It is necessary to start with the fact that the simplest organisms appeared a long time ago, they are considered the oldest inhabitants of the planet. During the entire period of their existence, they have become incredibly resistant to various tests. They can survive even in the most dangerous environment.
These microorganisms chose a very convenient way of existence for them - parasitism, particularly in the human body. As mentioned earlier, these microorganisms are incredibly "harmful" and persistent, so it is sometimes very difficult to get rid of them.
There are several types of parasite "residence". The first type includes endogenous microorganisms, that is, those that are inside the human body. The second type 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.
Scourged
This includes lamblia, trypanosomes. This class is a representative of the oldest parasite representatives. They received this name thanks to their organ of movement: scourges. The size of the parasites themselves is simply microscopic, they have a constant shape and reproduce, as a rule, dividing into two parts.
They are very dangerous for humans and animals, if they enter their bodies, they cause enormous damage. They also cause several diseases. Like American carotid fever, cutaneous leishmaniasis and many others. They can parasitize in the intestines, in the blood and on the skin. Thus, negatively affecting human health.
Sporozoa
This type of protozoan parasite has a very complex development path. The class is currently known to contain approximately 1400 species. All representatives "choose" a parasitic way of life and are extremely dangerous to humans and animals. Reproduction occurs by cell division.
Most of the time, the tissues and organs of a person or animal are chosen as a "place of residence". This species causes many diseases. For example, like malaria, toxoplasmosis.
Ciliates
This includes balantidia. There are about 7, 000 different species. The organs of movement of these parasites are the cilia, which are many.
A characteristic of this type is the presence of two nuclei. They have a constant body shape and shell. Reproduction is usually performed by division. This species is no less dangerous to humans and animals than the previous two.
Sarcode
This includes amoeba dysentery. 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. Parasite in humans and animals.
Most of the time, they choose the digestive system for their activities. Because of them, a person can suffer very serious intoxications. In some cases, deaths are also common.
These types combine high resistance to various "tests". After all, an infected person constantly tries to fight the parasites, but it doesn't always work out because of how much they can handle all the measures.
Why are they dangerous, what diseases do they cause
The simplest parasites are actually very dangerous to human health. They can cause various diseases that have certain consequences. In no case should you underestimate the simplest parasites, because they can cause significant harm to a person.
Diseases caused by protozoan parasites:
Malaria
For such a disease, certain differences are characteristic. Sometimes there is relief, and then the relief is replaced by worsening symptoms. The main symptoms are headache, fever, nausea, vomiting, seizures.
For many years, chitin was considered the best treatment. However, there are also deaths from this disease, most of the time, when medicine is developed at a low level.
Amebiasis
Another disease no less dangerous, whose consequences can also be sad. The causative agent is amoebic dysentery.
Symptoms begin to appear 7 to 10 days after infection. These include headache, malaise, fever and some people may experience stomach pains. This is followed by complications, which are expressed in liver problems. If the patient does not start treatment at the right time and does not seek a specialist, the consequences will be irreversible.
Toxoplasmosis
The causative agent of the disease is Gondia's Toxoplasma. The symptoms of this disease include eye damage, the nervous system suffers, as well as the cardiovascular system. Often, at first, the infection is normal, as if a common cold has passed.
Infection during pregnancy is very dangerous. Even if the child survives, complications and damage to the eyes or nervous system is more likely. So, even with the first symptoms, it is essential to see a doctor.
Balantidiasis
It is caused by a microorganism such as balantids. The symptoms of this disease are abdominal pain, indigestion. In some cases, a high temperature, intoxication of the body is also possible.
Leishmaniasis
Leishmania is considered the causative agent of this disease. With cutaneous and mucocutaneous manifestations, ulcers appear. With mucocutaneous manifestation, edema may occur frequently. As these diseases are associated with the respiratory tract, deaths can occur.
Leishmaniasis is found mainly in warm countries. This disease is quite common and occurs in 87 countries.
As you can see, the simplest parasites are incredibly dangerous to human health, despite the simple structure of microorganisms. They can cause irreparable damage to the human body, in addition to causing certain consequences and complications.
How they are transmitted
There are 4 most common forms of infection:
- Contact - family. . . This type manifests itself due to the violation of sanitary measures or hygiene standards. Infection can occur from a variety of activities: the use of other people's things, especially personal care products, dishes and the like. Therefore, it is very important to follow personal hygiene rules, to have your own personal hygiene products and in no case to use someone else's.
- Fecal - oral. . . This type occurs as a result of contact with feces or vomiting. The simplest parasite enters the "new host "'s hands or food first and then into its body.
- Of food. . . This type manifests itself as a result of eating contaminated food. They can be undercooked fish or meat, unwashed vegetables and fruits, dairy products.
- Transmissible. . . This type occurs through the transmission of an infected object during a bite, that is, through the secretion of saliva.
How to get rid of them
After reading the article, that question certainly arises. Infections with the simplest parasites are very common, so the issue of getting rid of them is extremely relevant.
As mentioned earlier, when the first symptoms of infection appear, you should see a doctor. The specialist can prescribe certain tests and exams. After going through them, the doctor will make an accurate diagnosis. After that, an urgent need to proceed with treatment. Self-medication is also not recommended, as it is a professional who is able to help make the correct diagnosis and prescribe an appropriate treatment. In most cases, doctors resort to treatment with various medications that help eliminate parasites and accelerate human recovery.
In modern times, there are many good drugs that help with infections by protozoan parasites. There is a wide variety of medications on the market, which allows you to find the right medication for a particular patient.
Preventive measures
In order not to face the above problems, it is essential to comply with some rules, as well as the adoption of preventive measures.
The most effective rules are those taught by children at school. First of all, one must not forget the complete washing of fruits and vegetables. You can also do a heat treatment or cut the skin.
In addition, you cannot eat raw fish or fully cooked meat. It is essential to fully prepare the dish, observe the temperature regime and the time, so that the product cooks completely. Casual sex should be avoided. And you also need to undergo regular medical checkups.
