Various types of parasites can be in the human body for a very long time, causing very specific damage to health.
A significant number of people suffer from severe diseases caused by parasites. At the same time, many have no idea about the presence of pests in the intestines and other organs.
Each type of parasite known to science has its own individual characteristics that an adult should know about.
Risk of infection
So far, science knows more than 200 species of parasites, which the human body is a habitat.
Ways and means of pest penetration to the most favorable place of residence have been studied in detail. We can say that each type of parasite has its "specialization".
Many helminths live in the gastrointestinal tract. There are also those that parasitize on the liver, lungs, and even the brain.
Almost all people are exposed to parasite attacks. It is equally likely that it will be an adult or a breastfed child.
The great danger is the presence of parasites in children. First of all, it reflects on the state of health. Babies often get sick for no apparent reason.
There is a delay in physical and mental development. It is not so easy to identify the cause of the discomfort, although it often “lies” in sight.
It is enough to perform certain studies, identify the type of parasite and prescribe a course of treatment.
A significant number of adults are at risk because their professional activities are related to the processing of raw materials contaminated with helminths.
Some species of parasites are very resistant to environmental influences and can be destroyed with great difficulty.
Pest varieties
The appearance of parasites in the human body is always accompanied by certain signs.
The peculiarity of this situation is that the symptoms are often very weak and it is difficult to detect the presence of pests without special studies.
The following helminth species parasitize on the body:
- circle;
- bar;
- flukes.
This classification is made taking into account external features, while, regardless of the species, parasites have a multitude of common features.
Hooks and suction cups of various shapes are designed to make it easier for parasites to fix their position in a certain place.
The life cycle of many parasites consists of several stages. Moreover, a species like tapeworm has two “owners” - a human and a pet.
Closed-loop migration provides these pests with the ability to exist and reproduce. In the process of movement, the parasite enters the human body and feeds on it.
This characteristic is characteristic of all microorganisms living in the intestines or other organs. Only beneficial species are involved in creative activities, and parasites in destructive activities.
Given these circumstances, people need to support beneficial and control pests.
Roundworms
Roundworms include roundworms. The parasite is orange in color and without teats.
The shape of the spindle allows it to migrate through various organs and penetrate the smallest openings and folds. This type of parasite can attack the lungs or pancreas.
Eggs laid by a roundworm are protected by a strong shell that can withstand the destructive effects of hydrochloric acid in the stomach. People most often become infected by eating unwashed vegetables and fruits.
Pinworm enters the human body in exactly the same way. In appearance it is a thin striped worm of pale gray color, growing to a length of 10 mm. Already in the larval stage, the parasite begins to harm humans.
Developing into a sexually mature individual, the larva secretes toxic enzymes that irritate the intestinal mucosa.
An adult worm can penetrate the deep layers of the small intestine and penetrate them. In such situations, a serious disease called peritonitis develops.
Another roundworm that parasitizes on the colon is the whipworm.
When swallowed, the following symptoms occur:
- headache and dizziness;
- persistent abdominal pain;
- sleep disorder.
Vlasoglav is named after its external characteristics - the worm is very thin and reaches a length of 50 mm. The parasite is the cause of trichocephaly.
The body never leaves the boundaries - the worm can only be destroyed, after which the parasite comes out along with the feces.
Ribbons
The occurrence of parasites in humans follows similar scenarios. Pork and beef tapeworms from the tapeworm form enter the body when they eat meat, ie pork and beef contaminated with Finns.
These Finns, or larvae, appear to be white bubbles and resemble millet semolina.
Reaching the intestine, the larvae take root and begin to develop into a full-fledged parasite. Development is asymptomatic in most cases.
After about three months, the tapeworm is already capable of producing offspring. This type of pest reaches a length of ten meters or more.
The presence of tapeworm in the body causes a serious disease of teniarchinosis. A more serious threat to human health is the tapeworm parasite of the Echinococcus type.
For this parasite, the human body is a temporary refuge. The main owners are animals - dogs and cats. People become infected through contact with beloved animals through food - mouth.
Upon reaching the intestine, the eggs begin to develop into larvae that have six fixation hooks.
They are transmitted through the bloodstream to various organs and are most often fixed in the liver and lungs.
Growing up, echinococcus begins to destroy surrounding tissues. Sometimes parasites large enough are replaced by a tumor.
Alveococcus is another representative of the tapeworm parasite in the human body. After penetrating the intestines, the larvae develop intensively and penetrate the walls of the small intestine, and are transmitted through the bloodstream to various organs and systems.
Like echinococcus, the parasite is fixed in the liver and begins its destructive activity.
The alveococcus has the shape of a multichambered bladder called a larvocyst. These larvae are able to attack the liver tissue and become cancer-like metastases.
Blood flow to the liver tissue is obstructed, necrosis begins, which poses a serious danger to human health and even life.
Fluke Worms
The list of tapeworms contains a separate type of parasite called fluke.
The following species are particularly dangerous flukes:
- cat fluff;
- fasciola;
- schistosome.
Liver pathologies are more common among human diseases than other organ diseases. The flakes got their name because of their anatomical structure.
There are several vacuum cups on the body of the parasite, with the help of which the pest is held in a certain place and penetrates deep into living tissues.
Feline flu is most commonly found in the gallbladder and pancreatic ducts.
Butterflies enter the human body along with fish that are not sufficiently salted or boiled.
In people affected by this pest, the temperature rises sharply, an unreasonable cough and rash appear on the body. If you do not take urgent action, then the person may die.
Fasciola is absorbed into the body by drinking unboiled water. In addition to pardoning the patient, it causes chronic jaundice.
Schistosomiasis, caused by a rare parasite, has become more common in recent years.
This fact is explained by the fact that a large number of people began to visit tropical countries where this pest is widespread.
Preventive measures
Medical practice shows that parasites take root much more often in the intestines than in other organs.
Pests of different species are able to adapt to existence in the liver, lungs, heart, brain, and even in the eyes - only this list gives a sufficient idea of the danger that parasites pose to human health and full life.
Different types of parasites can penetrate the body both individually and in combination, which increases the severity of the lesion.
To prevent any type of pest in your body, it is enough to respect the basic hygienic and sanitary requirements for food.
Young children should be kept under constant supervision, especially in summer when they go to land or to the sea.
Today there is no need to eat raw meat or fish, including stroganine. This atavism should be left in the past forever, so as not to expose your body to unnecessary risk.
