Roundworms (Ascaris)

Roundworms (Ascaris): Parasites inside the human body

Roundworms (Ascaris) are a genus of parasitic nematodes that live in the human body. One of the most widespread roundworm species is A. lumbricoides, the largest nematode of this genus, with an adult female reaching up to 35 cm in length. These parasites live in the human intestines and can cause a variety of health problems.

Roundworms reproduce by laying eggs, which are then excreted in the feces of an infected person. Eggs can be transmitted from person to person through contaminated water or food. If the eggs are exposed to a favorable environment, they develop into larvae, which then migrate through the body.

Ascaris larvae undergo a complex migration path through human organs. They enter the intestine and then travel through the hepatic portal vein to the liver, heart, lungs, trachea, larynx and pharynx before returning back to the intestine where they develop into adults. In this process, a number of unpleasant symptoms and complications may occur, such as abdominal pain, cough, shortness of breath and throat irritation.

Ascariasis, caused by roundworm infection, is a common disease in some regions of the world, especially those where hygiene and sanitation are poor. Children are the most susceptible to this disease due to their increased susceptibility and lack of hygiene awareness.

To prevent roundworm infection, good sanitation and hygiene are essential. Regular hand washing before eating, drinking clean water and handling food should become a habit for everyone. It is also important to contact a medical professional if you suspect a roundworm infection to get an accurate diagnosis and appropriate treatment.

Overall, roundworms are nasty parasites that can be harmful to human health. However, by taking simple precautions and maintaining good hygiene, you can reduce the risk of infection and overcome this problem.

Roundworms (Ascaris): description, distribution and routes of infection

Roundworms (Ascaris) are a genus of parasitic nematodes that can live in the human intestines and cause various diseases. The most widespread species of roundworm, A. lumbricoides, is the largest representative of nematodes that parasitize the human intestine. The length of an adult female can reach 35 cm.

Ways of infection with roundworms

Ascaris eggs are excreted from the human body in feces and can contaminate soil, water and food. When contaminated foods are consumed, the eggs enter the human body, where roundworm larvae are hatched in the intestines. They then begin to migrate through the organs and tissues of the body, passing through the hepatic portal vein, liver, heart, lungs, trachea, larynx and pharynx before returning back to the intestines. Here the larvae and tracks develop into adults.

Diseases caused by roundworms

Roundworms can cause various diseases such as ascariasis. Symptoms of ascariasis may include abdominal pain, nausea, vomiting, diarrhea, and allergic reactions. In some cases, if the number of roundworms is large enough, they can cause intestinal obstruction or lung diseases such as bronchitis or pneumonia.

Treatment of ascariasis

Treatment for ascariasis includes the use of anthelmintics, drugs that kill parasites. It is important to remember that self-medication can be dangerous and lead to undesirable consequences. If you suspect a roundworm infection, you should consult a doctor to get a diagnosis and prescribe appropriate treatment.

conclusions

Roundworms are dangerous parasites that can cause serious illness. To avoid infection with roundworms, it is necessary to observe the rules of personal hygiene, avoid consuming contaminated food and water, and also carry out regular disinfection and cleaning of premises and household items. If you suspect a roundworm infection, you should consult a doctor to get a diagnosis and prescribe appropriate treatment.

Roundworms, or Ascaris, are a genus of parasitic nematodes that live in the human body. One of the most famous and widespread species of this genus, Ascaris lumbricoides, is the largest representative of nematodes living in the human intestine. An adult female Ascaris lumbricoides can reach a length of up to 35 cm.

Ascaris is transmitted through eggs that they lay in feces. These eggs can be transmitted from person to person through contaminated water or food. After entering the human body, roundworm eggs break through the intestinal walls and are excreted externally.

However, roundworms have a complex life cycle. Ascaris larvae go through several stages of development. After the larvae leave the intestine, they migrate through the hepatic portal vein, liver, heart, lungs, trachea, larynx and pharynx before they return back to the intestine. In the intestines they reach maturity and develop into adults.

Ascariasis caused by roundworms can lead to various symptoms such as abdominal pain, nausea, vomiting, eating disorders, and delayed physical development in children. In severe cases of roundworm infection, complications may occur due to the migration of larvae in organs and tissues.

To prevent ascariasis, it is recommended to practice good hygiene, including regular hand washing before eating and after using the toilet, drinking clean drinking water and thoroughly handling food before consumption.

Overall, roundworms (Ascaris) represent an important health and hygiene concern, and control of this infection plays an important role in maintaining the health and well-being of the population.
