Types of worms in the human body

Different organisms can live in the human body. Those who harm human health with their vital activities are called parasites. Parasites in the human body are not necessarily worms, but can be other living organisms that harm humans. Dangerous parasites can live all over the world. What are parasites, and how do they affect humans?

Types of parasites

There are more than 2, 000 species of parasites in the human body. They are divided by species, mode of existence, methods of reproduction. There are also mandatory and optional parasites.

Forced parasites can only live in the host's body. Debt intracellular parasites are completely dependent on the host, so they do not cause serious harm.

Voluntarily, part of the life cycle can be lived freely, and the other part can be kept in the body of the host. All of them can affect different internal organs and tissues. Some exist for a long time and at the same time do not manifest themselves in any way. The appearance of others is accompanied by characteristic symptoms.

Helminthiasis

Human helminthiasis is caused by various worms. Currently, humans have more than 300 species of helminths. Both compulsive parasites and, optionally, worms have been found. In addition, depending on the form of interaction of the parasite with the host organism, they are divided into two groups: ectoparasites and endoparasites. They belong to different classes and can be parasitized in different organs. Worms in humans are one of the most common diseases; geohelminth worms are the most common. The appearance of worms in humans can be provoked not only by dirty hands. You can be infected by pets, livestock, fish, as well as contaminated water. The disease depends on what kind of worms enter the body. To understand what consequences worms can cause, you need to learn what worms are. You can protect yourself from infection by knowing which worms can form and their characteristics.

• Round Worms. Most worms in this class are parasites. The main differences of this class are: the presence of a two-part cavity, the existing anus, the primary body cavity. The most common types of helminths in humans are roundworms, pinworms, trichinella, whipworms. Roundworms are geohelminths, meaning they do not require a temporary host to grow and reproduce. All vital activities can take place within an organism. Some geohelminths in pets can be dangerous to humans, such as toxocara worms.
• Tapeworms are parasites that live in the human body, mainly in the intestines. Two ribbons formed ribbons: biohelminths and geohelminths. Most worms of this species are biohelminths. For their development, they need to enter the body of an intermediate host, ie livestock, as well as fish and mollusks. The most common worms in this group are cattle tapeworm, tapeworm, echinococcus, alveococcus. Tapeworms can grow to a large extent by parasitizing the human body. The longest worm - a broad-leaved worm can reach a length of 25 meters.
• Absorbents. It is one of the most complex organisms that can live in a human being. All of these parasites can infect various organs. Every type of worm of this type causes trematodes. Fluke, liver fluke, lanceolate fluke, fluke flukes.
• Climbers or thorny worms are among the smallest tapeworms. This type of parasite is very rare in the human body. You can get them from sick fish. Because they do not have a digestive system, they only parasitize in the intestines. There are representatives in the human body like giant scrapers.

Protists

Protists are the simplest organisms. They belong to a group of heterogeneous living organisms. Protestants cannot be classified as animals or mushrooms. Protists are unicellular, colonial, and less common multicellular organisms. Some can be parasitized on the human body. The most dangerous protists are malaria plasmodium and dysentery amoeba. Parasites can cause diseases such as malaria and dysentery. Different types cause serious pathologies in humans. And when it is diagnosed, you should consult a doctor.

Entomosis

Various insects, especially those living in tropical countries, cause entomosis. Entomosis causes various pathological changes in human organs. Often affects the eyes, skin and gastrointestinal tract. Various insects can cause entomosis:

• Mosquitoes, fleas and insects infect unprotected areas of human skin.
• gadflies and flies - infect humans, leaving their offspring in skin lesions in the form of eggs or larvae. You can also be infected by some types of flies by swallowing larvae.

All insects that parasitize the human body have the ability to secrete toxins. The clinical picture of the pathogen is visible. Insects can cause allergic and mechanical effects in humans.

TOP - 7 most common parasites

Parasites living in the human body can cause serious diseases. We offer the first seven of the most creepy and terrible parasites that can live in the human body. From the list you can learn what parasites live in different countries and how dangerous they are.

1. Filaria.A thin, long worm in the tropics and subtropics. The parasite is carried by mosquitoes. Philaria causes a terrible disease like elephantiasis. In countries where the parasite is present, more than one hundred and twenty million people suffer from elephantiasis. The parasitic filariasis closes the lymphatic vessels in the body. After that, the human limbs begin to grow strongly.
2. Anisakids.Anisakid larvae have long been considered harmless. However, in the middle of the twentieth century, scientists discovered that anisakidosis could sometimes be fatal. You can get parasites from poorly processed seafood, including fish. Anisakids are one of the most terrifying parasites in humans. Anisakid larvae that enter the stomach stimulate the formation of tumors and the development of ulcers.
3. One of the most popular parasites is thebovine tapeworm.A person infected with a worm from dirty hands or raw meat does not know about the disease for a long time. Geohelminths of this species cause severe weight loss. It can reach several meters in size when inside the owner. Sometimes they live in their bodies for many years and do not show themselves at all.
4. Schistosoma.With the development of tourism, this type of parasite began to expand its geography. The schistosome parasite, which lives in tropical wild forests, can enter the body while bathing in water bodies. May cause severe liver and bladder disease. It is especially dangerous for children. In a child's body, schistosomiasis causes the development of anemia and can stop growth.
5. Risht.Lives in the subtropics of Asia and Africa. Dracunculitis, which causes guinea pigs, is a dangerous disease. The female breaks the host's skin during the laying of the larvae by Rishta. The person feels severe pain and itching. The risk of infection with dracunculiasis is high when drinking contaminated water.
6. Parasites mainly affect the digestive system, liver and skin. However, there are species living in the brain, such as the cysticercus.Can live up to 30 years, causing mental disorders: hallucinations, depression, short-term memory loss.
7. Toxoplasma.It is one of the most common helminths on Earth. There are two types of toxoplasmosis: congenital and acquired. In the first case, the infection occurs in the womb. It often leads to serious pathologies and fetal death. Acquired disease affects the central nervous system and can lead to brain cancer. Toxoplasma often causes the development of schizophrenia.
