It is necessary to start with the fact that the simplest organisms appeared a long time ago, they are considered to be the oldest inhabitants of the planet. Throughout their existence, they have become incredibly resistant to various tests. They can survive in the most dangerous environment.
These microorganisms have chosen a very suitable way of existence - parasitism, especially in the human body. As mentioned earlier, these microorganisms are incredibly "harmful" and persistent, so they are sometimes so hard to get rid of.
There are several types of "habitats" of parasites. The first type includes endogenous microorganisms, ie those found in the human body. The second type includes exogenous parasites that easily "deposit" on the skin and cause various skin diseases.
Types of protozoan parasites
There are basically 4 types of parasites that "live well" in the human body.
Whiplash
They include lamblia, trypanosomes. This class is a representative of the oldest representatives of parasites. They got this name thanks to their organ of movement: whips. The size of the parasites themselves is simply microscopic, they have a constant shape and reproduce, as a rule, by dividing into two parts.
They are very dangerous to humans and animals, if they enter their body, they cause enormous damage. They also cause various diseases. Such as American carotid fever, cutaneous leishmaniasis and many others. They can parasitize in the intestines, blood and skin. Thus, it negatively affects human health.
Sporozoans
This species of protozoan parasite has a very complex path of development. It is currently known that the class contains approximately 1400 species. All representatives "choose" a parasitic way of life and are extremely dangerous to humans and animals. Reproduction occurs by dividing cells.
Most often, the tissues and organs of a person or animal are chosen as the "residence". This species causes many diseases. For example, such as malaria, toxoplasmosis.
Ciliates
This includes balantidia. There are about 7000 different species. The organs of movement of these parasites are the targets of which there are many.
A characteristic of this type is the presence of two nuclei. They have a constant body and shell shape. Reproduction is usually done by division. This species is no less dangerous to humans and animals than the previous two.
Sarcode
They include dysenteric amoeba. They are the most primitive of all species and classes. There are about 10, 000 different species! They do not have a permanent body shape. It parasitizes on humans and animals.
They usually 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 is constantly trying to fight parasites, but this does not always succeed because of how long he can withstand all the measures.
Why they are dangerous, what diseases they cause
The simplest parasites are indeed 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 significantly harm humans.
Diseases caused by protozoan parasites:
Malaria
Such a disease is characterized by certain differences. Sometimes there is relief, then relief is replaced by worsening 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, most often when medicine develops at a low level.
Amebiasis
Another no less dangerous disease, the consequences of which can also be sad. The cause is amoeba dysentery.
Symptoms begin to appear 7 to 10 days after infection. These include headache, general weakness, fever, and some people may have a stomach upset. 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, the consequences will be irreversible.
Toxoplasmosis
The cause of the disease is Gondia's toxoplasma. Symptoms of this disease include damage to the eye, suffering from the nervous system, as well as the cardiovascular system. In the beginning, the infection is very often unnoticeable, as if the cold is passing.
Infection during pregnancy is very dangerous. Even if the child survives, it is most likely with complications and damage to the eyes or nervous system. So, even at the first symptoms, it is necessary to consult a doctor.
Balantidiase
It is caused by a microorganism such as balantidia. Symptoms of this disease are abdominal pain, indigestion. In some cases, high temperature, intoxication of the body is also possible.
Leishmaniasis
Leishmania is considered to be the cause of this disease. With manifestations on the skin and mucous membranes, ulcers appear. With mucocutaneous manifestation, edema may often occur. Because these diseases are associated with the respiratory tract, there can also be deaths.
Leishmaniasis is mainly found in hot 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, as well as 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 hygiene rules. Infection can occur through various activities: the use of 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 someone else's.
- Feces - orally. . . 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 as a result of eating contaminated food. It 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, or salivation.
How to get rid of them
After reading the article, this question certainly arises. Infections with the simplest parasites are very common, so the question of dealing with them is incredibly relevant.
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, treatment should be started urgently. Self-medication is also not recommended, as it is an expert who can help make the correct diagnosis and prescribe appropriate treatment. In most cases, doctors resort to treatment with various drugs that help remove parasites and speed up people’s recovery.
In modern times, there are many different good medicines that help with protozoan parasite infections. There is a huge variety of drugs on the market, which allows you to find the right one for a particular patient.
Preventive measures
In order not to face the above-mentioned problems, it is necessary to adhere to certain rules, as well as to take preventive measures.
The most effective rules are those taught to children in school. First of all, you must not forget to thoroughly wash fruits and vegetables. You can also heat treat or cut the skin.
Furthermore, you cannot eat raw fish or fully cooked meat. It is necessary to fully prepare the dish, adhere to the temperature regime and time in order for the product to be fully cooked. Casual sex should be avoided. You must also undergo regular medical examinations.
