Various types of parasites can remain in the human body for a long time, causing very specific damage to health.
A significant number of people suffer from serious diseases caused by parasites. At the same time, many have no idea of the presence of pests in the intestines and other organs.
Each parasite species known to science has its own individual characteristics that an adult must know.
Risk of infection
Today, science knows more than 200 species of parasites, for which the human body is a habitat.
The ways and means of pest penetration to the most favorable place of stay 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 the liver, lungs and even the brain.
Almost everyone is subject to attacks by parasites. It is also likely to be an adult or a breastfed baby.
A great danger is the presence of parasites in children. Firstly, this is reflected in 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 disease, although it is often "in plain sight".
Just do some studies, identify the type of parasite and prescribe a course of treatment.
A significant number of adults are at risk, as their professional activity is associated with the processing of raw materials contaminated with helminths.
Some species of parasites are highly resistant to environmental influences and can be destroyed with great difficulty.
Varieties of pests
The appearance of parasites in the human body is always accompanied by some signs.
The peculiarity of this situation is that the symptoms are usually very weak and it is difficult to detect the presence of pests without special studies.
The following types of helminths parasitize the body:
- round;
- tape;
- chance.
This classification was compiled taking into account the external characteristics, although, regardless of the species, the parasites have many common characteristics.
Hooks and suction cups of different 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. In addition, a species like the tapeworm has two "owners" - a man 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 inherent in all microorganisms that live in the intestines or other organs. Only useful species are included in creative activity, and parasites are included in destructive activity.
Given these circumstances, humans need to support benefits and suppress pests.
Roundworms
Roundworms include the roundworm. It is an orange colored parasite and without suction cups.
The shape of the spindle allows it to migrate through various organs and penetrate the smallest holes and folds. This type of parasite is able to invade the lungs or the pancreas.
The eggs laid by worms are protected by a strong shell that can withstand the destructive effects of hydrochloric acid in the stomach. Most of the time, people are infected by eating unwashed fruits and vegetables.
Pinworm enters the human body in exactly the same way. In appearance, it is a thin striped worm of a light gray color, growing in length up to 10 mm. In the larval phase, the parasite begins to harm humans.
Becoming a mature specimen, the larva secretes toxic enzymes that irritate the intestinal mucosa.
An adult moth is able to penetrate the deep layers of the small intestine and penetrate it completely. In situations like this, a serious disease called peritonitis develops.
Another round parasite that parasites the large intestine is the whipworm.
When ingested, the following symptoms appear:
- headache and dizziness;
- persistent abdominal pain;
- sleep disorder.
Vlasoglav's name is due to its external characteristics - the worm is very thin and reaches 50 mm in length. The parasite is the causative agent of trichocephalosis.
The body never leaves the limits - the worm can only be destroyed, after which the parasite leaves with the feces.
Tapeworms
The appearance of parasites in humans follows similar scenarios. Swine and bovine tapeworms in the form of tapeworms enter the body when eating meat, pork and beef contaminated by the Finns, respectively.
In appearance, these Finns, or larvae, are white bubbles and resemble corn groats.
Upon reaching the intestines, the larvae entrench themselves and begin to develop into a complete 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 teniarinosis. A more serious threat to human health is the Echinococcus ribbon parasite.
For this parasite, the human body is an intermediate refuge. The main owners are animals - dogs and cats. People are infected through contact with their beloved animals through food - through the mouth.
Upon reaching the intestine, eggs begin to develop into larvae, which have six hooks for attachment.
With the bloodstream, they are transported to various organs and, in most cases, are fixed in the liver and lungs.
As the echinococcus grows, it begins to destroy the surrounding tissues. Sometimes parasites large enough are mistaken for a tumor.
Alveococcus is another representative of the parasite streak in the human body. After penetrating the intestine, the larvae develop intensely and penetrate the walls of the small intestine and are transported through the bloodstream through various organs and systems.
Like echinococcus, the parasite attaches itself to the liver and begins its destructive activity.
Alveococcus takes the form of a multiple-chambered bladder called the larvocyst. These larvocysts are able to invade liver tissue and become cancer-like metastases.
The blood supply to the liver tissue is interrupted, necrosis begins, which represents a serious danger to health and even human life.
Worms Fluke
The tapeworm list contains a separate species of parasite called worms.
The following species are particularly dangerous worms:
- chance of the cat; fasciola;
- schistosoma.
Liver pathologies are more common among human diseases than other organ diseases. The worms received this name due to their anatomical structure.
In the parasite's body there are several suction cups, with the help of which the pest is kept in a certain place and penetrates deeply into living tissues.
Feline worm is most commonly found in the gallbladder and pancreatic ducts.
Fluke enters the human body along with fish that have not been sufficiently salted or boiled.
In people affected by this pest, the temperature rises sharply, an irrational cough appears and skin rashes appear on the body. If you do not take emergency measures, the person may die.
Fasciola is absorbed by the body when drinking unboiled water. With the patient's collusion, 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 started to visit the tropical countries where this pest is spread.
Preventive measures
Medical practice shows that parasites take root in the intestines much more frequently than in other organs.
Pests of various types are able to adapt to exist 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 enter the body either individually or in combination, which increases the severity of the injury.
To avoid pests of any kind on your body, just follow the basic rules of hygiene and sanitary requirements for food.
Young children should be kept under constant supervision, especially in the summer, when they go to the countryside or the sea.
Today there is no need to eat raw meat or fish, including sliced meat. This atavism must be left in the past forever, so as not to expose your body to unwarranted risks.
