What helminths can parasitize in the gastrointestinal?

Many helminths (worms) can parasitize in the human gastrointestinal tract. The most common are pinworms – white roundworms 8-12 mm long. They enter the human body if hygiene is not observed. Roundworms are also often found – these are large roundworms: the length of the male can reach 25 cm, and the female – 40 cm. Infection occurs when personal hygiene is not observed. Pork tapeworms (pork tapeworm, armed tapeworm) and bovine tapeworm (unarmed tapeworm) are also dangerous parasites for humans – these are flat tapeworms. Pork tapeworm reaches 2-3 m, and bovine – up to 10 m. Infection with these parasites occurs when eating raw or undercooked, undercooked meat.
