It is necessary to start with the fact that the simplest creatures appeared so long ago, they are considered the most ancient inhabitants of the planet. During their lifetime, they have become extremely resistant to various tests. They can survive even in the most dangerous environments.
These microorganisms have chosen a very convenient way of existence for themselves - parasites, especially in the human body. As mentioned earlier, these microorganisms are extremely "harmful" and persistent, so sometimes it is difficult to remove them.
There are several types of parasites that "reside". The first includes endogenous microorganisms, that is, the microorganisms inside the human body. The second includes exogenous parasites that readily "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.
Whip
These include lamblia, trypanosomes. This class represents the oldest representatives of the parasite. They got this name because of their moving organ: the whip. The size of the parasites is simply very small, they have a constant shape and reproduce as a rule by dividing into two parts.
They are very dangerous to humans and animals, if entering their body will cause enormous harm. They also cause many different diseases. Carotid artery fever in the United States, for example, skin leishmaniasis, and many others. They can parasitize in the intestines, in the blood, and on the skin. As such, negatively affects human health.
Sporozoans
This single-celled parasite has a very complex path of development. The currently known class has around 1, 400 species. All representatives "choose" to live parasitic and extremely dangerous for humans and animals. Reproduction occurs by dividing cells.
Usually, human or animal tissues and organs are chosen as "habitat". This species causes many diseases. For example, such as malaria, toxoplasmosis.
Branch
These include balantidia. There are about 7, 000 different species. The moving organ of these parasites is the cilia, in which there are many.
A feature of this type is the presence of two nuclei. They have a constant body shape and shell. Reproduction is usually done by division. This species is as dangerous to humans and animals as compared to the previous two.
Sarcode
These include amoebic dysentery. They are the most primitive of all types and grades. There are about 10, 000 different species! They do not have a permanent body shape. Parasites in humans and animals.
Usually, they choose the digestive system for their activities. Because of them, a person can be very poisoned. In some cases, death is also common.
These types combine high resistance with many different "tests". After all, an infected person constantly tries to fight off the parasite, but it is not always successful because of how many measures they can endure.
Why are they dangerous, what diseases do they cause?
The simplest parasites are indeed very dangerous to human health. They can cause many different diseases with certain consequences. In any case, you should not underestimate the simplest parasites, because they can significantly harm a person.
Diseases caused by protozoan parasites:
Malaria
For such a disease, a certain difference is characteristic. Sometimes there is remission, then remission is replaced with worse symptoms. The main symptoms are headache, fever, nausea, vomiting, convulsions.
For many years, chitin has been considered the best treatment. However, there are also deaths from the disease most often in places where low-level medicine is developed.
Amebiasis
Another disease is equally dangerous, its consequences are sad. The causative agent is amoebic dysentery.
Symptoms appear 7 to 10 days after infection. These include headache, general malaise, fever and some people may experience abdominal pain. Followed by complications, manifested in liver problems. If the patient does not conduct treatment on time and does not go to a specialist, the consequences will be irreversible.
Toxoplasmosis
The causative agent is Toxoplasma of Gondia. Symptoms of this disease include damage to the eyes, the affected nervous system, as well as the cardiovascular system. Very often, at first, the infection is negligible, as if a common cold has passed.
Infection during pregnancy is very dangerous. Even if the child survived, the child most likely experienced complications and damage to the eyes or nervous system. So, even with the first symptoms, it is imperative to consult a doctor.
Balantidiasis
It is caused by a microorganism such as balantidia. Symptoms of this disease are abdominal pain, indigestion. In some cases, high temperature, body poisoning can also occur.
Leishmaniasis
Leishmania is considered to be the cause of this disease. With skin and mucosal manifestations, sores appear. With mucosal manifestations, edema is often possible. Since these diseases are related to the respiratory tract, death is possible.
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 extremely dangerous to human health, despite the simple structure of microorganisms. They can cause irreversible harms to the human body, as well as lead to certain consequences and complications.
How they are transmitted
There are 4 most common ways of infection:
- Contact - household. . . This category is manifested by a violation of sanitary measures or hygiene rules. Infection can result from different activities: using other people's things, especially personal hygiene products, dishes and the like. Therefore, it is very important to follow the rules of personal hygiene, have your own personal care products and in no case should you use others.
- Feces - mouth. . . This occurs as a result of contact with feces or vomit. The simplest parasite first enters the hands or food of the "new host", then enters his body.
- From food. . . This type manifests itself through ingestion of contaminated food. These can be undercooked fish or meat, unwashed vegetables and fruits, dairy products.
- Can be transmitted. . . This occurs as a result of transmission from an infected object through the bite, that is, through the production of saliva.
How to get rid of them
After reading the article, this question definitely arises. The simplest parasitic infections are very common, so the question of their elimination is extremely relevant.
As mentioned earlier, when the symptoms of infection first appear, you should consult a doctor. A number of tests and tests may be ordered by the specialist. After passing them, the doctor will make an accurate diagnosis. Then there is an urgent need to conduct treatment. It is also not advisable to self-medicate because someone who has expertise is required to help make an accurate diagnosis and prescribe appropriate treatment. In most cases, doctors have to treat with a variety of drugs that help eliminate parasites and speed up human recovery.
In modern times, there are many different good drugs that help to treat protozoa parasitic infections. There are many drugs on the market, making it possible to find the right one for a particular patient.
Precautions
In order not to face the above problems, it is imperative to comply with certain rules, as well as take precautions.
The most effective rules are those taught by children in school. First of all, you should not forget to thoroughly wash the fruits and vegetables. You can also heat treatment or cut the skin.
Furthermore, you cannot eat raw fish, fully undercooked meat. It is imperative to completely prepare the food, adhere to the temperature and time regime in order to fully cook the product. Avoid casual sex. And you also need to have regular checkups.
