Classification of parasites and worms living in the human body

a worm from the human body

It is healthy to live in the world - parasites in the body interfere with this. These are lower plant and animal forms that live to the detriment of the owner. Translated from Greek, it means - free loader.

Through parasitism, they can be external and internal.

Parasites living in the human body are divided into flat and round worms.

Straight ones are divided into trematodes and cystodes.

Roundworms are also called nematodes.

Nematodes that live in the human body

worm parasite from the human body

Which parasites live in the body, primarily nematodes - reach great length and have the shape of a worm, hence the name - roundworms, they are:

  • roundworm;
  • pinworms;
  • blows;
  • Trichinella.

Roundworm

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

Signs of infection: nausea, salivation, loss of appetite. In the presence of a large number of ascarias, serious consequences can occur, rupture of postoperative sutures, 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, infect mostly children, more often in kindergartens. A sick person becomes the cause of the infection, and if the rules of personal hygiene are not followed, the possibility of infection increases significantly. Signs of worms:

  • nocturnal itching of the anal area;
  • reduced performance;
  • sleep disorders;
  • nervous disorders.

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

Hookworm

The parasite of 20 mm has a pink color, gives less manifestations, but the damage from it is huge. His oral cavity has teeth and plaques with which he gnaws blood vessels. The larvae penetrate the body through the skin of barefoot walkers.

The main task of the larvae is to enter the human mouth, from where, swallowing saliva, they descend into the intestines, where adult helminths are excreted. They feed on human blood, resulting in anemia. The threat is posed by their waste products that 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

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

The most common signs of infection are:

  • increase in blood test of eosinophilic leukocytes;
  • temperature rise to 40 ° C;
  • muscle pain;
  • conjunctivitis and facial swelling.

Trematode parasites

The helminths, which are small in size, have a flat body on which are 2 suction cups. Most of them are hermaphrodites. Development requires a temporary host.

Fluke

Helminth - hermaphrodite, grows up to 14 mm, affects the bile ducts. After entering the water bodies, the eggs settle in mollusks, where they develop into larvae, and then the larvae settle on fish shells. If a person eats lightly fried fish at this time, then he can become infected with this parasite.

In the body of its final host, the human, the fluke enters the duodenum, where the larva grows to an adult helminth. Water bodies are infected with flukes by people who eat fish products and work on water boats (their waste products penetrate the water).

Schistosomes

Helminths, which have heterosexual individuals, look like needles. One pair of parasites produces up to 3, 000 eggs in 24 hours. A person becomes infected while bathing or contaminated with water. In the lungs and blood vessels, the larva becomes an adult. This is followed by the laying of eggs in the intestines.

In the presence of schistosomes, the following is observed:

  • abdominal pain;
  • violation of appetite;
  • anemia;
  • change from diarrhea to constipation;
  • weight loss;
  • menstrual irregularities in women;
  • impotence in men;
  • reduced school achievement in children.

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

Where helminths can settle

Often people wonder where parasites live in the human body?

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

The human body, in which the parasite lives, becomes weakened and begins to suffer from various diseases, so how to determine that the parasites live in the body is not difficult at all. You just need to be more careful with yourself and if the slightest suspicion arises, you cannot postpone a visit to the doctor.

helminth in the human body

In order for the body inhabited by the 6-letter parasite to heal and become healthy, it must adhere to hygiene rules, not drink raw water and not eat poorly cooked meat. Only then can the risk of infection be reduced.

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. Finally, every other 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 destiny is part of the weak.
