Tapeworm infection of
your intestine occurs
when men
and women consume
raw, contaminated pork, beef, or freshwater fish. Most folks
with tapeworms don't
have any tapeworm signs
or symptoms, but some report abdominal
discomfort, diarrhea, and loss of appetite.
Anemia could
create
in people
using
the fish tapeworm.
- Men and women obtain tapeworms by consuming undercooked meat or freshwater fish that contain tapeworm cysts.
- Tapeworms within the intestine normally cause no signs or symptoms but may possibly trigger stomach discomfort, diarrhea, and loss of appetite
- Depending on where they are, larval cysts cause various signs or symptoms, like headaches, seizures, and confusion
- Doctors diagnose the infection by discovering worm segments or eggs in a stool sample or, for cysts elsewhere in the body, by performing imaging or blood checks
- Completely cooking meat and freshwater fish can help stop the infection.
The pork and beef tapeworms are huge, flat worms that live in the intestine and can grow 15 to 30 feet in size. Egg-bearing sections from the worm are handed within the stool. If untreated human waste is launched to the atmosphere, the eggs may be ingested by intermediate hosts, like pigs, cattle, or (in the situation of fish tapeworms) little crustaceans, which are in turn ingested by fish. The eggs hatch into larvae within the intermediate host. The larvae invade the intestinal wall and are carried by means of the bloodstream to skeletal muscle as well as other tissues, exactly where they form cysts. People obtain the parasite by eating the cysts in raw or undercooked meat or specific kinds of freshwater fish. The cysts hatch and produce into grownup worms, which latch onto the intestinal wall. The worms then grow in length and start creating eggs.
For the pork tapeworm only, people who ingest the eggs can turn out to be an intermediate host. They could swallow the pork tapeworm eggs in food or h2o contaminated with human feces, or they may possibly transfer the eggs to their mouth right after make contact with with an contaminated individual or with contaminated clothes and furnishings. Or eggs may possibly attain the belly if proglottids are regurgitated through the intestine. As in animal intermediate hosts, the eggs cultivate into larvae. The larvae penetrate the intestinal wall and journey to your brain (see Infections of the Brain and Spinal Cord: Parasitic Infections), muscles, other organs, or tissue beneath the skin, where they type cysts. In individuals, this form of the disease is referred to as cysticercosis.
Symptoms and Prognosis
Although tapeworms within the intestine usually trigger no signs and symptoms, some people encounter upper stomach discomfort, diarrhea, and loss of appetite. Sometimes, a person with a tapeworm can really feel a piece of the worm transfer out by way of the anus or see part from the ribbon-like tapeworm in stool. The fish tapeworm (Diphyllobothrium latum) can cause anemia since it absorbs vitamin B12, that is essential for red blood cells to mature.
Cysts inside the brain and also the tissues covering the brain (meninges) in individuals with cysticercosis can result in headaches, seizures, confusion, or other neurologic symptoms. Rarely, cysts cultivate within the eyes, sometimes causing blindness, or within the spinal cord, sometimes leading to muscle weakness or paralysis.
A doctor diagnoses intestinal tapeworm infection by discovering worm segments or eggs in a stool sample. In folks with cysticercosis, cysts in the brain or other tissues can be noticed using computed tomography (CT) or magnetic resonance imaging (MRI). Blood checks for antibodies to the pork tapeworm may also be useful.
Prevention and Therapy
The initial line of defense against tapeworms is totally cooking meat and freshwater fish to a temperature of much more than 135° F (57° C). Prolonged freezing can also kill cysts. Therefore, freshwater fish really should not be served as sushi, and needs to be eaten only following it is cooked, properly frozen, or cured in brine. Smoking and drying do not destroy cysts. An additional line of defense is careful evaluation of meat and fish by educated inspectors. Cysts are visible in contaminated meat. Satisfactory therapy of human waste interrupts the lifestyle cycle and thus assists stop cysticercosis.
