  • Helminthiases,
    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
    years.


    Sources of infection

    Sexually
    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.


    Ways of infection diphyllobothriasis

    diphyllobothriasisdefinitive
    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

    Cycle
    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

    clinical
    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.


    The effects of parasitism

    AT
    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.


    Methods of diagnosis diphyllobothriasis

    Detection of eggs and segments in the feces, expectoration of "tape" parasite.



    diphyllobothriasis Treatment

    at
    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.



    prevention

    diphyllobothriasis

    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.
