Types of parasites in the human body - what threatens us?

Parasites are organisms that live, eat and multiply inside their owner.Different types of parasites can live in fish, animals and man.They affect various organs and cause the development of many diseases.

Types of parasites in the human body

The danger of infection

Some people believe that the living of parasites in the human body is a normal phenomenon.This opinion is erroneous, since malicious parasites can significantly worsen the state of human health and lead to death.

In general, the danger of infection with parasites is as follows:

  1. Fast propagation leads to a decrease in all the protective functions of the body and its rapid exhaustion;
  2. The intake of nutrients is impossible, since they are absorbed by parasites;
  3. A sharp decrease in immunity leads to an exacerbation of chronic diseases, as well as the occurrence of many other diseases;
  4. The functions of many systems in the body are impaired;
  5. A long absence of treatment can lead to irreversible disorders in the work of various body systems, as well as to death.

Types of parasites

There are many malicious organisms that can settle within a person - they come in different shapes, sizes, differ in the place of localization, the method of nutrition, and so on.

Specialists classify several main types:

  • The simplest microorganisms can consist of only one or more cells, however, they lead to serious health problems;
  • The worms are flat;
  • Round worms;
  • ticks;
  • insects.

Naturally, for each of the cases of the disease, there are certain drugs.Before proceeding with treatment, it is necessary to conduct a detailed diagnosis and find out what kind of parasite belongs to.

Insects

This includes lice, fleas, gadflies.At the risk group of infection, small children are located - they are very sociable, in contact with many other children, and can also contact an infected person.In the vast majority of cases, a person is infected with lice and nits from another person.

Insects live on a person, so treatment in most cases does not provide for taking medications - there are enough use of local drugs.

Ticks

Another type of organisms parasitizing on a person is ticks.The most common disease caused by ticks is demodicosis.In this case, the defeat of the skin, mucous membranes and so on can be observed.

In a small amount, ticks on a person are not dangerous.Moreover, 90% of people are carriers of ticks.These smallest insects feed on dead skin cells, so they do not harm a person.However, if there is a sharp decrease in immunity, a change in the work of the body systems, a hormonal failure and so on, then the number of ticks can increase many times.In this case, they begin to eat living cells.If this happened, then the disease caused by ticks must be treated.

Treatment includes taking antibiotics, antihistamines, the use of ointments, drops (if the tick struck the organs of vision and nearby regions), as well as taking vitamins.

Demodex tick in humans

The simplest microorganisms

Parasites of this species are widespread everywhere - in water, on the ground, in the air.It is absolutely impossible to see them without a microscope, unlike insects and ticks.Many unicellular microorganisms do not harm any harm, such as the infusoria of the shoe or amoeba Proteus, while others are able to cause serious diseases.

The dysenteric amoeba and lamblia-these simplest parasites are localized in the organs of the gastrointestinal tract of a person, dog, cat or any other animal.They affect, as a rule, the liver and intestines.

The dysenteric amoeba enters the host’s body through poorly washed food, dirty hands, as well as when drinking unpeeled water.You can get infected directly, in domestic conditions, as well as with close contact with infected animals.

The dysentery amoeba multiplies very quickly and causes many unpleasant symptoms - liquid stool, bloating, nausea and vomiting, fever.

If you do not start timely treatment, then amoebiasis caused by dysentery amoeba leads to death due to dehydration.

Treatment consists in taking medications aimed at breeding amyuba, plentiful drink, as well as in the course of restoration of the microflora of the gastrointestinal tract and other zones of damage.

Helminths

The better name of this parasite is worms.

They are classified into three main types:

  1. Ensalmers.Such helminths have a small size and differ in a special structure - there are suction cups on their mouth and stomach, with which they eat, and are also attached to the walls of the host body.Localized saucers in the liver and duct of the gallbladder.
  2. Pourners of such a parasite are, most often, water inhabitants - fish and mollusks.In them, saucers live in the larval stage and do not cause them any inconvenience.The larva begins to develop when a person or animal enters the body.

    The main symptoms of the appearance of a saucer include headaches, a significant weight loss, and the gradual development of anemia.

  3. Ribbon worms.Helminths of this species are able to achieve huge sizes - up to 15 meters in length.They also exist in the form of a larva until they fall into the human body.
  4. In medical practice, there are often cases of infection with bull and pork chain.In this case, helminths affect the intestines, fixing on it with the help of suction cups.As a result, the parasite does not come out with feces, as is often the case with worms.

    Another strip worm is Echinococcus.Its difference is that the main danger is this parasite in the larval stage.Helmint can affect almost all systems, including lungs and brain.

    The danger of infection lies in the fact that the strip worms can not detect their presence in the body for a long time.The main symptoms of the disease are a change in the consistency of the stool, a change in appetite, weakness, a sharp decrease in immunity, exacerbation of chronic diseases;

  5. Round worms.The risk zone of infection with these helminths include small children who constantly play on the street, in the sandbox, exchange toys.Often round worms live in the soil, so they can enter the human body with dirty hands, when eating dirty vegetables and fruits.

Most often there are such roundworms as ascarides and pinworms.The symptoms of infection are the same as that of tape worms, but round worms are always accompanied by symptoms and can be found in feces.

Round Cheiovi in ​​the human body

Treatment of helminths of any kind is associated with the use of specific anthelmintic drugs.The doctor should prescribe the correct remedy and dosage, since many of the drugs are toxic and dangerous for an overdose.

Compliance with the main preventive measures will help to avoid infection with any parasites: eating meat and fish that have undergone heat treatment;the use of well -washed vegetables and fruits;Drinking water should be bottled or boiled.In addition, do not forget about the rules of personal hygiene and timely examination by the doctor.
