Types of worms in humans

Helminthiasis is a widespread disease. Suffer from it often, but in children and in cases where infection adult worms are also not uncommon. This disease is one major disadvantage and lead to serious consequences. Because it is very important to understand how to diagnose problems and how to fix it. It is necessary to consider many circumstances, and especially the kind of worms that came to the body. Parasites are of different types differ in symptoms and severity. Therefore, it is necessary to consider the different types of worms in humans and their main features.

what are the worms

Varieties of worms very much. Most of them characteristic of adaptation exist in the body of the host only one species (any animal or human). This means that other animals will not be harmed by such infestation, as the parasites their body dies. Therefore, there is a lot of worms that are harmless to humans. At the same time, the threat of worms and microorganisms too much. To understand what should be afraid of, you need to figure out what are the worms, stabilendam in the human body.

They can be divided into groups, each of which includes several representatives. Of these groups is called the round and tapeworms, flukes and protozoa.

Shuttle

Another name for these worms is nematodes. This type of worms is considered the most common. They are characterized by a round body shape in cross-section. The body length of different species of worms can vary from 5 mm to 40 cm in life, they usually choose the intestine, but easy to move to the host body and can coloniad other organs.

The wide distribution of nematodes is due to the fact that the infection is very easy. The intermediate host is not required, and they are transferred from one infected to another. Also, infections can develop by eating unwashed fruits or vegetables. Therefore, infection with these helminths is special for children because they tend to break the rules of hygiene.

The main representatives of the shuttle, which can live the human body are:

Pinworms

It is a small parasites (5-10 mm), with the body grey color. Wants to live in the intestines. When present in the body is a disease called enterobiasis. It can be moved, when the non-compliance with the rules of hygiene, because the eggs of these worms enter the body through the mouth.Females lay eggs in the anus, which causes severe itching. The patient scratching the area where the eggs are on the skin of the hands and under the nails. The sexually mature species the worm develops within 2 weeks. The lifetime of worms about two months. During this period, the patient has disturbed activity of the gastrointestinal tract, and more parasites accumulate in the body, the more intense the symptoms of enterobiasis. They are the following phenomena:

what are the worms in the human body
  • the presence of itching in the anus (in female patients it can affect the genital tract);
  • sleep disorders (insomnia, interrupted sleep);
  • admixture of blood or mucus in the stool.

These features indicate an infection pinworms. If untreated, the patient will deteriorate, because the parasites block absorption of nutrients. It affects the health and immune system.

Roundworm

Such worms is notable for its large size, the body temperature can reach 40 cm the best place for their habitat is the small intestines, but sometimes found in the heart, liver and lungs. Moving the host organism, the roundworm can cause damage to internal organs. Due to the presence of people develop allergic reactions, digestive disorders, possible internal bleeding. For children, these parasites are especially dangerous because they slow down the development process. Infections develop due to dirty food and dirty hands.

Ascarid is characterized by high fertility, so the infection is very dangerous. When the egg is formed in the larvae, they, along with the blood moves through the human body, penetrates the respiratory system.

Because of this, the patient may begin coughing and asthma attacks. The lifespan of adult worms for a maximum of one year, and during that time, it can significantly hurt people. His presence in the body show symptoms such as:

  • nausea;
  • anemia;
  • rashes;
  • increases in infectious diseases due to lowered immunity.

Hookworms

In this case, the infection occurs through the skin or if swallowed larvae. Blood they can be the lungs and heart, but rather the small intestine. Hookworms live for about 4 years, when the hookworm.

Symptoms:

  • fever;
  • increased salivation;
  • eosinophilia.

Pathology occurs in the running stage of infection, when the body accumulates a large amount of worms. In the early stages can be asymptomatic, which will detect pathology of the can accidentally.

Whipworm

what are the worms in the liver

These worms want to stay in the colon, lignum walls and feeding on blood. Is small in size (3-5 cm) and very high toxicity. If the parasite penetrates into the cecum, it leads to appendicitis. The host organism should be through the mouth. The eggs of the whip worm is moved through the body in the bloodstream, but adults live only in the colon. His life expectancy is about 5 years. Its ability to produce toxins, whipworm can greatly harm the body. The problem is that it is very difficult to diagnose, because the initial stage in the development of an attack without pathological symptoms. With the progression of the disease can be detected by:

  • nausea;
  • headache;
  • dizziness;
  • diarrhea;
  • spasms.

Toxocara

These worms live in the body of the dog, but can live with a man. Infection occurs through contact with sick animals. The worm can reach a size of 15-30 cm, while in the human body, this does not happen. These worms live in humans only larvae. They actively move through the body, cause the development of allergies and harm the internal organs.

The Species Trichinella

It is a microscopic, because its dimensions do not exceed 5 mm. However, because it may develop trichinosis, which raise the temperature and fever. This attack is possible, using meat that is not properly cooked. Without the necessary heat treatment of pathological micro-organisms in meat, not die, and penetrates into the human body. Live Trichinella muscle tissue. If a favorable result, the patient recovers in about 4 weeks, but if the body has too many of these parasites, the patient may die.

This group of parasites is the most common, but there are other kinds of worms, which should be treated.

Tapeworms

If you look at all the varieties found in humans, worms, tapeworms are one of the most dangerous. The greatest risk is associated with the size, because this type of parasite can reach a length of 18 m. therefore, their effect on the human body is very unfavorable.

All the time their life requires a change of the owner. Some part of the tapeworm live in the body of cloven-hoofed livestock, which is transferred to the people.

The most common of these parasites:

Dwarf tapeworm

This representative of tapeworms characterized by a small size – only 1.5–5 cm Infestation is the bite of an insect vector. The dwarf tapeworm eggs reach the small intestine where it Matures to the larva stage, and then spread to the liver or the gastrointestinal tract. Also, this helminth can affect the functioning of the nervous system. The main symptoms of this infestation are:

  • poor appetite;
  • nausea;
  • nervousness;
  • headache;
  • conjunctivitis;
  • allergic reactions.

Tapeworm

Because this helminth develops difillobotrioz. Its size can be 15 m. Infection begins by eating freshwater fish, which has not passed sufficient heat treatment. Worms, the eggs penetrate the intestine, with the development of adults.

The duration of their life – about 25 years. The presence of these worms in the body leads to exhaustion and weak immune system, allowing infection to develop again. Pathology indicative features such as:

  • severe abdominal pain;
  • problems with the functioning of the digestive system;
  • anemia;
  • allergies;
  • tissue necrosis.

Pork tapeworm

This type of attack happens when a person eats infected pork. These worms have a body length of 8 m. They want the parasites in the intestines. Life expectancy is more than 10 years, and during this period, the helminth causing great damage to the host organism. It causes intestinal obstruction, exhaustion of the nervous system and the physical nature, weakens the immune system. When present in the body has the following deviations:

  • allergic reactions;
  • disorders function of the digestive system;
  • anemia;
  • pathology of the nervous system.

Beef tapeworm

He is the most significant parasites, to achieve the size 18 m. People get these worms by eating poorly cooked beef. If such infestation high risk of damage to the walls of the small intestine or exposure to toxins. Beef tapeworm life expectancy can be several years. It is especially dangerous that the human body can live a few adults.

Identify the pathology of one of the following:

  • severe pain in the abdomen;
  • poor appetite;
  • the stomach ailments.

Echinococcus

These worms human is the intermediate host, adults live in dogs and cats. People infected by contact with domestic or stray animals, or by eating dirty vegetables and herbs. Despite the fact that a person can only live larvae, even though they can cause serious diseases – echinococcosis. It affects the internal organs, causing growth cystic formations. The presence of Echinococcus in the body of the question is:

  • severe pain in the upper abdomen;
  • rashes;
  • hives;
  • chills;
  • signs of a fever.

Alveolar

what are the worms Toxocara

The size of these parasites is small – only 4 mm. To tolerate his dogs and other members of the family Canidae. To get this kind of attack can be by eating unwashed food or in contact with animal carriers. These worms are very dangerous because people can die. Settling of parasites in the liver leads to the formation of lauriota that is carried throughout the body. This causes the formation of a large amount of damage. They can affect the kidneys, heart, bladder, and pancreas. It is very important to detect infestations early, as long it is not treated.

Species of parasitic worms that belong to this group, very dangerous. It is necessary to observe preventive measures to prevent infection with them, and at the first sign of infection, seek medical attention.

Whale tail

This group includes worms, on the surface of the body, which are a sucker. With their help, the parasites cling to the walls of the internal organs, they absorb nutrients or blood. They are flat, similar in appearance to the wood plates, and their size can reach 1.5 m. Infestation of these worms occurs when the use of seafood and fish, when insufficient heat treatment.

Pay to the caves

It is a small size – they are not more than 5 cm Another name for helminth – cat fluke. It causes a disease called opisthorchiasis. Infection of humans occurs by eating meat and fish, after a bad heat treatment. This parasite attaches itself to the liver. Feature of the liver Fluke is its hermaphroditism, where he actively propagated even when injected into the body of only one person. He is very prolific. The symptoms of the disease is weak, but because of the high reproductive ability, which can lead to liver destruction in a very short time. In addition, the patient may develop pancreatitis, gallbladder inflammation or ulcers. Its signs are:

  • muscle and joint pain;
  • high temperature;
  • diarrhea;
  • constipation;
  • a rash on the skin.

Siberian Fluke

Its dimensions are small and do not exceed 1.5 cm helminth parasitism prefer the gallbladder and its ducts. To diagnose this infection is easiest in the early stages, because its symptoms at the moment. The transition to a chronic form, they are smoothed.

If the body Siberian Fluke such violations occur, such as:

  • disorders of the gastrointestinal tract;
  • temperature rise;
  • pain in joints and muscles.

Helminthiasis caused by these species of parasites, not less dangerous than the other. If a large number of pathological organisms, the patient's condition is much worse, and if you ignore the harmful symptoms of developing complications.
