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, which live at the expense of the owner. Translated from the Greek, they mean: freeloader.

Speaking of parasitism, they can be external and internal.

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

The flat ones are divided, in turn, into flukes and cystodes.

Roundworms are also called roundworms.

Roundworms that live in the human body

parasitic worm from the human body

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

  • ascarids;
  • pinworms;
  • hookworms;
  • trichina.

nematodes

One of the most common nematodes is a parasite, which in some cases reaches a size of 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, when favorable factors arise, they turn into larvae. You can get infected with this helminth through dirty hands and unwashed vegetables, fruits, berries.

Signs of infection: nausea, salivation, loss of appetite. In the presence of a large number of roundworms, serious consequences can occur, rupture of postoperative sutures, the onset of pancreatitis. Nematodes are especially dangerous for pregnant women: their penetration into the fetus is possible.

pinworms

Small worms, up to 10 mm in size, are infected mainly by children, most often in nurseries. 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:

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

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

hookworm

The 20 mm parasite has a pink color, gives less manifestations, but the resulting damage is colossal. Its oral cavity has teeth and plaques with which it gnaws blood vessels. The larvae enter the body through the skin of barefoot walkers.

The main task of the larvae is to enter the human mouth, from where, when swallowing saliva, they descend into the intestine, where adult helminths are expelled. They feed on human blood, causing anemia. The threat is their waste products, which poison the body. The signs of the presence of helminths are: persistent bronchitis, dermatitis, nausea, abdominal pain, digestive disorders. The heart suffers from this parasite - myocarditis may appear.

Trichinella

The females of the worms reach 4 mm, the males are smaller. They die in the external environment and are vital only within the body. The source of the infection is raw animal meat. Through the blood vessels, parasites are distributed 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 eosinophilic leukocytes;
  • an increase in temperature to 40 ° C;
  • muscular pain;
  • conjunctivitis and swelling of the face.

fluke parasites

The helminths, small in size, have a flat body, on which there are 2 suckers. Most of them are hermaphrodites. An intermediate host is required for development.

Fluke

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

In the body of its final host, a human, the fluke is introduced into the duodenum, where the larva becomes an adult helminth. Water bodies are infected with fluke from people who eat fish products and work on boats (their waste products get into the water).

schistosomes

Helminths, with heterosexual individuals, which resemble needles in their appearance. A pair of parasites produces up to 3000 eggs in 24 hours. A person becomes infected while taking a bath or with contaminated water. In the lungs and blood vessels, the larva becomes an adult. After this, egg laying takes place in the intestine.

In the presence of schistosomes, the following is observed:

  • stomach ache;
  • violation of appetite;
  • anemia;
  • go from diarrhea to constipation;
  • weight loss;
  • violation of the cycle in women;
  • impotence in men;
  • decreased academic 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 location is due to the type of host that has entered the body of the "parasite". Most often they are deposited in the digestive organs, lungs, heart, liver.

The human body, where the parasite lives, weakens and begins to suffer from various diseases, so how to determine that parasites live in the body is not at all difficult. You just need to be more attentive to yourself and if the slightest suspicions appear, you can not postpone a visit to the doctor.

helminths in the human body

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

It's good to live in this world and you don't want to think about parasites in the human body, but you have to. After all, one in two people on Earth gets infected with worms. The organism in which the parasite lives is a field of miracles, which will happen. But trusting in fate is the fate of the weak.
