Types of parasites in the human body

Necatorosis (wild worm)

This disease is caused by helminths called nectar and angworm. Invasion is manifested by the following complex of symptoms:

1. When the larvae enter through the skin, dermatitis, urticaria and various rashes appear. At the site of penetration, there is swelling, itching and burning. The invasive period lasts up to 12 days.
2. The migratory phase is also associated with allergic manifestations. In this case, the respiratory tract is damaged, and bronchitis, pneumonia, tracheitis and laryngitis occur. The patient has fever, cough, shortness of breath and hoarse voice.
3. In a few months, the intestinal phase of the disease begins. At this stage, symptoms of iron deficiency anemia and duodenitis are present. The patient has increased irritability, fatigue, and sleep disturbance. Women have menstrual irregularities.

Important! In childhood, worm infection can cause mental and physical retardation.

Giardiasis

Giardia is a protozoan parasitic disease. A quarter of the population has an asymptomatic transport of this microorganism. In the acute phase, the following signs appear:

• malfunctions in the gastrointestinal tract;
• the patient is tortured by pain in the right hypochondrium and the area around the navel;
• gas, decreased appetite, stuttering, nausea;
• diarrhea alternates with constipation, there may be frequent bowel movements (up to 5 times);
• with a subacute course, intestinal symptoms persist, the patient loses weight;
• with mass intoxication from invasion and fever;
• children have itching, hives and fainting;
• during the coprogram the protozoan cysts are found in the feces.

Amebiaza

The disease is provoked by a histological amoeba. The disease can be asymptomatic or symptomatic. There are two forms of the disease: extraintestinal and intestinal. These protozoa can affect the brain, lungs, skin and genitourinary system. But the most common is intestinal amoebiasis. Its symptoms are as follows:

• at the beginning of the disease, diarrhea appears with abundant foamy stools, then stools like jelly, like raspberry jelly, come out. Their frequency is up to 20 times a day;
• severe pain is localized on the right side of the abdomen;
• mild subfebrile condition;
• after 6 weeks the acute process may subside;
Examination
• can detect protozoa in feces.

Important! Amebiasis never goes away on its own and often recurs. If left untreated, an amoeba forms, which leads to intestinal blockage.

Difilobotriaza

Wide tape is the culprit of this disease. This representative of cestodes causes the clinical picture of the following disease:

• weight loss, irregular bowel movements, decreased appetite;
• low temperature;
• fatigue;
• cramping abdominal pain;
• anemia, weakness, dizziness, increased heart rate;
• fragments of worms can be found in feces;
• painful cracks appear in the mouth;
• depression and increased nervousness.

Tenioza

The disease is caused by swine flu. The parasite is localized in the small intestine and causes the following symptoms:

• constipation, vomiting, diarrhea, nausea;
• vomit and feces may contain segments (proglottida) of the parasite;
• anal itching, abdominal pain;
• sleep suffers, dizziness appears.

Echinococcosis

Echinococcosis can be asymptomatic for a long time. Then pain appears in the area of formation of an echinococcal cyst. Usually, the symptoms are characteristic of neoplasms of a certain organ. When the cyst ruptures, general intoxication, anaphylactic shock, and urticaria occur.

Types of parasites that live in the human body

All kinds of parasites in the human body have a detrimental effect on his health. They infect organs, feed on nutrients that are necessary for human life, and release harmful toxic substances. Therefore, it is so important to get rid of them in a timely manner.

The human body is affected by various parasites, some live inside the body, others on its surface. They differ in size, in the way they enter the body, in the characteristics of their vital functions.

What parasites live in the human body? How to get rid of them? What preventive measures are there? These issues will be discussed below.

Classification of parasites

Human parasites are very common, they are divided into groups:

1. Endoparasitesare organisms that parasitize within a person. This group, on the other hand, is divided into protozoa (consisting of a single cell) and helminths (worms). The simplest parasites in the human body are amoebae, lamblias, Trichomonas, toxoplasma. As for worms, here again there is a division into roundworms (nematodes), flatworms and tapeworms.
2. Ectoparasitesare organisms that parasitize the surface of the human body - lice, ticks, fleas, ladybugs. In addition to the fact that they feed on human blood, cause great inconvenience (bites, burns, skin wounds), they carry quite dangerous diseases: typhoid, anthrax, trypanosomiasis and others.

1. Giardia.Giardiasis infection is a fecal-oral mechanism. Once cysts (parasites still unformed, covered with a protective membrane) are removed from the anus of a sick person, they spread to vegetables, fruits, and other food products. Through poorly washed hands, stagnant water, insufficiently washed fruits and vegetables, cysts enter the human oral cavity, from where they safely reach the intestines, where they again turn into an adult and multiply again. The result is a vicious cycle that will continue until adequate treatment is ensured and hygienic measures are followed. Symptoms of the disease are weakness, fatigue, headache, diarrhea, abdominal pain and bloating. Itching may appear in the anus, skin rash, bronchial asthma. The pathology is characterized by weight loss, anemia and weakening of the immune system. Treatment - Metronidazole, Furazolidone, Tinidazole. The dosage is prescribed by the doctor.
2. Toxoplasma.Infection with these protozoa occurs through contact with infected pets. In this case, a person is an intermediate host, as the cycle of sexual development of the parasite occurs in the body of the animal. The disease is manifested by a prolonged rise in temperature to subfebrile levels, general signs of intoxication, the patient has enlarged lymph nodes, joint and muscle pain appear. Also, the functions of the gastrointestinal and visual tract are disrupted, the central nervous system may suffer, there are signs of heart disease and the endocrine system. Treatments is a complex treatment - antibiotics of the tetracycline group and sulfonamides.
3. Trichomonas.Trichomonas is sexually transmitted, the risk of infection from contact is minimal, but still exists. Symptoms of the disease in women are itching, redness of the genitals, burning and foamy discharge. Men may have difficulty urinating and have discharge. Treatment - anti-trichomoniasis.

Pinworm is an intestinal parasite

The most famous indoor parasites are peg worms. They live in the gut and cause a disease called enterobiasis. This type of parasite affects not only humans but also monkeys. Risk group - preschool children, according to statistics, enterobiasis is diagnosed in half of children from 2 to 10 years.

Worms are transmitted from person to person, you can become infected through anything that a sick person has used, or through a handshake. The main condition for the transfer of worm eggs do not wash your hands after contact, especially before eating. Worms, or rather their eggs, can be transmitted by flies and cockroaches.

Stake worms can only live in the gut, they are particularly comfortable in the small intestine, colon and large intestine. For mating, the parasites select the ileum, from where the female crawls through the anus and lays eggs in the anus. Symptoms of worms on the body are itching in the anus, allergies, fatigue, anemia, abdominal pain, exhaustion.

Roundworms - roundworms

The length of an adult can reach 40 cm. Roundworms live in the human gut, their eggs are laid naturally, then they continue their development on the ground, where they stay until they re-enter the human body. Dirty hands and unwashed vegetables and fruits are ways of infecting roundworms. Roundworm eggs are covered with a shell that does not digest in the human stomach and allows roundworms to survive and enter the intestines, where mature individuals develop.

Ascariasis can be asymptomatic for a long time. Then the symptoms appear, which depend on the location and stage of development of the parasite. In the first, migratory stage of ascariasis, the patient is concerned about fever, cough with saliva, skin rash, migraine, enlarged lymph nodes, liver and spleen. In the late stage, when the parasite already enters the intestine, defecation disorders are observed (dysentery, cholera-like symptoms, signs of typhoid fever may appear). There are painful sensations in the abdomen, a sharp weight loss and fatigue.

Wide bar

Infection with this parasite occurs through fish. This is the intermediate host of the worm. It is not necessary to eat for infection, sometimes just contact with infected fish is enough. This is why it is so important to handle the hand, the knife, the board very carefully after you have cut the fish.

Neither worms nor their larvae are transmitted from a sick person to a healthy person. Symptoms of infection are nausea, vomiting, abdominal pain, increased or decreased appetite, dyspeptic disorders. The first signs of the disease may appear one or two months after infection. As a result of the long-term presence of the parasite in the human body, pale skin, headache, increased heart rate, decreased blood pressure, weakness, anemia. The treatment aims to kill the worm. To do this, use Praziquantel, Niclosamide.

Bull Tape

Cattle tapeworm can grow up to 12 m long. is a hermaphrodite that can produce over 100, 000 eggs, which are excreted in the feces. The eggs fall to the ground, then over the plants, these plants are eaten by the cattle. In an animal's body, eggs become larvae, which are localized in the muscles. If a person eats contaminated beef, the larvae enter the gut. The larvae are not transmitted from person to person.

Adult worms have a head with four suction cups, a neck and a body composed of segments. The number of segments is constantly increasing, mature segments can be separated from the worm and crawled from the human intestines.

Symptoms of the disease are mixed, vomiting, dyspeptic disorders, increased salivation, dizziness, weakness, irritability, fatigue, abdominal pain with uncertain localization, allergies, appetite fluctuations.

To remove bovine cock from the body, there is a scheme consisting of 3 stages: preparatory (body cleansing), treatment with antiparasitic drugs (Biltricid, Praziquantel, Niclosamide), healing (diet, herbal medicine).

Pork ribbon

A person can be infected with pork strips through dirty hands, poorly cooked meat, contaminated water, an infected person can release segments of worms and larvae into the environment with vomit and feces.The worm can live in the human body for up to 15-17 years, it attaches to the intestinal mucosa and its larvae can spread throughout the body with blood flow and attach to any organ. It is especially dangerous if the larva enters the brain.

Pigs are the intermediate host; people who have frequent contact with raw meat are more likely to be affected by this parasite. The pork chain can be infected both by contact and by eating insufficiently heat-treated meat. In order for all the larvae of the pig to be destroyed in the meat, the meat must either be cooked for a long time or frozen for 2-3 weeks.

Pork stripe can affect the small intestine, liver, brain, visual organs, muscles, etc. If the worm affects vital organs, then a person may experience paralysis or even death.

Symptoms of swine fever: allergic reactions, abdominal pain, nausea and vomiting, weakness, dizziness, headache, weight loss, itching in the anus. The worm infects the intestinal mucosa, so the symptoms are very similar to enteritis.

Treatment consists of taking medicines that have a paralyzing effect on the worm, as a result of which it cannot stay in the intestinal walls and come out. But at the same time, it releases a large amount of toxic substances, which can cause anaphylactic shock in a person. Therefore, treatment should be performed only under the supervision of a physician.

Parasites in the mouth

Parasites in the human mouth can most often be represented by the following species:

• Trichomonas;
• mouth amoeba;
• Larvae of Diptera (oral miaza).

The clinical picture may be as follows:

• allergies;
• weakness, weight loss;
• bad breath;
• sensation of movement in the larynx;
• itching and sweating;
• mixed, energy loss.

Worms that live in the mouth can destroy teeth, create purulent deposits in the mucosa and tongue. Treatment is prescribed only by a doctor who takes into account existing symptoms as well as types of parasites. A prerequisite for treatment is the examination of all people in contact with the patient.

Summary

Above, not all were considered, even the most common parasites that can inhabit the human body. Importers It is important to understand the great danger of that neighborhood: worms in a person can cause very serious consequences and ultimately cause the death of their owner. Therefore, it is very important to diagnose parasites in time and get rid of them. As for preventive measures, they mainly consist of hygiene and high quality roasting of eaten meat.
