parasites(from Greek parasitos - parasite, parasite) - lower plant and animal organisms that live outside or inside another organism (host) at its expense.
parasitesIt arises in the historical process of the development of organisms from free forms of life.
Their adaptation to certain living conditions led to the simplification of tissues, the development of specialized fixed organs, the enhancement of reproductive organs and anoxic respiration, which allowed them to survive in an oxygen-free environment.
Many parasites include:
- worm;
- Fungi;
- Virus;
- protozoa;
- worm;
- Crustaceans;
- arachnids;
- insect.
The host of the parasite can be:
- bacteria;
- protozoa;
- plant;
- animal;
- human beings.
Parasites go through a complex developmental cycle: sometimes they need to change 2-3 hosts, with the organism in an intermediate state (the worm passes through the larval stage) or in the final state (the worm becomes sexually mature, becomes invasive).
Classification of parasites
According to the distribution of parasites, they can be divided into:
- everywhere- found everywhere.
- tropical- Common in tropical climate areas.
Based on biological and epidemiological characteristics, parasitic diseases are divided into:
- geohelminths- A disease in which parasites (worms) first grow in the human body and then on non-living substrates (usually underground).
- Biological helminthiasisIt is a disease in which the biological development cycle of parasites (worms) must occur in organisms other than humans.There are definitive hosts, in which the parasite develops to sexual maturity, and intermediate hosts, in which the parasite is in the larval stage or reproduces asexually.Humans are usually the final host and rarely the intermediate host.
- contact helminthiasis- Disease in which parasites are released from a mature or nearly mature human body, thus making it possible to infect another person or reinfect him (autoinfection, reinvasion).
Depending on the location of the parasite in the human body:
- intraluminal parasites- Those that live in the intestinal lumen and other cavities of the human body (e.g. roundworms, tapeworms).
- tissue parasites- Lives in human tissue (schistosomiasis, hydatid disease).
According to the residence of the owner (person):
- ectoparasites(mosquitoes, horseflies, leeches, lice).
- internal parasites(helminthiasis):
- Roundworms (nematodes - roundworms, filarial worms, whipworms, pinworms, Strongyloides, hookworms, Trichinella spiralis);
- Flatworms:
- Flukes (trematodes - felis fluke (Opisthorchis), Clonorchis, Fasciola, Schistosoma);
- Tapeworms (Tapeworms - bovine and pork tapeworms, dwarf tapeworms, broad tapeworms, Echinococcus tapeworms).
- bacterial disease(Leptospira, Staphylococcus, Streptococcus, Shigella).
- protozoa or protozoa(Amoeba, Lambella, Trichomonas, often host to Chlamydia and HIV).
- Fungal diseases(Mycoses) - Candida, Cryptococcus, Penicillium.
How parasites enter the body
You can contract parasitic diseases not only through dirty hands.Animal fur is a vector for the eggs (roundworm and toxocara) of Giardia.
Pinworm eggs that fall from wool can survive for up to 6 months and enter the food tract through dust, toys, carpets, underwear, bedding and hands.
dogThrough moist breath, it can spread its eggs up to a distance of 5 meters (cats - up to 3 meters).
fleaDogs also carry the eggs.Roundworm eggs enter the body through unwashed vegetables, fruits, berries, herbs, dirty hands and are also spread by flies.
And improperly prepared kebabs or homemade lard are the routes of infection for trichinellosis; salted fish, caviar or "stroganina" - opiodiasis and taeniasis.
So, there are several ways for parasites to enter the human body:
- nutritious(via contaminated food, water, dirty hands);
- contact family(via household items, infected family members, pets);
- transmission(via blood-sucking insects);
- transdermal,or active (larvae enter the body through skin or mucous membranes when in contact with contaminated soil, while swimming in open water).
Adaptive properties of parasites:
- Long life expectancy (worms can live in the human body for many years, sometimes as long as the parasite owner lives);
- The ability to suppress or modify the immune response of the host organism (the emergence of a state of immunodeficiency, creating conditions for the penetration of external pathogens and the "de-suppression" of internal infectious foci);
- Many types of worms secrete anti-enzymes when entering the digestive tract, which save them from death; the digestive process is disrupted, toxic allergic reactions of varying severity occur: urticaria, bronchial asthma, atopic dermatitis;
- Developmental stages (eggs, larvae, host changes);
- The ability of eggs to survive in the external environment for many years;
- Sexual reproduction, during which the exchange of genetic information occurs, is the highest stage of development and leads to an increase in heterogeneous populations, that is, the parasite becomes less vulnerable;
- Lack of immunoprophylaxis methods because immune responses are weak and unstable;
- Worms are widespread and occupy many habitats (water, soil, air, plants and animals).
Epidemiology of parasitic diseases
Due to increased migration processes, the diversity of helminths that inhabit the human body has increased significantly.Currently, of the more than 260 species of existing parasites, 70 are common.There is an increasing trend in infections with enteriasis, giardiasis, toxocariasis, opiodiasis, dilobidiosis, tendinosis and echinococcosis.Schistosomiasis and filariasis are common in countries in Southeast Asia, Africa, and Latin America.
"Healthy" people...Many people who lead a healthy lifestyle experience health problems due to the presence of parasites in their bodies.Improving physical health (proper nutrition, physical exercise, strengthening programs) without removing parasites from the body does not produce significant positive results.
They are everywhere...According to the World Health Organization (WHO), worms and other types of parasites are found not only in the gastrointestinal tract, but also in vital organs: brain, heart, lungs, liver, kidneys.
cause of many diseases
During their life, worms secrete special substances called toxoids, which are powerful poisons and allergens.Parasites (protozoa, fungi, and helminths) are the cause of many chronic diseases:
- cholecystitis;
- cholelithiasis;
- pancreatitis;
- colitis;
- diabetes;
- bronchial asthma;
- Atopic dermatitis.
Chronic fatigue, irritability and anxiety, ADHD in children, anemia, brittle nails and hair, skin problems, headaches, loss of appetite, reduced immunity – these may be signs of a current parasitic disease.
If not treated...When parasites remain in the body for an extended period of time, the immune system is greatly affected.In the constant struggle against foreign antibodies, exhaustion occurs, that is, the development of secondary immune deficiencies.
Parasitic diseases can cause:
- Vitamin deficiencies and depletion of trace elements: potassium, copper, manganese, selenium, zinc, magnesium, silicon;
- Hematopoietic system diseases;
- hormonal imbalance;
- Impaired vascular permeability;
- The body's cancer-fighting defenses are compromised.
How were you saved before?For thousands of years, people have mainly eaten plant-based foods and have also obtained natural active substances that are antibacterial, antiparasitic and antiviral.Reducing the consumption of wild plants, fruits, berries and replacing them with cultivated vegetables and fruits, thermal and industrial processing leading to a reduction in the consumption of natural phytobicides and antibiotics.As a result, humans are easy prey for many microorganisms.Intensive development of the pharmaceutical industry for the production of antibiotics has led to a decrease in antiparasitic immunity.
Traditional medicine to eliminate parasites from the human body
Medicinal synthetic anthelmintics have their advantages and disadvantages.There are three main negative factors:
- Usually they only affect gastrointestinal forms of the parasite;
- Very toxic to humans;
- Cause many adverse reactions.
Science doesn't stand still!Intensive scientific research into the antibiotic properties of plants is ongoing around the world.In terms of efficacy, they are not inferior to synthetic antibiotics, but do not cause the side effects characteristic of synthetic drugs.The therapeutic components of the plant are complex natural phytobacterial complexes that eliminate many parasites from the human body at different stages of development.
nature!This will help us!Preparations of plant origin are much less toxic; if necessary, they can be prescribed in long-term courses; they activate anti-parasitic immunity and effectively inhibit the vital activity and reproduction of parasites in the human body.
Parasitic diseases are widespread diseases that have toxic and devastating effects on the human body.Since chemical drug treatments can have a negative impact on the body, the best solution to combat parasitic disease problems are herbal products.
