To combat helminth infection is easy enough, it is only important to know which of the hundreds of species we are fighting. For this, the first manifestations of infestation, it is necessary to consult a doctor and get tested. In medical practice there is a General division of parasitic worms into groups:

The type of localization

Enteric (live in the gastrointestinal tract, affecting the small intestine):

  • Round helminth.
  • Tapeworms.

  • Flat worms.

By way of infection

  • Dwarf tapeworm.
  • Pinworms.

helminth (infection occurs through contact with animals or eating infected meat, which have not passed thermal processing):

  • The bovine tapeworm.
  • Pork tapeworm.
helminth (infection occurs through unwashed vegetables, fruits, herbs):
  • Roundworm.
  • Trichina.

According to biological characteristics

This group of parasites include:
  • Tapeworms.
  • Roundworms.
  • The flukes.

The most common helminth

There are a number of types of helminth parasites that live in humans by sucking all the power and nutrients. As a rule, the person begins to notice signs of helminth only after he has already suffered irreparable damage.

Understanding which parasites are inhabitants of the human body the most, pay attention to the group of roundworms. Such helminth infection occurs more often than others. They get into the digestive tract, penetrate the intestine and begin to multiply at a staggering rate, parasites in humans.
