Parasites in the human body

Parasites(from the Greek parasitos - parasite, parasite) - lower plant and animal organisms that live outside or inside another organism (host) and feed at its expense.

Parasitesarose in the process of historical development of organisms from free-living forms.

Their adaptation to certain living conditions involved a simplification of their organization, the development of special fixation organs, increased development of the genitals and anoxybiotic respiration, which makes it possible to exist in an oxygen-free environment.

Many parasites include:

• helminths;
• mushrooms;
• viruses;
• protozoa;
• worms;
• crustaceans;
• spiders;
• insects.

The hosts of parasites can be:

• bacteria;
• protozoa;
• plants;
• animal;
• Human.

Parasites go through a complex cycle of development: sometimes they require a change of 2-3 hosts, whose organism is intermediate (the helminth goes through larval stages) or final (the helminth becomes sexually mature, invasive).

Classification of parasites

According to their distribution, parasites are divided into:

• Ubiquitous- found everywhere.
• Tropical- common in tropical climate zones.

According to biological and epidemiological characteristics, parasites are divided into:

• Geohelminthiasis- a disease in which parasites (helminths) first develop in the human body and then on a non-living substrate, often in the soil.
• Biohelminthosisis a disease in which the biological development cycle of a parasite (helminth) necessarily takes place in the body of living beings other than humans.There are final hosts in whose body the helminths develop to the sexually mature stage, as well as intermediate hosts in which the parasite is in the larval stage or reproduces asexually.Humans are often the final host, less often the intermediate host.
• Contact helminthiases- a disease in which parasites are released from the human body mature or almost mature, as a result of which it is possible to infect another person or re-infect him (autoinfestation, reinvasion).

Depending on the location of the parasite in the human body:

• Luminal parasites- lives in the intestinal cavity and other cavities in the human body (e.g. roundworms, tapeworms).
• Tissue parasites- lives in the tissues of the human body (schistomatosis, echinococcosis).

According to the place of residence of the owner (person):

• External parasites(mosquitoes, horseflies, leeches, lice).
• Internal parasites(helminthiasis):
  • roundworms (nematodes - roundworms, filaria, whipworms, pinworms, strongyloides, hookworms, trichinae);
  • flatworms:
    • trematodes (flukes - cat fluke (opisthorchid), clonorchid, fasciola, schistosome);
    • cestodes (tapeworms - cattle and pig tapeworms, dwarf tapeworms, broad tapeworms, echinococcus).
• Bacteriosis(leptospira, staphylococci, streptococci, shigella).
• Protozoa or protozoa(amoebae, lamblia, trichomonas, often hosts of chlamydia and AIDS virus).
• Mycoses(fungal diseases) - candida, cryptococcus, penicillium.

How parasites enter the human body

You can become infected with parasitosis not only through dirty hands.Animal fur is a carrier of worm eggs (ascaris and toxocara), Giardia.

Pinworm eggs that fall from wool remain viable for up to 6 months and enter the alimentary canal through dust, toys, carpets, underwear, bedding and hands.

Dogthrough moist breath, it spreads eggs over a distance of up to 5 meters (a cat - up to 3 meters).

Fleasdogs also carry worm eggs.Ascaris eggs enter the human body through poorly washed vegetables, fruits, berries, herbs, dirty hands and are also spread by flies.

And improperly prepared kebab or homemade lard is a route of infection with trichinosis;poorly salted fish, caviar or "stroganina" - opisthorchiasis and tapeworms.

So there are several ways that parasites enter the human body:

• nutritionally(through contaminated food, water, dirty hands);
• contact household(through household items, from infected family members, pets);
• transmission(via blood-sucking insects);
• percutaneous,or active (where the larva penetrates the skin or mucous membranes of the human body during contact with contaminated soil when swimming in open water).

Adaptive properties of parasites:

• long life expectancy (helminths live in the human body for years, and sometimes as long as the owner of the parasite lives);
• the ability to suppress or modify the immune response of the host organism (a state of immune deficiency occurs, conditions are created for the penetration of pathogenic agents from the outside, as well as for "disinhibition" of internal foci of infection);
• Many types of helminths, when they enter the digestive tract, secrete anti-enzymes that save them from death;the digestive process is disturbed, toxic-allergic reactions of varying severity occur: urticaria, bronchial asthma, atopic dermatitis;
• developmental stages (egg, larva, change of hosts);
• the ability of eggs to survive for years in the external environment;
• sexual reproduction, where there is an exchange of genetic information, and this is the highest stage of development, which leads to an increase in the heterogeneous population, that is, the parasites become less vulnerable;
• lack of immunoprophylaxis methods, since the immune response is weak and unstable;
• wide distribution of helminths, many habitats (water, soil, air, plants and animals).

Epidemiology of parasites

Due to increasing migration processes, the diversity of helminths that parasitize the human body is significantly increasing.Currently, 70 species of parasites are common out of more than 260 extant.There is a tendency towards increased infection with enterobiasis, giardiasis, toxocariasis, opisthorchiasis, diphyllobothriasis, tenidosis and echinococcosis.In the countries of Southeast Asia, Africa and Latin America, schistosomiasis and filariasis are common.

"Healthy" people...Many people who lead a healthy lifestyle experience health problems due to the presence of parasites in the body.Improving the health of the body (proper nutrition, physical training, hardening procedures) without ridding the body of parasites does not give a pronounced positive effect.

They are everywhere...According to the World Health Organization (WHO), helminths and other types of parasites are located not only in the gastrointestinal tract, but also in vital organs: the brain, heart, lungs, liver, kidneys.

Cause of many diseases

During their life, helminths secrete special substances - toxoids, which are strong poisons and allergens.It is parasites (protozoa, fungi and helminths) that are the trigger for many chronic diseases:

• cholecystitis;
• cholelithiasis;
• pancreatitis;
• colitis;
• diabetes mellitus;
• bronchial asthma;
• atopic dermatitis.

Chronic fatigue, irritability and anxiety, hyperactivity in children, anaemia, brittle nails and hair, problem skin, headaches, appetite disturbances, reduced immunity - these can be signals of current parasitosis.

If not treated...When parasites remain in the human body for a long time, the immune system suffers greatly.In the process of constant struggle with foreign antibodies, exhaustion occurs, that is, the development of secondary immunodeficiency.

Parasitosis leads to:

• for hypovitaminosis and depletion of trace elements: potassium, copper, manganese, selenium, zinc, magnesium, silicon;
• for hematopoietic disorders;
• hormonal imbalance;
• vascular permeability is weakened;
• The body's anti-cancer defenses suffer.

How were you saved before?For thousands of years, people who ate mainly plant foods received antimicrobial, antiparasitic and antiviral natural active substances along with them.Reducing the consumption of wild plants, fruits, berries, replacing them with cultivated vegetables and fruits, thermal and industrial processing has led to a decrease in the consumption of natural phytoncides and antibiotics.As a result, humans have become easy prey for many microorganisms.The intensive development of the pharmaceutical industry producing antibiotics has led to a decline in antiparasitic immunity.

Traditional medicine to eliminate parasites in the human body

Medicinal synthetic anthelmintics have their advantages and disadvantages.There are three primary negative factors:

• often they affect only the gastrointestinal forms of parasites;
• very toxic to the human body;
• cause many side effects.

Science does not stand still!Intensive scientific research into the antibiotic properties of plants is being carried out all over the world.In terms of effectiveness, they are not inferior to synthetic antibiotics, but do not cause the side effects characteristic of synthesized drugs.The healing components of plants are complex natural phytoncidal complexes that can rid the human body of many parasites at different stages of their development.

Nature!This is what will help us!Preparations of vegetable origin are much less toxic;if necessary, they can be prescribed in long courses;they activate antiparasitic immunity and effectively suppress the vital activity and reproduction of parasites in the human body.

Parasites are widespread diseases with toxic and harmful effects on the human body.Since treatment with chemical drugs has a negative effect on the body, the optimal solution to the problem of combating parasitosis is herbal products.
