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. Throughout 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 have chosen a very convenient form of existence for themselves: parasitism, particularly in the human body. As mentioned above, these microorganisms are incredibly "harmful" and persistent, making them very difficult to get rid of sometimes.
There are several types of "residence" for parasites. The first type includes endogenous microorganisms, that is, those found within 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 a representative of the oldest representatives of parasites. They received this name thanks to their organ of movement: the flagella. 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 your body, they cause enormous damage. They also cause various diseases. Like American carotid fever, cutaneous leishmaniasis, and many others. They can parasitize in the intestines, in the blood and on the skin. Therefore, it negatively affects human health.
Sporozoa
This type of protozoan parasite has a very complex development path. The class is currently known to contain approximately 1, 400 species. All representatives "choose" a parasitic life form and are extremely dangerous to humans and animals. Reproduction occurs by cell division.
Very often, the tissues and organs of a person or an animal are chosen as the "place of residence". This species causes many diseases. For example, like malaria, toxoplasmosis.
Ciliates
These include balantidia. There are around 7000 different species. The organs of movement of these parasites are the cilia, of which there are many.
One such feature is the presence of two nuclei. They have a constant body shape and shell. Reproduction is usually done by division. This species is no less dangerous to humans and animals than the previous two.
Sarcode
These include amoeba dysentery. They are the most primitive of all types and classes. There are around 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. Due to them, a person can suffer a 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 parasites, but it does not always work because of how much they can withstand all the measures.
Why are they dangerous, what diseases do they cause?
The simplest parasites are in fact very dangerous to human health. They can cause various diseases that carry certain consequences. In no case 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, seizures.
For many years, chitin has been considered the best treatment. However, there are also deaths from this disease more often when the medicine is developed at a low level.
Amoebiasis
Another no less dangerous disease, the consequences of which can also be sad. The causative agent is amoeba dysentery.
Symptoms begin to appear 7 to 10 days after infection. These include headache, 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, the consequences will be irreversible.
Toxoplasmosis
The causative agent of the disease is Toxoplasma de Gondia. Symptoms of this disease include eye damage, the nervous system suffers, as well as the cardiovascular system. Very often, at first, the infection is not noticeable, as if you had a common cold.
Infection during pregnancy is very dangerous. Even if the child survives, he or she will most likely have complications and damage to the eyes or nervous system. Therefore, even with the first symptoms, it is imperative to consult a doctor.
Balantidiasis
It is caused by a microorganism such as balantidia. The symptoms of this disease are abdominal pain, indigestion. In some cases, a high temperature is also possible, intoxication of the body.
Leishmaniasis
Leishmania is considered the causative agent of this disease. With cutaneous and mucocutaneous manifestations, ulcers appear. With the mucocutaneous manifestation, edema can often occur. Since these diseases are associated with the respiratory tract, there can be deaths.
Leishmaniasis is found mainly 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, in addition to having certain consequences and complications.
How they are transmitted
There are 4 most common forms of infection:
- Contact - home. . . This type manifests itself due to violation of sanitary measures or hygiene rules. Infection can occur from 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 use someone else's.
- Fecal - oral. . . This type occurs as a result of contact with feces or vomit. The simplest parasite first enters the hands or food of the "new host" and then its body.
- Of the food. . . This type manifests itself as a result of eating contaminated food. It can be undercooked fish or meat, unwashed vegetables and fruits, dairy products.
- Transmissible. . . This type occurs as a result of 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, this question certainly arises. Infections with the simplest parasites are very common, so the question of getting rid of them is incredibly relevant.
As mentioned above, 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 proceed to treatment. It is also not recommended to self-medicate, because 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 drugs that help eliminate parasites and accelerate human recovery.
In modern times, there are many different good medications that help with protozoan parasite infections. There is a wide variety of medications on the market, allowing you to find the right one for a particular patient.
Preventive measures
In order not to cope with the above problems, it is imperative to adhere to certain rules, as well as to take preventive measures.
The most effective rules are those taught by children in school. First of all, you should not forget about the thorough washing of fruits and vegetables. You can also perform a heat treatment or cut the skin.
Also, you cannot eat raw fish, not fully cooked meat. It is imperative to fully prepare the dish, observe the temperature regime and time to fully cook the product. Casual sex should be avoided. And you also need to undergo periodic medical examinations.
