Types of worms in the human body

Many different creatures can live in the human body. Species that, due to their vital activity harmful to human health, are called parasites. Parasites in the human body do not have to be worms, they can also be other living organisms that harm humans. Dangerous parasites can inhabit the entire territory of the earth. So what are parasites and how do they affect people?

Types of parasites

There are more than 2000 representatives of all types of parasites in the human body. They are divided according to type, mode of existence, mode of reproduction. There are also obligatory and easy to parasite.

The parasite can only live in the host's body. Required intracellular parasites are completely dependent on their host, so they do not cause serious harm to him.

Optionally be able to live part of their life cycle as free life, the rest can be kept in the host's body. All of them can affect various internal organs and tissues. Some of them last for a long time and at the same time do not manifest in any way. The appearance of others is accompanied by characteristic symptoms.

Threadworm disease

Torniasis in humans is caused by many different types of worms. Currently, there are more than 300 types of human helminths. Found among the worms, both mandatory and non-mandatory parasites. In addition, depending on the form of the parasite's interaction with the host organism, they are divided into two groups: exogenous and endogenous. They belong to different classes and can parasitize in many different organs. Worms in humans are one of the most common, with helminths most commonly found. The appearance of worms in humans can be provoked, not just with dirty hands. You can get sick from pets, livestock, and fish, as well as dirty water. The disease depends on the types of worms that have entered the body. To understand the consequences that worms can have, you need to understand what worms are. Knowing what worms are likely to happen and their characteristics, you can protect yourself from infection.

• Nematodes. Most of the worms in this class are parasitic. The main difference of this class is: a single-celled cavity, an existing anus, the presence of a main body cavity. Common types of helminths in humans are roundworms, pinworms, helminths, whipworms. Nematodes are earthworms, meaning they don't need a temporary host for them to mature and reproduce. All of their vital activities can take place inside an organism. Certain cysticercosis in domestic animals can become dangerous to humans, for example, Toxocariasis.
• Tapeworms are parasites in the human body that mainly live in the intestines. There are two groups of tapeworms: biological helminths and geographic helminths. The majority of worms of this species are helminths. To grow, they need to enter the body of an intermediate host, pets, as well as fish and mollusks. The most common tapeworms in this group include the bovine tapeworm, the broad tapeworm, echinococcus, and alveococcus. Tapeworms can develop with a large size, parasitic on the human body. The longest worm - the wide tapeworm that can grow up to 25 meters long.
• Idiot. One of the most complex creatures that can live in humans. All of these parasites can infect different organs. Any type of worms of this type cause trematodes. Small liver fluke, a liver fluke, are small liver fluke.
• Scratchworms or dendritic worms are one of 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 gut, because they don't have a digestive system. In addition, in the human body there are representatives like giant curettles.

Protozoa

Protozoa are the simplest creatures. They belong to a heterogeneous group of living organisms. Protozoa cannot be classified as animals or fungi. Protozoa are single-celled, colonial and less common organisms that are multicellular. Some of them can be parasitic in the human body. The most dangerous protozoa are plasmodium malaria and amoebic dysentery. The parasite can cause diseases such as malaria, dysentery. Many different types cause serious illnesses in humans. And if they are identified, you must consult a doctor.

Entomosis

Many different types of insects, especially those that live in tropical countries, cause insect disease. Entomosis causes various pathological changes in human organs. Most often, the eyes, skin and digestive system are affected. Several types of insects can cause insect disease:

• Mosquitoes, fleas and bugs - infect unprotected areas of human skin.
• gadfly and flies - infect humans, lay their offspring in the form of eggs or larvae on a wound in the skin. You can also become infected with certain types of flies by swallowing their larvae.

All parasitic insects on the human body have the ability to release toxic substances. Depending on the pathogen, the clinical picture appears. Insects can have an allergic and mechanical effect on humans.

TOP - The 7 most common types of parasites

The parasites that live in the human body can cause dangerous diseases. We would like to present the top 7 most terrifying and terrible parasites that can live on the human body. From the list you can find out which parasites live in different countries and how dangerous they are.

1. Filaria.A species of long thin worm found in tropical and subtropical regions. The parasite is carried by mosquitoes. Filariae caused a terrible illness like the edema of the elephant's foot. In the countries where the parasite is found, more than one hundred and twenty million inhabitants suffer from elephantiasis. Filariae, a parasite in the body, clogged the lymphatic vessels. Then, the person begins to thrive limbs.
2. Anisakids.Anisakid larvae have long been considered harmless. But in the mid-twentieth century, scientists discovered that anisakidosis can lead to death in some cases. You can get parasites from poorly processed seafood, including fish. Anisakids are one of the most terrible types of parasites in humans. Anisakid larvae enter the stomach causing the formation of tumors and the development of ulcers.
3. One of the most famous parasites is the bovine tapeworm.Infected with the worm through dirty hands or raw meat, a person may not be aware of the disease for a long time. The larvae of this species cause severe weight loss. Given its size, inside the owner, it can reach several meters. Sometimes they live in the body for many years, not showing out.
4. Schistosoma.With the development of tourism, this parasite began to expand geographically. Living in tropical wilderness, schistosome can enter the body while swimming in water bodies. It can cause serious bladder and liver disease. Especially dangerous for children. In the child's body, the allergic form stimulates the development of anemia and may stop growth.
5. Risht.Lives in subtropical regions of Asia and Africa. Dracunculiasis, which causes guinea worms, is a dangerous disease. During the spawning of female Rishta larvae, it penetrates the skin of the host. The patient feels severe pain and itching. There is a high risk of getting dracunculiasis when drinking dirty water.
6. The parasite mainly affects 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 is of two types: congenital and acquired. In the first case, the infection occurs in the uterus. Usually it causes serious illness and death of the fetus. The acquired disease affects the central nervous system and can cause brain cancer. Toxoplasma often causes the development of schizophrenia.
