Worms that, parasitizing, develop and live in the body of plants, animals and humans, are usually called "helminths" in medicine, but in the people they are just worms. The diseases caused by them are common throughout our planet.
Types of parasites
According to statistics, more than a billion people are infected with 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, round and tapeworms. Before choosing a method of disposal, you need to figure out 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, both free-living and parasitic.
The name of the type was given by a round shape, which can be seen on the cross section. These are worms with a thin elongatedlength and pointed at both ends of the body. The most common representatives of this type, which parasitize in the human body, are trichina, human roundworm, whipworm, pinworm children. Here you need to find out what the worms look like in humans.
The body of roundworm can reach forty centimeters, while 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 metabolic toxins.
The pinworm 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 worm is quite common in children.
But the most dangerous types of roundworms for humans are whipworm and trichina.
The 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 size of these worms can reach one and a half meters. These parasites usually enter the human body by eating undercooked or raw fish or crayfish. They 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 it with suction cups (twoor sets, depending on the species). These worms have a well-developed digestive, reproductive, nervous systems and practically no respiratory and circulatory systems. They feed on the blood of the host, the contents of its intestines, epithelium or mucus. This is what worms look like on a human.
The name of these helminths was given inaccurately, since they do not suck anything out of the body. But despite this, the damage they cause is enormous. The intermediate host of such worms are molluscs, then fish, and the final host is vertebrates, including humans.
Tape worms in humans
Just like the flukes described above, these are flatworms, subdivided into tapeworms and tapeworms. Unlike round ones, these have an intermediate host (animals and fish). It is in his body that the larvae develop. Being in a sexually mature state, they usually live in the intestines of a vertebrate.
The body of such helminths is divided into segments. The head is an attachment organ, and then comes the growth zone, so the parasite feeds on the surface of the body, and the food digested by the host becomes food for it. From digestion in the human body, such a worm (as well as many other types of parasites) is saved by the antikinase secreted by it, which neutralizes the pancreatic juice. But in diagnostic terms, when identifying parasites, the differences between tapeworms and tapeworms are most important.
The latter are characterized by a head (scolex), which has two suction grooves or fossae at the anterior end of the helminth. The eggs are released intothe external environment due to the fact that the uterus has its own opening. When examining bowel movements, they can be found.
Because of their appearance, they were called tapeworms. A ribbon-like, segmented body is their characteristic feature. This worm can be up to eighteen meters long.
With the help of four suction cups located on the head, it is attached to the walls of the intestines. And behind it is the neck, as it grows, segments form. Finding the eggs of these parasites is very difficult due to the fact that the uterus does not have a excretory opening. This is what worms look like on a human.
Determination of parasitic infestation
These worms are characterized by three stages of development. Initially, there is an egg, from which subsequently a larva appears in the intestine, which then migrates to a permanent habitat (various organs). After that, the helminths develop into 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 parasites came from 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, geohelminthiases - those that enter the body from the ground on poorly washed plants, biohelminthiases - that enter through the meat of affected animals or fish.
Signs of the presence of parasites in the human body
Usually, the signs of damage depend on the stage of development of the worms themselves. This disease has an acute and acquiredstages. The first can last up to three weeks and is characterized by an allergic rash, a suffocating dry cough, and an increased level of eosinophils in the blood.
The next stage can last up to several years. Here, the location of the parasites, the characteristics of their nutrition and abundance affect the identification of symptoms. Fixing on the tissues of the places of distribution, worms in humans (photo - in the article) destroy them, causing an inflammatory reaction. And some fast-growing species can cause irreparable harm to he alth and lead to disruption of vital organs.
Diagnosis of the presence of parasites is made by identifying eggs and larvae using stool, sputum, etc.
