Types of worms in the human body

Various organisms can inhabit the human body. Those which, by their essential activity, endanger human health, are called parasites. Parasites in the human body are not necessarily worms, they can also be other living organisms that cause damage to humans. Harmful parasites can inhabit the entire territory of the earth. So what is a parasite and how does it affect humans?

Types of parasites

There are more than 2000 representative types of parasites in the human body. They are divided according to type, way of life, method of reproduction. There are also mandatory and facultative parasites.

Mandatory parasites can only live in the host body. Intracellular parasites are obliged to depend entirely on their host, so that they do not seriously harm them.

Choices can undergo part of their life cycle as independent living, other parts can be held in the host body. All of them can affect various internal organs and tissues. Some of them 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, there are more than 300 types of helminths in humans. There are among the worms, both in need of parasites and selection. Also, 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 perform parasites in various organs. Worms in humans are one of the most common diseases; geohelminth worms are most commonly found. The appearance of worms in humans can be provoked, not just by dirty hands. You can be infected from pets, livestock, fish, and even dirty water. The disease depends on the type of worm that enters the body. To understand what consequences a worm can cause, you need to know what a worm is. By knowing what worms can happen and their characteristics, you can protect yourself from infection.

• Ringworm. A large number of worms in this class are parasites. The main differences of this class are: dioecious cavities, available anus, the presence of primary body cavities. The most common types of helminths in humans are ringworm, cream worms, trichinella, whip. Ringworms are geohelminths, i. e. temporary hosts not needed for their maturation and reproduction. All their important activities can take place in one organism. Some geohelminths in pets can be dangerous to humans, for example, toxocara worms.
• Tapeworms are parasites in the human body that live mainly in the intestines. There are two groups of tapeworms: biohelminths and geohelminths. A large number of worms of this species are biohelminths. For its development, they need to enter the body of the intermediary host, namely livestock, as well as fish and mollusks. The most common tapeworms in this group include bovine tapeworms, broad tapeworms, echinococcus, alveococcus. Tapeworms can grow to large size, parasites on the human body. The longest worm - a wide tapeworm can reach a length of 25 meters.
• Suckers. One of the most complex organisms that can live in a person. All these parasites can infect various organs. Any type of worm of this type causes trematodes. Fluke, heart fluke, fluke flance, is a fluke flux.
• Scraper or barbed -headed worms are among the smallest tapeworms. This type of parasite is relatively rare in the human body. You can get it from a sick fish. They are parasites only in the intestines, because they have no digestive system. Also in the human body there is a representation like a giant scraper.

Protista

Protista is the simplest organism. They belong to a heterogeneous group of living organisms. Protists cannot be classified as animals or fungi. Protists are unicellular, colonial, and rarely multicellular organisms. Some of them can do parasites in the human body. The most dangerous protists are plasmodium malaria and amphibious amoebae. Parasites can cause diseases such as malaria, dysentery. Various types cause severe pathology in humans. If they are identified, you must see a doctor.

Entomosis

Various insects, especially those living in tropical countries, cause entomosis. Entomosis causes a variety of pathological changes in human organs. Often, the eye, skin, and gastrointestinal tract systems are affected. Various insects can cause entomosis:

• Mosquitoes, lice and fleas - infect through unprotected areas of human skin.
• flies and flies - infect humans, laying their offspring in the form of eggs or larvae on skin wounds. You can also be infected from some types of flies by swallowing their larvae.

All insects that parasitize the human body have the ability to release toxic substances. Depending on the pathogen, a clinical picture emerges. Insects can have allergic and mechanical effects on humans.

TOP - 7 most common parasites

Parasites that live in the human body can cause serious diseases. We offer 7 of the most creepy and horrible parasitic parasites that can inhabit the human body. From the list, you can find out which parasites live in different countries and how dangerous they are.

1. Filaria.Thin long worms found in tropical and subtropical zones. The parasite is carried by mosquitoes. Filariae cause terrible diseases such as elephantiasis. In countries where parasites are found, more than one hundred and twenty million people suffer from elephantiasis. Filariae, parasites in the body, clog the lymphatic vessels. After that, the person begins strong limb growth.
2. Anisakid.Anisakid larvae have long been considered harmless. But in the middle of the XX century, scientists discovered that the disease anisacidosis can lead in some cases to death. You can be infected with parasites from poorly processed seafood, including fish. Anisakid is one of the most devastating parasites on humans. Anisakid larvae enter the stomach provoking tumor formation and the development of abscesses.
3. One of the most famous parasites is the tapeworm.After being infected with worms through dirty hands or raw meat, a person may not have known about the disease for a long time. Geohelminth of this species causes severe weight loss. By its size, being inside its owner, it can reach several meters. Sometimes they live in the body for years, not manifesting at all.
4. Schistosoma.With the development of tourism, this type of parasite began to expand its geography. Living in tropical wild forests, schistosome parasites can enter the body while swimming in bodies of water. It can cause serious liver and bladder disease. Especially dangerous for children. In a child's body, schistosomes provoke the development of anemia and are able to stop growth.
5. Risht.Inhabits subtropics in Asia and Africa. Dracunculiasis, which causes guinea worms, is a dangerous disease. While laying the larva by the female Rishta, it penetrates the skin of the host. The person felt severe pain and itching. There is a great risk of contracting dracunculiasis when drinking dirty water.
6. Parasites mainly affect the digestive tract, liver and skin. But there are species that live in the brain, such ascysticercus.They can live up to 30 years, causing mental disorders: hallucinations, depression, short -term memory loss.
7. Toxoplasma.One of the most common helminths on earth. Toxoplasmosis consists of two types: congenital and acquired. In the first case, the infection occurs in the uterus. Often it causes serious pathology and leads to fetal death. Acquired diseases affect the central nervous system and can lead to brain cancer. Toxoplasma often leads to the development of schizophrenia.
