Types of parasites in the human body

Parasites that can live in the human body, there are so many. They are found worldwide, but the most common of them there are worms that are parasitic in the human intestine (worms). However, parasites can live in the human body almost anywhere: in the lungs, liver, brain, eyes, under skin, etc.

Ostrica

parazity-v-organizme-cheloveka

Pinworms – the most known human parasites that inhabit the intestines. The disease, which causes pinworms is called "enterobioz". It affects not only people, but apes. At increased risk of infection Ostricami the children are. According to various sources, the level of their involvement in the enterobioz school age is from 25 to 90%.

Pinworms are passed from one person to another. Contamination occurs via the hands, clothing and any items, which touched a sick person, provided that, after contact was made, washed hands, and eggs of pinworms came in her mouth (this is especially true during the meal). Transferring the eggs of these worms-nematodes may flies and cockroaches, obsemenyaya them food. Pinworms live in the small intestine, the caecum, the colon. They mate in the ileum, after which the female through the rectum crawls out of the anus and lays eggs in the anus.

Enterobioza symptoms are itching in the anal area, 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 reinfestation, it is important to keep hands clean, wash them after visiting any public places, after using the toilet, before eating, etc. Nails need short cut, carefully disinfect bedding and underwear, to do daily wet cleaning in the apartment.

Toksokara

Toksokara is a parasite from the group of nematodes. The disease, which causes Toksokari is called "Toksokaroz". This invasion of a person may be larval (internal and visceral), and enteric. The disease is widespread throughout the world.

Toksokaroi infection occurs by ingestion of eggs of worms in the human digestive tract. This most often occurs when eating food or water contaminated by feces of dogs. No less dangerous contact with sick animals. Natural media Toksokar are cats and dogs, foxes and wolves. Once in the human body, the larvae of the worm migrate through the blood vessels and may settle in any organ. It will depend on the symptoms of the disease.

Toksokaroz most often manifests itself in the form of allergic reactions (angioedema, skin rashes, bronchial asthma). During the exacerbations there may be an increase in body temperature to 38 degrees, but the symptoms of intoxication in this poorly expressed. Suspect Toksokaroz can be enlarged lymph nodes.

Toksokaroza visceral form is the most common, occurs with a lesion of internal organs (intestine, respiratory system, heart valves). People may feel abdominal pain in the right hypochondrium, dyspepsia, nausea.

With the defeat of the respiratory system in humans there is a shortness of breath, dry cough, asthma.

If Toksokari settle on the heart valves, the patient has weakness, bluish discoloration of the fingers and nasolabial triangle, shortness of breath.

For cutaneous form characterized by itching, feeling the stirring beneath the skin, inflammation of skin and mucous membranes.

If the neurological form of the parasite triggers the development of inflammation of the meninges and the brain tissue. This is reflected in headaches, nausea and vomiting, convulsions and other neurological disorders.

Ascaris

Gelmintyi-dlya-pohudeniya

The human Ascaris is a round worm, parazitiruyushim in the small intestine. The disease that provoke these parasites, termed "ascariasis".

The master of roundworm and the source of infection is a sick man. With the feces the eggs of worms enter the soil where they Mature to larvae. Then this soil is transferred to the food or on the hands of man, and the poor personal hygiene and poor handling of fruit, vegetables and berries – in the digestive tract. More susceptible to infection, children and rural inhabitants.

Ascariasis is manifested in different phases of their development in different ways. A phase of larval migration through the body is an increase in body temperature, there is a dry cough, rales in lungs, increase in size the lymph nodes. Children suffer ascariasis harder than adults. A characteristic symptom of ascariasis are allergic skin reactions.

While parasitism in the intestine, the patient developed dyspepsia, diarrhea is replaced by constipation, frequent abdominal pain, nausea and vomiting. From the nervous system are observed hysterical fits, insomnia, mental fatigue, headaches.

Hookworm

Ancylostoma and necator are two species of roundworms belonging to the family Ancylostomatidae and provoke the disease called "ankilostomidoz".

There are two ways of infecting the human body these parasites is fecal-oral (contaminated water, fruits, vegetables) and dermal contact with soil (penetration occurs through the skin).

Clinical symptoms ankilostomidoza: papular-vezikulyarnie rash, shortness of breath and cough, loss of appetite, nausea, abdominal pain, diarrhea, anemia with iron deficiency.

Tapeworm

A tapeworm refers to tapeworms from the squad Pseudophyilidea. These parasites live in the small intestine of man and those mammals that consume fish. Intecom infection provokes the development of diseases such as difillobotrioz. There are 12 types of tapeworms that can parasitize in the human body, however, the most common is a tapeworm.

Infection occurs by eating uncooked or raw salted fish or caviar, which contains worm eggs.

Symptoms of the presence of the parasite in the intestine: nausea, abdominal pain, anemia. In severe cases developing intestinal obstruction.

Beef tapeworm (tapeworm)

Beef tapeworm is a tape worm, belongs to the family tenid. In the larval stage affects cattle and stage of the tapeworm lives in the human body (in the intestine). The specimen provokes the disease called "beef tapeworm infection", usually in the patient has one parasite.

Human infection occurs through the alimentary after eating poorly thermally processed meat (beef).

Clinically the disease is manifested by nausea, excessive appetite, pain in the abdomen, unstable stool, allergic reactions on the type of urticaria.

Pork tapeworm

Pork tapeworm refers to parazitiruyushim tapeworms that infect mammals animals. The intermediate carriers can be pigs, dogs, rabbits, camels, but the final host is always the people. If a person is manifested in the body of the adult parasite, talking about this disease, as tenioz. If the parasite is in the body of the patient in the larval stage, the disease is called "cysticercosis".

The pork tapeworm infection occurs by eating raw meat of pigs. Sometimes sources of cysticerci are obsemenennie hands or water. Patient teniozom represents an epidemiological risk for yourself (infestation of larvae in the brain, skin, eyes or skeletal muscles) and others.

Tenioza symptoms: abdominal pain, appetite loss, irregularity, headaches, frequent dizziness, fainting (very dangerous tenioz brain and eyes).

Echinococcus

ochischenie-ot-parazitov

Echinococcus is a tape worm from the squad ciklofillid. Adults are parasitic in the intestines of dogs and cats, are found in jackals and wolves. For humans the larvae of parasites that can cause serious disease – echinococcosis.

The larvae can infect the internal organs, forming them ehinokokkovie cysts. People for echinococcal acts as an intermediate host. Infection by contact (in the process of butchering, the interaction with sick animals) or alimentary infections (when used in obsemenennoi food or water). At risk are people who are engaged in farming or who have regular contact with animals.

Symptoms may not appear for many years. If an asymptomatic stage is completed, in place of the introduction of larvae, there could be pain, itching, possible manifestations of urticaria. Also affect the functioning of the body, inside of which parasitizes the larva of Echinococcus. The increase in body temperature and fever is observed during the suppuration of the cyst.

Alveolar

Alveolar is gelmintom from the group of cestodes. The worm calls threat to human life alveokokkoz disease, which is characterized by the formation of the primary tumor in the liver with subsequent spread of metastases to other organs.

Infection occurs by ingestion in the mouth of the oncospheres of the parasite. This can happen during a hunt, in the process of butchering wild animals, contact with Pets, by eating the raw berries and herbs from the forest.

Symptoms alveokokkoza reduced to pain in the right hypochondrium, belching, nausea. There is often itching, allergic reactions. It is not excluded suppuration of the tumor with the parasite and its breakthrough in the peritoneal or pleural cavity. Metastases of alveoli can be detected in the brain and lungs.

Giardia

parazit

Giardia (another name giardii) is a parasite of the genus of flagellates related to the order of diplomonadid. Giardia provoking a disease called "giardiasis" and parasites in the small intestines of humans and many other mammals, creatures and even birds.

Lyambliyami infection occurs by the fecal-oral route: food, water and contact-household ways. The greatest value in terms of transmission is the use of raw water, contaminated food, use of public items, obsemenennih cistami Giardia.

Leading symptoms of giardiasis are nausea, pain in the abdomen, disorders of stool, excessive flatulence. In addition, patients suffer from allergic reactions, intoxication and neurotic disorders.

Despite the amoeba

Despite the amoeba is protozoinii the parasite which causes the illness called "amoebiasis". Disease manifests itself by the formation of ulcers in the large intestine with the subsequent defeat of other internal organs.

Amebami infection occurs by the fecal-oral route, after Mature cysts with water or food fall into the gastrointestinal tract of man. The possible contact transmission of the parasite through unwashed hands. Carriers of the amoebas can be flies. Another method of distribution of amebiasis is sex (anal sexual intercourse).

Symptoms of amoebiasis: an abundant mucous stool, abdominal pain, blood in the stool, weight loss, anemia. In addition, for extraintestinal amebiasis is characterized by the formation of abscesses in those organs which are affected by parasites (lung, brain, liver, etc.).

Gnatostoma

The disease is called "Gnatostomoz" cause larvae and adult nematode Gnathostoma spinigerum.

Infection occurs by eating raw meat of fish, frogs or birds, and by drinking not boiled to disinfect water.

Symptoms are manifested in cough, and pain at the site of penetration of larvae under the skin, local inflammation and fever. Characterized by severe swelling and itching. As a rule, after a week of the manifestation of the symptoms they disappear but recur again for many years. Dangerous loss of the eyeball and brain, it is often fatal.

Trichinella

gut

Trichinella are parasitic round worms, which in the larval stage residing in the muscles (extraocular, masticatory, muscles of the diaphragm), and in adulthood in the lumen of the small intestine. The disease that provoke Trichinella, called "trichinosis." It is deadly.

Human infection occurs by eating raw or poorly processed meat of wild and domestic animals.

The symptoms of the disease are expressed in loss of appetite, vomiting, diarrhea and abdominal pain. Later joined by muscle pain, swelling of the eyelids, skin rash, body temperature increased to 40 degrees.

Shistosoma

Shistosoma are worms-flukes of the genus of trematodes. They provoke the disease called "schistosomiasis". Human infection occurs during bathing, in the process of washing clothes or watering of land by water with larvae shitosom. They are able to penetrate the human body even through a holistic skin and mucous membranes.

Symptoms in the acute stage of the disease are expressed in increase of temperature up to high marks in skin itching and appearance of papules all over the body. Once the disease enters the chronic stage, it can cause symptoms of vaginitis, prostatitis, colitis, ascites, hydronephrosis, and t.. D.

Parasites that can harm the human body, there are so many. Most of them penetrate into the body of their host through the gastrointestinal tract when non-technology safe cooking and failure to follow basic hygiene procedures.
