Clinical and laboratory diagnosis of enterobiosis

Abstract

Enterobiasis is a human parasitic disease, the causative agent of which is the human pinworm (Enterobius vermicularis), a milky-white spindle-shaped helminth, the length of the male is 3-5 mm, the female is 8-12 mm, the eggs are colorless, transparent, the size is 50-60 x 20-30 microns, the shape of the egg is oval-asymmetric, human infection occurs when swallowing mature pinworm eggs, which contain motile larvae. The pathogen parasitizes in the lower part of the small intestine and the upper part of the large intestine, which is its only host. Mostly children are affected, but there are cases among the adult population. The mechanism of transmission of the disease is fecal-oral, the contact-household route of transmission is significant. The main factor is hands contaminated with helminth eggs, as well as contaminated (dirty) household items (door handles, surfaces of furniture, windows and window sills, dishes, toys, children's pots), and less often - contaminated food products.
