Types of parasites

Opisthorchiasis - a disease of the group of helminth infection, damage the liver and the pancreas. In the world there are about 21 million people infected with the liver trematodes. The giardiasis. Widespread protozoan disease, during which you can vary from a subclinical to a severe form and occurs due to the infection. The disease of the worms, caused by the pork tapeworm. The disease of the group of helminth infection, damage the liver and the pancreas.

Types of parasites

Only people with qualifying medical know all the types of parasites in the human body. The greater part of them do not represent any risk to health. Despite this, long-term of some diseases can cause serious complications.

The parasites on the body of adults and children

Not everyone knows what are the parasites and where they live. Of this disease suffer people of all ages. The human parasites are the following bodies:

• the fungus of yeast);
• helminths (nematodes, cestodes, trematodes);
• protozoa (unicellular organisms);
• ticks;
• the louse of the head;
• bed bugs;
• the larvae of various insects.

All the distinguished property: they lead parasitic life-style, that is to say, they feed and grow at the expense of the person. Your life is different from the duration. Some parasites can exist in the body of the people from 20 to 30 years, without cause of your specific clinical picture. There is a classification of the parasites according to their habitats. More often surprised the epidermis of a person. These organisms are called ectoparasites. Them concern, bed bugs, lice, many fungi and mites. The data of the creatures can live in the interior of the organs, the lymph vessels and muscles. They represent a great risk due to the possibility of soft tissue injury.

Varieties of parasites in function of the location of

Some worms live in the liver. These include fluke, Fasciola Hepatica, Echinococcus, ascaride, toxocariasis. There are types of worms that live in the lungs. In this group are included ascaride, Echinococcus, the representatives of the nematode pathogens paragonimoz. Some helminths can be found in the bile ducts (the fluke feline, Fasciola Hepatica). Sometimes, in the process will involve the muscles. Occurs when the infection of trichinosis. Less frequent involvement of the kidneys and urinary track. The parasites that are living in these bodies are to schistosoma. Often helminths present in the blood and the lymph vessels. The parasites mainly affect the skin of the water. It is possible to participate in the process of the mucous membranes. The most common diseases such as scabies, head pendant, and pubic lice, yeast infection. Lice feed on the blood of the people, causing itching. They are here on the scalp, the pubic area and in the inner layer of the clothing that fits your body.

As the parasites penetrate the human body?

It is necessary to know not only the information on what types of parasites that are found here close to the people, but and how to make the contagion. Often, the person acquires an imperceptible way. What happens in the home, or in the conduct of professional activities, when working on a plot of land, the contact with domestic animals (cats, dogs, rodents). The development of the intestinal parasites occurs when ingested eggs or larvae of helminths through the mouth. This occurs when the consumption of contaminated products, infected meat or fish, as well as through dirty hands. People become infected primarily through fecal-oral mechanism. Less frequently gathers data transfer contact, when the parasites are introduced into the skin. This is possible the itching, the piojose, mycosis, the strongyloidiasis, hookworm.

The parasites are transmitted by food (meat, fish, vegetables, fruits, herbs, berries), water, dirty hands of the earth. There are helminths and protozoa, which enter the body of the person when entering in contact with contaminated with the feces of the animals wool. Some parasites of the worms in the form of eggs and protozoa are microorganisms that are transmitted through insects and mites. Vectors can be mosquitoes, mosquitoes, flies. Separately distinguished from the parasites which can be transmitted during sexual relations. This group includes trichomonas, fungi, pubic lice. The great value which they have loved, which penetrate from one person to another directly through the skin and are able to live in the man for a long time. This results in the spread of the disease caused by dwarf tapeworm, that lives in the small intestine of man.

Representatives of a group of ectoparasites

Not only need to know the types of dangerous creatures, but and then, what of them is able to dwell in the skin of the person. It is very common in this type of disease, such as lice. He is the head, and a pubic. The causative agent of — the louse. These parasites affect the skin of the facies and its appendages (the hair). Head lice are most frequently detected in childhood. Of the cause, and in close contact with other children, the breach of the rules of hygiene and the overcrowding of the collective". Head lice have the following distinctive characteristics:

• they are ectoparasites (living on the surface of the body of the person);
• they feed on the blood;
• cause a strong itching on the skin;
• the value of 0.4 to 6 mm;
• they live about a month;
• have a high fertility, contribute;
• are sensitive to high temperatures;
• they have piercing-unborn sucking mouth.

During the examination of the sick often identify the eggs of lice (nits). Are too attached to the hair and are of small dimensions. The symptoms of the piojosy more frequently detected in children in age from 15 to 24 years of age. Pubic lice in a greater extent affect the young people. We identify the following risk factors of infection the piojosom:

• the stay in kindergartens, boarding schools and residential homes;
• bad socio-living conditions;
• the presence in the family of the sick;
• the work in kindergartens;
• the third-party use of the clothing;
• visit public places (saunas, baths, beauty salons);
• rare washing of the clothes.

Often you find here the parasites in the human body, as itching of the ticks. They are passed easily from healthy patient to the contact. In the group of risk includes people who enjoy a bed and other personal hygiene items. The itch mites have crack oral appliance. They live under the skin, feed on the epidermis. These parasites cause allergic reactions and skin rashes. Often surprised the skin of the belly, the chest, the hips and the spaces between the fingers. The beings most active during the night, therefore, the symptoms of the disease (itchy skin) are usually expressed in the afternoon and at night.

Worms in the intestine of the human

Not everyone knows species of worms. Are divided into nematodes (roundworms), cestodes (tapeworms) and trematodes (flukes). Many helminths live in the human intestine. Prominent representative of this group of endoparasites is Ascaris. These worms live in the small intestine. The larvae may reach other organs (liver, lungs). The morbidity rate in the world reaches the 85 cases for every 100 thousand people. Most often suffer the little children. The parasites in the form of eggs fall in the bowel when consumption is not sufficient to be washed products. Ascaride have the following characteristics:

• they have round body length scale of up to 40 cm;
• refer to the geohelminths (partially develop in the environment);
• postpone up to 240 thousand eggs per day.

The sick person along with the feces assigns a large number of eggs. Put in the external environment and a time there mature. The presence of this worm in the body can result in inflammation of the gut mucosa and the development of the obstruction. In the group of intestinal helminths enters helminths of a group nematosis caused by worms of the family of worms. Pathogens are ostritsy. These parasites live in the small intestine and in the colon, often leading to overgrowth, enteritis. Ostritsy are small (under 1 cm) worms color white. They have a pointed end, by which they attach to the mucosa. Live data helminths up to 2 months. In the risk group are organized for the children attending children of the gardens and the children, the most important classes of the school. The infection occurs violence in the home or of the food of the way. The transfer factors, are hands, toys, kitchen utensils, products, writing utensils. The parasite has the ability to bring us out of ourselves to the outside to lay their eggs. This happens mainly during the night. The main signs of the presence of worms in the body are: abdominal pain, violation of the chair and the itching in the anal area.

Protozoa human parasites

Only the doctors know the types of parasitism more simple. Their great number. The following are the most common single-celled:

• amoebas;
• balantidia;
• trichomonas;
• Leishmania;
• Cryptosporidium;
• giardia;
• malarial Plasmodium;
• Toxoplasma;
• the trypanosome.

Between protozoosis of the most commonly used for giardiasis. It is a disease caused by single-celled organisms, by far, the defeat of 12 of the duodenum and the liver. The causative agent of the disease — erythrocytes. The human parasites of this type have the following characteristics:

• are single-celled mikroorganizmi;
• live in 2 forms (vegetative and spore);
• are transmitted through food, water, cooking utensils and articles for the home;
• are transferred to the insect;
• mainly affecting children under the age of 10 years;
• the magnitude of up to 21 µm (vegetative forms);
• have flagella (vegetative forms);
• are able to actively move.

These beings are very resistant in the environment. Human infection occurs water, digestive or at a distance and the ways. People are infected cysts giardia lamblia. The peak incidence is observed in the season of spring-summer. Giardia is widespread. In the risk group are the children who attend collective " organized. Often suffer from people who are not trained in simple skills for personal hygiene. Often, when the survey of the patients revealed a micro-organism, such as amoeba. It is a type of the simplest. Beings affect the bowel and can contribute to the formation of abscesses in other organs (liver). These parasites were more often detected in individuals that irregularly wash their hands. Amoeba, living in the form of the trophozoites and the cyst. The past resistant in the environment. In the group of risk of amebiasis includes people with immunodeficiencies, as well as pregnant women. In addition to the amoebas and giardia lamblia in man can be revealed of Cryptosporidium oocysts. It is the germ parasitic in the intestine. Cryptosporidium can cause diarrhea and other intestinal symptoms. Between dangerous for the people of parasites are malaria Plasmodium. Mosquitoes. The infection occurs by the bite of insects.

The clinical manifestations of the presence of parasites

After meeting with the information on what are the parasites live in the intestine, you must know, and the main symptoms of the diseases caused by them. The presence in the body of earthworms is characterized by a disorder of the chair by the type of diarrhea, flatulence, pain in the lower part of the abdomen, itching sensation in the perianal region, irritability, a rash, a violation of appetite. Children with enterobiasis are sick. Ostritsy can be the cause of the development of gastroduodenitis, enteritis and disbakterioza. If in the body there is ascaride, then the people upset nausea, abdominal pain, anal itching, increased production of saliva, decreased appetite, weakness. Simple of ascariasis may be a cause of intestinal obstruction in adult parasites. In the migration phase of the larvae of the possible appearance of the rash and the cough. Allergic reactions and stomach upset are the main symptoms of intestinal helminths. Some worms affecting the muscles. Bright representatives are Trichinella. Cause muscle aches, allergic reactions and swelling. These human parasites, such as flukes, affect the organs of the biliary system (liver, bubble and ducts).

This is manifested in nausea, vomiting, low-grade temperature, pain in the right hypochondrium. The beings that dwells in the bladder and kidneys, are schistosoma. Cause dysuric phenomenon. In the urine of these patients can be present in the blood. Some human parasites are of great danger, and the years may not manifest itself. To refer them had. These tape worms are capable of parasite in the body in the form of larvae. The man is the blockage of the branch for this helminth. Echinococcus, which lives in the liver or the lungs, the form of bubbles (cysts). There may be several tens. The lice cause the sick of the itching and can be the cause of the development of eczema, gangrenous, and chronic atopic dermatitis by contact. In the skin of the people, the rash appears. The defeat of the person chesotocnami ticks is characterized by skin itching, mainly in the afternoon and evening and the rash. If there is in the body anopheles parasite fever, chills, dizziness, nausea, jaundice, increases the liver and the spleen.

The largest of human parasites

Some parasites are microscopic in size, and others that can reach a length of 20 m. the Most important of them are:the choice of lentets (the causative agent of difillobotrioza), pork and beef tsepni. These beings have a neck plane of the body, divided into numerous segments (proglottid). Swine tsepen reach the 4 m of length. It has the head, the body and the suction cup. Observed the hooks. The man acts as the final master.

Sometimes in the body of the people feed on the larvae of this helminth. The largest worm is bullish tsepen. The length of its body reaches up to 20 m. This parasite causes a disease, such as the beef tapeworm infection. The large species are capable of work, forming a ball in the human gut. This can be the cause of the violation of the passage of the cove. A bit more small have helminths of a group of trematodes (wide lentets). The infection may the use of the half-baked infected fish.

How to get rid of parasites? The man has no more flour you want to recover shaken under the influence of dangerous creatures of the health, but not able to do so. Independent of the therapy practically does not give good results. If you have even the slightest of symptoms, you should seek medical help.
