Parasites are microorganisms that live and feed on other organisms.Parasites often cause damage to the host.It is common to subdivide parasites into species such as zooparasites and plant parasites.Zooparasites include protozoa, helminths, arachnids, insects and others.Plant parasites include bacteria, fungi, some higher plants, and others.
Viruses are also parasites.In most cases, to live, parasites need to change two or three hosts, which causes the organism to be exhausted and weakened.They often lead to the death of the owners.Most parasites are the causative agents of many human diseases.In medical terminology, parasites include any creature that leads a parasitic lifestyle.The exceptions are bacteria, viruses and fungi.
Diagnosis of parasites in humans.
There are a number of human diseases caused by parasites such as protozoa, parasitic worms, arthropods and pathogenic microorganisms.Protozoan parasites include amoebae, leishmania, lamblia, plasmodium, trypanosomes, balantidae, pneumocystis, toxoplasmia and others.To parasitic worms: helminths.Arthropods include insects and mites.And pathogenic microorganisms include bacteria and spirochetes that parasitize ticks, fleas, lice, pathogenic fungi and viruses.
The main objective of parasites is to hide their existence.That is, they live undetected in the host's body.Testing for parasites involves observing their release (amoebas, segments, worms, pinworms) or the products of parasite reproduction (ova, protozoan cysts).The diagnosis is made in feces, urine, sputum or tissue from the human body (blood and lymph nodes).
Let's highlight a list of studies that are used for this:
- histological coprogram;
- histological analysis;
- immunological (serological) tests;
- microscopy (hemoscanning);
- electroacupuncture methods (ART - vegetative resonance test).
Analysis by the histological coprogram method involves the diagnosis of thin sections of a stool sample using optical systems.It allows you to clearly identify parts of the body of helminths, their eggs and the membranes (cuticles) of the larvae.Thus, helminthiasis is detected.An additional feature of this method is determining the type of parasites found.
More effective is a serological blood test, which detects antibodies to helminths.This method is also called an immunological (serological) test.The essence of the test is to use several sets of reagents and chemical markers.They are used to identify certain types of antibodies and parasite antigens in human blood.Immunological tests are carried out only in medical laboratories.
Microscopic analysis is based on the use of dark field, fluorescent and electron microscopes.This diagnosis allows studying living or fixed microscopic objects, as well as cellular and subcellular structures.
The electroacupuncture method is based on the use of special devices to identify basic data about the state of human health.This method examines different areas of the skin.
Histological analysis is a common method of examining feces for parasites of various types.In most cases it is used to determine helminthic infestations in human biomaterial.It can be done for adults and children.
Hemoscanning (blood examination) allows us to determine the state of the main elements of the blood and the purity of its plasma.When performing a parasite test based on this method, the blood is not processed (i.e., not dried or stained).Its study is carried out using a microscope connected to a video camera.The sample of the material being studied is then magnified under a microscope between 1,800 and 2,000 times.At this time, the monitor transmits the resulting image and also provides the opportunity to take photographs or videos.Hemoscanning allows us to obtain data on the state of the immune system and its activity, as well as identify the presence of bacteria, fungi and helminth larvae.
VRT (vegetative resonance test) is based on the phenomenon of biological resonance that is formed between the drug and the human body.This drug acts as a carrier of information about the frequencies of various types of parasites.In 1989, all frequency data for various parasites, fungi and viruses were discovered and recorded.It is this type of research that provides the opportunity to assess a person's condition at a given time.That is, establishing the level of disorders of the immune system, as well as the viral and bacterial load in the human body, eliminating toxins, reducing the body's reactions to various antigens and allergens, and much more.
In the laboratory where the analysis is carried out using the ART method, special attention is paid to determining the level of eosinophils.It is its overestimated indicator that indicates the presence of allergic reactions caused by parasitic infestations.Eosinophils are a type of white blood cell that can detoxify bacteria.They participate in allergic processes in the human body and can be dyed with acid dyes.That is, in other words, eosinophils are markers of parasitic invasions in the normal state of human immunity.
Parasite analysis: which is better?
There are many types of tests and the treating doctor determines which is best.The most commonly used tests are blood and stool tests to detect various types of parasites.Among blood tests for parasites, the following types can be distinguished:
- blood test for lamblia;
- blood test for pathogens of opisthorchiasis (detection of IgG antibodies);
- blood test for echinococcus pathogens;
- blood test for pathogens of toxocariasis;
- blood test for trichinosis pathogens;
- blood test for ascariasis pathogens.
The material for research in all of the above methods is blood, which is taken from a vein.
The research material to identify helminths is feces.Because there it is more frequent and easier to detect them.
Who needs to be tested?
A blood test for parasites is offered to patients who complain of a decline in their general health.As is known, there are hundreds of families that parasitize the human body.Many of them produce toxins that poison the blood.Some reduce the amount of nutrients.And at the same time, diseases that arise as a result of the vital activity of parasites are difficult to identify.Because the symptoms are similar to the manifestations of many diseases.A blood test makes it possible to determine the amount of specific antibodies and immunoglobulins in the human body.It is they who act as parasite markers.
In many cases, blood diagnosis is additionally carried out using the PCR (polymerase chain reaction) method.This study is considered effective and reliable.Its main advantage is to identify many types of diseases at a time when other diagnoses are powerless.
A blood test for parasites is also recommended before vaccination, during pregnancy, and after completing antiparasitic treatment.This analysis must be done several times (immediately after treatment and after one to three months).
