Parasites of the human body, the main types

Parasites often prevent a person from living normally because they greatly weaken the body. What representatives most often parasitize on us, as well as how to deal with them - the article will show.

Parasites are creatures that live and feed on their shelter. They can inhabit all animals, fish, birds, and humans. This causes a lot of problems because these creatures spoil a lot of health. Parasites in the human body can live in the liver, intestines, blood, and even attack the brain and lungs. What are the most common types? There are several different categories of parasites: flatworms, protozoa and insects. How they affect the body and how to expel them - the article will show.

Types of parasites

the simplest parasite of trypanostomy in humans

As already mentioned, there are different types of parasites in the human body:

  • protozoa (trypanosoma, malaria plasmodium, lamblia, amoeba design);
  • flatworms (lean meat, liver, beef and pork ribs);
  • round worms (round worms, worms);
  • insects (lice, gadfly, fleas);
  • chelicerae (mites).

These species most often attack the human body. They are all united by the fact that they feed on the fluids and tissues of their host, killing it slowly. Difficultly it is difficult to expel any of them, because each has many bonding devices (suckers, hooks, kelicera), and some are even placed in the cells of the body, from where it is simply impossible to expel them.

Probably everyone knows about lice, fleas and ticks because these creatures live on the surface of the body, are easy to find, and are a little easier to fight. But not everyone is aware of the body's internal parasites, and in fact they are the most dangerous to health.

The simplest

These tiny organisms are found everywhere:

  • in water;
  • toka;
  • air

It is impossible to see them because they are made up of only one cell. There are harmless representatives: eyelash boots, proteus amoeba, green euglena and others. Some even help animals, for example, some ciliates dissolve cellulose from grass for cows, but there are many parasites among this abundance.

Plasmodium and malaria

plasmodium of malaria in the human body

This Central African native haunts many countries today. Plasmodium malaria is transmitted by mosquitoes of the genus Anopheles, which are not very selective and the main thing for them is heat and water. Many countries carry out disease prevention: they drained the swamps, destroyed the larvae and the disease spread there, but this parasite is still raging in the region of Central Africa and South America.

Once in the body, the malaria plasmodium goes through two stages: hepatic and erythrocytes. The first passes after a few hours. Plasmodium attacks the liver cells, enters them, begins to multiply and feeds on the host nutrients. At this time, a person already feels the first unpleasant symptoms:

  • headache;
  • mixed;
  • lack of appetite.

After a few days, the parasite leaves the liver in the bloodstream and settles in the red blood cells. He lives there for a long time. Every 3-4 days he leaves one and enters the other. Exodus is accompanied by the release of protozoan waste products, therefore, the owner's temperature rises rapidly and vigorously, begins fever, vomiting and intestinal disorders.

Treating Plasmodium malaria is difficult because the parasite hides in the host cells. When the main symptoms of the disease appear, it is necessary to call an ambulance and constantly water the patient before its arrival, because the temperature and fever cause dehydration. A type of plasmodium will be installed in the hospital (there are more than 5 of them) and treatment will be prescribed.

Prevention is simple - enclose your habitat with a mosquito net if there are breeding grounds for Anopheles mosquitoes in the area, as well as draining swamps or flooding their surface with special tools that create a film through which mosquito larvae do notthey can breathe and die.

Giardia and the amoeba of dysentery

lamblia in the human body

Both of these parasites live in the human digestive organs, and any animal can become their host. They penetrate the body along with contaminated water, unwashed fruits or vegetables. Their favorite sites are the liver ducts, the small intestine, and the upper part of the large intestine.

The symptoms will not linger long and it is difficult not to notice them. The first manifestations are bowel disorders. Over time, the temperature rises sharply, severe diarrhea and vomiting begin. Most often, a person dies from dehydration, because the last two symptoms practically do not stop, the patient quickly loses water.

The fight against these parasites consists of drinking plenty of clean boiled water and taking special packets of salt - preparations that contain a special composition of salts that help retain water in the body. Prevention is also simple - washing products, monitoring the condition of drinking water, because it is what is the source of reproduction of these parasites.

Flatworms

Parasites in the human body can be unicellular and multicellular. These are flatworms. The name comes from their shape because they are really flat because they breathe with the entire surface of the body, so try to reduce the volume as much as possible. There are 3 types of flatworms: eyelashes, lightning bolts and tapeworms. The former are quite harmless, they live on land or water. But the second two classes are exclusively parasites.

Progeny

These are small worms that have suckers in their mouth and abdomen. They prefer to live in our body inside the liver and gallbladder canal. These helminths have two main stages of life - a larva and an adult. The host for the larvae can be water mollusks (liver fat), fish (cats), but livestock and humans are permanent.

hepatic fluke in humans

Adults are most often placed in the area of the liver, but sometimes they can enter the intestines, lungs, and even the brain. Their accommodation is accompanied by:

  • headache;
  • weight loss;
  • lack of appetite;
  • anemia

They can only be killed by special anthelmintic drugs, which the doctor will prescribe, depending on the type of parasite.

Prevention is simple: do not drink water and do not try to swim in bodies of stagnant water, and also do not chew on grass edges in the field, as many people like to do, because worm larvae can also be on the grass.

Tape

Tapeworms are so named because these parasites have a large length (excluding the echinococcus), so they really look like a ribbon. They also develop with a change of "residence", but more often it is the person who is the permanent owner for them.

Bovine and porcine tapeworms attack the small intestine. They are attached with suction cups and hooks, so they can not be pulled out of there with feces. They are constantly growing, can reach a length of 10 meters or more. They can be expelled from there only with special medicines that will kill the parasite, the suckers will relax, fall off and come out with feces.

One of the most dangerous representatives of worms is the echinococcus. The host of its larva is man and herbivores, and the adult worm settles on predators. The stagnant larval stage of the parasite is dangerous because it differs in structure from that which forms the tapeworm.

Echinococcal larvae are a sac in which many larvae develop. Such a structure can attack the brain, lungs, intestines, liver. It is dangerous with its unlimited growth because sooner or later it simply tears the owner's tissues. If the echinococcus has struck the brain or lungs, then only one operation can save the patient, but it can also be dangerous.

If tapeworms are lodged in our body, then we urgently need to go to the hospital because they are constantly growing, blocking the intestines (worms), affecting the lungs or brain (echinococcus), drinking all the vital fluids andkilled their host. Prevention consists of controlling meat and fish for small white or yellow larvae. If such are present, then such a product should never be eaten!

Round worms

Ascaris in the human body

Many have also heard of roundworms because they poison people’s lives no less often than flatworms, especially young children suffering from them. The most "famous" representatives are roundworms and worms, which inhabit the human intestines. Sometimes they can enter other organs: liver, eyes, brain.

Roundworms develop with a change in habitat: the larvae live in a person’s lungs and the adults in the intestines. The name "round" characterizes their transverse shape - they are really round.

These worms do not have attachment devices, but have muscles that help them resist defecation. Sometimes they themselves crawl out of the body (pinworm) and lay eggs in the anus.

It is the children who suffer from them because the babies do not know the rules of hygiene, therefore, after brushing the place where the eggs are stored, they can pull their fingers into the mouth and become infected again.

Treatment is possible with medication prescribed by a doctor. If the mother of a baby with worms is afraid to give her pills, then you can cure her without them. To do this, it is necessary at 5-6 in the morning (it is at this time for the female to leave the body and lay eggs around the anus) to wipe the inside of the priests with vodka, and then lubricate the treatment sitewith baby cream to not dry delicate skin.

Prevention consists in the fact that you need to constantly monitor hygiene: wash your hands after touching the ground, do not drink contaminated water.

Parasitic tests

If you have doubts about your health, you can be tested for the presence of parasites in the body. If any of the following symptoms are present, place a plus sign.

  1. Weight loss will be followed by diet or dietary changes.
  2. The temperature is constantly rising in the region of 37-37. 5 grams.
  3. There is no appetite or, conversely, you constantly want to eat.
  4. There is often a desire to eat something sweet.
  5. Increased headaches.
  6. Hot flashes of weakness.
  7. Stool disorders.
  8. Nausea or vomiting
  9. Allergic rash or swelling.
  10. Pain in the liver and intestines.
  11. Fainting (if the brain is affected).
  12. Shaky hands.
  13. Continuous fading.

If there are from 1 to 4 plus, then it means that there are no worms, but the person is experiencing constant stress, is ill or has problems with the digestive tract. If there are 5 to 7 plus, then there is a suspicion of the presence of parasites, but more than 8 positive answers indicate real problems, hence an urgent need to consult a doctor.

Parasites poison the human body, weaken the immune system, prevent them from leading a normal active life, so you need to remember about the symptoms of their manifestation and methods of treatment, as well as preventive measures, because only then can you protect yourself and your family. jote.
