Ankilostomidoz (ankilostomosis and necatoriasis)



Etiology, pathogenesis. Pathogens - hookworm and necator, parasitic in the small intestine of a person, more often - in the duodenum. Infection occurs when the larvae penetrate the skin or if the larvae are swallowed with contaminated fruits, vegetables, and water. The larvae migrate in the large and small circle of blood circulation for about 7-10 days. In the small intestine, they turn into mature individuals and after 4-6 weeks begin to lay eggs. Hookworm life span ranges from several months to 20 years. In the period of migration can cause toxic-allergic reactions. Adult worms are hematophagous. When fixing to the intestinal mucosa, the mucosa and tissues are injured, which leads to the formation of hemorrhage, cause bleeding, contribute to the development of anemia, maintain a certain level of allergy, dyskinesia of the gastrointestinal tract and dyspepsia.

Clinic.
Skin itching and burning, asthma, fever, in the analysis of blood eosinophilia. In the late stage, nausea, drooling, abdominal pain, vomiting, bowel dysfunction (constipation or diarrhea), bloating appear.

The diagnosis is confirmed by the detection of eggs in the feces, and sometimes in the duodenal contents.

Treatment. De-worming is carried out with combantrin or levamisole. In cases of severe anemia (hemoglobin below 67 g / l), iron preparations and red blood cell transfusions are prescribed.

Prognosis and prevention. The prognosis is in most cases favorable.

Prevention: in the foci of ankilostomidoz it is impossible to walk barefoot, to lie on the ground without a litter. It is necessary to thoroughly wash and boil fruits, berries, vegetables with boiling water before eating them, you should not drink boiled water.

Ankilostomidoz (ankilostomosis and necatoriasis)

  1. Agriculture, livestock, land reclamation
    No less important factor in human economic activity is the intensification of agricultural production on the basis of agro-industrial complexes, farms and peasant farms. The transformation of agriculture leads to a change in the biocenotic relations in the foci of helminth infections that have developed in evolutionarily stable environmental conditions. With the industrialization of the village indigenous
  2. ANKILOSTOMIC ANEMIA
    Anemia of the post-hemorrhagic type is anemia caused by parasitic worms from the nematode class, ankilostomida. The peculiarity of this disease and the significant spread of ankilostomidosis in the southern latitudes are the basis for a separate description of this form of anemia. In the USSR, ankilostomidosis is known in some regions of Georgia (Abkhazia, Ajaria), Azerbaijan, and Turkmenistan.
  3. Nematodes
    Helminthiasis caused by nematodes, or helminths that are round in cross section (toxocarosis, toxascaris, uncinariosis, ankylostomosis, etc.) are the most common helminth infestations among cats. Nematodes are fairly small parasites whose dimensions rarely exceed a few centimeters. Outside the worms are covered with a cuticle, on which there may be spikes, papillae and other outgrowths,
  4. Nematodes
    Ascariasis Ascariasis is a person's helminthiasis caused by Ascaris lumbricoides round helminth. Characterized by an allergic syndrome in the early phase of the disease and dysfunction of the gastrointestinal tract - in the late. Selection of antimicrobial drugs. Drugs of choice: Pyrantel, 10 mg / kg once. Alternative drugs: levamisole, mebendazole, albendazole. ANKILOSTOMIDOSIS Ankilostomidoz -
  5. Roundworms.
    Roundworms. Morphology and anatomy. Some features of nutrition and metabolism of nematodes. Reproduction and life cycles. Parasitic roundworms are the causative agents of many dangerous diseases (nematodoses) of humans and domestic animals. The economic damage caused by nematodes in agriculture is very great. They also pose a serious threat to human health. Nematodoses Ascariasis
  6. Chronic post-hemorrhagic anemia
    It develops as a result of long-lasting non-abundant bleeding. Chronic post-hemorrhagic anemia in children is the main cause of iron deficiency. The following pathological conditions can be the causes of repeated small blood loss: 1. Diseases of the gastrointestinal tract: erosive and ulcerative lesions of the gastrointestinal tract, polyposis, diaphragmatic hernia, mucous membrane duplication,
  7. Mebendazole
    It has structural similarity with levamisole, but has a slightly wider spectrum of activity. Mechanism of action The antihelminthic effect is caused by a violation of cell tubulin synthesis, glucose utilization and inhibition of ATP formation. Spectrum of Ascaris, pinworms, hookworms, whipworm, trichinae and a number of other nematodes. Larval stages of some cestodes (echinococcus,
  8. General characteristics of basophils, their role in pathological processes
    Basophils account for 0-1% in leukocyte formula. They, like eosinophils, perform a detoxification function. The primary granules of basophils are large, surrounded by a membrane identical to the plasma membrane. The granule membrane, like the basophil plasma membrane, has a high phospholipase and lipoxygenase activity, therefore basophils are an important source of leukotrienes (leukotriene
  9. Pyrantel pamoat
    Pyrimidine derivative. Active only in relation to round worms. The mechanism of action of Pyrantel pamoat acts against worms as a depolarizing muscle relaxant, causing the development of neuromuscular blockade. Spectrum of Ascaris, pinworms, hookworms and some other nematodes. Pharmacokinetics Poorly absorbed in the digestive tract. Excreted mainly with feces (less than
  10. Construction of reservoirs, canals and other hydraulic structures
    The creation of reservoirs for various purposes (including those associated with canals) has become increasingly widespread throughout the world over the past decade. In this connection, there arises the need for a comprehensive study of the effects of reservoirs on the change in the circulation of pathogens of a number of helminths, intestinal protozoa, in particular diphyllobotriosis, opisthorchiasis, and giardiasis, to develop a scientific
  11. Introduction
    The urgency of the problem of helminth infections is associated with their widespread occurrence, the variety of negative effects on the human body and the pronounced polymorphism of clinical manifestations that impede the differential diagnosis of diseases, the lack of sterile immunity and specific methods of prevention. There are up to 300 species of helminths in the world, most of them are races in countries with
  12. Helminthiasis
    Helminth infections are a group of diseases caused by parasitic worms - helminths. In humans, more than 250 species of helminths are described, of which in Russia representatives of the class of roundworms are of the greatest importance: pathogens of ascariasis, ankilostomidoz, trichinosis, enterobiosis; trichuriasis; class of tapeworms: teniasis, diphyllobothriasis, echinococcosis; class flukes:
  13. Epidemiological significance of the soil
    As already mentioned, the soil is a natural receiver of solid and liquid wastes of humans and animals, which may be causative agents of various diseases. Fortunately, the majority of pathogenic microorganisms trapped in clean, unpolluted soil, more or less quickly die. In the soil contaminated with organic substances, they are able to maintain
  14. IMMUNITY FOR PARASITIC DISEASES
    John R. David (John R. David) Over the past decade, interest in human parasitic diseases and new approaches in combating them has steadily increased. One reason for this was the sheer scale of the problem. Over a billion people in the world are affected by parasitic diseases. Although obtaining accurate statistics is difficult, it is estimated that more than 200 million people are sick.
  15. Vizer V.A. Lectures on therapy, 2011
    On the subject - almost completely cover the difficulties in the course of hospital therapy, issues of diagnosis, treatment, according to the presentation, concise and quite accessible. Allergic diseases of the lungs Diseases of the joints Reiter's disease Sjogren's disease Bronchial asthma Bronchoectatic disease Hypertensive heart disease Glomerulonephrasafasditis Esophageal hernia Destructive lung diseases
  16. ALLERGIC LUNG DISEASES
    In recent decades there has been a significant increase in the number. patients with allergic diseases of the bronchopulmonary apparatus. Allergic lung diseases include exogenous allergic alveolitis, pulmonary eosinophilia, medicinal
  17. Exogenous allergic alveolites
    Exogenous allergic alveolitis (synonym: hypersensitive pneumonitis, interstitial granulomatous alveolitis) is a group of diseases caused by intense and, rarely, prolonged inhalation of antigens of organic and inorganic dusts and are diffuse, unlike pulmonary eosinophilia, and alveolar and interstitial structures. The emergence of this group
  18. TREATMENT
    1. General measures aimed at separating the patient with the source of antigen: compliance with sanitary requirements at the workplace, technological improvement of industrial and agricultural production, rational employment of patients. 2. Drug treatment. In the acute stage - prednisone 1 mg / kg per day for 1-3 days, followed by a decrease in dose
  19. CHRONIC EOSINOPHIL PNEUMONIA
    It differs from Leffler syndrome by a longer (more than 4 weeks) and severe course, up to severe intoxication, fever, weight loss, the appearance of pleural effusion with a high content of eosinophils (Lehrer-Kindberg syndrome). A long course of pulmonary eosinophilia, as a rule, is the result of a short-term, thorough examination of the patient in order to identify its cause. In addition to the reasons
