolutionary history, dating at least to the Cambrian period when animals such as ''Anomalocaris'' and '' Timorebestia'' dominated the seas. Humans have for many centuries interacted with other apex predators including the wolf, birds of prey, and cormorants to hunt game animals, birds, and fish respectively. More recently, humans have started interacting with apex predators in new ways. These inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Union
The European Union (EU) is a supranational union, supranational political union, political and economic union of Member state of the European Union, member states that are Geography of the European Union, located primarily in Europe. The union has a total area of and an estimated population of over 449million as of 2024. The EU is often described as a ''sui generis'' political entity combining characteristics of both a federation and a confederation. Containing 5.5% of the world population in 2023, EU member states generated a nominal gross domestic product (GDP) of around €17.935 trillion in 2024, accounting for approximately one sixth of global economic output. Its cornerstone, the European Union Customs Union, Customs Union, paved the way to establishing European Single Market, an internal single market based on standardised European Union law, legal framework and legislation that applies in all member states in those matters, and only those matters, where the states ...
