The human body is constantly exposed to dangers from the outside. This is a different type of disease, infection and so on. One of the most common, serious problems is parasites. They enter the body completely unnoticed, the consequences can be very serious. It is important to know which parasites in the human body are the most dangerous, what are the health threats due to them. You can see the parasites in detail in the photo.

Different worms live all over the world, all are divided according to the mode of transmission, type. Parasitic worms are transmitted to humans mainly in the following ways:

What to do in such a situation? To get started, we recommend reading this article. This article details the methods of dealing with parasites. We also recommend contacting a specialist. Read the article >>>

  • an infected person;
  • animals;
  • soil, food, water;
  • insect bites.

Worms are divided into several types:

  • flukes;
  • round;
  • tape.

Worms are a very large class of parasitic worms that live in the body of plants, animals, humans. They can live in hollow organs, thicker tissues, the tissues themselves.

Top 10 most dangerous parasites in the human body

  • Schistosomes are dangerous parasites from tropical waters.
  • Rishta is a worm that lives under the human skin.
  • Filariae are dangerous parasites of elephant disease.
  • Echinococcus is a dangerous larva in the body.
  • The whiskered Vandellia is a fish parasite.
  • Roundworms are known to all worms.
  • Bovine tapeworm is a very large and long worm.
  • Hookworm is a small harmful worm.
  • Wide tapeworm is a danger to the human intestine.
  • Pork tapeworm is a dangerous disease.

Round worms

This type of worms are also called nematodes, and many of their representatives parasitize in humans and other animals. They can be localized in all organs and tissues, but most affect the digestive tract.

Human Ascaris / Ascaris lumbricoides

The largest worms in the human body, growing up to 40 cm. The parasitic roundworm lives in the small intestine, and can cause a dangerous disease ascariasis.

It does not attach in the body, but constantly moves towards the food masses. Of all the sense organs in roundworms, only the tactile hillocks are developed. These papillomas are located near the mouth.

Large white worms do not change their host during their life cycle and, in addition to the intestines, can infect other human organs. Ascaris eggs enter the body with unwashed fruits, vegetables, and they can also be transferred to the food of flies.

One of the most famous representatives of this type is earthworms. They live on all continents except Antarctica, and the largest earthworms are found on the "Green Continent".

Megascolides australis

The Australian giant earthworm was discovered and described in 1878 by British paleontologist Frederick McCoy in Victoria.

Adults reach 80 cm in length and 3 cm in diameter. Some species reach 3 m, but it is rather difficult to find such specimens. They are found only in a small region of the Bass River valley in the south of Gippsland. Like most worms, they are hermaphrodites. Puberty occurs in the fifth year of life.

Megascolides australis feed on plant roots and detritus. Under the ground, such giants build complex systems of passages, where they spend their entire lives. It belongs to an endangered species. This species, albeit gigantic, cannot always adapt to changes in the environment, and often dies.

Large underground worms are found on other continents. According to unconfirmed reports, worms over 3 meters long are found in the vastness of New Zealand. Plus, they glow in the dark.

In 1967, the largest earthworm was discovered in southern Africa, the length of which was 6.5 m. Favorable weather conditions contribute to the growth of worms. Large individuals were found in China, in the Sipun province. Chinese specimens reached 1.5 m in length.

Individuals up to half a meter in length were also found in Russia. Long worms were found in the North Caucasus and the Urals. Russians usually use smaller representatives for fishing.


Tapeworms belong to a large class of flatworms that parasitize the body of vertebrates. The body of tapeworms consists of a large number of metameres, separate segments of the same structure. To date, more than 3,500 species of such living organisms have been described.

Broad Tapeworm / Diphyllobothrium latum

Usually flatworms live in the seas and oceans, but some species parasitize various animals.

The broad tapeworm is the largest of all flatworms, growing up to 25 cm in length. Some individuals, under favorable conditions, can grow up to 1 m. The adult stage of the life cycle takes place in the intestines of humans, as well as animals in the diet of fish. It enters the body when eating contaminated, non-thermally processed fish.

Eggs develop in water bodies, and then small white worms develop in fish. The head is small, 3 to 5 mm. The head part, which scientists call the scolex, has an oblong oval shape, slightly flattened on both sides.

Bovine tapeworm / Taenia saginata

A large parasitic worm from the Teniida family affects cattle, as well as humans. Once in the human body, such a tapeworm can cause teniarinchiasis, which affects the gastrointestinal tract.

The long articulated body consists of about 2.5 to 5 thousand segments, and the animal itself grows up to 10 m. The body diameter is 17–30 mm. If you do not take treatment, then bovine tapeworm can live in the human body for up to 20 years. He has no organs of nutrition and respiration, and therefore absorbs the necessary nutrients with his whole body.

The intermediate link is cattle, and the main life cycle takes place only in the human body. Most infections were noted in Africa, Eastern Europe, the Philippines and parts of South America.

By the way, on our website there is an informative article about the longest-living animals on the planet.

Pork tapeworm / Taenia solium

Unlike bovine, this parasite has adaptations for attachment in the body, and therefore it is called an armed tapeworm. The larva develops in the body of a pig, and a person acts as the main host of the pork tapeworm.

The adult tapeworm reaches 2–3 m. In the head part, in addition to the suckers, there are two hook-shaped processes with which it attaches to the intestinal walls in humans. It enters the body when eating contaminated pig meat, and therefore requires strict sanitary control over the animals. Sometimes, due to infection, a large number of sick pigs had to be destroyed.

This parasite can use hares, camels, and dogs as intermediate hosts. The fact is that when they dry, the eggs burst, and from the external environment they can easily enter the animal's body.

Lineus longissimus

The tapeworm of the Nemertin species is the longest worm on the planet, because it can grow up to 60 m.This is twice the length of the Blue Whale, which makes Lineus longissimum the longest animal in the world. Indeed, The Biggest!

They live in the ocean off the coast of northwestern Europe, as well as along the coast of Norway, swimming deep into the North and Baltic seas. Despite its long size, the body diameter does not exceed 7–10 mm. Sea giants are predators, but do not hesitate to feed on carrion from the bottom of the ocean.

Adults have red-brown, less often black body color. It was first discovered in 1770, and was added to the scientific classification in 1806. The species was attributed to the genus Lineus, which today has 15 species.

We agree that worms are not the representatives of the animal world that you want to caress. But these amazing creatures are interesting objects for scientific research. Some species of this huge class of the animal kingdom are useful for human life, and in Australia they even erected a monument to an earthworm.

The slither io game is also widespread in the world, in which, while controlling a worm, you need to eat balls without crashing into other worms. There, worms can be very large.

Unconfirmed facts

In the media, there are references to cases when tapeworms were found in a person, reaching a length of 25 and even 33 meters. But these data have not been officially confirmed in any way, so their reliability can be doubted.

The most interesting thing is that giant worms mature quite late, by animal standards. This period occurs only in the fifth year of their life. And after another year they have the ability to lay eggs (it is worth noting that worms are hermaphrodites). Another year later, larvae appear from the eggs. Their length is also quite impressive - about twenty centimeters.

What is the purpose of worms? For the first time, Charles Darwin himself told the world about them. So, these animals contribute to the moisture, mixing and aeration of the earth. They move in the soil, pushing it apart, or swallowing the soil and letting it pass through their body. Boneless people prefer a wet kidney, because in a dry one their activity is significantly inhibited, and sometimes even stops altogether.

Australians are very happy with the neighborhood with such a giant animal. And this even despite the fact that during its journey underground, the worm emits a kind of snort, clearly audible to people on the surface. But this is nothing compared to how much soil the animal cultivates, making holes for itself.

However, mutants were also found in China. True, their dimensions were not so impressive. In Xipun province, a local resident named Li Wong discovered an animal about half a meter long. The worm was in a half-dead state and the finder thought it was a snake. However, upon closer examination, it became clear that this is an ordinary earthworm.

The one that most fishermen in Russia use as live bait. By the way, as experts said after the discovery, favorable climatic conditions, as well as the level of radiation and the amount of harmful chemicals in the soil, contribute to the high growth of worms. Recorders were also found in Russia, cases were recorded in the Urals and the Caucasus.

Longer than a blue whale

It turns out that the longest animal in the world is the tapeworm Lineus longissimus. It can grow up to sixty meters. It turns out that individuals are twice the length of a blue whale and a third of a hairy jellyfish. The tapeworm belongs to the nemertean group of worms, which means "sea nymph".

The body of a tapeworm is made up of muscles. They pump blood because the animal has no heart. Individuals are considered the most primitive organisms, and at the same time dangerous and voracious predators. In order to catch its prey, the animal shoots out a long tube with poisonous sticky hooks.

The longest of the worms is a representative of nemerteans - lineus longissimum. It lives in the seas in the Northwest Atlantic. In 1864, after a storm, one specimen 55 meters long and one centimeter in diameter was thrown onto the coast of Scotland.

However, the longest worm can be such a length that a person cannot even imagine. The Lenius worm lives in deep seclusion, and in the literal sense of the word, at the very bottom of the Atlantic Ocean. They are benthic and curl up their bodies. Perhaps in order to safely leave your entire body in sight, as well as not to lose control over your elongated body. Lineuses are unusually long and thin. They can grow up to 20-30 meters.
