It is necessary to start with the fact that the simplest organisms appeared long ago, they are considered the most ancient inhabitants of the planet. Throughout the period of their existence, they have become extremely resistant to various tests. They can survive even in the most dangerous environment.
These microorganisms have chosen a very suitable way of existence for themselves - parasitism, especially in the human body. As mentioned earlier, these microorganisms are extremely "harmful" and persistent, so sometimes it is so difficult to get rid of them.
There are several types of "habitat" of parasites. The first type involves endogenous microorganisms, that is, those that are inside 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.
standard-bearer
These include lamblia, trypanosomes. This class is a representative of the most ancient representatives of parasites. They got this name thanks to their organ of movement: flagella. The size of the parasites themselves is purely microscopic, they have a constant shape and reproduce, as a rule, being divided into two parts.
They are very dangerous to humans and animals, if they enter their body, they cause great harm. They also cause various diseases. Such as American carotid fever, cutaneous leishmaniasis and many others. They can parasitize the intestines, blood and skin. Thus, adversely affecting human health.
Sporozoans
This type of protozoan parasite has a very complex path of development. 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 often, the tissues and organs of a person or animal are selected as "habitat". This species causes many diseases. For example, such as malaria, toxoplasmosis.
Ciliateve
These include balantidia. There are about 7000 different species. The organs of movement of these parasites are cilia, of 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 carried out by division. This species is no less dangerous to humans and animals than the previous two.
Sarkodie
These include the amoeba of 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. Parasitizes humans and animals.
Most often, they choose the digestive system for their activities. Because of them, a person can experience very serious poisoning. 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 does not always work because of how much they can resist all measures.
Why they are dangerous, what diseases they cause
The simplest parasites are really very dangerous to human health. They can cause various diseases that bring certain consequences. Under no circumstances should you underestimate the simplest parasites, as they can significantly harm a person.
Diseases caused by protozoan parasites:
Malaria
For such a disease, certain differences are characteristic. Sometimes there is relief, then relief is replaced by worsening of 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 this disease more often where medications are developed at a low level.
Amebiaza
Another no less dangerous disease, the consequences of which can also be sad. The causative agent is the amoeba of dysentery.
Symptoms begin to appear 7 to 10 days after infection. These include headaches, general malaise, fever, and some people may have an upset stomach. This is followed by complications, which are expressed in liver problems. If the patient does not start treatment on time and does not go to a specialist, then the consequences will be irreversible.
Toxoplasmosis
The causative agent of the disease is Toxoplasma gondia. Symptoms of this disease include eye damage, the nervous system suffers, and the cardiovascular system. Very often, at first, the infection is extraordinary, as if passing a common cold.
Infection during pregnancy is very dangerous. Even if the child survives, there are very likely to be complications and damage to the eyes or nervous system. Thus, even with the first symptoms, it is necessary to consult a doctor.
Balantidiaza
It is caused by a microorganism such as balantidia. The symptoms of this disease are colic, indigestion. In some cases, a high temperature, intoxication of the body is also possible.
leishmaniasis
Leishmania is considered to be the cause of this disease. With the appearance of skin and mucous membranes, ulcers appear. With mucocutaneous manifestations, edema can often occur. Since these diseases are associated with the respiratory tract, there can be death.
Leishmaniasis is mainly found in hot places. This 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 irreparable damage to the human body, as well as bring certain consequences and complications.
How they are transmitted
There are 4 most common ways of infection:
- Contact - Household. . . This type is manifested due to violation of sanitary measures or rules of hygiene. Infection can occur from a variety of 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, to have your own personal care products and in no case should you use someone else's.
- Fecal - oral. . . This type occurs as a result of contact with stool or vomit. The simplest parasite first enters the hands or food of the "new host", and then into his body.
- From food. . . This type is manifested as a result of eating contaminated foods. This can be poorly cooked fish or meat, unwashed vegetables and fruits, dairy products.
- Transmissible. . . This type occurs as a result of transmission from an infected object during a bite, i. e. through the secretion of saliva.
How to get rid of them
After reading the article, this question certainly arises. Infections with the simplest parasites are very common, so the issue of removing them is extremely important.
As mentioned earlier, when the first symptoms of infection appear, you should consult a doctor. The specialist may prescribe certain tests and examinations. After passing them, the doctor will make an accurate diagnosis. After that, an urgent need to continue treatment. It is also not recommended to treat yourself, because it is a professional who is able to help establish the correct diagnosis and prescribe an appropriate treatment. In most cases, doctors use treatment with various medications that help eliminate parasites and speed up human recovery.
In modern times, there are many different good medicines that help with protozoan parasite infections. There is a huge variety of medicines on the market, which makes it possible to find the right one for a particular patient.
Preventive measures
In order not to face the above problems, it is necessary to adhere to certain rules, as well as take preventive measures.
The most effective rules are those taught by children in school. First of all, you should not forget about thorough washing of fruits and vegetables. You can also heat the treatment or cut the skin.
Moreover, you can not eat raw fish, not fully cooked meat. It is necessary to fully prepare the dish, to respect the temperature regime and time, in order to fully cook the product. Casual sex should be avoided. And you should also undergo regular medical examinations.
