Parasites in the human body

28 April 2025

Parasites in humans are parasites, infections in which one person suffers. The general definition of the parasite word, not only applies to multicellular and primary animals, living at the cost of their owners and is detrimental to the latter, but also the virus, bacteria and fungi with similar qualities. According to historical traditions, and from the perspective of medical parasites, it is common for any organism to lead the parasite lifestyle, except for viruses and bacteria with similar qualities.

The parasite includes many helminths, mushrooms, viruses, protozoa, worms, crustaceans, insects, insects. The parasite owner may be the bacteria, the simplest, plants, animals and humans. The parasite undergo a complex development cycle: Sometimes they need to change 2-3 owners whose body is intermediaries (helminths that pass larval stages) or final (helminths become invasive).

From history:Research on parasites in ancient people based on stool research and other petrified materials. The first parasites found in the man is Paragonimus Westermani eggs from northern Chile, discovered in hard stool and dating back to 5900 BC. e. In Brazil, the hook eggs from 5000 BC were also found. e. , in Peru - Nematodalic eggs from 2330 BC. e. And Egyptian mummies dates from 2000, 1250 and 1000 years. BC. e. They contain a soliter egg, along with a well -preserved female worm.

In Berlin, in the period 1866-1875. 16% of all open corpses containing worms. Bull ThonLy (Taeniarhymchus Saginatus) is especially popular where raw cattle meat is eaten. At St. Tekenia pork (Taenia Solium) is found everywhere in areas where they eat raw pork or sell rad. At St. Petersburg in the late 19th century, about 3 % of the population had this parasite. When they start to avoid the use of raw meat, the percentage of diseases has decreased extremely, for example, in Denmark from 53 % to 20 % in 10-12 years. Dypilidium caninum lives in the intestines of dogs and cats, and rarely in the intestines of children. Cases of child infections in the late 19th century are known from the UK, Germany and Denmark: Infections occur monopoly when fleas swallowing.

The parasitic and their discharge(Products of their lives) are the most powerful to the human body. They cause serious acidification and thicken the blood and the entire internal environment. They agitated the most serious health disorders. From bronchitis to cancer. Destroy a person's psychology, deprive peace and sleep. In the child's body, parasites prevent the normal development of the child's nervous system and, with a long -term disease, contributing to mental and physical backwardness.

ClassifyBy distributing:

Ubiquette - Meet everywhere. Tropical - distributed in tropical climates. About biological and epidemiological characteristics:

Geohelminths is a disease in which helminths develop for the first time in the human body, and then on the non -living substrate, more often on Earth. Biohelminths is a disease in which a biological cycle of helminth development must take place in the body of other creatures, except for one person. Distinguish between the final owners, in the body that helminths develop to the stage of sexual adulthood, as well as intermediaries, in which parasites are at the stage of larvae or its reproduction is not sex. A person is usually the last owner, less often - intermediaries. Contacting helminths is a disease in which parasites are distinguished from adult or almost mature body, due to the possibility of others infection or re -infection (automatically invasive, invasive). Depending on the localization of the parasite in the body:

Enlightenment - Living in the cavity of a person and other cavities of a person (for example, ascarides, ribbons). Fabric - Living in fabric (Sistematis, Ehinokokkoz). At the place of staying with the owner:

Outside: Mosquitoes, blindness, leeches, lice. Internal(Helminthias):Roundworms.Flat worms:Trematodes (Cat Bickelter (Opisthorchis), Cloner, Fasciola, Schistosome); Cestodes (ribboned worms - tapeworm and pork, dwarf leather, broadband, echinococcus). Bacteria(Leptospira, Staphylococcus, Streptococcus, Shigella). Protect(Amoebas, Giardia, Trichomonas, usually the owner of Chlamydia and AIDS virus). Mycoses(Fungal disease) - Candida, cryptococcus, penicillium. How to infect with helmets

How does the parasitic penetrate into the body?Parasites can be infected not only through dirty hands. Animal hair is a worm (Ascaride and Toxocara), Lamblia. The egg worms of the battery have fallen from wool still exist for 6 months and through dust, toys, carpets, underwear and beds and hands falling into the road. A dog through a wet breath disperses eggs at a distance of 5 meters (cats - up to 3 meters). Dog's fleas also withstand deep eggs. Askarid eggs penetrate the body through vegetables, fruits, berries, green vegetables, dirty hands and also spread to flies. And incorrect cooked cooked meat or homemade pork fat is a trichinellosis infection; Poor salted fish, caviar - Opisthorchi and broadband.

Therefore, there are several ways to enter the body:

Eating (through foods infected, water, dirty hands); contact with households (through family goods, from family members infected with diseases and livestock); Cannot transmission (via blood insects); through the skin, or active (in which the larvae penetrate through the skin or mucous membrane while in contact with infected soil, when bathing in open tanks). Symptoms of parasitesNot all necessary but infection somehow manifests itself. Sometimes a person feels healthy, despite the invasion, thanks to strong immunity. Some time he personally will be healthy. After that, the extinction of immunity (incidents can occur at any time stress, surgery, disease) - The quiet signal parasite will start to serve. This is a smelled urine, acne on the skin, coughing with clean lungs, unstable stool with spicy or constipation, forming gas, unpleasant odor from the mouth. The most specific manifestation of the presence of helminths in the body is the Bruxism (Ranging of the Rang). At night saliva, common nausea, the depravity of night cravings, irreversible hunger, sweet and acidic food addiction, and air belching. Children have reduced appetite or appetite. Sometimes people who have increased appetite are found, but at the same time they lose weight.

General signs of parasitic aggressionConstipation, stagnation of bile

Some worms, due to their large shape and size, can close the intestines of the intestine, the ducts of the bile tract, leading to a decline in peristalsis, constipation formation, partial or partial congestion. The invasion of Hlybon can cause congestion of conventional bile ducts, leading to difficulties in the flow of bile, mechanical jaundice.

Diarrhea

Some parasites, especially primary animals, produce substances similar to prostaglandin, leading to sodium and chloride to lose, therefore, causing diarrhea - regular intestinal path.

Stomach and intestinal uncomfortable syndrome

The parasites living in the upper intestine causes inflammation and leads to the disruption of the intestine and flatulence. This leads to reducing nutrient absorption. As a result, fats should be absorbed in the small intestine falling into the colon, stimulating cramps, alternating constipation and diarrhea.

Joint pain and muscles

Parasites can move around the human body to settle in the most convenient places, for example, in joint liquids and in muscles. Fabric inflammation is the result of injuring them with parasites or immune reactions of the body for their presence. At the same time, a person experiences muscle and joint pain.

Allergy

Parasites can break down the normal permeability of the intestinal mucosa, increasing the risk of penetrating into large food particles that are not deformed into them. This activates the body's immune response - the level of eosinophilia - the protective blood cells of our body, contributing to the development of allergic reactions, increasing. The parasite causes increased production by the body of Immunoglobulin E, which enhances allergic reactions.

Skin problem

The intestinal parasite can cause allergic skin reactions - atopic dermatitis, urticaria, eczema. Typically, skin inflammation changes may be the result of the presence of primeval animal microorganisms (Lamblia, mushrooms) and Opisthorchis.

Change body weight

Weight fluctuations (both more than usual and less) may be the result of a parasitic disease. Losing weight is due to the fact that digestion is weakened in the body, because there is a "internal consumer". Obesity is also the result of the "robbery" of the human body with the next invasion. The feeling of hunger occurs with a sharp decrease in blood sugar due to the activity of helminths, their toxic effects on the body.

Anemia

Many types of helminths are attached to the intestinal wall, damaging it, causing greater enough blood loss, leading to anemia.

Anxiety, sleep disorders

The toxic substances of the important activity of parasites irritate the central nervous system, causing anxiety and anxiety. The regular awakening in the middle of the night, especially from 2 to 3 hours, is also the result of the body's efforts to remove toxic substances through the liver.

"Chronic fatigue syndrome"

"Chronic fatigue syndrome" includes weakness, reduction and fever, emotional instability, distraction and bad memory. These symptoms may be the result of anemia, toxicity, and lack of nutrients in the body due to parasites.

After discovering your family members about some symptoms, undergo diagnosis of parasites and conducting a preventive treatment process.

DiagnoseRecently, the presence of parasites has only been determined by the duodenal audio test method and feces by microscopic studies, its purpose is to detect chosen helminths or pieces, eggs and larvae. Eggs and larvae of parasitic helminths in the liver, bile, pancreas and duodenum are found in bile and duodenum content; In the intestinal form of helminths, they checked the feces; In the case of suspected paragonimoz, sputum has been studied and urine - urine on cell fertilizer. But the reliability of these studies depends on the professionalism of the staff - whether the laboratory assistant pays attention in checking the microscope of the parasite. In addition, if the parasitic does not postpone eggs at this time when the check is done, its presence will not be noticed even at the high level of the laboratory assistant. Normally with only 8-10 times, you can get positive results.

Today, there are immune studies that allow you to determine the blood of a person infected with the presence of antigens and antibodies to parasites of all kinds. The reliability of such analysis depends on the life cycle of the parasite and their number in the body.

Those who are most vulnerable to the effects of parasites are children. They are infected with many types of parasites through dirty hands, sand, soil and water. Sometimes, the child's infection may occur in the uterus, because the simplest, bacteria, viruses, Candida and Heelminth larvae can penetrate the fetus through the placenta with blood flow, as well as during birth through the tube.

Do not risk your child's health, take preventive worms courses.
