One of the varieties of helminths affecting the human small intestine is the flat worm metagonimus, which is part of the class of parasites-flukes (trematodes).
The worm got its name not by chance. The fact is that his body has a special structure. So, its first part resembles a thin thread or hair, but to the posterior end sharply thickens.
Pubic lice are small insects that parasitize the human body. Lice choose mainly the pubic area (both in men and women), but can also live in other places where there are hair - underarms, abdomen, breasts.
The largest helminth that can parasitize in humans and animals is the wide ribbon (Diphyllobothrium latum or Dibothriocephalus latus): its adult individual can grow up to 12 meters in length.
