It is necessary to start with the fact that the simplest organisms appeared long ago, are considered the oldest inhabitants of the planet. Throughout 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 way of being for themselves - parasitism, especially in the human body. As mentioned earlier, these microorganisms are incredibly "harmful" and persistent, so sometimes it is so difficult to get rid of them.
There are several types of "home" pests. The first type includes endogenous microorganisms, ie those found in 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.
Flog
These include lamps, drill bits. This class is representative of the most ancient representatives of parasites. They got this name thanks to their locomotor system: flagella. The size of the parasites themselves is simply tiny, they have a fixed shape and they 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, skin leishmaniasis and more. They can infect the intestines, blood and skin. Thus, it adversely affects human health.
Sporozoans
This type of protozoan parasite has a very complex developmental path. The order is known to contain about 1400 species. All representatives "choose" a parasitic lifestyle and are extremely dangerous to humans and animals. Reproduction is by cell division.
Most often, the tissues and organs of a person or animal are selected as the "habitat". This species causes many diseases. For example, such as malaria, toxoplasmosis.
Tsilites
These include balantidia. There are about 7000 different species. The motor organs of these parasites are eyelashes, of which there are many.
A feature of this type is the presence of two nuclei. They have a stable 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 about 10, 000 different species! They do not have a permanent body shape. Parasites in humans and animals.
Most of the time, they choose the digestive system for their activities. Because of these, a person can experience very serious poisoning. In some cases, deaths are also common.
These types combine high strength in various "tests". After all, an infected person is constantly trying to fight the parasites, but it does not always work because of how much it can withstand all measures.
Because 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. 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, some 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 was considered the best treatment. However, there are also deaths from this disease more often when the drug is underdeveloped.
Vulnerability
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 headache, general malaise, fever and some people may have stomach aches. 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 gondii. Symptoms of this disease include damage to the eyes, nervous system, and cardiovascular system. Very often, in the beginning, the infection is noticeable, as if passing a common cold.
Infection during pregnancy is very dangerous. Even if the child survives, it is more likely to have complications and damage to the eyes or nervous system. Thus, even with the first symptoms, it is imperative to consult a doctor.
Ballantiasis
It is caused by a microorganism such as balantidia. The symptoms of this disease are abdominal pain, indigestion. In some cases, it is also possible to poison the body at a high temperature.
Leishmaniasis
Leishmania is considered to be the causative agent of this disease. With skin and mucous membrane manifestations, ulcers appear. With mucosal manifestations, swelling can often occur. Since these diseases are related to the respiratory tract, there may be deaths.
Leishmaniasis occurs 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, as well as certain consequences and complications.
How they are transmitted
There are 4 most common ways of infection:
- Communication - household. . . This type is manifested due to violation of sanitary measures or rules of hygiene. Infection can result from various activities: the use of other people's objects, 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.
- Stool - oral. . . This type occurs as a result of contact with feces or vomit. The simplest parasite enters first the hands or food of the "new host" and then its body.
- From food. . . This type is manifested as a result of consuming contaminated food. 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 definitely arises. Infections with the simplest parasites are very common, so the issue of getting rid of them is extremely important.
As mentioned earlier, when the first symptoms of infection appear, you should consult a doctor. The specialist may prescribe some tests and examinations. After passing them, the doctor will make an accurate diagnosis. After that, an urgent need to proceed with treatment. Also, self-medication is not recommended, because it is a professional who can help in the correct diagnosis and prescribe appropriate treatment. In most cases, doctors resort to treatment with various drugs that help eliminate parasites and speed up the human recovery.
In modern times, there are many different good medicines that help with protozoan infections. There is a huge variety of drugs on the market, which makes it possible to find the right one for a particular patient.
Precautionary measures
In order not to face the above problems, it is imperative to follow certain rules, as well as to take precautionary measures.
The most effective rules are those taught by children in school. First of all, you should not forget the proper washing of fruits and vegetables. You can also heat the treatment or cut the skin.
In addition, you can not eat raw fish, not fully cooked meat. It is imperative to fully prepare the dish, adhere to the temperature and temperature time, to fully cook the product. Casual sex should be avoided. And you should also undergo regular medical examinations.
