called parasitism in the human gut broad tapeworm
(Diphyllothrium latum) the largest tape helminth. Length
adult reaches 9-18 meters.
Helminths are parasitic in the small intestine of humans and animals,
affect the liver, bile duct, muscle tissue, internal
authorities. Every year in Russia diphyllobothriasis ill more
20 thousand people. Diphyllobothriasis distributed mainly in
Krasnoyarsk region, Republic of Karelia, the Kola Peninsula and the coastal regions.
Lifespan broad tapeworm in the human body - 25
tapeworm parasitic in the small intestine of definitive hosts
(People, dogs, cats, foxes, foxes, martens, rarely can become infected
swine); larvae (plerocercoids) - in various organs and tissues
Additional hosts (freshwater fish: perch, ruff, trout, burbot,
pike, grayling, whitefish, perch, bullhead). The intermediate hosts are
crustaceans - Cyclops. Therefore, the source of the disease to humans are
all of these kinds of animals and fish.
hosts (human, dog, cat) are infected by eating raw or insufficiently
thermally processed fish infected with larvae difillobotriid.Eto
It can be planed frozen fish (steak), raw fish
minced meat, poorly roasted fish, insufficiently salted roe. AT
the intestines of dogs and cats a tapeworm reaches sexual maturity for
13-23 days and lives in the intestines of dogs 394 days, 21-27 days of cats.
Life expectancy of helminth in humans of up to 29 years.
The forms of existence
the development of the parasite is associated with an aqueous medium - highlights of tapeworm
the body of the final master's immature eggs, which is the development of
at freshwater. The embryo of the egg goes into the water after 1-2
Time remaining viable up to 6 months. They are willing to eat
small crustaceans - Daphnia and Cyclops, in which the intestine 2-3
weeks, they turn into larvae (procercoids). In turn, the minor
crustaceans become the prey of small fish, the body of which the larva
He continues to ripen. The infectious to human form larvae
become a big fish in the body, usually prey, ate
small larvae infected fish. In the sexually mature form of tapeworm
It is converted in the body of the final host.
Symptoms of the disease course diphyllobothriasis
picture diphyllobothriasis expressed gastrointestinal disorders
tract as helminth exerts a mechanical effect on the wall
bowel in place of attachment. The disease begins gradually.
Nausea, vomiting, pain during bowel becomes chair
unstable, fever appears. For this very helminthiasis
characterized by severe weight loss with increased appetite.
cases of prolonged course of intestinal helminthiasis comes
obstruction due to the accumulation of a large number of worms in the small
intestine. In severe cases, affected the cardiovascular and nervous
system, developed B12 vitamin deficiencies (helminth absorbs it in a particularly
large quantities throughout the body surface), anemia, atrophy and necrosis
the intestinal wall; allergic reactions.
Detection of eggs and segments in the feces, expectoration of "tape" parasite.
severe anemia before deworming prescribe vitamin B12
intramuscularly, iron supplements, gemostimulin, hematogen.
Deworming is carried out single dose of praziquantel and
used fenasal extract of male fern, decoction of pumpkin seeds.
For the prevention of obvious need for careful
thermal processing of fish and eggs before eating. pickling
brine fish 24C fortress at Boma kills the larvae within 7-8 days. AT
calf deaths plerocercoids occurs at 3% salted (3 g of salt per 100g
calves) in 2 days, at 5% - 30 min. When freezing pike
weighing about 2 kg at 18 C larvae die within four days.
