Human parasites are called all bodies that live at its expense. These are bacteria, mushrooms, worms. Human parasites are divided into internal and external. The most unpleasant and causing the greatest number of body destruction are the Elmininti: a variety of parasitic worms.
Parasites and human body
The creatures that parasites to the human body can be external or internal. The exterior includes:
- Mosquitoes.
- Leeches.
- Lice.
- Microorganisms that cause scabies.
But there are many more creatures who prefer to settle inside the body. These include:
- Bacteria.
- Correct.
- Elmininti.
- Fungal.
The external and internal organization of the parasite belongs to the simplest. Due to the fact that they do not need to evolve for survival reasons, their organization is very simplified.
There are many creatures that prefer to settle inside the body. For example, they can be bacteria.
They cannot survive without the guest body, unable to get their own food. But they all reproduce, almost without exception, very quickly, especially in the conditions suitable for this. Where they were not immediately thrown.
They differ territory. Some can be found everywhere, no climate for them is an obstacle. Others live exclusively in tropical countries, but on the human body they can be easily brought to all the others. In the body, they also settle in different places.
Even the cycles of the development of parasites, mainly helminths are different. Some initially develop in the ground (Biohelminths) and then move to a living creature. Others must first develop in the body of any other living creature, but not a person. Third, in an adult state, you can move to another or to you to make up.
It is wrong on assuming that the infection can occur exclusively through the dirty hands. The eggs of some helminths are vital outside the nutritional medium for six months and cling perfectly to animal wool. The eggs survive in a dangerous environment for them: it is worth cooking meat or fish incorrectly, while an entire niduch of worms can be paid inside you.
It is worth cooking the meat incorrectly, as an entire brood of worms can be paid inside you.
Endoparasititis of a person
Parasites are divided into endoparasites and ectoparasites. Endoparasiti - Those who settle inside, ecto - outside. Endopagases are able to settle in almost all internal organs and body tissues. They are divided according to the location. Endopagases are:
- Connection to the external environment of the endoparasites of the internal organs.
They settled precisely in those organs connected to the external environment, not vice versa: the parasitic body is not chosen to "breathe". These organs include the intestine, light and human urine system. These are Amebe, worms and parasites on fire.
- Parasites.
Set in human blood. They can live in plasma, white blood cells, red blood cells. These are tripanosomes, microfilaria or emosporids.
- Endopaarasiti in fabric.
The endopagases who choose the body's tissues with their place of residence. Muscle tissue, brain, cartilage, connective tissue. Even in nerve fibers, tissue endoparasites can be established. These are strips fins with stripes, tripanosomes, mixosporids, trichin and others.
Endoparasites can choose the brain with their place of residence.
The determination of the variety of the parasite in the place of its location is very conditional. Many species are able to migrate in various internal organs, regularly traveled the owner's body. The propagation process can occur in one place and the bodies will be directly and will feed another. The place where the parasite is justified and will be considered the place of its conditional location.
Despite the simplification of many parasites systems, their life cycle is quite complicated.
Some varieties throughout their lives for survival must change several owners who can relate to different biological species. Others are able to survive only a biological species inside, but can request intermediate guests. In one person they multiply and they develop and grow in another. With such a complex life cycle, their sexual functions have significantly increased. It is necessary to multiply by survival in the parasites of the body quickly and a lot.
Helminths
There are three main varieties of helminths, also called worms. This:
- Nematodes, are round worms.
- Cestodes, endoparasititis of the ribbon shape.
- Trematato, also known as saucers.
Subsequently, they can be divided by the life cycle and the number of positions that travel this path. There are also three types:
Geo-Shelminths.
"GE" is the earth. These worms begin their existence in earthly soil, only after the maturation phase can they infect a person. They do not need intermediate guests, eggs fall to the ground together with the human feces. On the larval stage, they develop exclusively in the hot season.
These worms include Ascarides, intestinal ugrititsy, a non -core and blazo -heads.
The larvae of these parasites can enter the human body through untreated vegetables or direct contacts with the ground.
Biohelminths.
These are parasitic worms, whose phases of life pass through several owners. Intermediate guests can be two or more depending on the variety of worms. Some parasites only change a person. Others, before finally entering the human body, are used by organisms of other biological creatures for development.
You can infect through pets or in contact with other people, even when consuming dry meat. Biohelminths include Tani Tori, Echinococcus, wide ribbon, trichin and others.
Elmininti di Contagio.
These worms do not need land or intermediate owners. All the phases of their life cycle pass in an organism, in a very comfortably position. The larvae are distinguished directly from the human body, when contacting domestic surfaces and other people, spreading freely.
Elminants can live in different organs and systems of the human body, periodically migrating from one part of the body to the other.
The list of diseases caused by Elmininti is very extensive. Determine what parasites live in the body and which treatment can only be started after all the necessary analyzes are passed to establish the type.
Round worms
The most widespread in the human environment were the round worms, also known as nematodes. In total, there are more than 24 thousand types of nematodes in the world.
They are round due to their shape, which is detected if a transversal cut is made. The most common human nematodes:
- Askarids.
- Speakers.
- Trichina.
- Blacovyv.
The Elmintic Invasion, known as Ascariasis, begins with direct contact with the larvae infected from the ground or when using untreated fruit and vegetables. Parasites begin to develop in the intestine, then enter the circulatory system of a person, from where they go to several internal organs, heading to the oral cavity. A person does not notice it, repeatedly swallows an adult parasite. They feed the remains of unlawful food. Ascaris waste is extremely toxic. There is no vaccine from ascariasis, the infection can be prevented exclusively by observing the rules of personal hygiene.
Pinworms infection is called enterobiasis. These are small worms (5-10 mm) attached to the walls of the intestine. They feed on blood and content of the intestine. They put their eggs under the skin, leaving the anal opening outside while the owner sleeps. Due to the itching, a person with a comb, the anal region, the larvae fall under the skin and hands, can be easily transferred to other people at home or in public places. The entepiosis has no painful symptoms, detecting the Pinworms infection in the initial phase is extremely problematic.
Trichinella, they are Trichina, these are round worms who choose an animal or a person with their master.
Tricinella is a parasitic worm that affects the human body, causing a dangerous tricinellosis vermis disease.
They begin to develop in the area of the muscles crossed in the body, then redirect to the small intestine. In advanced cases of infection per kilogram of muscle tissue, around 15 thousand trichinella eggs can be found. These parasites can cause a fatal disease, which takes its name from its source - Tricinellosis.
The round worms of the Blazovians are so called for their appearance. The front of their body is a filament, it contains an esophagus.
The rear is wider, the remaining internal organs of the parasite are inside. The length of the blazoli can reach 50 mm. It feeds on blood and tissue fluid. It causes trichocephaly disease.
Tape worms
In the world there are about 3. 500 species of famous stripes worms, whose type is also called Cestades. There are no digestive systems at all in these dishes and diseases they cause are called to bask.
The most common cestodoxis:
Cististirkosi.
The disease of the pork tension larvae is excited, entering the polluted food, with dirty hands.
The disease affects the skin, bones, internal organs, brain and spinal brain. Very often, parasites are sent to the brain (in 60% of cases of infection). It is diagnosed based on the appearance of rounded formations on the skin. The disease is treated, in case of central nervous system infection, the forecasts can be unfavorable.
Echinococcosi.
Located in the liver, in the lungs, many other internal organs. Echinococcus larvae excites the disease. They can develop within a person for several years.
The infection occurs in contact with animals, which collect berries and fruits, consumption of contaminated water. The disease is not too evident, it can develop for years and is revealed only by chance.
Alveococoscosi.
Alveococosis is caused by alveocococcus worms. The disease is similar tochinococcosi, but proceeds more seriously. It affects the lungs and kidneys. Without the treatment of the disease, there is a great probability of fatal outcome in relation to the development of liver insufficiency.
Toniario.
Tusiarinchosis is caused by a bull chain. Parasitizes Tenia in the small intestine area, it develops for 2, 5-4 months. Forecasts are more often in favor of treatment. Parasites can enter a person with infected or sufficiently treated raw meat.
Ribbon worms are very fertile. They have reduced the rest of the sensitivity and there is no digestive system at all. These parasites are unable to develop without the owner.
Workers of Sosal
Supreme is Tremontades. These are flat worms, in the shape of a body that recalls an oblong leaf of a tree.
Some types of Trematodes can reach the size of one and a half.
And they are found in the human body, they are often through fish or other seafood. About 7200 types of Trematodes are known, 40 of them are deposited in people and cause trembling, serious diseases caused by the infection.
The most common wages:
The liver bicom.
Globally, it can exist in animals and people. The biological life cycle is complex, the parasite changes the owners.
Schistosoma.
The desk larvae can penetrate the skin or mucous membrane. The life cycle is complex, it feeds on blood. A female is able to produce about 3. 000 eggs per day, the fertility of these parasitic worms is very high.
Other liver balmers.
Opistorchiesi, Helminth's disease, which spreads mainly in the liver area. The human body has a toxic effect.
The digestive system of Wormworms is well developed and with It-Sessual and excretory. The rest of the systems develops badly. The Tremontodes feed on blood, epithelial cells of the skin, the content of the intestine. They can live almost everywhere: from the liver to the conjunctival eyes of the eyes.
Other types of endoparasiti
The remaining internal parasites are a variety of bacteria that cause dangerous diseases and with them the simplest microorganisms. The fungus that spreads within the human body also refers to the endoparasite section.
Many useful and harmful microorganisms live in the human body. Some of them cause fairly dangerous diseases that can lead to death. It is not always possible to immediately recognize the presence of parasitic creatures within you, but the early diagnosis of infection gives more possibilities to complete the cure. If the invasion is suspected, it is recommended to quickly undergo a complete exam by a doctor.
