To minimize the risk of infection should know the basic kinds of parasites living in man, and also about what kind of grades awarded being attacked by some views.

A person can act on the parasites as the main and the middleware host. In the second case, the worms use the body of the people in transport, the provision is up to the destination.

Parasites, for which the persons is the main host, are classified into the following types:

  • the easiest;
  • helminths.

The function of the disease protozoa

The simplest are the worms, however, their often ranked in their category. These parasites of man is called a protozoa, because they consist of one cell. Despite the simple structure, easy able to become the cause of serious diseases.

Most often inside a person inhabit these kinds of protozoa:

  • giardia;
  • amoebas;
  • Toxoplasma;
  • Trichomonas.

Parasites in the human body, the so-called lamblias, cause the development of giardiasis. This disease is characterized by the following symptoms:

  • dysbiosis of the colon;
  • vitamin deficiencies;
  • total weakening of the organism, coming as a result of intoxication products of life Giardia;
  • impaired digestion;
  • a deficiency of iron anemia.

Parasites in us, in the form of amoebas cause disease, which is called amoebiasis. This is manifested in the intestinal and neurotic disorders.

After infection with toxoplasms develops toxoplasmosis. These protozoa invade the following internal organs:

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

Special risk toxoplasmosis poses to pregnant women, because of Toxoplasma are able to penetrate through the placenta and get into the bloodstream of the fetus, which causes disturbances in its development, as well as intrauterine death.

Trichomonas infection leads to the development of trichomoniasis – a disease that affects the urogenital system of a person.

Features infestation with worms

Helminths – this is the most common parasites in the human body carriers, which is up to 80% of the population of the planet. Lead an active life, the settlement of various internal organs. Helminths are very often become a cause of developing chronic diseases, and if left untreated, leads to death of a person.

Despite the fact that the number of species of nematodes living inside the human body, more than four dozens of, it is appropriate to consider their most common species. These include:

  • pinworms;
  • ascaris;
  • Trichinella;
  • vlasoglavy.

Signs of infection of pinworms

Pinworms – this is the most common types of parasites in the human body. Disease caused by contamination of pinworms is called enterobiasis. This disease is called the disease of dirty hands, and it is to them most often, children suffer.

The length of the body of pinworms is not higher than 1, see the Place of their habitat is the intestine. When this female pinworms rather put off eggs in the folds of the anus, and crawling out.

The infection of pinworms is evidenced by the following symptoms:

  • itching in the rectal area;
  • symptoms of total intoxication;
  • anemia from lack of iron;
  • sleep disorders;
  • pain in the abdomen.

Symptoms of the ascarides

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

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

  • in a sick person's body temperature increases up to 40°C;
  • people are starting to feel the pain in the muscles;
  • a distinctive feature of trichinosis is eyelids.

Symptoms of whipworms

Whipworm – this is the whole worm, living only in the human body. Cause a disease called trichocephalosis. This worm parasite in the large intestine, damaging its mucosa and poisoning the body's waste products.

People infected with whipworms, have the following complaints:

What are the parasites living in the human body, in addition to the above mentioned? Another common type of worms are flukes or luck. This name is due to the fact that on the body of these worms have suckers, which are determined on the mucus membranes of the internal organs. These suckers allow the parasites to eat, absorbs the blood and nourishing substances.

Middleware master fluke is a fish. So assault them, most often occurs when the consumption of poorly treated fish.

The most common types of gill include the following types of worms:

  • opisthorchis felineus;
  • strongyloides stercoralis.

Siberian Fluke, whose body reaches a length of 2 cm, is also called cat a Coincidence, because this parasite lives in the body of the cat. The disease, caused by them, the so-called opisthorchiasis.

The main places of dislocation of the siberian Fluke are the channels of the gallbladder and pancreas, but also the liver. During the life of this parasite causes the development of gastritis, gastric ulcers and duodenal ulcers, as well as cholecystitis and pancreatitis.

When the infestation of strongyloides stercoralis in man, develops strongyloidiasis. The length of the worm does not exceed 2 mm. However, human life can be heavily damaged even so miserable parasite.

Rashes on the skin when worms

The main symptoms of strongyloidiasis are as follows:

  • in the emergence of chronic diseases of the digestive system;
  • on the occurrence of bronchial asthma;
  • on the occurrence of bronchitis.

A man infected with strongyloides stercoralis, becomes asthenic, suffering from frequent allergic rashes and anemia. In addition, this parasite is able to lead to the impossibility of conceiving a child.


It is a kind of tapeworm, the body, which reaches a length of several tens of meters. High masters of the cestodes are artiodactyls animals. In the human body, the worms they get when eating poorly processed meat animals.

Most often occur of the following types of tapeworms:

  • broad tapeworm;
  • the pig tapeworm;
  • bullish tapeworm;
  • The Echinococcus.

  • the person becomes asthenic.

The body of the pig tapeworm reaches a length of 8 meters. And infection of this worm is accompanied by other symptoms:

  • intestinal obstruction;
  • symptoms of total intoxication of the organism.

The length of the bull tapeworm reaches 18 meters. Assault them leads to the development of the disease, life-threatening. Symptoms of infestation are the following:

  • in the intestinal obstruction;
  • in disorders the function of the digestive system;
  • in iron deficiency anemia;
  • in an allergic reaction;
  • problems with the nervous system;
  • in general exhaustion of the body.

Echinococcus gets into the human body in the form of larvae, which form cysts. Special danger represent the large cysts, which are capable of thrashing around.

Diagnosis and treatment

See what they look like parasites, it is possible that the tracks photo. And if there is the slightest suspicion of their presence is the need to see a doctor immediately, who will determine the list of diagnostic activities and prescribe medications.

The main methods of diagnosis include the following:

  • laboratory studies of fecal masses;
  • blood tests;
  • a swab from the anus;

Therapy is carried out in several stages. In the initial stage is carried out the preparation of the body by the intake of sorbents, which contribute to the conclusion of toxins. Further, the patient is assigned antibacterial therapy. During this action, each antibiotic is focused on the destruction of only a certain kind of de-worming.

In the last step is carried out restorative therapy, which allows to strengthen the immune system and normalize the activity of all systems of the body.

Even knowing what will occur parasites, there is no need to try to destroy themselves. Self able to induce addictive to antibiotics, and aggravate the general condition of the patient.
