Studies in the field of parasitic medicine are reported by alarming facts. More than 90% of all age categories of the population are affected by helminthic invasion, or have a hidden form of carriage of various parasites. They cause many problems, causing various diseases that prevent the normal life of a person. Choosing the habitat - the human body, parasites can practically spread to all organs and systems, causing pathological changes in them and violating the function of their work.
The main types of parasites in the human body
The group of parasites that made their habitat of the human body include the simplest microorganisms, round and tape worms:
- Speakers. These are small parasites (long, no more than one and a half cm), which are transmitted to the domestic way, or in contact with an infected person. Very often, flies that carry the larvae of these worms-parasites are to the carriers of this helminthic invasion. Once on the products, they stay there for a long time, and if they are not processed, then they enter the human body. Propagating in the human body, they cause Enterobiasis. Most often, children of preschool and school age are subject to this type of disease. Enterobiasis lesions in children and adult population can reach up to 90 percent. The habitat of these parasites is the segments of the blind, the coloner of the intestine. This type of parasites does not breathe air; oxygen is not required for its existence. The nutrients for it are the contents of the intestines. After mating, which occurs in the ileum of the ileum, crawling out of the anus, the female lays down the larvae in the area of the sphincter of the anus. The biggest danger that Enterobiasis is highly contagious. Parasites are very easy to infect with the slightest deviation from individual hygiene norms.
- Askarids. Belong to the class of round worms. Parasitized in the small intestine. Call ascariasis. The source of infection is a sick person or animal. Infection occurs through food, not washed hands. Cysts of worms of parasites, falling into the soil, ripen to the level of larvae, they are dangerous for humans. If a person has previously used unwashed fruits or vegetables, the body is infected. This is also facilitated by unsanitary conditions of residence, insufficient heat treatment of food.
- Ankylostoma. They lead to the development of the pathological process in the body. This is a small parasite, which reaches no more than 2 cm in its length. Most often, small children are infected (especially in rural areas, due to barefoot).
- Wide tape. Belongs to the group of strip worms, has 12 varieties. The main parasitization site is the intestine department. The main path of infection of the body occurs when fish (which did not pass sufficient heat treatment), or through objects that were used to cut meat (knives, cutting board). This type of parasites feeds on all beneficial substances that a person uses. Its length can reach 15 meters.
- Bull and pork. These are tape worms, the length of which is 10 meters. When infected with spores of the bull tapeworm, tusiarinchosis develops, and in the case of pork chain larvae, the Taeniasis disease develops, its larval stage is referred to as cystiracosis. The development of such pathologies is most often facilitated by eating, poorly processed meat. But sometimes infection can occur through unwashed hands, and food. As a rule, in the small intestine of the body, when infected with this disease, one strip worm lives. In some cases, the duration of its existence can last up to 20 years. Since, with the help of its hooks, which are located on the parasite head, it is tightly attached to the wall of the small intestine. And therefore, sometimes difficulties arise for its withdrawal.
- Echinococci. These are tape worms up to 8 mm long, they can cause a disease called echinococcosis. The disease is often found in animals (cats, dogs, foxes, wolves). It should be noted that the human body, for echinococcal pathology, is an intermediate place of residence. The process of infection occurs during direct contact with the animal, or when cutting it. This type of disease is most affected by the rural population engaged in animal husbandry. The disease very often occurs without symptoms, and in the case of their manifestation, cystic formations occur. To remove them, it is necessary to use only the surgical method.
- Lamblia. Lead to the development of lambliosis. Parasites belong to the Zhgutikov class, are representatives of the Demolomonadide detachment. A favorite habitat is a small intestine of a person or animals. Sometimes they can affect the digestive system of birds. Infection occurs in two ways: sometimes there is infection through the respiratory tract. Cysts enter the body through the lungs, along with inhaled dust, the clinical picture in this pathology can be disguised as other diseases. And is accompanied by the development of diseases of the nervous, heart, endocrine system.
- Parasitic mushrooms. They are able to cause different pathological conditions in the human body (actinomycosis, lichen, microsporia, trichophytosis, favus, erytrazm). They live on the human body, affecting the skin, hair, nail phalanxes.
- African malaria parasites.This group includes malarial plasmodians. They are able to cause malaria. This disease is transmitted only through mosquitoes. For our area, this disease is uncharacteristic. She is subject to people living in the southern countries. Such an infectious disease can develop when visiting these countries. A feature of this disease is that local residents have the opportunity to get much lower than tourists. This is due to the fact that they develop immunity.
The infection is based on several basic ways:
- Fecal-oral. The use of unwashed vegetables and fruits, not boiled water.
- Percous. With this type of infection, the larvae of helminthic invasion fall through the pores of the skin.
- Contact-household, through everyday household items, or in contact with the infected.
A feature of all forms of helminthic parasites is that they eat at the expense of their owner (person or animal), while he selects useful nutritional ingredients (glucose, useful micro and macroelements, carbohydrates). As a result of such a pathological effect, the body begins to experience an acute lack of potassium, magnesium, zinc, silicon, selenium, as well as many vitamins. Another feature of these parasites is a high degree of adaptation. They adapt to the working conditions of the owner's body. And they are made invisible to the immune system.
The causes of infection with the human body parasites
Among the ways of infection, the following can be distinguished:
- Eggs and larvae of parasites penetrate the body when using dirty, unpeeled water. Or when eating food (fish, meat, canned food), which have not received sufficient heat treatment. This is also facilitated by eating unwashed vegetables and fruits.
- Eggs and helminth cysts remain on the surface of the skin with direct contact with everyday objects (door handles, money, toys, staircases). In addition, the source of infection may be contained in the ground, when contacting the soil, spores of parasites fall on the hands. And if they are not thoroughly washed out, then this also creates a risk of threat of infection of the body with various kinds of helmets. Therefore, the hands must be washed not only before eating, but also several times during the day, especially if there is contact with the soil.
- Various insects (flies, wasps, fleas) create a real threat of infection with worms. For this, the insect does not have to make a bite. It is enough that they, sometimes freely penetrate the dwelling, and sit on food, cutlery, leaving on them spores of the larvae of the worms of parasites.
If everyday work consists in direct contact with animals (veterinarian, rural resident, livestock), the probability of the disease increases significantly.
The main signs and symptoms of parasites in the body
A very important role in the appearance of the first signs and basic symptoms with the development of helminthic invasions is occupied by their location and abilities in the human body. Most often, they settle in the upper parts of the small intestine (wide tape, bull and pork chain, ascarides).
Vlasov, for his habitat, chooses the segment of the large intestine. Opistorchosis affects the biliary tract of the ducts. The pinworms are located in the lumen of the colon and rectum. Serious dangerous diseases may appear:
- Soreness during urination.
- Adenomatous growths.
- An irregular, painful menstrual cycle.
- The appearance of hepatitis and dermatitis.
It is very important to pay attention to the above symptoms. Despite the fact that, at first glance, they seem harmless, in fact, such signs can indicate the presence of parasites in the body.
Symptoms that appear when parasitizing the body are often perceived by patients as the presence of any other disease that is not associated with the appearance of worms. This is a great difficulty in making an accurate diagnosis. The main symptoms in the development of parasitic worms in humans:
- Violation of the act of defecation (constipation). It appears due to the fact that the accumulation of worms makes it difficult to pass the feces on the intestinal lumen.
- Sometimes diarrhea is observed. This is due to enhanced production of Ferminas (hormone-like substance, produced in the body of parasites), and leads to an imbalance of chloride ions. What explains the cause of the diarrhea.
- Increased gas formation.
- There is a violation of processing and assimilation of lanolin (fat). This is due to the fact that by parasitic in the lumen of the small intestine, parasites cause inflammatory diseases of the intestinal mucosa.
- Arthralgia and muscle pain occur.
- As a response of the body, manifestations of allergies arise, sometimes in the form of urticaria.
- Perhaps the development of ulcerative eczema, skin dermatitis, the appearance of tumors.
- In the case of the development of helminthiasis, which feeds on blood elements, iron deficiency anemia is possible.
- With a clinical blood examination, a small amount of red blood cells, a reduced hemoglobin level, and a decrease in color indicator are noted.
- Very often, granulomas of the abdominal or uterine cavity, in the lungs and liver.
- The psychoemotional state of the patient is impaired, which is expressed by unreasonable aggressive conditions, increased excitability.
- Due to severe itching in the anus, night sleep is disturbed.
- At night, the patient has a rattle of teeth (bruxism).
- The lack of choline, vitamins, amino acids, proteins and carbohydrates leads to the development of chronic fatigue, a breakdown of forces.
- The constant feeling of hunger, the development of symptoms of anorexia.
- The disease of the heart muscle, heart rate failure.
- In severe cases, the development of oncopathology.

Not only the type of parasite that has settled in the human body, but also his age, gender, physical characteristics of the body, has a significant impact on the clinical picture.
With the development of the acute stage of damage by helminthic invasions, the patient has all signs of acute intoxication of the whole organism:
- Nausea, turning into indomitable vomiting.
- Hyperthermia (sometimes to high numbers 38. 9).
- Skin rashes of anorer.
- Regional lymph nodes are inflamed.
- Pathological processes in the liver and lungs are aggravated.
If such a symptoms appear, the visit to the doctor is vital
Diagnosis of parasites in the human body
For an accurate diagnosis, you must consult a parasitologist. But often in the city clinics there is no such standard unit. Therefore, you should contact a therapist or gastroenterologist for subsequent tests and further consultation of an infectious disease parasitologist. For a long time, the determination of infection with parasites was carried out only by conducting fecal tests for the presence of worm eggs, or duodenal sounding. A fence of the material of the contents of the intestine was carried out.
By introducing a probe. Such research methods do not always reveal the presence of worms in the human body. Modern diagnostic methods (ELISA tests) allow you to detect and determine any form of parasitic worms in the human body. They are based on the identification of antibodies that the body produces in response to intoxication caused by helminthic invasion. In addition, serological techniques were widely used:
- REEF.
- Ral.
- RSK.
As an additional research method, it is used:
- Endoscopic examination.
- Ultrasound.
- MRI.
- Endobiopsy.
- Establishing an accurate diagnosis using PCR.
Relatively recently, a system-synchrometer has appeared. It is able to detect endotoxins, microbial flora and tumor cells using an expanded electromagnetic range. With the help of frequency resonance therapy, you can not only diagnose, but also the effective therapy of any form of helminths turns out, regardless of where they live.
