Parasites in the human body

28 April 2025

Human parasites are parasites whose infection is subject to a person. The general definition of the word "parasite" applies not only to multicellular and protozoa, living at the expense of their owner and at the expense of the latter, but also viruses, bacteria and mushrooms with similar properties. According to historical tradition and in terms of medical parasitology, it is customary to call any creatures that lead to a parasitic lifestyle, except for viruses and bacteria with similar properties. Pests in the body

Pests include many helminths, fungi, viruses, protozoa, worms, crustaceans, spider -shaped, insects. Pest owners can be bacteria, simpler, plants, animals and humans. Pests undergo a complex cycle of growth: sometimes they need a change of 2-3 owners whose body is intermediate (the Elminths go through the larvae) or the finals (the helminths become invasive).From the story:The study of pests in ancient people is based on the study of feces and other fossilized materials. The first pests found in humans were the Paragonimus Westermani eggs from northern Chile, discovered in hardened stools and dating about 5900 BC. In Brazil, hookworm eggs were also found from 5000 BC, in Peru - Nematod eggs from 2330 BC. And Egyptian mummies dating from 2000, 1250 and 1000 years. Eg MI. They contained a resolution egg, along with a well -preserved female worm. In Berlin, for the period 1866-1875. 16% of all open falls contained worms. The Taurus Taeniarhynchus saginatus was particularly widespread where the raw cattle meat was eaten. In St. Petersburg, according to Kessler, 3, 66 % of the persons investigated by him suffered from this parasite (1888). Pork Tekenia (Taenia Solium) is located everywhere in areas where they eat raw or semi-water pork meat. In St. Petersburg in the late 19th century, about 3 % of the population suffered from this parasite. When they began to avoid the use of raw meat, the percentage of diseases decreased greatly, for example, in Denmark from 53 % to 20 % for 10-12 years. Dypilidium caninum lives in the guts of dogs and cats and rarely in children's intestines. Cases of infection of children in the late 19th century were known from England, Germany, Denmark: infection occurs exclusively when the fleas swallowed. Their parasites and their exemption(The products of their lives) are the strongest poisons for the human body. They cause severe acidification and thickening of the blood and the entire internal environment. Cause the most serious health disorders. From bronchitis to oncology. Destroy a person's soul, deprive peace and sleep. In the child's body, parasites prevent the normal development of the nervous system of the child and, with a long power disease, contribute to mental and physical retardation.ClassificationBy distribution: Geographical pencils

Ubiquette - Get to know everywhere.Tropical - distributed in tropical climate zones. In biological and epidemiological characteristics:GeoHelminths is a disease in which helminths are initially developed in the human body and then on a non -lively substrate, more often on earth.BioHelminths is a disease in which a biological cycle of helminth development should be performed on the body of other living beings except one person. It distinguishes among the final owners, in the body whose helminths develop at the sexually mature stage, as well as intermediate, where the parasite is in the larvae or reproduction stage is not sexually. A person is more often the final owner, less often - intermediate. Helminthiasis of contact is a disease in which parasites are distinguished by the human body mature or almost mature, as a result of which another person is infection or re -infection of the same (automatic invasion, reappearance). Depending on the location of the parasite in the body:Enlightenment - living in the cavity of the intestinal and other cavities of a person (for example, ascids, ribbons).Fabric - living in fabrics (Sistematis, ehinokokkoz). To the place of residence to the owner:External: mosquitoes, blind, leeches, lice.Internal(Helminthias):Round worms(Nematodes - Ascarids, Filaria, Vlasov, Pinworms, Strungyloids, Ancylostomidae, Trichinella).Flat worm:Trematodes (Cat Bickelter (Opisthorchis), Cloner, Fasciola, Schistosomes).Cestodes (Worm Ribbon - Taurus and pork film, dwarf tan, broad movie, echinococcus). Bacteria(Leptospira, Staphylococcus, Streptococcus, Shigella).Protonment(fees, Giardia, Trichomonas, often the owners of chlamydia and AIDS virus).Fungi(fungal diseases) - Candida, Cryptococcus, Penicillium. Ways of infection with helmets

How do pests enter the body?Parasitism can be contaminated not only through dirty hands. Animal hair is a worm carrier (Ascaride and Toxocara), Lamblia. Five eggs that have fallen from wool remain viability for up to 6 months and with dust, toys, rugs, lingerie and bedding and their hands fall on the food. A dog via wet breathing disperses the eggs at a distance of 5 meters (cat up to 3 meters). Dog fleas also tolerate worms eggs. Askarid eggs enter the body through poorly washed vegetables, fruits, berries, green, dirty hands and also spread to flies. And incorrectly cooked barbecue or homemade Lardy is the course of trichinella infection. Poor salted fish, caviar - rear and wide film. So there are several ways to enter the body:(through contaminated foods, water, dirty hands).Contact-Household (through household species, from infected family members, pets).Contagious (through insects that dissolve blood).Transdermal or active (in which the larva penetrates through the skin or mucous membranes during contact with contaminated soil when swimming in open tanks). Parasite symptomsIt is not necessary for the infection to manifest a bit at all. Sometimes a person feels healthy, despite the invasion, thanks to strong immunity. Some individual time will be healthy. Subsequently, therefore, the disappearance of immunity (can occur at any time, surgery, disease) - quiet Parasite signals will begin to serve. It is urine with smell, acne on the skin, stubborn cough with pure lungs, unstable stools with intense odor or constipation, gas formation, unpleasant oral odor. The most specific manifestation of the presence of helminths in the body is Bruxism (tooth nightclub). Night sauce, ordinary nausea, distortion of night hunger appetite, vague hunger, sweet and acidic addiction and air will. Children have a decrease in appetite or electoral appetite. Sometimes people are found with increased appetite, but at the same time lose weight. General signs of parasitic invasionsConstipation, stagnation of bile Allergy

Some worms, due to their shape and large sizes, can mechanically close the bowel lumen, bile duct conductors, which leads to the worsening of the peristaltic, the formation of constipation, complete or partial intestinal obstruction. Hlybon's invasion can cause the common biliary conductor to obstruct, which leads to difficulty in biliary, mechanical jaundice.DiarrheaSome pests, especially protozoa, produce substances similar to prostaglandins, which lead to sodium and chloride in loss, which in turn cause diarrhea - frequent water movements.Gastric and intestinal discomfort syndromePests living in the upper intestine cause inflammation and lead to intestinal interruption, bloating. This leads to a reduction in the absorption of nutrients. As a result, the fats that need to be absorbed into the small intestine fall into the colon, causing cramps, alternating constipation and diarrhea.Joint pain and musclesPests can move around the human body to settle in the most convenient parts, for example, joints and muscles. Inflammation of the fabric is the result of their parasites injury or the body's immune response to their presence. At the same time, a person experiences muscle and joint pain. AllergyPests can disrupt the normal permeability of the intestinal mucosa, which increases the risk of penetrating large non -formulated food particles into them. This activates the body's immune response - the level of eosinophils - our body's blood protective cells, which contribute to the development of allergic reactions, are increasing. Pests cause increased production from the body of immunoglobulin E, which enhances allergic reactions.Troubled skinIntestinal parasites can cause allergic skin reactions - atopic dermatitis, urticaria, eczema. Most of the time, inflammatory changes in the skin may be the result of the presence of protozogy microorganisms (Lamblia, mushrooms) and opisthorchis.Change body weightWeight fluctuations (both than normal and less) can be the result of a parasitic disease. The weight reduction is due to the fact that digestion is impaired in the body, since there is an "internal consumer". Obesity is also a consequence of the "robbery" of the human body with a helminth invasion. The feeling of hunger occurs with a sharp drop in blood sugar due to the activity of helminths, their toxic effects on the body. AnemiaMany types of intestinal helmets are associated with the intestinal wall, harm it, causing sufficiently greater blood loss, which leads to anemia.Nervousness, sleep disorderThe toxic substances of the vital activity of pests irritate the central nervous system, causing increased concern and nervousness. Frequent awakening in the middle of the night, especially between 2 and 3 hours, is also the result of the body's efforts to get rid of toxic substances through the liver."Chronic fatigue syndrome""Chronic Fatigue Syndrome" involves weakness, reduction and fever, emotional instability, loss of concentration and bad memory. These symptoms may be the result of anemia, poisoning, lack of nutrients in the body caused by parasites.Having discovered your family members with various symptoms, they are diagnosed for parasitism and conduct a course of preventive treatment.

DiagnosisRecently, the presence of pests was determined only by the method of testing of duodenal sound and feces using tiny studies, the purpose of which is to detect selected helminths or their fragments, eggs and larvae. The eggs and larvae of Helminths parasitic in the liver, bile paths, pancreas and duodenal were found in bile and duodenal contents. In the intestinal forms of helminths, they examined samples of feces. In the case of Paragonimoz's suspicion, the sputum was explored and the urine - the urine in the genital chistosomosis. But the credibility of these studies depends on the professionalism of workers - or the workshop assistant will notice in the microscopic examination of the pests. In addition, if the parasite does not postpone the eggs at the time the check is carried out, its presence will be unnoticed even with high qualifications of the assistant laboratory. Often only with 8-10 attempts you can get a positive result. Today, there are immunological studies that allow you to identify the blood of an infected person the presence of antigens and antibodies in parasites of various species. The reliability of such analyzes depends on the life cycle of pests and their quantity in the body.The most vulnerable to the effects of pests are children. They are contaminated with various types of pests through dirty hands, sand, soil and water. Sometimes the child's infection can occur in an endometrial, since the simplest, bacteria, viruses, Candida and Helminth larvae can penetrate the fetus through the placenta with blood flow, as well as during birth through the birth channel.Do not risk the health of your children, conduct preventive removal lessons.
