Parasites in the human body: types and what are the

According to statistics, the infection of the worms more than half the world's population. Every person can become a so-called master-more than 300 species of these animals. Some of them may occur in a person who does not cause much concern. And others are often the cause of death.

type of parasite

To protect the body, you need to understand what can parasites live inside us, how to recognize their presence, and what treatment methods with modern medicine to their destruction.

Classification of parasites

The most common habitat is the intestines of worms. However, they can parasitize in various organs and tissues such as the liver, lungs, brain, under the skin and even the eyes.

Every person is exposed daily to contaminated. They are literally surrounded by people. Potential hazards are animals, even beloved Pets. The larvae of the worms can live in soil, water, food and even floating in the air.

To minimise the risk of infection, you should know the main types of parasites living in man, and what signs give infection of some sort.

People can act as parasites, such as basic and intermediate hosts. In the latter case, the worms use the human body transport, to deliver them to their destination.

Parasites, where the man is the primary host, is classified into the following types:

  • simple;
  • worms.

Features-infection, protozoa

Protozoa are not worms, but they often refer to their discharge. These parasites called protozoa, since they are composed of a single cell. In spite of the simple structure, the simplest can become the reason of development of serious diseases.

Number of people living in the following types of protozoa:

  • Giardia;
  • amoeba;
  • Toxoplasma;
  • Trichomonas.

Parasites in the human body, called Giardia causes giardiasis. This disease is characterized by the following symptoms:

  • dysbacteriosis of the intestine;
  • vitamin deficiencies;
  • The general weakening of the body occurs as a result of poisoning waste Giardia;
  • dysfunction of digestion;
  • iron-deficiency anemia.

Parasites of us in the form of amoebas cause a disease called amoebiasis. It occurs in the intestinal and neurotic disorders.

After infection, Toxoplasma develop toxoplasmosis. These simple amaze the following internal organs:

  • the brain;
  • eye;
  • of the heart;
  • of the nervous system.

In particular, the danger is toxoplasmosis in pregnant women, as toxoplasmosis is able to penetrate the placenta and enter the fetal blood, causing a disruption of his development, and fetal death.

Infection of particular parasites leads to the development of hepatitis C – a disease that affects the urogenital system.

Helminths are the most common parasites in the human body, as carriers, that is up to 80% of the world's population. They lead an active life, inhabited by a variety of internal organs. Worms are very often the cause of chronic disease, and if untreated, leads to death.

The most common helminths are worms:

  • nematodes;
  • flukes;
  • cestodes.



Infection of this species of worms exposed to both children and adults. In addition, the child of the nematodes are much more common. This fact is due to the fact that you can get them through everyday life. Just one touch on the subject, which is the eggs of these worms. But most often, infection occurs through dirty hands, unwashed fruits and vegetables.

Nematodes – round worms is due to the structure of their body, which vary in length from a few millimeters to several tens of centimeters.

Despite the fact that several species of nematode that live inside the human body, more than four decades, it is advisable to examine their most common varieties. These are:

  • pinworms;
  • roundworm;
  • Trichinella;
  • vlasoglavy.

Signs of infection

Pinworms are the most common parasites in the human body. This disease is called the disease of dirty hands, and it most often affects children.

Body length pinworms do not exceed 1 cm Place of their habitat is the intestine. When pinworm female prefer to lay eggs in the folds of the anus, and crawling out.

Infection of pinworms is evidenced by the following characteristics:

  • itching in the anus;
  • the symptoms of poisoning;
  • iron-deficiency anemia;
  • sleep disorders;
  • pain in the abdomen.

Signs of nematode infection

Roundworm provoke the development of ascariasis. These parasites inside of us to live in the small intestine. Symptoms of ascariasis vary depending on the development stage of the worms. When the larvae migrate through the bloodstream throughout the body, appear the following symptoms:

  • a slight increase in body temperature;
  • enlarged lymph nodes;
  • dry cough;
  • rales in the lungs.

When the parasites Lodge in the intestines, the symptoms change. They are expressed as follows:

  • dysfunction of digestion;
  • pains in the abdomen;
  • nausea, accompanied by vomiting.

The parasite also affects the nervous system. Infected people experience headaches, they have interfered with sleep quality, often hysterical spasms and mental fatigue.

Signs of infection of Trichinella

Trichinella causes a disease called trichinosis, which is killed. They can be infected by eating the flesh of animals, both domestic and wild, which was poorly cooked.

Identify trichinosis is possible with the following features:

  • the infected person loses his appetite;
  • he develops indigestion and abdominal pain;
  • the allocation of metabolic products of the parasite cause the symptoms of poisoning, expressed in the form of an allergic rash on the skin;
  • a human patient, the body temperature rises to 40°C;
  • people are starting to experience pain in the muscles;
  • feature of trichinosis is swelling of the eyelids.
treatment of parasites

Signs of whipworm infection

Whip worm is a nematode that lives only in the human body. This worm is parasitic in the large intestine, damaging its mucous membranes and poisoning the human body waste.

People infected by them, are the following allegations:

  • abdominal pain;
  • headache;
  • dizziness;
  • iron-deficiency anemia.


Some parasites live in the human body in addition to the above? The second common type of worms are the trematodes or flukes. This name is due to the fact that the body of these worms have suckers, which they attach to the mucous membranes and internal organs. These suckers allow the parasite to feed by sucking blood and nutrients.

The intermediate host of trematodes is a fish. Therefore, the infection, they often happen by eating poorly processed fish.

The most common flukes are the following types of worms:

  • Siberian flukes;
  • intestinal acne.

Siberian Fluke, whose body reaches a length of 2 cm, which is also called the cat Lucky, because this parasite live in the body of the cat. The disease caused by them is called opisthorchiasis.

The main places of dislocation of the Siberian Fluke are the channels of the gallbladder and the pancreas and liver. In the process of life, this parasite causes the development of gastritis, gastric ulcer and duodenal ulcer, cholecystitis and pancreatitis.

Once infected with intestinal acne in humans the disease develops. The length of the worm did not exceed 2 mm. However, human life can ruin even the little parasites.

The main symptoms of the disease are the following:

  • the emergence of chronic diseases of the gastrointestinal tract;
  • the appearance of bronchial asthma;
  • the emergence of bronchitis.

People infected with intestinal acne becomes infected, often suffer from allergic dermatitis and anemia. In addition, this parasite can lead to the impossibility of conceiving a child.


This form of tapeworms, the body reaches a length of several tens of meters. Intermediate hosts of cestodes are even-toed ungulates. The human body worms get by eating poorly processed meat.

The most common tapeworms:

  • tapeworm;
  • pork tapeworm;
  • beef tapeworm;
  • it's Echinococcus.

The tapeworm can reach a length of several meters, and can only live in the small intestine. Symptoms are expressed as follows:

  • happen paralysis;
  • anemia;
  • interfering with the function of the gastrointestinal tract;
  • man becomes thin.

The body of the pork tapeworm can reach a length of 8 meters. And infection of this worm is to be accompanied by the following symptoms:

  • intestinal obstruction;
  • signs of General intoxication.

Length beef tapeworm reaches 18 meters. Infection they lead to the development of conditions that threaten life. The symptoms are the following:

  • intestinal obstruction;
  • disorders of the gastrointestinal tract;
  • iron-deficiency anemia;
  • allergic reactions;
  • problems with the nervous system;
  • General exhaustion of the organism.

Echinococcus enters the human body, because the larvae, which form cysts. Special danger is caused by large cysts that can rupture.

Diagnosis and treatment

Look at parasites, look at the photos. And if you have the slightest suspicion of their presence should immediately contact your doctor, who will determine the list of diagnostic procedures, and prescribe treatment.

The main diagnosis included the following:

  • laboratory studies of fecal masses;
  • blood tests;
  • suppositories the anus;
  • CT and ultrasound.

Treatment of worms has been implemented in several stages. The initial stage of training the body through the ingestion of sorbents, promote detoxification. Next, the patient is assigned antibacterial treatment. Thus, the action of each antibiotic, which seeks the destruction of only a certain type of worms.

The last stage is regenerative therapy, which can strengthen the immune system and normalize the functioning of all body systems.


Even knowing that there are parasites, don't try to destroy them yourself. Self-medication can lead to dependence on antibiotics and worsen the General condition of the patient.
