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.

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

Their adaptation to certain living conditions meant the simplification of their organization, the development of special organs for fixation, enhanced development of genital organs and anoxybiotic respiration, which enables existence in an environment without oxygen.

Many parasites include:

• helminths;
• mushrooms;
• viruses;
• protozoa;
• worms;
• crabs;
• arachnids;
• insects.

Hosts of parasites can be:

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

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

Classification of parasites

According to their distribution, parasites are divided into:

• Ubiquitous- it's everywhere.
• Tropical- common in tropical climate zones.

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

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

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

• Luminal parasites- that live in the intestinal cavity and other cavities of the human body (for example, roundworms, tapeworms).
• Tissue parasites- that live 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, trichinella);
  • flatworms:
    • trematodes (flukes - cat fluke (opisthorchid), clonorchid, fasciola, schistosis);
    • cestodes (tapeworms - beef and pork tapeworm, dwarf tapeworm, broad tapeworm, echinococcus).
• Bacteriosis(leptospira, staphylococcus, streptococcus, shigella).
• Protozoa or protozoa(amoeba, lamblia, trichomonas, often hosts of chlamydia and the AIDS virus).
• Mycosis(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 the eggs of worms (ascaris and toxocara), Giardia.

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

A dogscatters eggs with moist breath at a distance of up to 5 meters (cat - up to 3 meters).

Fleasdogs also carry worm eggs.Ascarid 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 to get infected with trichinosis;slightly salted fish, caviar or "stroganina" - opisthorchosis and tapeworm.

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

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

Adaptive properties of parasites:

• long lifespan (helminths live in the human body for years, and sometimes as long as the host of the parasite lives);
• the ability to suppress or modify the immune response of the host organism (a state of immunodeficiency is created, 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, which saves them from death;the digestive process is disturbed, toxic-allergic reactions of varying severity appear: urticaria, bronchial asthma, atopic dermatitis;
• developmental stages (egg, larva, host change);
• the ability of eggs to survive for years in the external environment;
• sexual reproduction, during which there is an exchange of genetic information, which is the highest level of development, which leads to an increase in the heterogeneous population, i.e. parasites become less vulnerable;
• lack of immunoprophylaxis methods, because the immune response is weak and unstable;
• wide distribution of helminths, many habitats (water, soil, air, plants and animals).

Epidemiology of parasitosis

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

"Healthy" people...Many people who lead a healthy lifestyle have health problems due to the presence of parasites in the body.Improving the health of the organism (proper nutrition, physical exercises, hardening procedures) without ridding the organism 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 localized not only in the gastrointestinal tract, but also in vital organs: brain, heart, lungs, liver, kidneys.

The cause of many diseases

During their life, helminths secrete special substances - toxoids, which are strong poisons and allergens.Parasitosis (protozoa, fungi and helminths) are the trigger of many chronic diseases:

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

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

If left untreated...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:

• to hypovitaminosis and depletion of trace elements: potassium, copper, manganese, selenium, zinc, magnesium, silicon;
• to disorders of hematopoiesis;
• hormonal imbalance;
• vascular permeability is impaired;
• The body's defense against cancer suffers.

How have you been saved before?For thousands of years, people, eating mostly plant foods, received antimicrobial, antiparasitic and antiviral natural active substances along with them.Reduction in the consumption of wild herbs, fruits, berries, replacement with cultivated vegetables and fruits, thermal and industrial processing led to a reduction 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 that produces antibiotics has led to a decrease in antiparasitic immunity.

Traditional medicine for the removal of parasites in the human body

Medical synthetic anthelmintic drugs have their advantages and disadvantages.There are three main negative factors:

• they often affect only the gastrointestinal forms of the parasite;
• very toxic to the human body;
• cause many unwanted reactions.

Science does not stand still!All over the world, intensive scientific research is being conducted on the antibiotic properties of plants.In terms of effectiveness, they are not inferior to synthetic antibiotics, but they do not cause side effects that are characteristic of synthesized drugs.Medicinal components of plants are complex natural phytoncide complexes that can rid the human body of many parasites in different stages of their development.

Nature!That's what will help us!Herbal preparations are much less toxic;if necessary, long courses can be prescribed;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 parasite control is herbal products.
