Trichinella spiralis has an extremely broad host range; almost any species of mammal can become infected. Adult worms live around the columnar epithelial cells of the small intestine and the larvae live in striated muscle cells of the same mammal.

Where does Trichinella live?
Adult Trichinella spp. reside in the intestinal tract of the vertebrate host; larvae can be found encapsulated in muscle tissue.
What mammal tissue does the Trichinella infect?
Trichinella spiralis is an intracellular parasitic nematode of mammalian striated muscles, found worldwide in many carnivorous and omnivorous animals.
How do animals get infected with trichinosis?
Trichinellosis, also called trichinosis, is caused by eating raw or undercooked meat of animals infected with the larvae of a species of worm called Trichinella.
Where is Trichinella spiralis found in pork?
spiralis adults invade the intestinal wall of a pig, and produce larvae that invade the pig's muscles. The larval forms are encapsulated as a small cystic structure within a muscle cell of the infected host.
What is the reservoir for trichinosis?
RESERVOIR: Pigs, horses, bears, and game animals are most important reservoirs for Trichinella spp. leading to its transmission to humans(2,3). Synanthropic animals (e.g. rats) may also act as reservoirs for Trichinella spp. (1).
Is there trichinosis in Australia?
Trichinellosis is not present in mainland Australia and incursion would have considerable public health, trade and animal health implications. Ongoing surveillance, research and prevention strategies are important to ensure the parasite is not introduced to Australia in meat products or wildlife.
Is Trichinella a bacteria?
What is trichinosis? Trichinosis is a food-borne disease caused by a microscopic parasite called Trichinella. People can get this disease by eating raw or undercooked meat from animals infected with the parasite. Often these infected meats come from wild game, such as bear, or pork products.
Where is anisakis?
Anisakiasis is most commonly found in areas where eating raw fish is popular, such as Japan. However, since eating undercooked fish is becoming more common, there have been cases seen in the United States, Europe, South America, and other areas of the world. Anyone who eats undercooked or raw fish or squid is at risk.
What type of organism is Trichinella spiralis?
Trichinella spiralis is a nematode (roundworm) parasite. [1] It possesses the capability of infecting a wide range of mammals including pigs, horses, reptiles, and birds but it causes disease only in humans.
Do all pigs have trichinosis?
Only free-ranging and backyard pigs are at risk for Trichinella infection. Trichinella parasites cannot reach pigs reared under controlled housing conditions. Trichinella control should be risk-based oriented. Each year, millions of pigs worldwide are tested for Trichinella spp.
How common is trichinosis in Canada?
Nevertheless, approximately 18 cases of human trichinellosis are reported each year in Canada. Cases are generally attributed to the consumption of infected meat from wildlife.
Can you see trichinosis in meat?
The parasite is microscopic, so it cannot be seen in infected meat with the naked eye. Although Trichinella infection can be prevented in pigs that are raised for pork, there are no feasible methods for reducing Trichinella infection in wild animals.
Where do larval Trichinella worms live?
Trichinella spiralis has an extremely broad host range; almost any species of mammal can become infected. Adult worms live around the columnar epithelial cells of the small intestine and the larvae live in striated muscle cells of the same mammal.
Is trichinosis common in the UK?
Trichinosis is one of the most widespread foodborne parasitic diseases and occurs in most countries of the European Union (EU). There have been no human cases acquired from meat produced in the UK for over 30 years.
In which countries is trichinosis considered endemic?
In South and Central America, Trichinella infection is still endemic in Argentina, Chile, and Mexico in both humans and pigs (111, 144, 148). In East Asia, the domestic cycle occurs in China (158).
