Types of worms in the human body

Various living beings can live in the human body. We call parasites those that are harmful to human health through their vital activities. Parasites in the human body are not necessarily worms, there may be other living organisms that harm humans. Dangerous parasites can live all over the earth. So what are parasites and how do they affect humans?

Types of Parasites

There are more than 2, 000 types of parasites in the human body. They are divided according to their type, way of life, methods of reproduction. There are also mandatory and optional parasites.

Mandatory parasites can only live in the host's body. Mandatory intracellular parasites are completely dependent on their host and therefore do not seriously harm them.

They are free to live part of their optional life cycle and keep the other part in the body of the host. Each of these can affect various internal organs and tissues. Some of them have existed for a long time, but at the same time they do not manifest in any way. The appearance of others is accompanied by characteristic symptoms.

Helminthiasis

Human helminthiasis is caused by various worms. There are currently more than 300 types of helminths in humans. Worms include, are mandatory parasites and are optional. In addition, depending on the form of the parasite-host interaction, they can be divided into two groups: ectoparasites and endoparasites. They belong to different classes and can parasitize in different organs. Worms in humans are one of the most common diseases; geohelmintus worms are most commonly found. The appearance of worms in humans is not only provoked by dirty hands. It can be infected from pets, livestock, fish, and dirty water. The disease depends on the type of worms that have entered the body. To understand the consequences that worms can cause, you need to find out what the worms are. By knowing what worms can occur and their characteristics, you can protect yourself from infection.

• Roundworms. Most worms in this class are parasitic. The main differences in this class are: duodenal cavity, existing anus, presence of primary body cavity. The most common helminths in humans are roundworms, pinworms, trichinella and whipworms. Roundworms are geohelmed samples, meaning no temporary host is required for maturation and reproduction. All of their vital activities can occur within an organization. Some geohelminths in pets can be dangerous to humans, such as toxocara worms.
• Tapeworms are parasites in the human body that live mainly in the intestines. There are two groups of tapeworms: biohelmam samples and geohelms. Most worms of this species are biohelminths. In order for them to develop, they need to enter the organization of an intermediate farmer, which includes livestock as well as fish and molluscs. The most common tapeworms in this group include bovine tapeworm, broad tapeworm, echinococcus, alveococcus. Tapeworms can grow large, parasitize the human body. The longest worm - the broad tapeworm can reach 25 meters in length.
• Suckers. One of the most complex organisms that can live in a person. All of these parasites can infect various organs. Any worm of this type can cause trematodes. Fluke, liver fluke, lanceolate fluke, fluke flukes.
• Scrapers or spiny-headed worms are among the smallest tapeworms. These types of parasites are quite rare in the human body. You can get them from sick fish. They only parasitize in the intestines as they have no digestive system. There are also representatives in the human body like giant scrapers.

Protists

Protists are the simplest organisms. They belong to a heterogeneous group of living organisms. Protists cannot be classified as animals or fungi. Protists are unicellular, colonial, and less commonly multicellular. Some of them can parasitize the human body. The most dangerous protists are malaria plasmodium and dysentery amoeba. Parasites can cause diseases such as malaria, dysentery and dysentery. Different types cause severe pathologies in humans. And if they are identified, you should see a doctor.

Entomosis

Various insects, especially those in tropical countries, cause entomosis. Entomosis causes various pathological changes in human organs. The eyes, skin and gastrointestinal tract are most commonly affected. Various insects can cause entomosis:

• Mosquitoes, fleas, and bugs - infect unprotected areas of human skin.
• Gadgets and flies - infect humans, laying off their offspring in the form of eggs or larvae on the skin wound. Certain types of flies can also become infected by swallowing their larvae.

Any insect that parasitizes the human body is capable of releasing toxic substances. Depending on the pathogen, the clinical picture is displayed. Insects can have allergic and mechanical effects on humans.

TOP - 7 most common parasites

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

1. Filaria.A thin long worm found in tropical and subtropical zones. The parasite is carried by mosquitoes. Filariae causes a terrible disease like elephantiasis. In the countries where the parasite is found, more than one hundred and twenty million people suffer from elephantiasis. Filariae, which parasitizes the body, clogs the lymphatics. After that, the person begins to grow strongly in the limbs.
2. Anisakids.Anisakid larvae have long been considered harmless. But the XX. In the middle of the century, scientists discovered that anisakidosis disease can even lead to death in some cases. It can become infected with parasites from poorly heat-treated seafood, including fish. Anisakids are one of the most horrible parasites in humans. Anisakid larvae that enter the stomach provoke the development of tumors and ulcers.
3. One of the most famous parasites is thebovine tapeworm.It has been infected with a worm through dirty hands or raw meat, so one cannot know about the disease for a long time. Geohelmed samples of this species cause severe weight loss. Its size can reach several meters inside the owner. Sometimes they live in the body for many years, they do not manifest at all.
4. Schistosome.With the development of tourism, these types of parasites began to expand their geography. Living in tropical wild forests, schistosome can enter the body by swimming in parasitic water bodies. May cause severe liver and bladder disease. Particularly dangerous for children. In a child’s body, a schistosome provokes the development of anemia and is able to stop growth.
5. Risht.Lives in subtropical regions of Asia and Africa. Guinea pig dracunculiasis is a dangerous disease. The female Rishta breaks through the skin of the host during the laying of the larvae. The person feels severe pain and itching. If you drink dirty water, there is a high risk of getting dracunculiasis.
6. Parasites primarily affect the digestive system, liver and skin. But there are species that live in the brain, such ascysticercus.They can live for up to 30 years, causing mental disorders: hallucinations, depression, short-term memory loss.
7. Toxoplasma.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 uterus. It most often causes severe pathologies and leads to fetal death. The acquired disease affects the central nervous system and can cause brain cancer. Toxoplasma often causes the development of schizophrenia.
