The most common types of parasites of the human body

People are surrounded by a large number of parasitic microorganisms. Parasites are creatures living at the expense of its host.

And parasites causes infection

Internal parasites – a lower species of flora or fauna, whose life takes place inside the body of the carrier. They can also live outside. A parasitic organism feeds at the expense of his master.

Infection can occur through direct contact of a healthy person with sick people or animals. Infection also often occurs through the soil. People become infected when working with the soil in which earlier hit the parasites with fecal the patient.

Inside the human parasitic organisms move around the body and choose the most convenient place. They can live in various vital internal organs, destroying their structure. They can hide inside various other infections. Drugs for the treatment of the primary disease in this case, it will be ineffective.


Various bacteria and worms can parasitize in the human body. Infectious disease often takes place without obvious signs. The only way to discover them is to take the feces for analysis. The doctor will tell, who settled in the body, and provide a list of drugs to get rid of them. Not every drug may suit a particular patient.

Parasites in the body, man can exist over a long period of time, unaware of the presence of the disease. This is due to a complete lack of symptoms in some patients. When parasites can experience a variety of signs of infection. Their expression is associated with individual characteristics.

In the front part of the parasite is a special suction Cup, which Ancylostoma attached to the walls of the intestine. Eggs microorganism are sufficiently large in size and translucent shell. Only in some cases Ancylostoma infection can occur after contact with animals. These parasitic organisms can live up to 8 years. Every day they delay more than 20 thousand eggs.

The incubation period for hookworm up to several months. After that, the patient develops pronounced symptoms. A person may experience:

Each of them disturbs the functioning of certain internal organs. These parasites live in the body long enough. During this period of time a person develops a chronic intoxication of the organism.


Toxocara and a tapeworm

Toxocara – the microorganism, the main carrier of which is the dog. The length of this parasite can range up to 25 cm. the Adults are actively breeding. Their eggs come out along with faeces of the dog. Dogs are encouraged to walk away from playgrounds and land for planting and harvesting. In another case, the parasite can enter the human body. In human body the organism develops, but does not emit eggs out.

The most dangerous are Toxocara, which affects the organs of vision. In this case, patients often remove the eyeballs. The patient has the following symptoms:

  • fever;
  • cough;
