The causative agent is ascaris.
The transmission path is fec-or. Anthroponosis, geogelmintosis - for the maturation of eggs, their stay in the soil is necessary at 24 ° C.
Eggs enter the intestine, from which larvae are removed, which through the wall of the intestine enter the portal vein, 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 swallow and re-enter the intestine (day 15). They molt 2 more times - they become sexually mature. After 10-12 weeks after the invasion lay eggs. During migration - intoxication and sensitization by products of larval exchange.
When infecting - with-m intoxication.
In the liver - pain, heaviness in the right hypochondrium, hepatomegaly.
In the lungs - with Leffler - coughing dry or with scant sputum, blood admixture, asthmatic comp, dyspnea, chest pain, wheezing, with Rg - "flying infiltrates", changing configuration and localization.
In the blood - eosinophilia.
In the intestinal phase - dyspepsia, malabsorption.
Where the ascarids get, there will be a complication - acute appendicitis, hepatic colic, jaundice obturator, pancreatitis, obstruction, perforation.
Diagnosis - the detection of eggs in feces, larvae in sputum.
The early phase is mebendazole (100 mg / 2p / day for 4 days), thiabendazole (50 mg / kg / 2p / day at 5-7 days).
Intestinal phase - decaris (levamisole) 150 mg once, pyrantel (10 mg / kg), medamine (10 mg / kg), piperazine (1g / 3p / day for 2 days).

The causative agent is ascaris, which parasitizes in the adult stage in the small intestine. Life expectancy of ascarids is about a year. In the migration stage (the first 6-8 weeks after infection), the ascarid larvae have a mechanical and sensitizing effect, causing eosinophilic infiltrates in the tissues of various organs and causing hemorrhages. In the intestinal phase (8 weeks after injury) adult roundworms
The disease is caused by a nematode parasitizing in the small intestine 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 ascarids occurs without the participation of an intermediate host. Fertilized female

Of all the registered parasitosis in humans on the territory of the republic, enterobiosis and ascariasis are among the most significant. Enterobiosis - helminthiasis, causing. round helminth pinpoint. Etiology and epidemiology. Pinworm is a small nematode of white color parasitizing in the human intestine. The life expectancy of the helminth is from 1 to 3 months, at the end of life the female helminth crawls out and lays off

Cattle: 1. fasciosis - infection of 30%; 2. Dictyocaulosis - 25%; 3. Telasiosis - 100%; MRS: 1. fasciosis - 20%; 2. fleas - 50% 3. lice - 40% 4. mites - 10% Pigs: 1. esophagostomy - 30% 2. metastronitis - 20% 3. ascariasis - 60% Horses: 1. oxyurosis - 20% 2. ascariasis - 30% 3. Strongylatoses -
Helminthiasis is a group of diseases caused by parasitic worms-helminths. In humans, more than 250 species of helminths are described, among them the representatives of the class of roundworms are most important in Russia: causative agents of ascariasis, ankylostomiasis, trichinosis, enterobiosis; trichocephalosis; class of tapeworms: shinose, diphyllobothriasis, echinococcosis; class flukes:
Ascaridosis - is caused by ascarids parasitizing the human small intestine. These are round worms with pointed tips. The body length of the female is 25-40 cm, the male - 15-20 cm. The only source of pathogens of ascariasis is a sick person. The female of the roundworm lays up to 200-240 thousand immature eggs per day (their size is 0.06 x 0.04 mm), which, with their feces, fall into the environment. Eggs

ASKARIDOZ Ascariasis is a human helminthiasis caused by the round helminth Ascaris lumbricoides. It is characterized by an allergic syndrome in the early phase of the disease and a violation of the functions of the gastrointestinal tract - in the late phase. Choice of antimicrobial drugs The drugs of choice: pyrantel, 10 mg / kg once. Alternative drugs: levamisole, mebendazole, albendazole. ANKILOSTOMIDOZ Ankylostomidosis -
Characterized by a narrow spectrum of activity. Valid only for some round helminths. It is one of the drugs of choice for the treatment of ascaridosis. Mechanism of action The anthelmintic effect is caused by the disturbance of the bioenergetics of the helminths and the paralyzing action. Spectrum of activity Ascaris, pinworm and some other nematodes. Pharmacokinetics Well and quickly absorbed into
- Dissipation and circulation of parasitic pathogens in the environment
Eggs and larvae of helminths The main "suppliers" (sources) of helminth eggs to the environment are sick people, domestic and wild animals, birds. The power of the source of invasion, and consequently, the amount of invasive material released into the environment, depends on the type of invasion, fecundity, number and life span of helminths. It is established that the female roundworm
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 houses (only in 1984, 113.7 million m2 of living space were put into operation in our country, which helped improve the living conditions of more than 10 million people). At the same time homestead plots are being eliminated, the soil of which is often

- Differential diagnostics
The above tissue helminthiases must be differentiated between themselves, and in a number of cases (toxocarosis, trichinosis) with an acute phase of other helminthiases (ascaridosis, schistosomiasis, opisthorchiasis) and diseases, including allergic nature, accompanied by high eosinophilia. Toxocarosis, depending on the prevailing organ changes, is differentiated with bronchial asthma,
