How do worms look in a person (photo). Types of Worms

Worms, which, parasitizing, develop and live in the body of plants, animals and humans, are usually called helminths in medicine, but among the people they are just worms. Diseases caused by them are common anywhere in the world.

Species of parasites

what worms look like in humans

According to statistics, more than a billion people are invaded by helminths, which contribute to the overload of the immune system and make holes in the vessels. You can get rid of these parasites with the help of medication or alternative treatment. Three types of helminths can cause the greatest harm to the human body: flukes, roundworms, and tapeworms. Before choosing a method of deliverance, it is necessary to understand how worms look in a person.

Roundworms

In medical practice, such parasites are called nematodes. This is a very common genus of worms, which has more than twenty-four thousand species, both free-living and parasitic.

The type was given a name with a round shape, which can be seen on a cross section. These are worms with a thin elongated body that is pointed at both ends. The most common representatives of this type, which are parasitic in the human body, are trichina, human roundworm , whipworm, pinworm children. Here it is necessary to find out what worms look like in humans.

The body of roundworm can reach forty centimeters, while males are much smaller than females. Her body is tensed like a string. It is located in the small intestine. This parasite poisons the body with toxins resulting from metabolism.

Pinworms can parasitize in the small and large intestines. This is a small worm, whose body length does not exceed one centimeter. Females usually lay their eggs near the anus, which causes itching. This type of worms can often be found in children.

But the most dangerous types of roundworms for humans are whipworm and trichina.

Flukes

In medical practice, they are called trematodes. This kind of worms in humans (photo - in the article) has a flattened, flat body in the form of a leaf or tongue. The dimensions of these worms can reach one and a half meters. In the human body, these parasites usually get when eating unfried or raw fish or crayfish. Usually parasitize in various, even the most unexpected organs (conjunctival sac or Eustachian tube) or stick to the walls of the excretory ducts.

They do this with the help of suction cups (two or many, depending on the type). In these worms, the digestive, reproductive, and nervous systems are well developed and the respiratory and circulatory systems are practically absent. They feed on the blood of the owner, the contents of his intestines, epithelium or mucus. This is what worms look like in humans.

The name for these helminths was given inaccurate, since they do not suck anything out of the body. But, despite this, the harm done by them is enormous. The intermediate host of such worms are mollusks, then fish, and the final - vertebrates, including humans.

Tape worms in humans

Just like the flukes described above, these are flatworms, subdivided into tapeworms and lentensi. Unlike round ones, these have an intermediate host (animals and fish). It is in his body that larvae develop. Being in a mature state, they usually live in the intestines of the vertebral.

The body of such helminths is divided into segments. The head is the organ of attachment, and then there is a growth zone, so the parasite feeds on the surface of the body, and food for it becomes the host's digested food. From the digestion in the human body of such a worm (as well as many other types of parasites), the antikinase substance secreted by it, which neutralizes pancreatic juice, saves. But in the diagnostic plan for identifying parasites, the most important differences between tapeworms and lentes.

what are human worms

The latter is characterized by a head (scolex), which has two suction grooves or pits at the front end of the helminth. Eggs are secreted into the environment due to the fact that the uterus has its own opening. In the study of feces, they can be detected.

Due to their appearance, they are called tapeworms. A ribbon-like body divided into segments is their characteristic feature. The length of this worm can reach eighteen meters.

With the help of four suction cups located on the head, it is attached to the walls of the intestine. And behind it there is a neck, with the growth of which segments form. It is very difficult to detect the eggs of these parasites because the uterus does not have an outlet. This is what worms look like in humans.

Determination of parasite damage

These worms are characterized by three stages of development. First there is an egg, from which subsequently a larva appears in the intestine, which then migrates to the place of constant habitat (various organs). After this, helminths develop in adults. But some representatives of these worms remain in the same place where they were transformed, that is, in the intestine.

In order to understand where parasites appeared in the body, you need to know what kind of worms a person has. They are divided into contact, that is, transmitted from person to person, geohelminthoses - those that enter the body with the earth on poorly washed plants, biohelminthoses - that enter through the meat of affected animals or fish.

Signs of the presence of parasites in the human body

Typically, signs of damage depend on the developmental stage of the worms themselves. This ailment has an acute and acquired stage. The first can last up to three weeks and is characterized by an allergic rash, asphyxiating dry cough, and an increased level of eosinophils in the blood.

The next stage can last up to several years. Here, the location of parasites, their nutritional characteristics and abundance affect the identification of symptoms. Being fixed on the tissues of distribution sites, worms in humans (photo - in the article) destroy them, causing an inflammatory reaction. And some fast-growing species can cause irreparable harm to health and lead to disruption of vital organs.

Diagnosis of the presence of parasites is made by identifying eggs and larvae using feces, sputum, etc.
