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 evolution of organisms from free-living forms.

Their adaptation to certain living conditions included the simplification of their organization, the development of special attachment organs, the increased development of the genitals, and anoxic respiration, which allows them to live in an oxygen-free environment.

Many parasites include:

• helminths;
• mushrooms;
• viruses;
• protozoa;
• snakes;
• crustaceans;
• arachnids;
• insects.

Hosts of parasites can be:

• bacteria;
• protozoa;
• plants;
• animals;
• Human.

Parasites go through a complex cycle of development: sometimes they have to change 2-3 hosts, where the organism is intermediate (the helminth passes through the larval stage) or definitive (the helminth becomes the adult, invasive).

Classification of parasites

According to their distribution, parasites are divided into:

• Everywhere- found everywhere.
• Tropics- common in tropical climates.

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

• Geohelminthiasis- a disease in which parasites (helminths) develop first in the human body and then on a non-living substrate, often in the ground.
• Biohelminthosesis a disease in which the biological development cycle of a parasite (helminth) must necessarily take place in the body of living beings other than humans.There are definitive hosts, in the bodies of which helminths develop during the sexual stage, as well as intermediate hosts, where 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 fully developed or almost fully developed, resulting in the possibility of infecting another person or re-infecting them (autoinfection, reinvasion).

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

• Luminal parasites- live in the intestinal cavity and other cavities of the human body (eg roundworms, tapeworms).
• Parasites in tissues- live in the tissues of the human body (schistomatosis, echinococcosis).

According to the residence of the owner (person):

• External parasites(mosquitoes, horseflies, lice).
• Internal parasites(helminthiasis):
  • roundworms (nematodes - roundworms, filaria, whipworms, pinworms, strongyloides, hookworms, trichinella);
  • flatworms:
    • trematodes (flakes - cat fluke (opisthorchid), clonorchid, fasciola, schistosome);
    • cestodes (tapeworms - bovine and porcine tapeworms, dwarf tapeworms, broad tapeworms, echinococcus).
• Bacterial infection(leptospira, staphylococcus, streptococcus, shigella).
• Protozoa or protozoa(amoeba, lamblia, trichomonas, often hosts chlamydia and AIDS virus).
• Mycoses(fungal diseases) - candida, cryptococcus, penicillium.

How parasites enter the human body

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

Eggs shed from wool remain viable for up to 6 months and enter the alimentary canal through dust, toys, blankets, underwear, bedding and hands.

A dogwith moist breath it spreads eggs up to 5 meters away (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 way 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(with contaminated food, water, dirty hands);
• contact-home(with household items, from infected family members, pets);
• shipment(with blood-sucking insects);
• through skin,or active (where the larva penetrates the skin or mucous membrane into the human body during contact with contaminated soil, when swimming in open water).

Adaptive features of parasites:

• long life expectancy (helminths live in the human body for many years, and sometimes as long as the owner of the parasite lives);
• the ability to suppress or change the immune response of the host organism (immune deficiency occurs, conditions are created for the entry of pathogenic substances from the outside, as well as for the "elimination" of internal foci of infection);
• Many types of helminths, when they enter the digestive tract, secrete anti-enzymes, which saves them from death;the digestive process is disturbed, toxic-allergic reactions of varying severity occur: urticaria, bronchial asthma, allergic dermatitis;
• developmental stage (egg, larva, host change);
• the ability of eggs to survive for many years in the external environment;
• sexual reproduction, where the exchange of genetic information takes place, and this is the highest level of development, which leads to the increase of a heterogeneous population, that is, the parasites become less vulnerable;
• lack of immune defense mechanisms, as 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 human migration, the diversity of helminths that infect the human body increases significantly.Currently, 70 species of parasites are common out of more than 260 extant.There is a tendency to increase 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 live a healthy lifestyle experience health problems due to the presence of parasites in their bodies.Improving the health of the body (proper nutrition, exercise, hardening methods) without ridding the body of parasites does not have a noticeable positive effect.

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

The cause of many diseases

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

• cholecystitis;
• cholelithiasis;
• pancreatitis;
• colitis;
• diabetes;
• bronchial asthma;
• allergic dermatitis.

Chronic fatigue, irritability and anxiety, hyperactivity in children, anemia, brittle nails and hair, skin problems, headaches, appetite, reduced immunity - these can be signs of existing parasites.

If not treated...When parasites are in the human body for a long time, the immune system suffers greatly.In the constant fight against foreign antibodies, it comes to fatigue, that is, to develop secondary immunodeficiency.

Parasitosis leads to:

• with vitamin deficiency and depletion of trace elements: potassium, copper, manganese, selenium, zinc, magnesium, silicon;
• to hematopoietic diseases;
• hormonal imbalance;
• vascular permeability is reduced;
• The body's anti-cancer defenses suffer.

How were you saved before?For thousands of years, people who ate a mostly plant-based diet were given antibiotics, anti-parasitic and anti-viral natural substances.Reducing the consumption of wild plants, fruits, berries, replacing them with cultivated vegetables and fruits, thermal and industrial processing has led to a reduction in the consumption of natural phytoncides and antibiotics.As a result, humans have become easy prey for many microbes.The rapid development of the pharmaceutical industry that produces antibiotics has led to a decline in parasite resistance.

Traditional medicines to eliminate parasites in the human body

Pharmaceutical anthelmintics have their advantages and disadvantages.There are three main negative factors:

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

Science does not stand still!A lot of scientific research is being done all over the world on the antibiotic properties of plants.In terms of effectiveness, they are not inferior to synthetic antibiotics, but do not cause the side effects characteristic of synthetic drugs.The healing elements of plants are complex natural phytocidal complexes that can rid the human body of many parasites at various stages of their development.

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

Parasites are widespread diseases that have toxic and harmful effects on the human body.Since treatment with chemicals has a negative effect on the body, the optimal solution to the problem of fighting parasites is natural medicine.
