Human parasites are called all organisms that live at its own expense. These are bacteria, fungi, worms. Human parasites are divided into internally and externally. The most unpleasant and causing the largest number of destruction of the body is helminth - a variety of parasitic worms.Parasites and human body
The creatures that penetrate the human body can be externally or internally. The outside includes:Mosquitoes.Leeches.Lice.The microorganisms that cause scabies.
But there are many more creatures that prefer to settle in the body. These include:Bacteria.Suitable.Helminths.Fungus.
The external and internal organization of the parasite belongs to the simplest. Due to the fact that they do not need to evolve for the sake of survival, their organization is very simplified.There are many creatures that prefer to settle in the body. For example, it can be bacteria.They cannot survive without the host body, unable to get their own food. But everyone is bred, almost without exception, very quickly, especially in the conditions that are suitable for it. Where they are not driven from immediately.They differ territorial. Some can be found everywhere, no climate for them is an obstacle. Others live exclusively in tropical countries, but in the human body they can easily be transported to anyone else. In the body, they are also installed in different parts.The circles of pest development, especially the helm, are also different. Some initially grow on the ground (BioHelminths), and then move to a living creature. Others must first grow on the body of any other living creature, but not in a person. Thirdly, in an adult state, you can transfer to another or restore yourself. It is wrong to assume that infection can occur exclusively through dirty hands. The eggs of some helmets are viable outside the nutrient for six months and adhered perfectly to wool. Eggs survive in a dangerous environment for them - it's worth cooking meat or fish incorrectly, as a set of worms can be paid within you.It is worth cooking the meat incorrectly, how a whole worm stairs can be paid within you.Intravenies of a person
The parasites are divided into endoparasites and ecopesites. Endoparasites - those installed in, ecto - out. Endoparasites are able to install on almost all internal organs and tissues of the body. They are separated according to the detection. The endoparasites are:Connecting to the external environment of the endoparasitic internal organs.
They were accurately installed in those organs associated with the external environment, not the other way around: the parasitic body has not been selected to "breathe". Such organs include intestines, light, human urine system. These are amoebas, worms and parasitic burning.Parasites.
Placed in human blood. They can live in plasma, white blood cells, red blood cells. These are Tripanosomes, Microfilariae or Haemosporidia.Intraoperative fabrics.
These endoparasites who choose body tissues with their place of residence. Muscle tissue, brain, cartilage, connective. Even in nerve fibers, endoparasites can be installed. These are the wings of the worm, the triggers, the myxosporitis, the trichina and others. Endoparasites can choose the brain with their place of residence.Determination of the variety of the parasite in place of its location is very conditional. Many species are able to migrate to various internal organs, travel regularly to the owner's body. The propagation process can occur in one place and the organizations will be immediately and will feed another. The place where the parasite is justified and will be considered the place of its conditional identification.Despite the simplification of many pest systems, their life cycle is quite complicated.Some varieties throughout their life for survival must be changed by several owners who may be related to different biological species. Others are able to survive only one biological species inside, but they may require intermediate hosts. In one person, they multiply, and in another grow and grow. With such a complex life cycle, their sexual functions increase significantly. It is necessary to multiply for survival in body parasites quickly and much.Helminth
There are three main varieties of helm, also called worms. This:Nematodes, they are round worms.CESTODES, film -shaped intra -film.Trematodes, also known as saucers.
They can then be separated from the life cycle and the number of positions passing along this path. There are also three types:GEO-SHELMINTHS."Ge" is the earth. These worms begin their existence on the earth, only after the ripening stage can a person contaminate. They do not need intermediate hosts, eggs fall to the ground with human faeces. At the larvae stage, they grow exclusively in the warm season. Such worms include Ascarides, intestinal ugitsy, non -core, and blazo -heads.The larvae of these pests can enter the human body through unwashed vegetables or direct contact with the soil.BioHelminths.These are parasitic worms whose stages of life go through various owners. Intermediate hosts can be two or more depending on the variety of worms. Some parasites change exclusively one person. Others, before they eventually enter the human body, are used by organisms of other biological creatures for growth.You can be infected through pets or in contact with other people, also when consuming half dried meat. Biochellinths include bulls, echinococcus, wide film, Trichina and more.Helminths Contagioine.These worms do not need any ground or intermediate owners. They go through all stages of their life cycle in an organism, very comfortably positioned. The larvae stand out directly from the human body when they come into contact with the surfaces of households and other people, spreading freely.Helminants can live in different organs and systems of the human body, which periodically migrate from one part of the body to another.The list of diseases caused by helminths is very extensive. Determine which parasites live in the body and what treatment can only start after all the analyzes required to establish the type. Round wormsThe most widespread in the human environment was round worms, also known as nematodes. Overall, there are more than 24 thousand filamentous types in the world.They are round because of their shape, which is detected if you make a transverse cut. The most common human nematodes:Askarids.Speakers.Trichina.Blacovyv.
The helminth invasion, known as Askaria, begins with direct contact with the larvae that are contaminated by the ground or when using laundry fruits and vegetables. Pests begin to grow in the intestines, then enter a person's circulatory system, from which they go to different internal organs, head to the oral cavity. A person who does not observe this repeatedly swallows an adult parasite. They feed on the ruins of indefinite food. The waste of Ascaris is extremely toxic. There is no vaccine from Askaria, infection can be avoided exclusively by observing the rules of personal hygiene.Pinworms infection is called Enterobiasis. These are small worms (5-10 mm) associated with bowel walls. They feed on blood and bowel contents. They put their eggs under the skin, come out of the anal opening out, while the owner sleeps. Due to the itching, a person combs the anal area, the larvae fall under the skin and hands, they can easily be transported to other people at home or in public places. ENOVATION has no painful symptoms, the detection of Pinworms infection at the initial stage is extremely problematic.Trichinella, they are Trichina, these are round worms who choose an animal or person with their master. Trichinella is a parasitic worm that affects the human body, causing a hazardous vermis disease of trichinel.They begin to grow in the area of intersecting muscles in the body and then redirect to the small intestine. In advanced cases of infection per kilogram of muscle tissue, about 15, 000 trichinella eggs can be detected. These pests can cause a deadly disease, its name from its source - trilogy.The Blazovians' round worms are so called because of their appearance. The front of their body is a thread, contains an esophagus.The back is wider, the other internal organs of the parasite are found in it. The length of Blazoles can reach 50 mm. It supplies with blood as well as tissue liquid. Causes hair head disease.RibbonThere are about 3. 500 species of famous strips worms, the type of which is also called Cestodes. There are no digestive systems in these levels of worms at all, and the diseases they cause are called CESTODOSIS.The most common cesteodossis:Cyst.The disease of pork larvae is excited, entering in polluted foods, of dirty hands.The disease affects the skin, bones, internal organs, brain and spinal brain. Most of the time, parasites are sent to the brain (60% of cases of infection). It was diagnosed on the basis of the appearance of rounded formations on the skin. The disease is treated, in the event of infection of the central nervous system, the predictions can be adverse. Echinococcosis.Mounted to the liver, lungs, many other internal organs. Echinococcus larvae stimulate the disease. They can grow within a person for several years.Infection occurs in contact with animals, the collection of berries and fruits, consumption of contaminated water. The disease is not very noticeable, it can grow for years and is only revealed by accident.Cell.The cell is caused by cell worms. The disease is similar to echinococcalism, but it progresses more serious. It affects lungs and kidneys. Without the treatment of the disease, there is a high probability of a deadly effect on the development of liver failure.Tangible.Tusiarinchosis is caused by a chain of bulls. Parashes the film in the area of the small intestine, develops for 2, 5-4 months. Forecasts are more often favorable to treatment. Pests can be put into a person with infected raw or inadequately processed thermal meats.Ribbon worms are very fertile. They have the most reduced the rest of the sensitivity and there is no digestive system. These pests are not able to grow without the owner.Workers SosalSupreme is tremontodes. These are flat worms, in the form of your body that resemble an elongated leaf of a tree.Some types of trematodes can reach one and a half meters in size.And they are in the human body, more often through fish or other seafood. About 7200 types of trematodes are known, 40 of which are settled in humans and cause trembling, severe diseases caused by infection. The most common salads:The liver bicom.Worldwide, it can be in animals and humans. The biological life cycle is complex, the parasite changes the owners.Schistosoma.Schistosome larvae can penetrate the skin or mucosa. The life cycle is complex, it feeds the blood. A female is able to produce about 3. 000 eggs a day, the fertility of these parasitic worms is very high.Other Balemers liver.Opisthorchiasis, Helminth disease, which spreads mainly to the liver area. The human body has a toxic effect.The digestive system of worms is well developed, with self-sexual and secretory. The rest of the systems are badly developed. Tremontodes feed the blood, epithelial cells of the skin, intestinal contents. They can live almost anywhere: from the liver to the eyes of the eyes.Other types of endoparasitesThe rest of the inner parasites are a variety of bacteria that cause dangerous diseases and with the simplest microorganisms. The fungus that spreads into the human body also refers to the part of the endoparasites.Many useful and harmful microorganisms live in the human body. Some of them cause quite dangerous diseases that can lead to death. It is not always possible to recognize the presence of parasitic creatures in yourself immediately, but the early diagnosis of infection gives more chance of completing treatment. If an invasion of invasion, it is recommended to quickly undergo a full examination by a doctor.
