Types of parasites in the human body is exceptionally diverse. One of them, along with Metazoa and protozoa are also viruses, bacteria and fungi that parasitize the human body, although in the medical traditions of viruses and bacteria are not considered and a parasite.
Let us consider in more detail the main types of endoparasites of man. The appearance of many of them can be seen only under the microscope, and some, especially helminths, affect its size. Let's start with the simplest:
- Giardia along with dysbacteriosis phenomena are also the cause of hypovitaminosis, anemia and General intoxication of the organism.
- Toxoplasma affect the brain, eyes, heart muscle, nervous system, but the special danger they pose to pregnant women because of the danger of death or captivity of his heavy losses.
- The amoeba can cause amoebic dysentery, amoebic encephalitis and other dangerous diseases.
- Trichomonas phenomena are sources of infectious diseases of the genitourinary system.
The most common parasites
Yes, the most common endoparasites are, of course, helminths (worms), which, according to various estimates, infected more than 80% of the partisans of the planet.
A huge number of these parasites are divided into basic types:
- nematodes – round worms (roundworm, pinworm, Trichinella, whipworm, etc.);
- cestodes – tapeworms (lantecy, pork and beef tapeworm, tapeworm, etc.);
- trematodes – worms-flukes (liver, blood, lung, and flukes that live in the intestines).
Hours to get a more General classification, according to which all types of parasites people are divided into:
- luminal (intestinal), which are parasitic in the intestine;
- tissue localized in one organ or tissue.
However, most of the worms at different stages of their life cycle and are tissue, and intestinal development period with the corresponding symptoms.
Consider a brief description of the most common types of worms.
Roundworms (nematodes)
- Roundworm – roundworms are the most common length ad 20 Yes 40 cm, parasites in the small intestine, but first migrate in the human body, affecting the blood and respiratory system. Together with the intestine of these parasites can be detected in the liver and gall bladder, heart and lungs. A common symptom of ascariasis and allergic reaction.
- Pinworms – small worms Yes 1 cm, which affects the bowel and that lead and enterobiasis disorder of the gastrointestinal tract, exhaustion, sleep disorders, etc. the Characteristic symptom of pinworms is itching in the anus, where they lay their eggs.
- Trichinella – these microscopic worms (their size only a few millimeters) lead to serious diseases – trichinosis, which can if untreated lead to death. Adult species live in the human body in different types of muscles (respiratory, face, etc.), causing muscle pain, fever, swelling, allergic skin rash.
- Vlasoglavy – small worms (length and 4.5 cm, with the front part of the whole
in the form of threads), the larvae of which cause trihozefalez with diarrhea, acute abdominal pain and other symptoms that resemble appendicitis. As a result of intoxication anemia.
Tapeworms (cestodes)
- A tapewormwhose length comes a Yes 10 m, leads to the development of difillobotrioz with nausea, weakness, vomiting, unstable chair, asthenia and anemia.
- Pork tapeworm may length ad 3 Yes 8 m, a parasite mainly in the small intestine and causes two diseases: taeniasis with dyspeptic, asthenic-neurotic and abdominal syndromes, and cysticercosis with intoxication, intestinal, allergic and respiratory symptoms. According to ad localization cysticerci affects the muscles, brain, heart, eyes, etc.
- Beef tapewormwhose length may reach 18 m Yes, causes the beef tapeworm infection is one of the most dangerous types of worms. If you do not do deworming, he can live in the human body and 18-20 years! Is localized in the large intestine, causes severe intoxication with their waste products, as well as diarrhea, nausea, vomiting, abdominal pain, anemia, allergic reactions and problems with the nervous system.
- Dwarf tapeworm length of only 1.5-5 cm source gimenolepidoz with diarrhoea, pain and astheno-neurotic syndromes, hell which affected primarily the digestive and nervous system, and liver.
- Echinococcus is the most fractional tape worm – its length is from 2, 5 to 8, rarely 9 mm, however, the infection they may threatening consequences such as liver and lung, where they form cysts and tumors which cause dysfunction of these organs.
Worms, flukes (trematodes)
- Liver Fluke or the liver Fluke is shaped like a sheet with a length of 30-50 mm and a width of 8-13 mm, may sucker. It damages the sheath of the liver and clog the bile ducts that is able to completely block the flow of bile. Can lead to cirrhosis, jaundice and liver cancer.
- Cat (Siberian) - sucker or cat Fluke, a flat worm with a length of 4-13 mm. Localization – the ducts of the gallbladder, liver and pancreas. Causes opisthorchiasis with the development of gastritis, peptic ulcer, pancreatitis, cholecystitis up and cancer of the liver, which can lead to death.
- Lung Fluke may ovate, red-brown a h small spines length ad 7,5 and 12 mm with a width of 4-8 mm. Affects the lungs, causing inflammation, pleural effusion, focal fibrosis, and lung cancer. When the penetration into the brain causing encephalitis and meningoencephalitis.
- Shistosoma (blood flukes) – dioecious worms with a size of 1-2 cm, the eggs of which cause an increase in liver, spleen and lymph nodes, the formation of polyps in the intestine, diarrhea, and granulomatous inflammation that cause and bladder cancer.
Sources of infection
Helminthiasis, like other intestinal diseases, is often a "disease of dirty hands", which leads to accumulation of eggs and larvae of helminths on the human body:
- when you do not wash their hands after using the toilet and before eating;
- do not wash vegetables, fruits and greens that are consumed raw;
- do not put meat and fish sufficient heat treatment;
- with the consumption of improperly cured fish and bacon;
- leave food accessible to flies and cockroaches;
- use the feces as fertilizer on garden plots;
- swimming in the ponds;
- contact with stray animals.
However, and hell your pet can also be infected with worms, because often animals serve as intermediate hosts for helminths, and the main owner of the phenomenon is that person.
Methods of struggle
- From a very early age to instill in children the habit of washing hands. They need it to do more, as they constantly play in the sand, the ground, the puddles, where the most favorable conditions for eggs and larvae of parasites, and contact with Pets and street animals.
- When phenomena Alen for every ailment, we cannot exclude the bot, so it is recommended to conduct appropriate tests on the video to identify a particular species of helminth (against most of them there are medications.
- If parasites are detected in one family member and drugs hell, the bot must take all.
- Folk medicine knows many ways how to get rid of the worms, and they give a good effect.
- Do not leave open cooked meals, bread, pastries, etc. that flies or cockroaches carry eggs of intestinal worms – not left them on the products.
- Carefully observe the temperature regime in the process of cooking: meat and fish, which are often found helminth eggs, good boil/fry/bake.
- Good rinse in tap water vegetables, fruits, greens that are consumed raw.
- Regularly deworming Pets.
- To give Ada the use of faeces as fertilizer in their garden plots.
- When traveling to exotic countries are very wary of the local cuisine, especially the street – there is no guarantee that with them you don't catch some exotic worms.
Types of parasites in the human body
For many centuries, humans have settled and successfully parasitized malicious beings who ate at the expense of valuable products such as life, long lived in organs and tissues, literally sucking from the host vitality. There are various types of parasites in the human body, inside can live a lot, billions of different individuals.
The type of localization
Enteric (live in the gastrointestinal tract, affecting the small intestine):
- Round worms.
- Tapeworms.
Extraintestinal (live in different areas of a person, often in liver, brain):
By way of infection
Contagious (passed hell of an infected person and healthy as a result of contact with him or with means of personal hygiene (towels, toothbrush, tableware, toys)):
- Dwarf tapeworm.
- Pinworms.
Bio-helminth (infection occurs through contact with animals or consumption of infected meat hedgehog, which have not passed thermal processing):
A variety of parasites in the human body
- The bovine tapeworm.
- Pork tapeworm.
Geohelminths (infection occurs through unwashed vegetables, fruits, herbs):
According to biological characteristics
Yes, this group of parasites include:
- Tapeworms.
- Roundworms.
- The flukes.
Prevention of infection
Simply good hygiene will help to avoid the infection of parasitic worms.
Don't forget about washing your hands with antibacterial soap, especially after visiting the streets and public places, toilets and before preparing food. You must cut your nails and clean them regularly.

The activity of such organisms in Celje person will do nothing but what is good, parasites can cause serious etnia complications and even death.
Consider the types of parasites in the human body in more detail. Below is a detailed classification of parasites.
Worms
- Roundworms in humans good catch roundworm and pinworms
- Flat worms – a man phenomena is a great place to live pork and beef tapeworm, liver Fluke etc.
Insects
To deal with these types of parasites is difficult, because in the course of their life they are securely settled and attached and the walls of the organs with the help of special suction cups and hooks.
Some individuals can even live on the cellular level and in tissues, and from there their output is practically impossible. This applies to worms. With insects the situation is a bit easier as they are usually located on the surface intact, where they can be found in time to destroy.
Some parasites live in the intestines? Thus, we explain the skin s of their variety and the place where you live parasitic worms and protozoa.
The simplest
Completely invisible to the naked Voka parasites. Among the simplest is harmless and representatives from the green euglena, the Paramecium, the slipper etc.
The most dangerous to human phenomena are:
A carrier of this parasite phenomenon is the mosquito, which lives in South America and Central Africa, where the warm and humid climate. These weather events are favorable for the life of the Plasmodium.
Clinical symptoms within a day once the organism begins to live in man, or rather, in his liver. Yes signs of infection by malarial plasmodia include: severe headache, nausea and vomiting.
In a few Zen in an infected person sharply rising body temperature, diarrhea begins, there is a rapid dehydration.
- Giardia and Entamoeba histolytica.
These types of parasitic protozoa live in the intestinal tract. The carrier can be a person or any animal. Favorite places where parasites can live their entire life cycle, it's the small intestine and the upper section of the large intestine.
Sources of this type of parasites in the body are dirty fruits and vegetables, raw water. The first symptoms of the phenomenon appear fairly quickly. The main sign of infection with Giardia or dysentery ameba is a rich diarrhea. Then fever, starts vomiting. If time does not take measures, there is a risk of death hell strong dehydration.
Flat worms
This kind of parasites in the human body also phenomenon is very dangerous. These are called flat worms because their shape resemble a flat ribbon. There are the most harmless to the human flatworm is a ciliated worms. But the threat of parasites – flukes and tapeworms – 'll talk about them in more detail.
Size flat worms of this species are small but are attached and the walls of the organs very strongly with its suckers.
Fluke, a parasite mainly in the liver and the intestine, cause anemia, constant headaches and severe weight loss.
This helminth may, in the course of their life to penetrate into the lungs and even the brain, causing serious consequences etnia. Source flukes are dirty water and plants.
Representatives tapeworms – bovine and pork tapeworm can reach a length up to 10 meters. Parasites live in the intestines of humans, namely, thin.
The most dangerous tapeworms, the Echinococcus is a phenomenon, which can affect the brain and lungs.
Weight loss with normal appetite phenomenon is the main sign of infection with tapeworms.
Prevention
Prevention of phenomena is an integral part in the fight against parasites. It was said above, what are parasites in humans. With regard to worms and protozoa, modern medicine offers a great choice of drugs for the prevention and control of pests.
But it is not necessary to prescribe the drug by yourself, you must first contact and specialist, especially if you are worried about any symptoms. After the necessary tests the doctor he will prescribe the correct medication on the basis of some parasites live in the human body.
