vermin(from the Greek parasitos - parasite, parasite) - low plant and animal organisms that live outside or inside another organism (host) and feed at its expense.
verminarose in the process of historical development of organisms from free living forms.
Their adaptation to certain living conditions led to a simplification of their organization, the development of special fixation organs, the enhanced development of genital organs and anoxybiotic respiration, which makes it possible to exist in an environment without oxygen.
Many parasites include:
- helminths;
- mushrooms;
- viruses;
- protozoa;
- worms;
- crustaceans;
- arachnids;
- insects.
Hosts of parasites can be:
- bacteria;
- protozoa;
- plants;
- animals;
- Human.
Parasites go through a complex development cycle: sometimes they require a change of 2-3 hosts, whose organism is intermediate (the helminth passes 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) develop first in the human body, and then in a non-living substrate, often in the soil.
- Biohelminthosisis a disease in which the cycle of biological development of a parasite (helminth) necessarily occurs in the body of organisms other than humans.There are definitive hosts, in whose body the helminths develop to the stage of sexual maturity, 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 released from the human body mature or almost mature, as a result of which it is possible to infect another person or to be re-infected (autoinfection, reinvasion).
Depending on the location of the parasite in the human body:
- Luminal parasites- living in the intestinal cavity and other cavities of the human body (for example, roundworms, tapeworms).
- Tissue parasites- living in the tissues of the human body (schistomatosis, echinococcosis).
According to the residence of the owner (person):
- External parasites(mosquitoes, horseflies, leeches, lice).
- Internal parasites(helminthiasis):
- roundworms (nematodes - roundworms, filaria, whipworms, needleworms, strongyloides, needleworms, trichinella);
- flatworms:
- trematodes (flukes - cat fluke (opisthorchid), clonorchid, fasciola, schistosome);
- cestodes (tapeworms - bovine and porcine tapeworms, dwarf tapeworms, broad tapeworms, echinococcus).
- Bacteriosis(leptospira, staphylococcus, streptococcus, shigella).
- Protozoa or protozoa(amoeba, lamblia, trichomonas, often hosts of chlamydia and the AIDS virus).
- mycoses(fungal diseases) - candida, cryptococcus, penicillium.
How parasites enter the human body
You can get infected with parasitosis not only through dirty hands.Animal fur is a carrier of worm eggs (ascaris and toxocara), Giardia.
Worm eggs that fall from wool remain viable for up to 6 months and enter the alimentary tract through dust, toys, carpets, underwear, bedding and hands.
dogthrough moist breathing, spreads eggs at 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 vegetables, fruits, berries, herbs, dirty, poorly washed hands and are also spread by flies.
And improperly prepared kebab or homemade lard is a way of infection with trichinosis;lightly salted fish, caviar or "stroganina" - opisthorchiasis and tape.
So, there are several ways that parasites enter the human body:
- nursing(through contaminated food, water, dirty hands);
- contact families(through household items, from infected family members, pets);
- BROADCASTING(through blood-sucking insects);
- percutaneous,or active (in which the larva penetrates the skin or mucous membrane of the human body during contact with contaminated soil, when swimming in open water).
Adaptive properties of parasites:
- long life (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 arises, conditions are created for the penetration of pathogenic agents from the outside, as well as for the "disinhibition" of internal foci of infection);
- Many types of helminths, when they enter the digestive tract, secrete anti-enzymes, which save them from death;the digestion process is interrupted, toxic-allergic reactions of varying severity appear: 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, during which the exchange of genetic information takes place, and this is the highest stage of development, leading to an increase in the heterogeneous population, that is, parasites become less vulnerable;
- lack of immunoprophylaxis methods, as the immune response is weak and unstable;
- wide distribution of helminths, many habitats (water, soil, air, plants and animals).
Epidemiology of parasitosis
Due to the increasing processes of migration, the diversity of helminths parasitizing the human body is increasing significantly.Currently, 70 species of parasites are common out of more than 260 existing ones.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 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 exercises, strengthening procedures) without cleansing the body of parasites does not give a significant 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.
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 cause of many chronic diseases:
- cholecystitis;
- cholelithiasis;
- pancreatitis;
- colitis;
- diabetes mellitus;
- bronchial asthma;
- atopic dermatitis.
Chronic fatigue, nervousness and anxiety, hyperactivity in children, anemia, brittle nails and hair, problem skin, headaches, appetite disorders, decreased immunity - these can be signals of actual parasitosis.
If not treated...When parasites stay in the human body for a long time, the immune system suffers a lot.In the process of the continuous struggle with foreign antibodies, it comes to exhaustion, that is, to the development of the lack of secondary immunity.
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 impaired;
- Protection against cancer of the body suffer.
How were you saved before?For thousands of years, people, eating mainly plant foods, took with them natural antimicrobial, antiparasitic and antiviral active substances.Reducing the consumption of wild plants, fruits, berries, replacing them with cultivated vegetables and fruits, thermal and industrial processing have 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 drug industry that produces antibiotics has led to a decrease in anti-parasitic immunity.
Traditional medicine for the elimination of parasites in the human body
Medicinal synthetic anthelmintic drugs have their pros and cons.There are three main negative factors:
- often affect only gastrointestinal forms of parasites;
- very toxic to the human body;
- cause many negative reactions.
Science does not stand still!Intensive scientific research into the antibiotic properties of plants is being conducted all over the world.In terms of effectiveness, they are not inferior to synthetic antibiotics, but they do not cause side effects that are characteristic of synthesized drugs.The healing components of plants are complex natural phytoncide complexes that can cleanse the human body of many parasites at different stages of their development.
Nature!This is what will help us!Herbal preparations 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 fighting parasitosis is herbal products.
