What parasites can live in the human body and how to properly fight them?

Before starting treatment for parasites, it is important to determine exactly which type of parasite is present in the body.This is necessary to choose an effective treatment, as most medications are specifically designed to eliminate specific types of worms.

Are worms protozoa?

Sometimes you hear this: The patient is infected with protozoa.You need to understand that protozoa are entirely single-celled microorganisms that, in extreme cases, can organize colonies.But they are never multicellular, like worms and worms.

In protozoa, all processes occur within the cytoplasm and nucleus, while in nematodes the anatomical organization is much more complex: they have differentiated organs that perform special physiological functions.Therefore, it is fundamentally wrong to classify worms as protozoa.

Sometimes worms are called protozoan parasites compared to insects (bedbugs, lice, etc.) because the latter are much higher on the evolutionary ladder.In this interpretation, the name worm as a protozoa is acceptable.

most common parasites

The most common internal parasite is, of course, helminths, which according to various sources infects more than 80% of the world's population.

These parasites are numerous and can be divided into the following main types:

• Nematodes - roundworms (roundworms, pinworms, trichinella spiralis, whipworms, etc.);
• Tapeworms – Tapeworms (Tapeworm, Pork and Bovine Tapeworm, Echinococcus, etc.);
• Flukes - Flukes (liver flukes, schistosomiasis, lung flukes, and flukes that live in the intestines).

Sometimes you can find a more general classification, according to which all types of human parasites are divided into:

• lumen (intestine), parasitic in the intestine;
• Tissues, located within other organs and tissues.

Let's look at a brief description of the most common types of worms.

Roundworms (nematodes)

• Roundworms are the most common roundworms, measuring 20 to 40 centimeters long. They live in the small intestine but first migrate into the human body, affecting the circulatory and respiratory systems.In addition to the intestines, these parasites can also be found in the liver, gallbladder, heart, and lungs.A common symptom of ascariasis is an allergic reaction.
• Pinworms are small worms up to 1 cm in length that affect the intestines and lead to pinworm disease, which is accompanied by gastrointestinal disorders, fatigue, sleep disorders, and more.A characteristic symptom of the presence of pinworms is itching in the anus, where the pinworms lay their eggs.
• Trichinella spiralis - These tiny worms (their size is only a few millimeters) can cause a serious disease - trichinellosis, which can lead to death if left untreated.Adult species live in the muscles of the human body (respiratory system, face, etc.) and cause muscle pain, fever, swelling, and allergic rashes.
• Whipworms are small worms (up to 4.5 cm long, with the front part of the body

thread-like), whose larvae cause whipworm disease, with diarrhea, acute abdominal pain, and other appendicitis-like symptoms.Anemia occurs due to poisoning of the body.

Tapeworm (Tapeworm)

• The broad tapeworm, which can grow up to 10 m long, can cause dilofilariasis, which is accompanied by nausea, weakness, vomiting, unsteady stools, weakness and anemia.
• The pork tapeworm is 3 to 8 meters long and mainly lives in the small intestine. It can cause two diseases at the same time: tapeworm disease accompanied by indigestion, asthenic neurosis and abdominal syndrome, and cysticercosis accompanied by poisoning, intestinal, allergic and respiratory syndrome.Depending on where the cysticerci are located, the muscles, brain, heart, eyes, etc. can be affected.
• Bovine tapeworms, which can grow up to 18 m in length, cause the disease Thyroides and are considered one of the most dangerous types of worms.If it is not dewormed, it can survive in the human body for up to 18-20 years!It is located in the large intestine and can cause severe waste poisoning, as well as diarrhea, nausea, vomiting, abdominal pain, anemia, allergic reactions and neurological problems.
• The dwarf tapeworm, which is only 1.5-5 centimeters long, is the cause of a membranous dermatosis with indigestion, pain and a neurasthenic syndrome that mainly affects the body's digestive and nervous systems as well as the liver.
• Echinococcus is considered the smallest of the tapeworms - it is only 2.5 to 8 mm in length, and rarely 9 mm, but infection with it can have dire consequences, damaging the liver and lungs, forming cysts and tumors, leading to dysfunction of these organs.

Flukes (trematodes)

• Liver flukes, also known as liver flukes, are leaf-shaped, 30-50 mm long, 8-13 mm wide, and have suckers.It damages the lining of the liver and completely blocks the flow of bile by blocking the bile ducts.May cause cirrhosis, jaundice and liver cancer.
• Cat (Siberian) fluke, or cat fluke, is a flat worm 4-13 mm long.Location - Ducts of the gallbladder, liver and pancreas.It can cause opisthodidymia and progress to gastritis, ulcers, pancreatitis, cholecystitis, and even liver cancer, which can be fatal.
• Paragonimiasis is oval in shape, with a reddish-brown body and small spines. It is 7.5 to 12 mm long and 4 to 8 mm wide.It affects the lungs, causing inflammation, effusion pleurisy, focal fibrosis, and lung cancer.Once it penetrates the brain, it can cause encephalitis and meningoencephalitis.
• Schistosoma is a dioecious worm with a size of 1-2 cm. Its eggs can cause enlargement of the liver, spleen and lymph nodes, form polyps, diarrhea, granulomatous inflammation in the intestine, and lead to bladder cancer.

diseases they cause

The most dangerous parasites that live in the human body can cause a variety of diseases.Often, the disease caused by a specific parasite shares its name.Therefore, various types of parasites in the human body can cause the following diseases:

• Certain parasites (flukes) in the human body cause flukes;
• Taeniasis occurs when a tapeworm infection occurs;
• If an adult or child has roundworms in their intestines, nematodes are diagnosed;
• Leeches cause leech disease;
• Ceratocephalus is caused by acanthus.

However, parasites in humans can affect multiple organs.According to the location of the parasite in the human body, parasitic diseases can be divided into the following:

1. When the eyes are affected, onchocerciasis, demodicosis, cysticercosis, and myiasis may occur;
2. Gastrointestinal diseases caused by single-celled parasites and helminths include ascariasis, trichinellosis, hookworms, pinworms, intestinal myiasis, and metaascariasis;
3. Brain diseases - hydatid disease, toxoplasmosis, alveococcosis and cysticercosis;
4. Skin diseases - demodicosis, pediculosis, scabies, pediculosis, thrombosis, ringworm;
5. Pulmonary lesions - hydatid disease, ascariasis, mite disease, alveolar coccosis, ascariasis, etc.;
6. Liver diseases - opioditis, alveolar coccosis, hydatid disease, clonorchiasis;
7. In the mouth, ears, and oral cavity, parasites can cause different types of myiasis;
8. Cardiac pathology—dilobite and hydatid disease;
9. Urogenital diseases - alveolar coccosis, urate myiasis, hydatid disease;
10. Vascular lesions - filariasis and schistosomiasis.

flatworm

Parasitic flatworms, or flukes (trematodes), have a characteristic leaf-like body shape.They have a very organized structure—they have a digestive system, an excretory system, and a nervous system.They change hosts during their life cycle.

The following types have become common:

1. Siberian flukes (cat flukes), or Opisthorchis flukes.Most often, the infection occurs through raw fish, which leads to the emergence of a rather dangerous disease - opiozoria.Parasites reproduce very quickly and can have serious consequences.The worms are yellowish in color and can exceed 12 m in length.Once these parasites gain a foothold in the body, they can cause internal bleeding, disrupt bile flow, and lead to pancreatic dysfunction.Dangerous consequences: Suppurative cholangitis, abile, cholangiocarcinoma.

2. Liver fluke.The intermediate host is cattle, and humans become infected by eating poorly processed meat from infected animals.Infection leads to the development of fascioliasis.The size of these worms is relatively small (no more than 5-6 cm), but they can cause dangerous pathologies: liver abscess, cholangitis, hepatitis.Through the blood, parasite larvae can spread throughout the body.
3. Schistosomiasis.The worm is able to colonize blood vessels and consume blood components.Due to its important activity, the formation of varicose veins and tumors is possible.The main symptom is severe systemic intoxication.

Within the human body, you can find a large number of different parasites that can inhabit various internal organs.All of these can lead to chronic illness that can lead to serious illness.If signs of any type of helminthiasis develop, you should consult your doctor to begin appropriate treatment.

bull tapeworm

The length of the bovine tapeworm can reach 12 m.It is hermaphrodite and can lay more than 100,000 eggs, which are excreted through feces.The eggs fall into the soil and then onto plants, which are eaten by cattle.Inside the animal, the eggs turn into larvae, which become lodged in the muscles.If a person eats contaminated beef, the larvae can enter the intestines.The larvae are not spread from person to person.

The adult insect has a head with four suckers, a neck, and a body made of segments.The number of segments continues to grow; mature segments can be separated from the worms and crawl out of the human intestine.

bull tapeworm

Symptoms of the disease are nausea, vomiting, indigestion, increased salivation, dizziness, weakness, nervousness, fatigue, abdominal pain of unknown location, allergies, and appetite fluctuations.

To remove bovine tapeworms from the body, there is a program consisting of 3 stages: preparation (cleansing the body), treatment with antiparasitic drugs, recovery (diet, herbs).

tapeworm

Tapeworms, or tapeworms, include a variety of flatworms that range in length from 2 mm to 10-12 m.The body of this parasite has a specific structure - many segments, a neck and a head with suckers (hooks) for attachment to walls.Tapeworms are hermaphrodites and their eggs are laid within the body segments.Worms absorb nutrients through the entire surface of their bodies.

Tapeworms can be divided into the following common types:

1. Ascoccus spp.They can cause cholangitis and abscesses and spread to the spleen, muscles and brain.
2. Tapeworm, or tapeworm.The bovine tapeworm causes thin neck disease, usually in the small intestine.Serious complications - cholecystitis, intestinal obstruction, appendicitis.This worm can cause the following consequences: atrophy of the intestinal wall, Gunther's glossitis, leukopenia.

protozoan parasites

Toxoplasma gondii is a parasite whose primary host is cats.They can also be carried by warm-blooded animals and humans.The disease caused by Toxoplasma gondii is called toxoplasmosis.The course of the disease is mild, but it can cause damage to the fetus in the mother's womb during pregnancy, causing serious consequences to both the mother and the fetus, and even death.

Amoeba is a simple single-celled organism thought to be one of the first organisms to live on Earth.Diseases caused by amoebiasis are called amoebiasis.Intestinal infections, mainly ulcerative lesions of the large intestine, may cause bloody diarrhea, which may form secondary intestinal lesions and tend to be chronic.

Plasmodium is the simplest single-celled organism. During its development cycle, humans are the temporary host and mosquitoes are the permanent host.There are 4 types of parasitic malaria parasites in the human body:

• P. malarie—four days of malaria;
• P.vivax - malaria malaria;
• P.ovale - three-day ovale malaria;
• P.falciparum - tropical malaria;

The duration of the intervals between outbreaks depends on the type of pathogen.In addition, anemia can occur due to malaria parasites affecting red blood cells.

Giardia is a pear-shaped protozoa with two nuclei and four pairs of flagella.The main sources are pigs and humans.Giardiasis is a common disease that primarily affects the liver and small intestine.The disease can have both mild and severe forms.

Trichomonas is a flagellated, unicellular, pear-shaped organism that causes trichomoniasis, which is sexually transmitted and affects the genitourinary system.It is important to note that both men and women are affected, but the disease is usually asymptomatic in men.

Trypanosomatids are unicellular flagellated protozoa.Trypanosomiasis causes severe illness, and sleeping sickness is fatal in humans.Trypanosomes are spread by bed bugs and tsetse flies.Inside the host, the parasite multiplies under the skin and then penetrates the lymphatic system and bloodstream.Most pathogens are located in the spinal cord and brain, where they damage cells and release toxins.
