Ascaris is a dangerous worm that can parasitize in the human body and harm its health. Ascaris eggs cause ascariasis, a common disease that is diagnosed in both children and adults. Is it possible to protect yourself from roundworm and how to do it correctly? You will find the answer to this question in our article.


Why are roundworm eggs dangerous?

Description with photos

What do Ascaris eggs look like and what is inside them? In the photo, ascaris eggs seem small and invisible. It really is. It is impossible to see the eggs of the human roundworm with the naked eye. Photos of roundworm eggs indicate that they come in different shapes and sizes.

The cell center in the roundworm egg contains an oval-shaped nucleus. This is important, since mitosis is the basis of the principle of reproduction of this parasite. Mitosis in the roundworm egg is a type of indirect cell division. If you want to study all the stages of mitosis, use the cleaving roundworm egg. A large number of dividing cells can be found in it.

Take a look at the photo of the roundworm egg:

Transmission routes

Ascaris eggs ripen in the soil. They can enter the human body either through contact with the ground, or indirectly, that is, through the objects in it.

Infection occurs after ingestion of eggs. This most often occurs when eating unwashed foods. A child can get ascariasis after playing in the sandbox and licking dirty toys.

Parasitism and reproduction

The development of larvae from eggs laid by roundworms occurs directly in the human body. Once in the intestine, the larva throws off the egg shells and dissolves them by secreting its own enzymes. The parasites that hatch from the eggs are pinkish or reddish round worms.

The development of larvae from eggs laid by roundworms occurs at a temperature of 37 ° C. The larva enters the maturation phase 8-15 days after entering the intestine. Its total life span in the human body is one year.

Constant reproduction is an essential condition for the life of an adult parasite. The fragmentation of the roundworm ovum occurs in the uterine cavity. 240,000 - how many eggs a female roundworm lays daily. All of them are excreted into the external environment along with feces.

Symptoms of presence in the body


Ascaris infection symptoms

The first symptoms of ascaris infection appear 1-2 months after the eggs enter the intestines. It is important to understand that in some people, the early stage of parasite development in the body is not accompanied by pronounced symptoms. However, in most cases, the infected have:

  • headaches;
  • weakness in the body;
  • fast fatiguability;
  • heat;
  • allergic reactions including itching and rash.

Sometimes the infection is accompanied by pulmonary disorders. It can be:

  • intense pain in the chest area;
  • cough;
  • sputum production;
  • shortness of breath.

Pulmonary disorders when infected with roundworm

The late stage of the disease is extremely rare without symptoms. Many infected people complain about:

  • problems with gastrointestinal function;
  • pain in the abdomen and right hypochondrium;
  • nausea;
  • chest discomfort;
  • asthenic condition;
  • disorders of the nervous system;
  • drastic weight loss.


How is the diagnosis carried out and is it possible to identify the disorder on your own using a photo of roundworm eggs in the feces?

About the look of Ascaris eggs in the feces, known only by professionals, as they are only visible under a microscope. For this reason, it makes no sense to search the Internet for photos of Ascaris eggs in feces. If you find symptoms of parasite infection, you should immediately seek diagnostics.


Ascaris eggs under a microscope

To diagnose ascariasis in modern medicine, several methods are used at once. If the doctor suspects the patient has an intestinal form of the disease, then he asks him to pass the feces for analysis. Photos of roundworm eggs in feces under a microscope do not look very pleasant, so in this article we will do without them.

Ascaris eggs in feces can be fertilized and unfertilized. The presence of fertilized ascaris eggs in the feces suggests that both males and females live in the human body. This is dangerous for others, since after leaving the intestines, the fertilized eggs fall into the soil. When unfertilized ascaris eggs are found, a person does not pose a danger in terms of infection, but it still requires treatment.

For diagnostics, the ELISA method is also used, or, as it is also called, enzyme immunoassay. With the development of the pulmonary form of ascariasis, doctors find parasite larvae in the sputum of patients.


To drive the parasites out of the body, the doctor prescribes anthelmintic drugs to his patient. They are highly effective at all stages of the development of pathology, however, they have certain contraindications and side effects. In some cases, surgical intervention is prescribed.


Anthelmintic drugs

The lack of timely treatment entails serious consequences. It can be intestinal obstruction, asphyxia, jaundice and even acute pancreatitis. To avoid all this, it is enough to make an appointment for a diagnosis in time and undergo the treatment prescribed by a specialist. The effectiveness of therapy can be easily determined by examining the stool.


Ascaris eggs are a great danger to humans. Fortunately, it is possible to eliminate the risk of infection with them. To do this, it is enough to follow simple recommendations:

  • wash your hands thoroughly before eating;
  • rinse greens, vegetables, fruits and berries before eating them;
  • do not allow the child to lick dirty toys, as well as closely monitor him on the street (for parents);
  • take prophylactic anthelmintic drugs (for people who live in an environment of widespread parasites).
