THE MOST COMMON TYPES OF WORMS




Pinworms - one of the most common types of worms. There may be from different socio-economic groups, especially common in children. They are not dangerous, but can cause considerable discomfort.

Typically, white, length about 6.4 mm, they live in the lower intestine, cecum and colon. They crawl out of the anus and lay eggs (up to 15 thousand per day). Several hours later, the eggs can already cause the infection to others, especially until they are light, are in the air, fall on clothes, walls, sheets and lie in wait. Although this parasite is easy to get rid of most of the children are often infected again when the comb itchy anus, and then put their fingers in his mouth, or do not wash their hands before eating.

Symptoms: itching in the anus, the gnashing of teeth during sleep, fatigue, diarrhea, bad breath, and dark circles under the eyes.

 

Roundworms - the second group intraenteric parasites. They live in the intestines, they can reach a length of 43 cm. Discover them harder than pinworms, because they are attached to the walls of the intestine. They secrete toxic products of its life in the bloodstream, "master." In the case of the most heavily infected, they penetrate into the lungs, liver, brain, eyes, and ears, causing serious damage.

Infection begins with ingestion of the organism "host" of eggs, which are usually in contaminated soil, or on fruits and vegetables grown on this soil. Children easily become infected when put their dirty hands in their mouths or do not comply with hygiene meal.

Symptoms: flatulence (bloating, flatulence) and pain in the intestinal tract, diarrhea, jaundice, peritonitis, undigested food, chronic dry cough, loss of energy. There are cases of violations of the balance of blood sugar levels, weight loss and fatigue.

 

Trichinella - parasitic roundworm to 4.5 mm long, lives in the intestine of a human or animal, causing trichinosis. Trichinosis - a serious disease with a high mortality rate (up to 30% of those infected). The main features of this helminthiasis similar to the symptoms of typhoid fever include headache, diarrhea, facial swelling, aches throughout the body, raising the temperature to 40 ° C.

Trichinella enter the human intestine capsules. In the intestine capsules are transformed into young Trichinella that as they grow older fertilize the females and die. Fertilized females are introduced into the intestinal wall and produce a host of tiny larvae live long 0,09-0,1 mm, with a current carried by the blood and lymph through the body of the host. From the capillaries larvae actively migrate to striated muscles increase in size and encapsulated in 2-3 weeks, maintaining the viability of up to a year or more. For further development of encapsulated Trichinella should get into the bowels of another mammal. Humans can be infected by eating pork. It can be up to 15 thousand per 1 kg of Trichinella into the pig meat. Goes on sale the meat is tested and if it found Trichinella, destroyed, since the heat treatment is not effective. Do not buy meat from questionable sellers must pay attention to the presence of stamps on carcasses and ham.

 

The tapeworms - belong to the third group intraenteric parasites. There is a whole family of these worms, which includes beef tapeworm, pork tapeworm, dog tapeworm, broad fish tapeworm, dwarf tapeworm and Echinococcus. They have their own system of digestion of food, since they absorb nutrients, especially vitamin B12 and folic acid via the skin. Toxic waste emitted by them, cause stress and harmful to the body, "master."

Usually infection occurs when consuming raw or undercooked pork, beef or fish. Dog tapeworm is common in children, because of the close contact with pets (cats and dogs). This parasite is not only eats our food, but often sucks our blood, causing anemia, abdominal discomfort and pain, diarrhea, toxemia, lack of appetite, nausea, weight loss, fatigue, lack of clarity of thought, hunger pains and allergic diseases.

Some tapeworms can cause an imbalance of sugar - as a result of people either lose weight or gain weight too.

 

Roundworm. Especially prevalent in children of preschool and younger. The life cycle of the roundworm is that adults - intestinal parasites - lay eggs (up to 200,000 from a single individual), which fall to the ground with the feces, where optimal conditions of moisture and oxygen in them developing larvae survive for several years. From the soil eggs can get your hands on, vegetables, berries, and which are entered in his mouth. In the intestine, the larvae hatch from the eggs penetrate through a wall into the venous or lymphatic channel and reach the lungs, break through the wall and out of the alveoli in the airways. The maturation of the lungs is carried out, then the young worms migrate through the bronchioles into the throat where they are swallowed and finally enters the small intestine. Adult worm reaches 25-30 cm in length, helminth life expectancy in humans - about one year.

 

In most patients, the disease is asymptomatic, but may show decreased appetite, nausea, abdominal pain, unstable stool, headache, insomnia, irritability. During migration of the larvae cause liver damage, especially the intestines and lungs (persistent cough, often at night, fever, eosinophilia and pulmonary infiltrates).

 

Whipworm, pathogen trichuriasis - is widespread in our country. Infection occurs by ingestion of infective eggs a person from contaminated water and food, as well as contamination of eggs through household items. Whipworm larva feeds on the blood and lymph capillary network of the intestinal wall. The lifespan of the parasite - about 5 years.

 

Clinical manifestations trichuriasis are well-known pediatricians, internists, gastroenterologists and oncologists complex of symptoms: intestinal colic, intestinal motility disorders, exhaustion, intoxication, weakness, a sharp decline in immunity, frequent colds, persistent goiter, anemia, diarrheal disorders, and others., However, this diagnosis is extremely rare. Whipworm infestation in children is one of the reasons FIC syndrome (often ill children), adults - chronic fatigue syndrome (in combination with certain types of viruses).

 

Trematodes - flatworms, invading the liver, lungs, intestines and blood. People usually become infected when they absorbed raw or undercooked fish or crabs. Eating contaminated vegetables, such as water chestnuts, watercress, drink or stay in contaminated water can also serve the conditions for dealing with these parasites.
