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 prevent this. These are the lower plant and animal forms, living at the expense of the owner. Translated from Greek, they mean - freeloader.

In the path of parasitism, they can be external or internal.

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

The plaques 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, in the first place nematodes - they reach great length and have the shape of earthworms, hence the name - roundworms, these are:

  • roundworm;
  • pinworms;
  • hookworms;
  • Trichinella.

Roundworm

One of the most common nematodes is a parasite, in some cases up to 45 cm in size. The female lays 200, 000 eggs and this process occurs regardless of the presence of males in the host's body. Together with the feces, the eggs fall into the ground, where, when favorable factors arise, they transform 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 can occur serious consequences, rupture of postoperative sutures, the appearance of pancreatitis. Roundworms are especially dangerous for pregnant women - their penetration into the fetus is possible.

Oysters

Small worms, up to 10 mm in size, are infected mainly by children, more often in kindergartens. A sick person causes an 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 productivity;
  • sleep disorders;
  • nervous disorders.

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

Hookworm

The parasite 20 mm has a pink color, gives fewer manifestations, but the damage from it is colossal. His oral cavity 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 intestine, where adult helminths are released. They feed on human blood, which leads to anemia. The threat is their waste products, which poison the body. Signs 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 reach 4 mm, the males are smaller. They die in the external environment and are viable only in the body. The source of infection is raw meat from animals. Through the blood vessels, the parasites are distributed to all organs, take root and can live peacefully for 20 years.

Trichinella worm from the human body

The most common signs of infection are:

  • increase in the blood test for eosinophilic leukocytes;
  • raising the temperature to 40 ° C;
  • muscle pain;
  • conjunctivitis and swelling of the face.

Trematode parasites

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

Fluck

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

In the body of the last host, a human, the methyl is introduced into the duodenum, where the larva grows to an adult helminth. Water bodies are infected with methyl by people who eat fish products and work on water vessels (their waste products penetrate the water).

Schistosomes

Helminths having heterosexual individuals resembling the appearance of needles. One parasitic pair produces up to 3, 000 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. Then the laying of eggs takes place in the intestines.

In the presence of schistosomes, the following is observed:

  • stomach pain;
  • appetite disorder;
  • anemia;
  • change from diarrhea to constipation;
  • weight loss;
  • menstrual disorders in women;
  • impotence in men;
  • reduced school performance in children.

When introduced into the nerve fibers, the development of paralysis, 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". More often they are found 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 the parasites live in the body is not difficult at all. You just have to be more careful with yourself and if the slightest suspicion arises, 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 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. Eventually, 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 destiny is the lot of the weak.
