It is necessary to start with the fact that the simplest organisms appeared since time immemorial, they are considered the most ancient inhabitants of the planet. Throughout their existence, they become very resistant to various tests. They can survive even in the most dangerous environments.
These microorganisms have chosen a very easy way of life for themselves - parasitism, especially in the human body. As mentioned before, these microorganisms are very "dangerous" and persistent, so sometimes it is so difficult to get rid of them.
There are several types of "dwelling" parasites. The first type includes endogenous microorganisms, that is, those that are in the human body. The second type includes exogenous parasites that easily "settle" on the skin and cause various skin diseases.
Types of protozoan parasites
Basically, there are 4 types of parasites that "live well" in the human body.
Flagellate
These include lamblia, trypanosomes. This class is the most ancient representative of parasites. They get this name thanks to their locomotor organ: the flagella. The size of the parasites themselves is only microscopic, they have a fixed shape, and reproduce, as a rule, by dividing into two parts.
They are very dangerous to humans and animals, if they get into their bodies, they will cause great danger. They also cause various diseases. Such as American carotid fever, cutaneous leishmaniasis, and more. They can do parasites on the intestines, blood, and skin. Therefore, have a negative impact on human health.
Sporozoans
Protozoan parasites of this type have a very complex path of expansion. This class is known to contain about 1400 species. All representatives "choose" the way of life of parasites and are very dangerous for humans and animals. Reproduction occurs by cell division.
Often, the tissues and organs of a person or animal are chosen as "dwellings". This species causes many diseases. For example, such as malaria, toxoplasmosis.
Ciliates
This includes balantidia. There are about 7000 different species. The organ of movement of this parasite is the cilia, of which there are many.
A feature of this type is the presence of two cores. They have a fixed body shape and shell. Breeding is usually done by division. This species is no less dangerous to humans and animals than before.
Sarawak Code
These include dysentery amoeba. They are the most primitive of all types and classes. There are about 10, 000 different species! They do not have a permanent body shape. Parasites in humans and animals.
Often, they choose the digestive system for their activities. Because of them, a person can suffer from very serious poisoning. In some cases, death is also common.
This type combines high resistance to various "tests". After all, infected people always try to fight parasites, but not always effectively because of how much they can withstand all the steps.
Why they are dangerous, what diseases cause them
The simplest parasites are indeed very dangerous to human health. They can cause a variety of diseases that carry certain consequences. You should not underestimate the simplest parasite, as it can harm a person significantly.
Diseases caused by protozoan parasites:
Malaria
For such diseases, certain differences are characteristic. Sometimes there is relief, then relief is replaced by worsening symptoms. The main symptoms are headache, fever, nausea, vomiting, seizures.
For years, chitin was considered the best treatment. However, there are also deaths from this disease most often where drugs are developed at low levels.
Amebiasis
Other diseases that are no less dangerous, the consequences can also be depressing. The causative agent is amenta dysentery.
Symptoms begin to appear 7 to 10 days after infection. These include headaches, general malaise, fever, and some people may experience abdominal pain. This is followed by complications, which are expressed in liver problems. If the patient does not start treatment on time and does not see a specialist, then the consequences will be irreversible.
Toxoplasmosis
The causative agent of this disease is Toxoplasma Gondia. Symptoms of the disease include eye damage, aching nervous system, and even the cardiovascular system. Often, at first, the infection is invisible, as if the common cold had passed.
Infections during pregnancy are very dangerous. Even if the child is safe, there is a high probability of complications and damage to the eyes or nervous system. Therefore, even with the first symptoms, it is important to see a doctor.
Balantidiasis
It is caused by microorganisms such as balantidia. The symptoms of this disease are abdominal pain, digestive disorders. In some cases, high temperature, body intoxication may also occur.
Leishmaniasis
Leishmania is considered to be the causative agent of this disease. With cutaneous and mucocutaneous manifestations, abscesses appear. With mucocutaneous manifestations, edema often occurs. Since the disease is related to the respiratory tract, there may be death.
Leishmaniasis is mainly found in hot countries. The disease is quite common and occurs in 87 countries.
As you can see, the simplest parasites are very dangerous to human health, even the simple structure of microorganisms. They can cause irreparable harm to the human body, as well as cause certain consequences and complications.
How it is delivered
There are 4 most common ways of infection:
- Contact - household. . . This type is indicated for violation of hygiene measures or hygiene rules. Infections can occur from a variety of activities: the use of other people’s items, especially personal hygiene products, tableware and the like. Therefore, it is very important to adhere to the rules of personal hygiene, have your own personal care products and in case you do not use other people's products.
- Fecal - oral. . . This type occurs as a result of contact with feces or vomiting. The simplest parasite first enters the hands or food of the "new host", and then into his body.
- From food. . . This type manifests itself by eating contaminated food. These can be undercooked fish or meat, unwashed vegetables and fruits, dairy products.
- Can be sent. . . This type occurs as a result of transmission from an infected object during a bite, i. e. through salivary secretions.
How to get rid of them
After reading the article, this question must have arisen. Infections with the simplest parasites are very common, so the question of getting rid of them is very relevant.
As mentioned earlier, when the first symptoms of infection appear, you should see a doctor. Specialists can prescribe specific tests and examinations. After overcoming it, the doctor will make an accurate diagnosis. After that, the urgent need to continue treatment. It is also not recommended to self -medicate, as a professional can help make an accurate diagnosis and provide appropriate treatment. In most cases, doctors use treatment with a variety of drugs that help get rid of parasites and speed up human recovery.
In these modern times, there are many good medications that can help infections with protozoan parasites. There are many types of medications on the market, which make it possible to get the right medication for a particular patient.
Preventive measures
In order not to face the above problems, it is very important to adhere to certain rules, and also take precautionary measures.
The most effective rules are the rules taught by children in school. First of all, you can’t forget to wash fruits and vegetables thoroughly. You can also heat treatment or cut the skin.
You should also not eat raw fish, not fully cooked meat. It is important to prepare the dish completely, adhering to the rules and temperature time, to cook the product completely. Casual sex should be avoided. And you also need to undergo regular medical checkups.
