Ascaridosis.

The causative agent is roundworm.

The transmission path is feck-op. Anthroponosis, geohelmintosis - for the maturation of eggs, their stay in the soil at 24 ° C is necessary.

Pathogenesis.

Eggs enter the intestine, larvae are released from them, which enter the portal vein through the wall of the intestine, then into the liver (by the 5th day). By the 10th day - hematogenously into the lungs, where they molt 2 times, break through the wall of the alveoli and through the respiratory tract enter the oropharynx, where they are swallowed and again enter the intestine (day 15). Shedding 2 more times - become sexually mature. 10-12 weeks after the invasion, eggs are laid. During migration - intoxication and sensitization by the products of the exchange of larvae.

The clinical picture.

With invasion - cm intoxication.

In the liver - pain, heaviness in the right hypochondrium, hepatomegaly.

In the lungs — Leffler’s family — a cough, dry or with sputum, spasm of blood, an asthmatic comp, shortness of breath, chest pain, wheezing, with Rg - “volatile infiltrates” that change configuration and localization.

In the blood - eosinophilia.

In the intestinal phase - dyspepsia, malabsorption.

Complications

Where roundworms get there, there will be a complication - acute appendicitis, hepatic colic, obstructive jaundice, pancreatitis, obstruction, perforation.

Diagnosis - detection of eggs in feces, larvae in sputum.

Treatment.

The early phase is mebendazole (100 mg / 2 p / day for 4 days), thiabendazole (50 mg / kg / 2 p / day for 5-7 days).

Intestinal phase - decaris (levamisole) 150 mg once, pyrantel (10 mg / kg), medamine (10 mg / kg), piperazine (1g / 3r / day for 2 days).

Ascaridosis.

  1. Ascariasis
    The causative agent is roundworm, parasitic in the adult stage in the small intestine. Ascaris life expectancy is about a year. At the stage of migration (the first 6-8 weeks after infection), Ascaris larvae exert a mechanical and sensitizing effect, causing eosinophilic infiltrates in the tissues of various organs and causing hemorrhages. In the intestinal phase (8 weeks after the lesion), adult roundworms
  2. Ascariasis
    The disease is caused by a nematode parasitizing in the small intestine of the intestines of chickens, turkeys, guinea fowl, sometimes geese and ducks. The causative agent of ascariasis is a fairly large parasite of a yellowish-white color. It has a spindle-shaped body, the length of which is 3-12 cm. Their eggs are oval in shape, 0.08 mm long and 0.05 mm wide. The development of roundworm occurs without the participation of an intermediate host. Fertilized Female
  3. Parasitic diseases in children (enterobiosis, ascariasis)
    Of all the registered parasitoses in people in the republic, enterobiosis, ascariasis are the most significant. Enterobiosis - helminthiasis, challenge. round pinworm. Etiology and epidemiology. Pinworm - a small white nematode parasitic in the human intestines. Helminth life expectancy is from 1 to 3 months; at the end of life, the female helminth creeps out and postpones
  4. Epizootological data
    Cattle: 1. fasciosis - infection 30%; 2. dictiocauliasis - 25%; 3. telaziosis - 100%; MRS: 1. fasciosis - 20%; 2. fleas - 50% 3. lice - 40% 4. ticks - 10% Pigs: 1. esophagostomiasis - 30% 2. metastrongylosis - 20% 3. ascariasis - 60% Horses: 1. oxyurosis - 20% 2. ascariasis - 30% 3.strongilatoses -
  5. Helminthiasis
    Helminthiasis is a group of diseases caused by parasitic worms - helminths. Over 250 types of helminths have been described in humans, of which in Russia representatives of the class of roundworms are of greatest importance: causative agents of ascariasis, hookworm infections, trichinosis, enterobiasis; trichocephalosis; class of tapeworms: teniosis, diphyllobothriasis, echinococcosis; class of flukes:
  6. Geohelminthiasis
    Ascaridosis - caused by roundworm parasitizing in the small intestine of a person. These are round worms with pointed ends. The body length of the female is 25–40 cm, the male is 15–20 cm. The only source of causative agents of ascariasis is a sick person. A roundworm female lays up to 200-240 thousand immature eggs per day (their size is 0.06 x 0.04 mm), which enter the environment with human feces. Eggs

  8. NEMATODOSES
    Ascaridosis Ascaridosis is a human helminthiasis caused by round helminth Ascaris lumbricoides. It is characterized by an allergic syndrome in the early phase of the disease and a violation of the gastrointestinal tract in the late phase. Choice of antimicrobial agents. Drugs of choice: pyrantel, 10 mg / kg once. Alternative drugs: levamisole, mebendazole, albendazole. ANKILOSTOMIDOSIS Ankylostomidosis -
  9. Levamisole
    It is characterized by a narrow spectrum of activity. Acts only on some round helminths. It is one of the drugs of choice for the treatment of ascariasis. The mechanism of action The anthelmintic effect is due to a violation of the bio-energy of helminths and a paralyzing effect. The spectrum of activity of roundworm, pinworms and some other nematodes. Pharmacokinetics is well and rapidly absorbed in
  10. Dispersion and circulation of parasitosis pathogens in the environment
    Helminth eggs and larvae The main "suppliers" (sources) of helminth eggs to the environment are sick people, domestic and wild animals, and birds. The power of the source of invasion, and therefore the amount of invasive material released into the environment, depends on the type of invasion, fecundity, number and life of helminths. It has been established that a female roundworm excretes about
  11. Urbanization
    Urbanization is the process of concentration of industry and population in large cities. The population from the private sector moves to comfortable apartments in multi-storey buildings (only in 1984, 113.7 million m2 of living space was commissioned in our country, which improved housing conditions for more than 10 million people). This eliminates personal plots, the soil of which is often

    Roundworms. Morphology and anatomy. Some features of the nutrition and metabolism of nematodes. Reproduction and life cycles. Parasitic roundworms are causative agents of many dangerous diseases (nematodes) in humans and domestic animals. The economic damage caused by nematodes in agriculture is very large. They pose a serious threat to human health. Nematodoses. Ascariasis
  13. Differential diagnosis
    The above-mentioned tissue helminthiases must be differentiated from each other, and in some cases (toxocariasis, trichinosis) - with the acute phase of other helminthiases (ascariasis, schistosomiasis, opisthorchiasis) and diseases, including allergic nature, accompanied by high eosinophilia. Toxocariasis, depending on the prevailing organ changes, differentiates with bronchial asthma,
