Parasites in the human body

Human pathogenic microorganisms

Parasites are everywhere. They cause dangerous diseases to humans-sleeping sickness, trichomoniasis, giardiasis, ass. An increase in the number of parasitic diseases is recorded every year around the world. According to clinical data from the World Health Organization, 3. 5 billion people have been infected with parasites. 70% of them are children. What are the symptoms of pathogenic microorganisms in the human body? How to get them out?

The etiology of parasitic diseases

Parasites exist and feed on living things: plants, animals, people. They can live in the host permanently or temporarily (during reproduction). The types of parasites living in humans are:

  • Ectoparasites. They live on human skin and scalp or external organs. 92% are temporary or facultative parasites (blood-sucking insects, water ches). They can exist independently of the host organism.
  • Internal parasites. They live in the internal organs and tissues of the human body.

Pathogenic microorganisms exist in all nature. They can feed on various tissues and cells. The pathogens of amoebic dysentery and chronic colitis (Entamoeba histolytica) affect the mucosa of the large intestine, causing bleeding and open wounds, called amoebic ulcers. Organs cannot function normally, and pathological changes begin to occur in the work of the gastrointestinal tract.

The simplest parasite

The main types of pathogenic microorganisms:

  • The simplest are ciliates (balworm disease), amoeba (dysentery), trypanosomiasis (sleeping sickness is caused by a parasite that can affect the central nervous system, and its name is Trypanosoma bruceiTrypanosoma). They live in the intestines and other parts of the gastrointestinal tract, causing serious intestinal infections. A person's urinary and reproductive organs.
  • Worms are the most widespread parasites in humans. Representatives: trematodes (Trematoda), tapeworms, flatworms-(Cestoda), round worms-(Nematoda), Acanthocephali (Acanthocephali). They live in a person's intestines, stomach, and lungs. It can penetrate the heart, eyes, urinary and reproductive organs. 2-3% of people live in muscles, bones, and brains.

The main method of infection:

  1. bites blood-sucking insects (mosquitoes, horse flies, and flies can spread infections to great distances).
  2. Contact with animals. According to clinical studies by parasitologists, dogs are the main asymptomatic carriers of echinococcosis.
  3. Unwashed fruits and vegetables.
  4. Non-compliance with personal hygiene rules (without washing hands before eating)-up to 86% of children under the age of 14 are affected by this infection.
  5. Drink uncoiled water from reservoirs and unverified water sources.
  6. Swimming in prohibited places. Parasites living in water bodies enter the human body through the skin or accidentally ingested. They also live in fish and shellfish (a reservoir of cattle and pork tapeworms-small pond snails).
  7. Unprotected sex-trichomoniasis.

Clinical pictures of diseases caused by parasites

The symptoms of the disease depend on the type of parasite and its location. The manifestation of the disease is affected by the patient's general health and age. A person can live with parasites in the human body for a long time without knowing their existence. As immunity declines, he will show the first symptoms of infection.

The signs of the disease start with fever, weakness and fatigue. The clinical situation of diseases caused by worms or amoeba is different.

There are 1. 5 billion people in the world suffering from nematode infections, 70% of them are children. Different types of worms cause different diseases. The main symptoms of worms parasitic in the human digestive tract are:

  • Gastrointestinal dyspepsia.
  • Human feces disorder, persistent tenesmus.
  • The first signs of hemorrhoids.
  • General symptoms of body poisoning.

Worms can affect the body's sensory system, causing eye keratitis, iritis, and conjunctivitis. In the final stage, a person is completely invisible.

The second most common disease in the world is echinococcosis. Echinococcus is a parasite in the liver that causes the following symptoms: heavy weight, pain in the right ear perichondrium, chronic fatigue, yellowing of the skin and mucous membranes. In the end stage: abdominal bleeding, sepsis and abscesses and liver cysts, which may rupture and release purulent contents into the abdominal cavity (peritonitis).

Pulmonary echinococcosis

Suffering from pulmonary hydatid disease, the patient showed signs of asphyxiation, chest pain, cough (early stage-dryness, terminal stage-suppuration, green discharge and blood). According to clinical studies and observations, adult patients develop pleurisy, inflammation of lung tissue, and peritonitis (the consequences of ruptured cysts and pus entering the pleural cavity and bronchi).

In 2% of cases, echinococcosis can affect the brain: connective tissue, which forms a dense sac around the ribbon, and there are inflammatory changes in the brain tissue membrane-glial cells around it. On MRI, multiple lesions of parasite cysts and hemorrhage were diagnosed. Hyperemia traps the membranes in the bladder area. In the initial stage, the patient complained of frequent headaches, dizziness, vomiting, tremors of the limbs and seizures. At the terminal, paresis of the lower or upper limbs appears. The patient was diagnosed with mental and neurogenic personality disorders: irritation, manic depression, dementia.

Among the fish in the river, fish, perch, pike, and tapeworm (banded worms) live, which can cause human double flagellosis. The disease remains asymptomatic in the intestine of the rectum for a long time. Symptoms are diagnosed against the background of reduced immunity or deterioration of chronic diseases. Patients experience loss of appetite, nausea and vomiting, abdominal pain, unstable stools, persistent tenesmus, weakness, fatigue, and paresthesias in the lower limbs. In allergies, rashes and pimples appear on the skin. In the final stage, the patient was diagnosed with B12-anemia. Anisakids live in sea fish-herring, cod, pollock, salmon, perch. They provoked the development of anisic acidosis. The symptoms of this disease are similar to those of double flagellosis.

Parasites can cause venereal diseases and infectious diseases. In countries around the world, 250 million people are infected with trichomoniasis every year. Clinical symptoms of trichomoniasis:

  • Congestion and edema of the vaginal mucosa.
  • Burning and persistent itching.
  • Pain when urinating.
  • Pain during sex.
  • Dark green with blood and mucus in the vagina.

Trichomoniasis is dangerous for pregnant women and children. The disease causes serious complications in embryos and newborns.

Treatment and diagnosis of human parasitic diseases

In 85% of cases, parasitic diseases start suddenly: increased body temperature, diarrhea, nausea, weakness or other symptoms. A person seeks the advice of a doctor. Doctors examine patients, collect memories, answer questions, and prescribe referral laboratories and instrumental research. The patient asks: How to treat? How to remove and eliminate pathogenic microorganisms? The treatment method depends on the type and type of parasite (protozoa, worm).

Research on human parasites

Main research:

  1. Complete blood count and white blood cell count and ESR. An increase in ESR indicates inflammation in the body. Increased number of eosinophils-used for nematode infections.
  2. Immunoassay and immune blood test.
  3. For echinococcosis, X-ray examination will be performed-examination of the chest, intestines (using contrast medium) to determine the location of the cyst.
  4. Research parasite feces, general procedures.
  5. The vaginal and cervical mucous membranes are coated with trichomoniasis.
  6. PCR-This analysis enables you to identify infectious agents with 98% accuracy.
  7. Abdominal ultrasound examination, genitourinary system.
  8. ECG, EEG.

After the examination, the doctor will write a prescription. The plan includes reducing the symptoms of the disease, destroying the parasites and removing them from the body. The patient must eat strictly. Food should be steamed or boiled. Eliminate fat, spicy and salty foods from your diet. To get rid of the infection, they use medications (prescriptions, injections, suppositories). The drug of choice for antiprotozoal infection is the antibacterial agent for antiprotozoal. Surgical treatment is only used in the advanced stages of the disease. In addition, prescribing antihistamines can reduce inflammation and swelling.

In the intestinal stage of ass worm disease, the doctor prescribed deworming medicine. The tablet can eliminate parasites and eliminate disease symptoms. Eye drops drip into the conjunctiva to kill and remove pathogenic microorganisms.

Pills alone cannot cure the disease; in addition, folk remedies and herbs are also used. The main herbs for removing worms are tansy, wormwood, marsh calamus, and fennel.

Patients suffering from biloba flagellosis and anisic acidosis should prescribe a strict treatment diet and medicinal substances to eliminate and cure pathogenic microorganisms.

For sleeping sickness, prescription drugs can help patients get rid of trypanosomiasis.

For sexually transmitted diseases, the gynecologist prescribes antiprotozoal drugs, other suppositories or vaginal tablets. Before going to bed, it is recommended to bathe with chamomile and calendula to relieve itching and burning.

Folk remedies to get rid of parasites

Consider a herbal infusion formula for repelling worms. To prepare for infusion, take 4 grams of wormwood and 5 pieces of cloves; add 2 grams of knotweed, marsh ampoort and thyme, 2 grams of lemon balm and tansy flower, 0. 5 grams of valerian. Mix well and pour in 500ml of hot water, let it brew for 12 hours, and drink it the day after eating.

Pour 5 grams of chamomile, common tansy, sea buckthorn and oak bark into hot water and place it in a warm place for 7-8 hours. It is recommended to use a thermos. To eliminate worms, drink 5 tablespoons a day after meals, 3 times a day.

In order to completely remove the worms, please use enema and herb and garlic decoction. To prepare, pour 5-6 cloves of garlic into half a cup of cold water. Bring to a boil, but do not boil. Then cool down and perform the process 2 hours before leaving the house. Along with the stool, the parasites will leave the intestines.

Using baking soda to remove worms is an uncommon and untested method. Use it to make enema and oral solution. You need to consult a doctor before performing this procedure.

It is important to remember that herbal medicine has contraindications. You should consult a doctor before using them. Main contraindications: pregnancy, childhood, gastrointestinal diseases.

With timely treatment, a person can get rid of parasites completely. The patient must follow the doctor's prescription and take the medicine correctly. After a course of treatment, he must be examined by a doctor for one year and undergo an examination.

Preventive measures

Prevention aims to prevent cysts, larvae of parasites from entering the body. The doctor will tell the patient what the worm looks like, as well as the protection methods and first aid methods for parasitic infection. Medicine has not produced vaccines and vaccines against such infections.

  • Maintain personal hygiene. People should wash their hands with soap or other disinfectant after going to the toilet, walking, handling soil and water, and before each meal.
  • Moms need to monitor and teach their children to maintain personal hygiene. Do not put dirty hands or other objects in your mouth.
  • Vegetables, berries and fruits should be washed with warm water before use. It is best to use baking soda to kill parasites and cysts.
  • The water must be boiled before drinking. Do not drink unverified water (water, river water).
  • You cannot swim in prohibited places-ponds and ponds without equipment.
  • Monitor the health of pets. Conduct a course on preventing parasites. Use drops on the wilted areas of cats and dogs as a method of preventing and first aid parasitic infections.
  • Prepare fish and meat products strictly according to technology.
  • Have a partner and avoid promiscuity.
