Wormen in ontlasting: Lintwormen, spoelwormen, ass maggots and trichinosis all intestinal parasites, used to play an important role as pathogens. The mandatory inspection of meat and vegetables and improved hygiene in general, they have become much rarer with us, although especially ass maggots yet to be determined regularly in children. Travelers from tropical countries spend ever more dangerous parasites along.

Lintwormen

Man is the main host for the tapeworm of beef, the pig and the fish (but intermediate host for the tapeworm of the dog). The beef tapeworm lays its eggs in the intestine of humans.

The intermediate host (het rund) takes them while grazing (the fertilized pasture) on. Arise larvae, that with the blood in the muscles, the liver and the lungs are placed and there is encapsulation. These so-called "fins" of intestinal parasites are reabsorbed by humans through eating beef. Once the bladder worms in the gut are, is the head of the tapeworm emerges, sucks itself to the lining of the small intestine and feeds on the intestinal contents.

This cycle is also true for the tapeworm of the pig and of the fish. The tapeworm is a 2 to 30 cm long chain of individual members, that once they are ripe, successively divested puts faeces disposed, where their presence can be established. People with tapeworm initially no complaints. Later join pressure sensation in the upper abdomen, famine or lack of appetite, nausea and vomiting.

The treatment of intestinal parasites is to make the head of the tapeworm with special means loose. Fins in the body can only be removed by surgery. When the tapeworm Dog the cycle in the intestine of the dog starts. Man is infected (eg. by stroking) and is thus intermediate host for the flippers; this condition is more dangerous, because the vesicles, especially in the liver and the lungs, but also in other organs such as brains, arrive and there are serious disorders cause. Even more dangerous is the, when people are infected with the eggs of the other tapeworms, they have developed in their own bodies, because they not only main host, but also between host are.

Trichonose

Trichinose, that in our country no longer appears, listed, because eating raw pork in some holiday countries still not safe, by the presence of the fins of trichinae. In the intestine of humans alter the larvae mature worms. The male intestinal parasites come after fertilization to, while females 1000 to 2000 larvae in the lymphatic vessels of the intestinal mucosa off. These larvae penetrate all organs, especially oxygen-rich muscle groups. Pain, nausea, vomiting and diarrhea announcing the serious illness. Distress and persistent high fever followed. The muscles are stiff and swollen as rheumatism.

Aarsmaden

There is no specific cure for trichinosis. Half of the patients can not be helped, and some death. Ass Maden live in the small intestine and in the upper parts of the large intestine. The approximately 1 cm long females lay their eggs outside the intestine, because they need oxygen for their development. This usually happens at night, because the sphincter of the anus is weaker than. The sleeper feels itching, scratching and bring the eggs back into the digestive system (children eg. by thumb sucking). Infection also occurs via vegetables, clothing, etc.. place. De witte, very motile maggots are usually massive in the stool found. Since contamination is particularly easy, is recommended as a family or even treat the whole class.

& Nbsp;

Spoelworm

The female roundworm lays daily 200 000 eieren in de thin intestine. These eggs are discharged with the stool and can then be reabsorbed by humans via fertilized vegetables or fruit, where they are in the same intestinal stages through as the ass maggots. Be the first adult roundworms two to three months later, about 20 cm long and as thick as a pencil are, in the stoelgang found. Because they multiply very quickly, a powerful treatment should be initiated. Roundworms can form clusters, the intestine or bile ducts clog; their metabolic residues can give rise to poisoning in the intestines.
