Parasites(from 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 entailed a simplification of their organization, the development of special fixation organs, improved development of the sexual organs and anoxybiotic respiration, which allows life in an oxygen-free environment.
The many parasites include:
- helminths;
- Mushrooms;
- viruses;
- protozoa;
- Worms;
- crustaceans;
- arachnids;
- Insects.
The hosts of parasites can be:
- Bacteria;
- protozoa;
- Plant;
- Animals;
- Human.
Parasites go through a complex development cycle: sometimes they require a change of 2-3 hosts, the organism of which 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:
- Omnipresent- found everywhere.
- Tropical- common in tropical climates.
According to biological and epidemiological characteristics, parasitoses are divided into:
- Geohelminthiasis- a disease in which parasites (helminths) develop first in the human body and then on an inanimate substrate, often in the soil.
- Biohelminthsis a disease in which the biological development cycle of a parasite (helminth) inevitably takes place in the body of living organisms other than humans.There are definitive hosts in whose bodies 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 definitive host, less often the intermediate host.
- Contact Helminthiasis- a disease in which parasites are released from the human body in a mature or almost mature state, making it possible to infect or re-infect another person (autoinfestation, 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 (e.g. roundworms, tapeworms).
- tissue parasites- live in the tissues of the human body (schistosomiasis, echinococcosis).
Depending on the place of residence of the owner (person):
- External parasites(Mosquitoes, horseflies, leeches, lice).
- Internal parasites(Helminthiasis):
- roundworms (nematodes – roundworms, filariae, whipworms, pinworms, Strongyloides, hookworms, trichinae);
- Flatworms:
- trematodes (flukes – cat flukes (opisthorchid), clonorchid, fasciola, schistosome);
- Cestodes (tapeworms – bovine and pork tapeworms, dwarf tapeworm, broadband worm, echinococci).
- Bacteriosis(leptospira, staphylococci, streptococci, shigella).
- Protozoa or protozoa(Amoebas, Lamblia, Trichomonas, common hosts of Chlamydia and the AIDS virus).
- Mycoses(Fungal diseases) - Candida, Cryptococci, Penicillium.
How parasites enter the human body
Infection with parasitosis can occur not only through dirty hands.Animal fur is a carrier of worm eggs (Ascaris and Toxocara), Giardia.
Pinworm eggs that fall from the wool remain viable for up to 6 months and enter the food tract through dust, toys, carpets, underwear, bedding and hands.
DogThrough moist breath, it distributes 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 tapeworm.
So, there are several ways parasites enter the human body:
- nutritionally(through contaminated food, water, dirty hands);
- Contact household(from household items, from infected family members, pets);
- transmission(about blood-sucking insects);
- percutaneous,or active (in which the larva enters the human body through the skin or mucous membranes upon 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 immunodeficiency arises, conditions are created for the penetration of pathogens from outside, as well as for the “disinhibition” of internal foci of infection);
- Many species of helminths, upon entering the digestive tract, secrete antienzymes that protect them from death;the digestive process is disrupted, toxic-allergic reactions of varying severity occur: urticaria, bronchial asthma, atopic dermatitis;
- developmental stages (egg, larva, host change);
- the ability of eggs to survive in the external environment for years;
- sexual reproduction, in which the exchange of genetic information occurs, 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 immunoprophylactic methods, as the immune response is weak and unstable;
- wide distribution of helminths, many habitats (water, soil, air, plants and animals).
Epidemiology of parasitoses
Due to increasing migration processes, the variety of helminths parasitizing the human body is increasing significantly.Currently, 70 of more than 260 existing parasite species are common.There is a tendency to increase infections 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 suffer from health problems due to the presence of parasites in the body.Improving the health of the body (proper nutrition, physical exercise, hardening procedures) without ridding the body of parasites does not have a pronounced positive effect.
They are everywhere...According to the World Health Organization (WHO), helminths and other types of parasites are found not only in the gastrointestinal tract, but also in vital organs: the brain, heart, lungs, liver and kidneys.
Cause of many diseases
During their lifetime, helminths secrete special substances - toxoids, which are strong poisons and allergens.It is parasitoses (protozoa, fungi and helminths) that cause 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, problem skin, headaches, appetite disorders, reduced immunity - these can be signs of current parasitosis.
If not treated...When parasites remain in the human body for a long time, the immune system suffers greatly.The constant battle with foreign antibodies leads to exhaustion and the development of a secondary immune deficiency.
Parasitosis leads to:
- to hypovitaminosis and lack of trace elements: potassium, copper, manganese, selenium, zinc, magnesium, silicon;
- to hematopoietic disorders;
- hormonal imbalance;
- vascular permeability is impaired;
- The body's defenses against cancer suffer.
How were you saved before?For thousands of years, humans received antimicrobial, antiparasitic and antiviral natural ingredients through a predominantly plant-based diet.Reducing the consumption of wild plants, fruits and berries, replacing them with cultivated vegetables and fruits, as well as thermal and industrial processing have 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 drug industry producing antibiotics has led to a decline in antiparasitic immunity.
Traditional medicine to eliminate parasites in the human body
Medical synthetic anthelmintics have their advantages and disadvantages.There are three main negative factors:
- often they only affect the gastrointestinal forms of parasites;
- very toxic to the human body;
- cause many side effects.
Science doesn't stand still!All over the world there is intensive scientific research into the antibiotic effects of plants.In terms of their effectiveness, they are in no way inferior to synthetic antibiotics, but do not cause the side effects characteristic of synthetic drugs.The healing components of plants are complex natural phytoncidal complexes that can rid the human body of many parasites at various stages of development.
Nature!This will help us!Preparations of plant origin are significantly 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.
Parasitoses are widespread diseases with toxic and damaging effects on the human body.Since treatment with chemical drugs has a negative effect on the body, herbal products are the optimal solution to the problem of combating parasitosis.
