What do worms look like in a person (photo). Types of worms

Worms that parasitize, develop and live in the body of plants, animals and humans, usually in medicine are called "helminths", and in the people it's just worms. Diseases caused by them are common anywhere in the world.

Types of parasites

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 medicamental or folk treatment. The greatest harm to the human body can cause three types of helminths: flukes, round and tapeworms. Before choosing a method of disposal, you need to understand how the worms look like in humans.

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 of both free-living and parasitic.

The name was given a round shape, which can be seen on the cross-section. These are worms with a thin elongated length and pointed at both ends of the body. The most common representatives of this type, which are parasitic in the human body, are Trichina, Ascaridae, Vlasoglavus, Pinacea nursery. Here it is necessary to find out what the worms look like in humans.

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

In the thin and thick part of the intestine, the pinworm can parasitize. It is a small worm, whose body length does not exceed one centimeter. Female usually lays eggs near the anus, which causes itching. This type of worms can often be found in children.

But the most dangerous species of roundworms for humans are vladogo and trichina.

Flukes

In medical practice, they are called trematodes. This kind of worms in man (photo - in the article) has a flattened, flat body in the form of a leaf or tongue. The size of these worms can reach one and a half meters. In the human body, these parasites usually fall into the use of underfed or raw fish or crawfish. Usually parasitize in various, even the most unexpected organs (conjunctival sac or Eustachian tube) or suck in to the walls of the excretory ducts.

They do this with suction cups (two or a lot, depending on the type). These worms are well developed digestive, sexual, nervous systems and are practically absent respiratory and circulatory. They feed on the blood of the host, the contents of his intestines, epithelium or mucus. This is how the worms look like in humans.

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

Tape worms in humans

As well as the above-described flukes, these are flat worms, divided into chained and ribbons. Unlike round, these have an intermediate host (animals and fish). It is in his body that larvae develop. Being in a sexually mature state, they usually live in the intestine of the vertebral body.

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 the food for it becomes the food overcooked by the host. From the digestion in the human body of such a worm (as well as many other kinds of parasites), it saves the substance of antikinase that neutralizes it, neutralizing pancreatic juice. But in the diagnostic plan, when distinguishing parasites, the most important differences are between the chains and the Librarians.

The latter is characterized by a head (scolex) having two suction grooves or pits at the anterior end of the helminth. Eggs are excreted into the external environment due to the fact that the uterus has its own opening. When studying feces, they can be found.

Because of the appearance of the name of the chain. The ribbon-like body, divided into segments, is their characteristic feature. The length of this worm can reach eighteen meters.

With the help of four suckers located on the head, it is attached to the walls of the intestine. And behind it is a cervix, with the growth of which segments are formed. It is very difficult to detect the eggs of these parasites because the uterus does not have a hole. This is how the worms look like in humans.

Definition of lesions by parasites

These worms are characterized by three stages of development. First there is an egg, from which a larva subsequently appears in the intestine, migrating to the place of permanent habitation (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 intestines.

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

Signs of the presence of parasites in the human body

Usually signs of defeat depend on the stage of development 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, suffocating a dry cough, and in the blood there is an elevated level of eosinophils.

The next stage can have a duration of up to several years. Here the identification of the symptoms is influenced by the location of the localization of parasites, the features of their nutrition and numbers. Fixing on tissues of places of distribution, worms in man (photo - in the article) destroy them, causing an inflammatory reaction. And some rapidly developing species can cause irreparable harm to health and lead to disruption of the vital organs.

Diagnosis of the presence of parasites is made by revealing eggs and larvae with the help of fecal, sputum, etc. tests.
