A multicellular representative of the ascaris ecosystem, it can inhabit the human body for about 12 years. It is people who are the first and final hosts of the parasite.
At the next stage of infection, ascaris eggs end up in the human mouth and reach the intestines. Here larvae already appear, which undergo their first migration. Making a lumen in the intestinal wall, they first move through the circulatory system to the region of the liver, bile ducts. Rarely - the pancreas.
The next stage is the heart and bronchi. Causing irritation of the respiratory system, roundworms, along with a cough, again end up in the human body. But this time, they remain in the small intestine until maturity and reproduction.

Development cycle or how roundworm eggs appear
For the process of fertilization and the birth of future roundworms to take place, two sexually mature representatives of the human roundworm are needed: a female and a male. The male individual, the length of which ranges from 15 cm to 25 cm, has a set of sex differences.
The male has a testis, a vas deferens. The female is larger than the male. Can be up to 40 cm in length. The female also has sexual characteristics: 2 ovaries, oviducts, several combined uterus and vaginas. The reproductive system ends with a hole in the abdominal cavity.
The next stage of development begins after the egg enters the body of the final host, in the gastrointestinal tract. Here the larva appears and sheds the shell.
After going through the process of human infection through the liver, bloodstream, cardiovascular, respiratory system, it is localized in the small intestine and reaches maturity. And then it multiplies again, the cycle starts over.
Human roundworm eggs
The result of mating of opposite-sex representatives of parasites are roundworm eggs, which the female lays daily. There are quite a lot of them, about 240-250 thousand. But this does not mean that all of them are suitable for further development.
In some cases, when there are no male roundworms in the small intestine, the females carry unfertilized eggs. They are oval oblong cells that have a thin membrane and a yolk substance inside.
The oval shape testifies to the fact that future offspring will appear from the ascaris egg.
Protects the larva, which is inside, a shell, consisting of several layers:
- outer. Protein, the strongest and densest. Its absence is sometimes observed;
- protective. Consists of three layers that prevent mechanical damage;
- interior. Contains nutrients and essential fluids for further development.
How the embryos of the future parasite, the roundworm eggs, may look like, can only be seen through a special magnifying device within the laboratory. Its average length is about 0.07 mm.
At temperatures from + 10 ° C to 35 ° C, high humidity, they can live up to 10 years. They die only at low temperatures: at -27 ° C after a few days. And even when the temperature reaches -50 ° C, they can exist for another 24 hours.
Infection with Ascaris eggs
Most often, diseases associated with parasites are observed and diagnosed in the warm season, as well as in summer. It all depends on weather conditions and on the terrain where the embryos of future worms fall. How do eggs penetrate a person?
Reasons for infection:
- water. Poorly equipped treatment facilities, from which already contaminated liquid enters the sewage system, for agricultural needs. Fresh water from the pond;
- untreated greens, vegetables, fruits, berries;
- insects. They are temporary hosts and carriers, as they often interact with contaminated soil. Ascaris eggs in the feces, to which ants, flies, beetles touch, attach to the legs and continue their life cycle;
- person. The embryos of future parasites stick to shoes and enter living quarters;
- common items that have been touched by people with helminthic infestation;
- dust. Can be absorbed through inhaled air;
- leather. This also includes the area under the nails. Ascaris larvae after 12 days form inside the egg, not reaching the human intestine;
- less often fish becomes a source of infection, which swallows parasite microorganisms and animals together with water.
Analysis for eggs, worms and roundworms
In the early stages, worms can only be identified by diagnosis. It can take from 1 month before the first characteristic signs appear. It is during this period that the growth and maturation of the roundworm individual occurs.
Therefore, it is necessary to regularly undergo a complete medical examination and be tested for parasites:
- traditional analysis for eggs of the worm. The material is collected at home. Placed in a special container and handed over to laboratory staff. Repeated several times;
- study of the chemical composition of blood. Particular attention is paid to changes in erythrocytes, leukocytes, a decrease in hemoglobin levels;
- radiography, ultrasound. Determine the localization or consequences of parasites according to the state of organ damage;
- enzyme immunoassay for IgE and IgG antibodies. It is produced by introducing a special composition. It stains the formed antigens, which are a reaction to foreign cells;
- agglutination reaction. Study of blood serum and detection of antibodies in it that are produced against foreign microorganisms;
- the study of sputum. The presence of helminthic invasion is evidenced by the exceeded rates of eosinophils, as well as the larvae of Ascaris lumbricoides or roundworm found;
- vegetative resonance testing. Computer diagnostics has a large error, but it allows early detection of changes that cause roundworms by their vital activity in the human body. The accuracy of the data when using this method is no more than 87%.
With neglect and untimely treatment of symptoms of the disease to a doctor, there is a chance of seeing an adult. They can pass through the stool or through the anus, causing itching or burning.
How to remove a roundworm egg
If the diagnosis confirms that parasites are the cause of the deterioration in health, it is necessary to start urgent treatment.
It should be borne in mind that it is easier to get rid of adults than to eliminate the results of their reproduction. How to remove a representative of the human roundworm, as well as its eggs from the body.
In this case, doctors prescribe compulsory drug treatment:
- Pirantel. The drug affects both eggs and adults of the parasite. Reception is single. The daily dose is 10 mg per 1 kg of adult weight. Repeat after 3 weeks for prophylaxis;
- "Mintezol". An antihelminthic agent that inhibits adult roundworms and inhibits the development and vital activity of eggs and larvae. The course of treatment is 1-2 days. The daily dose is based on 25 mg of the composition per 1 kg of body weight;
- "Vermox". Accepted even with mixed manifestations of helminthiasis. The treatment period is about 3 days. The recommended dose is 1 tablet 2 times a day.
Depending on the localization, it complements the treatment with Metaclopramide, which helps to improve and restore the intestines, the Enterosgel sorbent, antiallergic drugs like Suprastin, expectorants.
Prevention of the appearance of roundworm eggs in the human body
To protect yourself and your family from possible helminthic invasions and concomitant diseases that they cause, you need to take care of your health:
- compulsory medical examination 2 times a year;
- taking drugs for the prevention of worms: "Trichopol", "Dekaris";
- keeping the house clean;
- eating only processed foods and purified drinking water;
- the use of protective equipment, such as masks, gloves, in production, summer cottages;
- compliance with the rules of personal hygiene.
Any parasites are dangerous to humans. Don't forget about it. And in a neglected form, they also cause chronic lesions and serious illnesses, affect organs.
