Infestation with roundworms is more common than infection with other parasites. This is caused by violation of personal hygiene rules and consumption of dirty, thermally untreated foods.
Ascariasis is accompanied by a huge list of negative symptoms, which are often mistaken for other diseases - this is due to the migration of the parasite through the internal organs and systems of the body.
What to do in such a situation? To get started, we recommend reading this article. This article describes in detail methods of controlling parasites. We also recommend that you consult a specialist. Read the article >>>
Knowing what roundworms look like, it will be easier to choose effective means to combat them.
What roundworms look like: appearance and structure
Roundworms belong to a group of nematodes that live in the digestive system of mammals. There are several varieties of roundworm that can infect not only humans, but also various animals.
The worm is round in shape and the color is whitish-yellow or light pink. These are quite large individuals with a thickness of about 6 mm. Females can grow up to 40 cm in length, and males up to 25 cm.
Ascaris
Adult sexually mature individuals are distinguished by a curved body shape and a cone-shaped tail. The body of the helminth is completely covered with cuticles, which protect it from aggressive external factors.
An adult female can lay more than 200 thousand eggs per day.
Roundworms do not have special hooks with which they could attach to the intestinal walls. They independently move throughout the organ, in the opposite direction of the movement of nutrients.
During defecation, the parasite eggs are released. Adult worms can also be seen in feces - this occurs already at an advanced stage of infection.

are human parasites, roundworms, which, when infecting the body, most often settle in the lumen of the small intestine. Although they can choose other organs as their home - the liver, heart, brain, lungs, and use blood to migrate from one place to another. Roundworms are not fatal to humans, but they greatly reduce the quality of life and pollute the body with the products of their vital activity.
Roundworms are heterosexual parasites, and a healthy female can lay about 200,000 eggs per day. Ascaris eggs can be detected under a microscope - we will not attach photos to the article, as they are quite unpleasant. But often this study is not enough to make an accurate diagnosis. The fact is that only male individuals can live in the body, and in this case, roundworm eggs cannot be seen under a microscope - they simply will not be there.
How do you even understand that your body is infected with parasites? The symptoms are quite vague, so even doctors do not always quickly determine this. The most common symptoms: upset stool, nausea, fever, weakness, dry cough, nervousness. Agree, this is suitable for many different diseases. If you suspect a helminthic infestation, you must visit a doctor, conduct a comprehensive examination of the body and take the necessary medications (they are prescribed only by a doctor).
What does roundworm look like under a microscope? In fact, an adult can be seen with the naked eye - mature parasites can reach a length of 45 cm (usually 25–30 cm). Outwardly, they resemble ordinary worms, yellowish-white in color with a matte, opaque shell. But to identify parasite eggs, you already need a microscope, but not necessarily a professional one - a modest magnification of 10 times is enough. Ascaris eggs under a microscope (you can find photos on the Internet) look like oval (sometimes round) formations about 75–85 microns long and about 35–50 microns wide.
In our online store you will find a large selection of microscopes for performing a variety of tasks, including for conducting laboratory research and identifying parasitic infestations.

What do roundworm eggs look like?
Roundworm eggs ripen in the soil. Ascaris does not have intermediate hosts, so the development of eggs and their transformation into larvae will occur only when they enter the human digestive system. Roundworms are transmitted from person to person. The development of the parasite is possible only under the conditions of the human body, so most of the eggs that fall into the soil die.
Symptoms of roundworm infestation appear only at the migration stage, after the eggs transform into larvae.
The egg sizes are extremely small, no more than 0.07 mm. You can see the eggs only under a microscope. They have a round or oval shape and are covered with a protective shell.
| Layer | Description |
| Protein | The outer layer is brown. |
| Three-layer shell | It has a glossy surface and is extremely durable. It provides the egg with the necessary protection from environmental factors and mechanical damage. |
| Interior | It has a porous structure, provides the embryo with nutrients, water - everything that is required for the development of the fetus. |
To diagnose an infection, you need to undergo a medical examination and tests. Treatment is selected only after diagnosis.
It is not recommended to choose medications on your own - they are toxic to the body, and since worms also secrete toxins, self-medication can lead to irreparable consequences.

Treatment and prevention
It should be noted right away that the whole family should undergo treatment. Before starting treatment for ascariasis, it is necessary, along with examining stool, to also conduct hematological, immunological and x-ray studies.
Vegetative resonance testing is an effective diagnostic method for identifying the type of helminth infection, the area of localization of roundworms and the period of development of the disease.
First of all, it is necessary to prepare the body. For this, along with medications (allochol, enterosgel), traditional medicine (pumpkin oil, flaxseed oil) is used.
To destroy roundworms, drugs such as decaris, vormil, triad Evalar, pyrantel, etc. are used, the dosage of which is determined by the doctor.
The body must be cleansed of dead parasites, otherwise intoxication will occur. Cleansing is done using laxatives and cleansing enemas.
And finally, the completion of treatment will be taking medications to eliminate the consequences of helminth infestation: relieving inflammation, healing damaged walls of blood vessels and capillaries. To strengthen the immune system, immunomodulators are also prescribed.
To prevent ascariasis it is necessary:
- strictly adhere to hygiene requirements (be sure to wash your hands after using the toilet, before eating, after public transport, and for children after walking and playing in the fresh air);
- wash vegetables and fruits thoroughly;
- Do not leave food out in the open, as roundworms are carried by flies and cockroaches.
Pets, or more precisely, the fleas that parasitize them, are also carriers of roundworm eggs and larvae, so anthelmintic therapy is recommended for cats and dogs.
What do roundworm larvae look like?
For the formation of larvae, favorable conditions are required, such as the human intestine. When the eggs reach the intestines, the process of their development and transformation into larvae begins.
The larvae are microscopic in size (about 50 microns), have rounded ends, an oblong shape, and a pale pink color. Due to their structural features, they easily penetrate the intestinal mucosa, into the bloodstream and spread throughout the body.
At the end of the migratory stage (about 1 month), the larva again enters the intestine, it grows to a sexually mature individual and begins to actively reproduce. Due to self-infection, the infection progresses rapidly and develops to a chronic stage. If left untreated, the wearer may die.

What roundworms look like in the feces of a child and an adult
During defecation, dead males are excreted from the body along with feces and die after mating with the female. Dead individuals may be dark in color and difficult to see in feces due to their immobile state.
At the chronic stage of infection, large accumulations of roundworms are excreted along with the feces - dead, living individuals, and their eggs. Roundworm larvae usually migrate throughout the body, so it is extremely rare to find them in feces.
A living specimen is easy to see even without special equipment, since it is large in size and will move. The features of its appearance are no different from worms living in the body.
To reduce the likelihood of infection, you need to adhere to personal hygiene rules. If your health worsens, you should consult a doctor to determine the exact cause of your ailments.
Symptoms of roundworm infection may be similar to those of other diseases. Self-medication can significantly worsen the condition and lead to irreparable consequences.

From: Lyudmila S. ()

Not long ago my health condition worsened. I began to feel constant fatigue, headaches, laziness and some kind of endless apathy appeared. Problems also appeared with the gastrointestinal tract: bloating, diarrhea, pain and bad breath.
I thought it was because of the hard work and hoped that it would go away on its own. But every day I felt worse. The doctors couldn’t really say anything either. Everything seems to be normal, but I feel like my body is not healthy.
I decided to go to a private clinic. Here I was advised, in addition to general tests, to get tested for parasites. So in one of the tests they found parasites in me. According to doctors, these were worms, which 90% of people have and almost everyone is infected, to a greater or lesser extent.
I was prescribed a course of antiparasitic medications. But it didn’t give me any results. A week later, a friend sent me a link to an article where some parasitologist shared real tips on fighting parasites. This article literally saved my life. I followed all the advice that was there and after a couple of days I felt much better!
Digestion improved, headaches went away and the vital energy that I so lacked appeared. To be sure, I took the tests again and no parasites were found!
