Pork thistle

Pig milk tie refers to parasitic tape worms that affect the body of mammals. Intermediate carriers can be pigs, dogs, rabbits, camels, but the ultimate host is always human. If a person has an adult parasite in the body, then they say such a disease as a shadow. When the parasite is in the body of the patient in the larval stage, the disease is called “cysticercosis”.

Infection with pork chain occurs when eating thermally untreated pig meat. Sometimes the sources of cysticerci are the seeds or water. A patient with a shadyosis represents an epidemiological danger both for himself (infection by the larvae of the brain, skin, eyes or skeletal muscles), and for others.

Symptoms of shadows: pain in the abdomen, impaired appetite, upset of the chair, headaches, frequent dizziness, fainting (extremely dangerous brain and eye shadow of the brain).

For the treatment of shinosis, the patient is placed in a hospital. Under the supervision of doctors, he is prescribed anthelminthic drugs (Praziquantel, Nichlosamide), after which the patient takes a salt laxative after 2 hours, which allows getting rid of the segments and eggs of the worm. For the treatment of eye and brain cysticercosis, surgical intervention is necessary.

Echinococcus

Echinococcus is a ribbon worm from the cyclophyllide order. Adult individuals parasitize in the intestines of dogs and cats, are found in jackals and wolves. For a human, larvae of parasites are dangerous, which can cause a serious disease – echinococcosis.

Larvae can affect the internal organs of a person, forming echinococcal cysts in them. A person for echinococci acts as an intermediate host. Infection is carried out by contact (in the process of cutting carcasses, by interacting with a sick animal), or by alimentary route (with the use of contaminated food or water). At risk are people who are engaged in animal husbandry or who have constant contact with animals.

Symptoms of the disease may not appear for many years. When the asymptomatic stage is completed, at the site of the introduction of the larva there are pains, skin itching, and manifestations of urticaria are possible. In addition, the functioning of the organ inside which the larvae of the echinococcus is parasitic suffers. An increase in body temperature and fever is observed during suppuration of the cyst.

A full cure for echinococcosis is possible only surgically. The cyst is removed, trying not to damage its shell. If the bladder is very large, then perform its puncture and sucking the contents. Before the operation and after it, the patient is prescribed antiparasitic drugs: Praziquantel, Albendazole, Mebendazol. In the case of a radical cyst removal, the prognosis for recovery is favorable.

Alveococcus

Alveococcus is a helminth from the group of cestodes. The worm calls alveococcosis, which is dangerous for human life and is characterized by the formation of a primary lesion in the liver, followed by the spread of metastases to other organs.

Infection occurs when a parasite enters the mouth of the oncosphere. This can occur during hunting, during the cutting of carcasses of wild animals, in contact with domestic animals, when eating unprocessed berries and herbs from the forest.

Symptoms of alveococcosis reduce to pain in the right upper quadrant, belching, nausea . Often there is a skin itch, allergic reactions. It is not excluded suppuration of a tumor with a parasite and its breakthrough into the abdominal or pleural cavity. Alveococcal metastases can be found in the brain and in the lungs.

Treatment of the disease operative, but should be supplemented by the use of antiparasitic drugs (Levamizol, Mebendazol).

Lambliya

Lamblias (another name for giardia) are parasites from the flagellate genus belonging to the order Diplomonadid. Lamblias provoke a disease called “Giardiasis” and parasitize the human small intestine, as well as many other mammalian creatures and even birds.

Infection with Giardia is a fecal-oral route: food, water and contact-household methods. The most important in terms of transmission of infection is the use of raw water, contaminated food, the use of public objects, seeded with lamblia cysts.

The leading symptoms of giardiasis are nausea, pain in the abdomen, stools, excessive release of gases. In addition, patients suffer from allergic reactions, from intoxication and neurotic disorders.

Giardiasis is treated with antiprotozoal drugs (Tinidazole, Metronidazole, etc.), as well as with the inclusion of enzymes, cholagogues and enterosorbents into the treatment regimen.

Histological amoeba

Histological amoeba is a protozoal parasite that provokes a disease called amebiasis. The disease manifests itself in the formation of ulcers in the large intestine, followed by the defeat of other internal organs.

Amoeba infection occurs by the fecal-oral route, after mature cysts from water or food enter the human gastrointestinal tract. A contact path of transmission of parasites through unwashed hands is possible. The carriers of amoebae can be flies. Another way of spreading amoebiasis is through the sexual way (anal intercourse).

Symptoms of amoebiasis: abundant mucous stool, abdominal pain, impurities of blood in feces, weight loss, anemia. In addition, for extra-intestinal amebiasis, the formation of abscesses in those organs that are affected by parasites (lungs, brain, liver, etc.) is characteristic.

Tinidazole, Metronidazole, Ornidazole are prescribed for treatment of intestinal amebiasis. If the patient has intolerance Metronidazole, then it is replaced with Erythromycin or Doxycycline. The duration of therapy is determined by the severity of the course of amoebiasis.

Gnathostoma

The disease called “gnathostomosis” causes larvae and sexually mature nematodes Gnathostoma spinigerum.

Infection occurs when unprocessed meat of fish, frogs or birds is eaten, as well as by drinking unboiled non-contaminated water.

Symptoms of the disease are manifested in cough and pain in the place of penetration of the larva under the skin, in local inflammation and increased body temperature. Characterized by severe swelling and itchy skin. Typically, a week after the manifestation of symptoms they disappear, but they recur again over the years. Danger of the eyeball and brain, it often ends in a fatal outcome.

Treatment involves the use of anthelmintic drugs (most often prescribed Albendazole) and surgical intervention. During the operation, parasites are removed from the skin. Trichinella

Trichinella are round parasitic worms that live in the larval stage in the muscles (oculomotor, chewing muscles, diaphragm muscles), and in adulthood – in the lumen of the small intestine. The disease that triggers trichinella is called “trichinosis.” It is deadly dangerous.

Infection of a person occurs when eating raw or poorly processed meat of wild and domestic animals.

Symptoms of the disease are manifested in loss of appetite, vomiting, diarrhea and abdominal pain. In the future, muscle pains, eyelid edema, rashes on the skin, body temperature increases to 40 degrees.

Treatment of parasitic invasion is carried out with the help of Mintezol, Vermox, Albendazole. At the same time prescribe antihistamines, and, as necessary, corticosteroids.

Schistosome

Schistosomes are trematode trematode worms. They provoke a disease called schistosomiasis. Infection occurs during bathing, during washing clothes or watering the land with water with larvae of schistosomes. They are able to penetrate the human body even through holistic integuments and mucous membranes.

Symptoms in the acute stage of the disease are manifested in the rise in temperature to high marks, in the skin itching and in the appearance of papules throughout the body. After the disease passes into the chronic stage, the symptoms of colpitis, prostatitis, colitis, ascites, hydronephrosis, etc. can appear in the infected stage. For the treatment of the disease, anthelmintic drugs are used: Niridazole, Praziquantel, Metrifonate and so on. Surgical intervention is required for complications of urogenital schistosomiasis.

There are a lot of parasites that can harm a human body. Most of them penetrate the body of their host through the gastrointestinal tract if the technology of safe cooking is not respected and if elementary hygienic procedures are not performed.
