Classification of parasites and worms living in the human body

worm from the human body

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

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

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

Flat ones are divided, in turn, 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, where the name comes from - roundworms, these are:

  • roundworm;
  • pinworms;
  • hookworms;
  • trichinella.

Roundworm

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 regardless of the presence of a male in the host's body. Together with feces, the eggs fall into the ground, where, when favorable factors arise, they are transformed 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 ascaris, serious consequences may occur, rupture of postoperative sutures, the occurrence 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 infected with them mainly 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:

  • nighttime itching of the anal area;
  • decreased 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 harm from it is colossal. His mouth has teeth and plates with which he gnaws through 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, when 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, which poison the body. Signs of the presence of helminths are: persistent bronchitis, dermatitis, nausea, abdominal pain, digestive upset. The heart suffers from this parasite - myocarditis may appear.

Trichinella

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

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 facial swelling.

Trematode parasites

Helminths are small in size, flat body, on which there are 2 suction cups. Most of them are hermaphrodites. An intermediate host is needed for development.

Fluke

Helminth - hermaphrodite, grows up 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 fish scales. If at this moment a person eats poorly 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 grows to an adult helminth. Water bodies are infected with fluke by people who eat fish products and work on water vessels (their waste products penetrate into the water).

Schistosomes

Helminths, having heterosexual individuals, resembling needles in their appearance. One parasite pair 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 an adult. After this, eggs are laid in the intestines.

In the presence of schistosomes, the following is observed:

  • stomach ache;
  • 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?

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

The human body, where the parasite lives, becomes weakened and begins to suffer from various diseases, so how to determine that parasites live in the body is not difficult at all. You just need to be more attentive to yourself and if the slightest suspicions appear, you cannot 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, do not drink raw water and do 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. After all, every second person on Earth becomes infected with worms. The organism in which the parasite lives is a field of miracles, which will happen. But trusting in fate is the lot of the weak.
