PINWARM (ENTEROBIASIS)

Enterobiasis -  widespread helminthiasis caused by pinworms - small round worms (nematodes) in white. Length of male pinworms 2-3 mm, the female pinworms - 9-12 mm. Caudal end of male spirally curved toward the ventral surface, while the female shipovidno pointed.

Sources of infection enterobiasis (pinworms): The infection of human pinworms plays a major role violation of the rules of hygiene. So often enterobiasis ill young children who attend preschool.

Modes of transmission enterobiasis (pinworms): Oral, contact, home. A person infected with pinworms, during sleep feels very itchy and scratches the skin, and the eggs of pinworms get into his arms and under his fingernails, contaminate underwear. Then the eggs of pinworms get out of bed and hands on household items and food products.

Forms of existence enterobiosis (pinworms): The life cycle begins with the fertilization of pinworms in the intestine of the female host where it is developing. Females pinworms, filled with eggs in number 5000-15000 pieces each, are not able to keep the mucous membrane of the intestines, they go down to the rectum and crawl from the anus to lay eggs in the perianal folds in the skin of buttocks and thighs, attaching them. After the deposition of eggs, the female dies, the duration of its life does not exceed 1 month. For the further development of eggs requires a special microclimate with a temperature of 34-36 C and high humidity (70-90%).
Suitable conditions for this - people in the crotch and perianalnyh folds. There are already mature eggs after 4-6 hours. Coming under the nails host eggs of pinworms get as optimal conditions for further development. After the penetration of eggs in zheluzhochno tract of them into larvae and an average of 2 weeks develop into adults who infest the lower parts of small and upper large intestine.
Life expectancy of up to 100 days, pinworms, and a state invazirovannosti (infection), particularly in children, due to repeated infections may last much longer.
Symptoms enterobiosis (pinworm) is a striking sismptomom enterobiosis perianal itching during sleep, often at night, from 23.00 to 1.00ch. It was at this time, worms may remain undetected, lay eggs that have matured in the morning to an infectious infective stage. When enterobioze observed intestinal disorders - frequent stools, sometimes having rimes slime colicky pain appear in the umbilical region and along the colon.
The consequences of parasitism in the body enterobiosis (pinworms) attaching to the intestinal wall, pinworms eat its contents, and are able to swallow the blood. Poisoning by an infected person's body waste products pinworm causes allergy. Toxins released pinworms, upsetting the nervous system, causing irritation, headaches, dizziness, insomnia, increased mental and physical fatigue. With the penetration of pinworms in the appendix may cause appenditsta. When enterobioze violated the suction process and digest food decreases the acidity of gastric juice.

Most of the children changed microbiocenose intestine. Malabsorption of nutrients and digestion in the intestine leads to weight loss, delayed development of the child. Mechanical effects of pinworms in the intestine leads to petechial hemorrhages, erosions. Pinworm parasitism leads to suppression of nonspecific immunity, which leads to increased incidence of viral, bacterial infections. When enterobioze children significantly reduced the level of copper, zinc and magnesium in the blood.
