Parasites are microorganisms that live and feed on other organisms.Parasites often cause harm to the host.It is common to divide parasites into species such as zooparasites and plant parasites.Zooparasites include protozoa, helminths, spiders, insects and others.Plant parasites include bacteria, fungi, some higher plants and others.
Viruses are also parasites.In most cases, in order to survive, the parasites have to change two or three hosts, causing exhaustion and weakening of the organism.They often lead to the death of the owner.Most parasites are the causative agents of many human diseases.In medical terminology, parasites include all creatures that lead a parasitic lifestyle.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, balantids, pneumocystis, toxoplasmas and others.For 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 goal of parasites is to hide their existence.That is, they live undetected in the host's body.Testing for parasites involves observing their release (amoeba, segments, worms, pinworms) or the products of parasite reproduction (eggs, protozoan cysts).Diagnosis is made on feces, urine, sputum or human body tissue (blood and lymph nodes).
Let's highlight the list of studies used for this:
- histological coprogram;
- histological analysis;
- immunological (serological) tests;
- microscopy (chemoscanning);
- electroacupuncture methods (ART - examination of vegetative resonance).
Histological coprogram analysis involves diagnosing thin sections of a stool sample using optical systems.It enables clear identification of body parts of helminths, their eggs and membranes (skin) of larvae.This is how helminthiasis is detected.An additional feature of this method is the determination of the type of parasites found.
A serological blood test that detects antibodies to helminths is more effective.This method is also called an immunological (serological) test.The essence of the test is the use of different sets of chemical reagents and markers.They are used to identify certain types of antibodies and parasite antigens in human blood.Immunological tests are performed only in medical laboratories.
Microscopic analysis is based on the use of dark field, fluorescent and electron microscopes.This diagnostic enables the study of living or fixed microscopic objects, as well as cellular and subcellular structures.
The method of electroacupuncture is based on the use of special devices for identifying basic data on people's health.This method examines different parts of the skin.
Histological analysis is a common method for examining stool for the presence of parasites of various species.In most cases, it is used to determine helminthic infestations in human biomaterial.It can be performed for adults and children.
Hemoscanning (blood examination) allows determining the state of the main blood elements and the purity of its plasma.When taking the parasite test, which is based on this method, the blood is not processed (that is, it is not dried or colored).Its study is carried out using a microscope, which is connected to a video camera.Then the sample of the material being studied is magnified under a microscope by 1800-2000 times.At this moment, the monitor emits the resulting image, and also provides the ability to record photos or videos.Hemoscanning allows you to get data on the state of the immune system and its activity, as well as to identify the presence of bacteria, fungi and helminth larvae.
VRT (Vegetative Resonance Test) is based on the phenomenon of biological resonance that is created between the drug and the human body.Such a drug acts as a carrier of information about the frequencies of different types of parasites.In 1989, all data on the frequency of various parasites, fungi and viruses were discovered and recorded.This type of research provides an opportunity to assess a person's condition at a given moment.That is, to determine the level of disorders of the immune system, as well as the viral and bacterial load of the human body, remove toxins, reduce the body's reactions to various antigens and allergens, and much more.
In the laboratory where ART analysis is performed, special attention is paid to determining the level of eosinophils.It is their 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 best one is determined by the attending physician.The most commonly used tests are blood and stool tests to detect different types of parasites.Among the blood tests for parasites, the following types can be distinguished:
- blood test for lamblia;
- blood test for pathogenic opisthorchiasis (IgG antibody detection);
- 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 for identifying helminths is feces.Because it is most often and easier to detect them there.
Who should be tested?
A blood test for parasites is offered to such patients who complain of a decrease in 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 occur 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 antibodies and specific immunoglobulins in the human body.They are the ones who act as parasitic markers.
In many cases, blood diagnostics are additionally carried out using the PCR (polymerase chain reaction) method.This study is considered effective and reliable.Its main advantage is the advantage of identifying many types of diseases at a time when other diagnostics are powerless.
It is also recommended to take blood for parasites in preparation for vaccination, during pregnancy and after completing a course of antiparasitic therapy.This analysis must be done several times (immediately after treatment and after one to three months).
