Parasites and worms in humans

Parasites live almost every person, according to statistics, 95% are carriers of "foreign" organisms. Studies confirm that a few "media" know about it. About what types of worms there are, how and when they lay eggs, consider in this article.

What is a parasite?

Helminths, or worms, is parasitic worms that reside in the body of animals, humans and even in plants. Pathogens of such diseases are helminths.


These include:

  • Tapeworms
  • Trematodes
  • Roundworms
  • Nematodes

Humanity knows more than 280 diseases caused by helminthic parasites. Some pathogens live and multiply in the stomach and human intestines, others – mainly in the lungs, liver, joints and muscles.

The most common helminthic disease of man are:

  1. Caused by pinworms – small parasitica, which reach a length of not more than 1 cm Representatives pinworms mainly active only at night, females are parasites crawling in the rectum, where the fall on the surface of the skin in the area below the groin, where, in fact, lay eggs in the folds of the skin, but dying. This is because the lifespan of parasites is not more than 2 months.
  2. The disease ascariasis is caused by the presence of pathogens – large worms – ascarids. The length of the parasites of more than 20 cm, and they live in the small intestine of man. Due to this, it is impossible to detect in the stool and time to start treatment.

Worms in a natural environment

To continue and develop their kind of parasites, when you leave the "source" of one host they are looking for another or for breeding are transferred to the external environment.

The transition of worms from one source of energy and nutrition to another (the carrier) is determined by the cycle of the parasites from person to person or from animal to human.

According to the characteristic of the transfer method, there are:

When the female parasites penetrate into the body of a human or animal, during the day they lay up to 250 thousand eggs. Eggs helminthic parasites are covered with specific shells, by which immune to external influence.

The growth and development of eggs within one week to two months, depending on the environment.Helminth larvae in the gastrointestinal tract is under the influence of juice, which will neutralize the shell, than loose larvae. The larva, Zn. already species of the parasite is absorbed into the blood vessels of the intestinal wall. The process of blood circulation contributes to the movement of the larvae, Zn. to carry helminth in the bloodstream. Thus, there is the spread of parasites in all organs. However, their activity occurs exclusively in the pulmonary alveoli, the larvae feeding on the blood, grow and multiply. Germinated individuals rise to the bronchi and develops the first symptom is a cough in which the larva gets in through the nasopharynx into the intestine, where grow.

Adult specimens of ascarids grows up to one year daily lay eggs, which come from fecal masses.

Disease caused by the development in the body of a helminth is called helminthiasis.

Before settling in the part of the body and lay eggs, "wandering" in the body of the larva looking for pure blood. Therefore, they are called "pure bloodsuckers", but as human blood or animal they no longer eat.In the danger zone first and foremost are the lungs and bronchial tubes, in consequence, the defeat of which causes such diseases:

the body
  • Tracheitis.
  • Pneumonia.
  • Pleurisy.
  • Laryngitis.
  • Aphonia.

Finish their development species of helminthic parasites in the upper gastrointestinal tract, where females lay their last larvae. If they come out of the human body along with the fecal masses, they continue their development in the ground. So, there is a cycle of parasites.

Development and reproduction of parasites

Worms ascarids almost all are hermaphroditic, only a small percentage of individuals of C. elegans or dioecious. In the process several stages of development, the parasite changes hosts or 3-4 sources of energy, food and indeed life. Among animals, worms choose ungulates or predators, so they can live tlaga eggs.

Parasites are "living" in man have with the host organism's immunological relationships, due to the fact that fully depend on his immune system and body.

Human infection with helminthic parasites

Human infection with helminthic parasites mostly is due to the lack of hygiene. If you do not wash their hands after excavation, to use dirty, raw or unpeeled fruits, berries and vegetables. In addition, an important role to play in infected insects, such as flies that are carriers of the eggs of worms.

The helminthic agents of diseases enter the human organs from Pets, or through a dirty pond while bathing.

In a healthy organism, when the parasites "this attempt," they must pass the triple barrier of the immune defense, which is missing in a weakened organism. In this case, the worms develop and grow into Mature individuals.

Symptoms development in the body helminthic parasites

Throughout the development in the body helminthic parasites, people gradually signátum waste products of the worms. So, a person will experience:

  • Sudden fatigue;
  • Weak appetite;
  • The constant changes of mood;
  • Headaches, migraine;
  • The imbalance of the digestive system;
  • Diarrhea;
  • Constipation;
  • Vomiting;
  • Anal itching;
  • Skin rash.

Bleeding caused by the parasites, such as hookworm, there are special glands at the tips of the teeth, which distinguish the enzyme of the anticoagulant.

Walking round in man, the heart, the lungs, the heart, the parasites can live up to 200 days.

If in the human body there is a large number of helminthic species, a day can drink more than 1 liter of blood. The waste product of worms is destructive toxic liquid secreted into the blood.

At the advanced stage of development of the parasites there is a pronounced anemia, which manifests itself in physical and mental weakness, signátum, a sharp deterioration of the appearance, tachycardia, and oedema of the feet is also evident heart failure.

In women, disturbed menstrual cycle and there was a failure in the biological rhythm of the body, and men suffer a loss of "male activity".

If in children and adolescents, parasites in the body, often found the following symptoms:

  • eating clay, sand;
  • lick metal objects;
  • used fly ash brick.

Infection through the skin occurs after lying on the grass, at work and in games with the earth. Places through which penetrate the larvae of the parasite, have all the signs of skin dermatitis and are called "soil itch" or "ground itch".

If human infection occurs through the area stop, the aisle seats will mainly be observed in the area of the interdigital folds. With the area of penetration can be covered with vesicles, itching, scabiem, and have red edges.

Symptoms of infestation that manifest on the skin, visible within 2 weeks.

Than be a parasite?

The symptoms and manifestations of diseases caused by the presence in humans of helminthic parasites appear and proceed on the basis of a particular type, the degree of destruction and the development of pathogens, as well as the individual reaction of each person.

The first symptom is a slight deterioration of the condition, poor sleep, possible insomnia. In this case, do not delay, and immediately contact the medical facility to undergo special tests and studies.

When running the form, the symptoms of helminthic pathogens found together or alternating: diarrhea, changes with vomiting and constipation.

The presence in the body of pinworms is characterized by burning and itching in the anus and also extends in the crotch region.

What is dangerous helminthic parasites to humans?

For helminthic disease is accompanied by constipation and incommoditas sensations in the abdomen, in which there is a swelling it is advisable to ask for help and advice from a specialist. This is because this symptom indicates the development of intestinal obstruction.

The complex degree of disease development, running form, accompanied by problems with the nervous system.

ascariasis and other such diseases that occur with the presence of paroxysmal cough.

Diagnosis of the presence of parasites in the body

In the case of infestation helminthic pathogens, or when the first symptoms of infection, be sure to get specialized checks and tests in a medical facility. Development in the body helminthic parasites, simply defined painless the analysis of a feces on eggs of worms.

To confirm the diagnosis, the analysis can be repeated two or more times.

Treatment of helminthiasis symptoms and their effects on the body

Based on the fact that helminths and helminthic parasites is a very broad concept, which includes many subspecies and varieties, for the treatment of each individual can be used in pills or decoctions, suppositories or even surgery. important in proper and effective treatment is correctly installed type parasitica organism.

Prevention of helminthic diseases

  1. It is not recommended to swim in dirty ponds with stagnant water.
  2. Meat and fish should be subject to mandatory heat treatment.
  3. Fruits and vegetables be washed thoroughly before use.
  4. Personal hygiene.

Worms are not uncommon to man, but adhering to the rules of personal hygiene, the risk of infection can be reduced to a minimum. If necessary, the treatment and dosage of drugs should be prescribed only by a doctor after examination and tests.
