Classification of parasites and worms living in the human body

worm from the human body

Healthy living in the world - parasites in the body interfere with this. These are the lower forms of plants and animals, living at the expense of the owner. Translated from the Greek, they will say - free cargo.

By way of parasitism, they can be external and internal.

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

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

Roundworms are also called nematodes.

Nematodes living in the human body

parasite of worms from the human body

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

  • round worm;
  • peg worms;
  • worms;
  • trichinella.

Round worm

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

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

Stake worms

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

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

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

Bracelets

The 20 mm parasite has a pink color, gives fewer manifestations, but the damage from it is colossal. Its oral cavity has teeth and plaques with which it scratches through blood vessels. The larvae penetrate the body through the skin of barefoot pedestrians.

The main task of the larvae is to enter the human mouth, from where, when they swallow saliva, they descend into the intestines, where the adult helminths are secreted. They feed on human blood, resulting in anemia. The threat is posed by their waste products, which poison the body. Signs of the presence of helminths are: persistent bronchitis, dermatitis, nausea, abdominal pain, digestive disorders. The heart suffers from this parasite - myocarditis may occur.

Trichinella

Female worms reach up to 4 mm, males are smaller. They die in the external environment and are applicable only within the body. The source of infection is the meat of immature animals. Through blood vessels, parasites spread to all organs, take root and can live quietly 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;
  • muscle pain;
  • conjunctivitis and swelling of the face.

Trematode parasites

Helminths, which are small in size, have a flat body, on which there are 2 suction cups. Most of them are hermaphrodites. Development requires an intermediate host.

Fluke

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

In the body of its final host, a human, current enters the duodenum, where the larva grows into an adult helminth. Aquatic bodies are infected with exhaustion by people who eat fish products and work in water containers (their waste penetrates the water).

Schistosomes

Helminths, having heterosexual individuals, needle-like in appearance. A pair of parasites produces up to 3000 eggs in 24 hours. A person becomes infected while bathing or with contaminated water. In the lungs and blood vessels, the larva becomes adult. After that, egg laying occurs in the intestine.

In the presence of schistosomes, the following is observed:

  • stomach ache;
  • appetite disturbance;
  • anemia;
  • change from diarrhea to constipation;
  • weight loss;
  • menstrual irregularities in women;
  • male impotence;
  • decreased school performance in children.

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

Where helminths can be placed

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". Most often they are located 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 have to be more careful with yourself and if the slightest doubts arise, 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 do not eat poorly cooked meat. Only then can the risk of infection be reduced.

It is great to live in this world and you do not want to think about parasites in the human body, but you have to do it. After all, every second person on Earth is infected with worms. The organism in which the parasite lives is a field of miracles, which will happen. But believing in fate is very weak.
