Parasites, that are able to live in the human body, there is a huge crowd. They are found in all the world, but the most common are worms that live as a parasite in the intestine of humans (helminths). However, parasites can live in the body of the person in almost any part: in the lungs, the liver, the brain, the eyes, under the skin, etc
Ostritsy – more commonly known to the person parasites, that inhabit the intestine. The disease that cause ostritsy, takes the title of "enterobioz". It affects not only the people, but and the apes. In the high-risk group of infection Ostricami are children. According to various sources, the level of participation in the enterobioz in the preschool age is from 25 to 90%.
Ostritsy are transmitted from one person to another. The infection occurs through a handshake, clothing and all the objects that had come to a sick man, with the condition that, after the contact is not have washed their hands, and the eggs of worms got into the mouth (this often occurs at the time of food intake). Transfer the eggs of these worms-nematodes can be flies and cockroaches, obsemenyaya food. Live ostritsy in the small intestine, the cecum, colon intestine. They mate in the ileum, after which the female, through the rectum dragging of anus and deposits her eggs in the anus.
The symptoms of enterobioza act itching in the anus, the intoxication of the organism (allergic reactions, exhaustion, fatigue), anemia, increase in the level of eosinophils in the blood, insomnia, pain in the abdomen.
To avoid reinfection, it is important to take care of the purity of the hands, wash off after a visit to any of the public spaces, after using the bathroom, before eating, etc, Nails short-cut carefully disinfect bedding and underwear, the do daily wet cleaning in the apartment.
Toksokara is a parasite of the group of the nematodes. The disease that cause Toksokari, takes the title of "Toksokaroz". This invasion of the person may be larval (ocular and visceral), and also intestinal. The disease has a wide distribution throughout the world.
The infection Toksokaroi occurs when ingested eggs of worm in the digestive tract of man. This often occurs when the consumption of food or water contaminated with feces of dogs. It is No less dangerous contact with diseased animals. Native natural Toksokar are cats and dogs, foxes and wolves. Once ingested, the larva of the worm migrates from the blood vessels and can be installed in any organ. This will depend on the symptoms of the disease.
Often Toksokaroz manifests itself in the form of allergic reaction (angioedema, rash, bronchial asthma). At the time of exacerbation of the disease, there may be an increase in body temperature up to 38 degrees, but the symptoms of the poisoning of the body when this is expressed weakly. Suspect Toksokaroz can increase the lymph nodes.
Visceral form of Toksokaroza is the most common, it develops with the defeat of the internal organs (intestine, respiratory system, heart valves). The person may experience abdominal pain in the right upper quadrant, dyspeptic disorders, nausea.
When it attacks the respiratory system of the person is observed shortness of breath, dry cough, attacks of suffocation.
If Toksokari settle on the heart valves, the patient is observed weakness, blue fingers and nasolabial triangle, the shortness of breath.
For cutaneous forms characterized by itching of the skin, feeling the stirring beneath the skin, inflammation of skin and mucous membranes.
When neurological form of parasite causes the development of inflammation of the meninges and of the own tissues of the brain. This manifests itself in headaches, nausea and vomiting, cramping, and other neurological disorders.
Ascaris human round worm, parazitiruyushim in the small intestine. The disease caused by these parasites is called "ascariasis".
The owner of ascaride and the source of infection is the sick person. Along with their fecal matter for worm eggs fall into the ground, where they mature to larvae. Then, this soil is transferred to the food or to the hand of man, and in the case of a breach of the rules of personal hygiene and poor handling of fruits, vegetables, and berries in the gastrointestinal tract. In large measure the spread to the children and inhabitants of rural areas.
The ascariasis manifests itself in different stages of their development in a different way. In the migration phase of the larvae through the body, it causes an increase of the temperature of the body, appears a dry cough, wheezing in the lungs increase in size of the lymph nodes. The children carry the ascariasis is more heavy than adults. A characteristic symptom living with roundworms are the skin, allergic reactions.
During parasitic in the intestine of the sick person develop dyspeptic disorder, stools change the locks, produce frequent abdominal pain, nausea, and vomiting. On the part of the nervous system are observed hysterical convulsions, insomnia, mental exhaustion, headaches.
The anquilostomiasisa and necator are two varieties of round worms, which refer to the family Ancylostomatidae and cause the disease under the name of "ankilostomidoz".
There are two pathways of infection of the human body, these parasites is through fecal-oral (ingestion of contaminated water, fruits, vegetables) and percutaneous in contact with the ground (infiltration occurs through the skin).
The clinical symptoms of the ankilostomidoza: papular-vezikulyarnie rash, difficulty breathing, and cough, loss of appetite, nausea, abdominal pain, stool, anemia with iron deficiency.
The choice of lentets refers to the tape-worm body Pseudophyilidea. These parasites live in the intestine of man and mammals that consume fish. The infection intecom leads to the development of this disease, such as difillobotrioz. There are 12 types of tapeworms that can parasitize in the human body, however, the most common is, precisely, the choice of lentets.
Infection occurs by ingestion of raw food and non-heat-treated low salinity of fish or caviar, which contains the eggs of the worm.
The symptoms of the presence of the parasite in the intestine: nausea, abdominal pain, anemia. In severe cases, develops intestinal obstruction.
Bullish tsepen is the tape worm, belongs to the family of tenid. In the larval stage affects the cattle, and at the stage of the tape worm lives in the body of the person (in your gut). The solo leads to the disease called "beef tapeworm infection", as a general rule, in the body of the patient present a parasite.
Human infection occurs digestive through after eating poorly thermally processed meat (beef).
Clinically the disease is manifested by nausea, much more appetite, pain in the abdomen, the unsustainable exploitation of the chair, allergic reactions, spend by type of urticaria.
Swine tsepen refers to parazitiruyushim of the tape worm, which hit in the body of mammals of the animal. Intermediate carriers can be pigs, dogs, rabbits, camels, but the target host is always the man. If the person has in the body detects adult heartworms, then it is said about this disease, as tenioz. When the parasite is found in the body of the patient in the larval stage, the disease bears the name of "cysticercosis".
The infection of pork tapeworm occurs when you eat without heat treat meat of the pigs. Sometimes the sources of cysticerci are obsemenennie of the hand or the water. The patient teniozom epidemiological is a risk to himself (infection of the larvae in the brain, the skin, eyes or skeletal muscles), and others.
The symptoms of the tenioza: abdominal pain, deterioration of the appetite, disorder of the chair, frequent headaches, dizziness, even handled the fainting state is extremely dangerous tenioz of the brain and the eyes).
Echinococcus is a tape worm in the body of the ciklofillid. Adults live as a parasite in the intestine of dogs and cats that are located close to the jackals, and wolves. For the man are dangerous larvae of the parasites, that are capable of causing a serious illness – echinococcosis.
The larvae can cause damage to the internal organs of the person, forming in them ehinokokkovie cysts. The man for echinococcal acts as intermediate host. The infection occurs from contact (in the process of cutting, in the interaction with the sick animal), or digestive, over (when the consumption of obsemenennoi food or water). In the risk group are persons engaged in livestock or have a permanent contact with the animals.
The symptoms of the disease may not manifest itself for many years. When the asymptomatic stage ends at the point of introduction of the larvae to produce pain, itching in the skin, there may be manifestations of the hive. In addition, he suffers from the operation of the body, within which the parasite of the larva by a cyst hidatídico. The increase of the temperature of the body, and the fever occurs at the time of the suppuration of a cyst.
Alveolar is gelmintom of a group of cestodes. The worm is called dangerous for the human life the disease alveokokkoz, which is characterized by the formation of main focus in the liver with the subsequent distribution of the metastases in other organs.
The infection occurs when it is hit in the mouth oncospheres parasite. This behavior may occur during hunting, in the process of cutting of the wild animals, contact with pets, consumption of foods from berries and herbs from the forest.
The symptoms of the alveokokkoza are reduced to pain in the right upper quadrant, belching, nausea. Often there is itching of the skin, allergic reactions. It is not excluded, the resentment of the tumors with a parasite, and its progress in the abdominal or plevralnuyu the cavity. Metastasis the alveoli can be detected in the brain and in the lungs.
Giardia (another name giardii) is a parasite of the family of flagellates related to the patrol diplomonadid. Giardia cause disease under the name of "giardiasis and lives as a parasite in the intestine of the person, as well as many other mammalian beings and even birds.
The infection lyambliyami occurs by the fecal-oral route, through: food, water, and distance-domestic ways. The greatest value in the sense of the transmission of the infection is the consumption of crude oil in the water, contaminated food, public use of the objects, obsemenennih cistami giardia lamblia.
The main symptoms of giardiasis is nausea, abdominal pain, disorders of the chair, the excess of gases. In addition, patients who suffer from allergic reactions, poisoning and neurotic disorders.
Histological amoeba is protozoinii the parasite that causes the disease known as "amoebiasis". Manifests itself the disease the education of ulcers in the gut fat with the subsequent defeat of other internal organs.
The infection amebami occurs by the fecal-oral route, after the maturity of cysts in water or food enters in the intestinal tract of humans. It is possible to contact the path of transmission of the parasite through unwashed hands. Vectors of the amoebas can be the fly. Another form of spread of the amebiasis is the gender of the path (anal sex acts).
The symptoms of amebiasis: abundant in the mucosa of the chair, abdominal pain, impurity of the blood in the stool, weight loss, anemia. In addition, for extraintestinal amebiasis characterized by the formation of abscesses in organs, which will surprise the parasites (the lungs, the brain, the liver, etc).
The disease under the name of "Gnatostomoz" cause the larvae and Mature nematode Gnathostoma spinigerum.
Infection occurs by ingestion of food raw the flesh of fish, frogs or birds, as well as if the drink is not boiled, not water that is free of bacteria.
The symptoms of the disease are manifested in cough, and pain in the place of penetration of the larvae beneath the skin at the site of inflammation and the increase of the temperature of the body. Are characteristic of strong swelling, and itching of the skin. As a general rule, after a week of the manifestation of the symptoms disappear, but recur again over many years. Danger of the defeat of the eyeball and brain, it often ends up fatal.
Trichinella are round worms, parasites in the larval stage living in the muscle (oculomotor, masticatory muscles of the diaphragm), and into adulthood – in the lumen of the small intestine. The disease, which cause Trichinella, is called "trihinellez". It is life-threatening.
Human infection occurs by eating raw or improperly processed meat of wild and domestic animals.
The symptoms of the disease are manifested in the loss of appetite, vomiting, diarrhea, and abdominal pain. In the future come together muscle aches, swelling of the eyelids, skin rashes, the body temperature increases to 40 degrees.
Schistosoma worms are-flukes-type trematodes. Cause the disease under the name of "schistosomiasis". Human infection occurs during bathing, in the process of washing clothes or irrigation water in the soil with the larvae shitosom. They are able to penetrate into the human body, even through the integral of the epidermis and of the mucous membranes.
The symptoms in the acute phase of the disease are manifested in the increase of the temperature up to the high rating, itchy skin and the appearance of papules all over the body. After the disease goes into the chronic stage, the infected, can occur symptoms of colpitis, prostatitis, colitis, ascites, hydronephrosis, etc
The parasites, which are able to cause harm to the human body, there is a huge crowd. Most of them penetrate into the body of their master through the gastrointestinal tract when non-compliance of the technology of safe preparation of food and failure to observe basic hygienic procedures.
