Is Risk Of Roposis Dangerous?

Parasitical Worms.com Introduction Trichiasis is the result of Trichinella spiralis infection. People infected by chance when eating meat containing trichinella larvae that have not cooked enough. Most infections of this parasite are asymptomatic, although severe exposure can cause various clinical manifestations, including fever, diarrhea, muscle aches, and fatigue.
Pathogenesis - pathophysiology
Although 8 species of Trichinella currently exist and are described in terms of taxonomy based on genetic, biochemical and biological data, an additional 4 genotypes are recognized in this genus (genus)

. Their classification is uncertain. The following table describes the species in terms of their descriptive taxonomy, including their distribution, primary host, human infection, resistance to freezing, and human pathogenesis.
Trichinella species require two hosts to maintain their life cycle After growing in a single host, they continue to spread through the ingestion of infected meat, unlike traditional thrifty intermediate hosts Trichinella species have three main life cycles in the wild: pigs to pigs, mice to mice, and through carnivores (monivore) in the wild. Rats and pigs are the animals most commonly associated with helminth disease; however, depending on the region, walruses, seals, bears, bears, polar bears, cats, raccoons, wolves, and foxes can also be infected.



. The life cycle of Trichinella is depicted in the figure below.
The life cycle begins when eating raw or undercooked meat containing larvae that can grow inside a cocoon capsule, which is considered a nourishing cell. In the gastric acid environment of the host will make notebooks and release larvae from cocoon cysts. The larvae freely move into the small intestine and attach to and penetrate the mucosa at the base of the intestinal villi. After 4 transformations (molt: moult: hair loss, molting) and within 30-36 hours, they develop into adult worms and become mandatory intracellular organisms Adult males are approximately 15 x 0.05 mm, and adult females are approximately 3.5 x 0.06 mm.



. About 5 days after infection with the worms, the offspring begin spreading new live larvae (stage L1). The female remains in the gut for 4 weeks, laying up to 1,500 larvae. After causing a satisfactory inflammatory response in the intestine, the female eventually gets rid of in the stool.
Newborn larvae invade the lymphatic system and blood circulation and move to vein striated muscles - where blood supply is adequate The parasite has a tropism with most active metabolic groups; Therefore, the muscles most commonly infected with parasites include the tongue, diaphragm, chewing muscle, intercostal muscle, larynx, extraocular, nape, and pectoral muscles; delta muscles, buttocks, biceps (biceps), and calf muscles (gastrocnemius). In tissues other than striated muscle, such as the heart and brain muscles, the larvae soon disintegrate, causing intense inflammation, and then being reabsorbed.
The larvae continue to grow for the next 2-3 weeks until they reach the full development stage of L1 infection, and then they grow to size 10 times. Adult worms do not lay eggs (viviparous: spawn). The larvae curl up and grow into a cocoon cyst, or a nourishing cell (except T. pseudospiralis, which does not form a cocoon cyst).



. The complete cycle takes 17-21 days. The larvae inside the cyst walls reach an average size of 400 x 260 µm, however, there are also children with a length of 800-1,000 µm Complex L1 - nourishing cells can survive 6 months to several years before calcification and death. This life cycle is completed when a compatible host eating muscle is infected with helminth larvae.
The intensity and frequency of contact with helminth larvae determines the severity of the disease. Infections were classified as mild (ingesting 0-10 larvae), moderate (ingesting 50-500 larvae), and severe (ingesting> 1,000 larvae).
Epidemiology and frequency of infection
United States
From 1997-2001, 72 cases of helminth infections were reported to the Centers for Disease Control and Prevention (CDC). Most cases are related to wildlife predatory games (43%), although 17% are related to commercial pork products and 13% are related to domestic pork products. Infection can also occur during foreign travel, especially to Mexico and Asia. The rate of domestic infected pigs in the United States was 0.



001%; however, an autopsy literature studies a 4% incidence of old helminth infections. The data also shows the presence of T. murrelli in raccoons and coyotes.
international
In Europe, where pork supervision is mandatory, most cases of helminthosis involve horse meat or wild boar. In Latin America and Asia, domestic pork is the main source of infection. Trichinella infection rate in pigs in China is about 20%. Studies have also reported an increase in the prevalence of gum disease.
