Development life cycle of pinworms

In order to become infected, it is necessary for the person to swallow the invasive eggs. Thus, they enter the digestive system, reach the intestines, where larvae hatch from the eggs. Thanks to special holes on the head, the larvae are easily attached to the intestinal walls. For development, the larvae feed on the contents of the intestines, blood.

When the larva develops to a mature individual (about 2 weeks), the stage of active reproduction begins. After mating, the males die and are taken out during bowel movements.

Pinworm life cycle

A month later, the female begins to lay eggs. To do this, at night, when the intestinal muscles are relaxed, she gets out and lays eggs around the anus, between the folds, in the perineum.

The female lays about 20,000 eggs, which develop within 6 hours. After that, she dies. The conditions around the anus are most favorable for the development of eggs - the temperature is kept around +36 degrees, the humidity is about 90%.

Ripe pinworm eggs become invasive, and larvae can already hatch from them. In the external environment, eggs retain their vital functions from a couple of hours to several months - it all depends on various factors.
