Classification of parasites and worms living in the human body

Worm from the human body

It is healthy to live in the world - parasites in the body interfere with this. These are the lower plant and animal forms that live at the owner's expense. Translated from Greek, they mean - free riders.

Through parasitism, they can be external and internal.

Parasites living in the human body are divided into flatworms and roundworms.

Flat are in turn divided into trematodes and cystodes.

Roundworms are also called nematodes.

Nematodes living in the human body

Worm parasite from the human body

What parasites live in the body, especially nematodes - they reach a great length and have the shape of an earthworm, hence the name - roundworms, they are:

  • Roundworm;
  • Pinworms;
  • Hookworms;
  • Trichinella.

roundworm

One of the most common nematodes is a parasite, which in some cases reaches 45 cm. The female produces 200, 000 eggs, and this process occurs regardless of the presence of a male in the host's body. Together with the feces, the eggs fall into the ground, where, with favorable factors, they turn into larvae. You can get infected with this helminth through dirty hands and unwashed vegetables, fruits, berries.

Signs of infection: nausea, drooling, loss of appetite. With a large number of Ascaris, serious consequences can occur, the tearing of postoperative sutures, the appearance of pancreatitis. Roundworms are especially dangerous for pregnant women - their penetration into the fetus is possible.

Pinworms

Small worms up to 10 mm in size are mainly infected with them by children, more often in kindergartens. A sick person becomes the cause of infection, and if the rules of personal hygiene are not followed, the possibility of infection increases significantly. Signs of the appearance of worms:

  • nocturnal itching in the anal area;
  • decreased performance;
  • Sleep disorders;
  • nervous disorders.

The presence of pinworms does not threaten the patient's life, but it is quite uncomfortable and causes dysbiosis.

Hookworm

The 20 mm parasite is pink in color, shows fewer manifestations, but the damage is enormous. Its oral cavity has teeth and plates with which it gnaws its way through blood vessels. The larvae enter the body through the skin of barefooters.

The main task of larvae is to enter the human mouth, from where, when swallowing saliva, they descend into the intestines, where adult helminths are excreted. They feed on human blood, which leads to anemia. The danger comes from their waste products, which poison the body. Signs of the presence of helminths are: persistent bronchitis, dermatitis, nausea, abdominal pain, indigestion. The heart suffers from this parasite - myocarditis can occur.

Trichinella

The females of the worms are up to 4 mm in size, the males are smaller. They die in the external environment and are only viable in the body. The source of infection is uncooked animal meat. The parasites spread through the blood vessels in all organs, take root and can live peacefully for 20 years.

Trichinella worm from the human body

The most common signs of infection are:

  • an increase in the blood test of eosinophils;
  • a temperature increase to 40 ° C;
  • Muscle pain;
  • Conjunctivitis and facial swelling.

Trematode Parasites

Helminths that are small have a flat body that has 2 suction cups on it. Most of them are hermaphrodites. An intermediate host is required for development.

fluke

Helminth - hermaphrodite, grows up to 14 mm, affects the bile ducts. After entering the waters, the eggs settle in molluscs, where they develop into larvae, then the larvae settle on the fish scales. If a person eats badly fried fish at this moment, they can become infected with this parasite.

In the body of its ultimate host, a human, the leech is introduced into the duodenum, where the larva grows into an adult helminth. Waters are infected with leeches (their waste products enter the water) from people who eat fish products and work on watercraft.

Schistosomes

Helminths with heterosexual individuals resembling needles in appearance. A pair of parasites produces up to 3000 eggs in 24 hours. A person becomes infected while bathing or with contaminated water. The larva grows up in the lungs and blood vessels. Then the eggs are laid in the intestine.

In the presence of schistosomes, the following is observed:

  • Stomach pain;
  • violation of appetite;
  • Anemia;
  • Change from diarrhea to constipation;
  • Weight loss;
  • Violation of the cycle in women;
  • Impotence in men;
  • decreased school performance in children.

When introduced into nerve fibers, the development of paralysis, brain damage is possible.

Where can helminths settle

Often people are interested in where parasites live in the human body?

The localization is due to the type of host that entered the body of the "parasite". More often they settle in the digestive organs, in the lungs, in the heart, in the liver.

The human body in which the parasite lives is weakened and suffers from various diseases. So it is not difficult to determine if there are parasites living in the body. You just need to be more attentive to yourself and if the slightest suspicion arises, then you can not postpone a visit to the doctor.

Helminth in the human body

In order for the body in which the 6-letter parasite lives to heal and become healthy, it must adhere to the rules of hygiene, not drink raw water and not eat poorly cooked meat. This is the only way to reduce the risk of infection.

It's great to live in this world and you don't want to think about parasites in the human body, but you have to. After all, every second person on earth becomes infected with worms. The organism in which the parasite lives is a field of miracles that will happen. But trust in fate is the fate of the weak.
