List of parasites in the human body

Types of parasites in the human body is exceptionally diverse. One of them, along with Metazoa and protozoa are also viruses, bacteria and fungi that parasitize the human body, although in the medical traditions of viruses and bacteria are not considered parasites.

types of parasites

In humans various types of parasites are localized not only in the intestine, as is commonly believed, but in many other organs: blood, tissues, muscles, joints, brain and even eyes.

Particularly affected by it such internal organs as the gastrointestinal tract, liver, lungs, heart.

The imbalance is compounded by the General intoxication of the human body due to the toxins released by parasites that can lead to the development of a number of diseases up to cancer. Often, diseases caused by parasites, become chronic.

A particular danger lies in the fact that parasitic diseases are caused by symptoms typical of other, often intestinal infections, therefore, of great importance is the timely differential diagnosis to identify the species of the parasite and to develop appropriate treatment strategy.

The species of human parasites in General can be divided into two large groups:

  • ectoparasites are parasitic on the body surface and which feed on the blood of humans (bedbugs, fleas, lice, mites); they are the carriers of pathogens of such diseases as encephalitis, typhoid, anthrax, etc.;
  • endoparasites, parasitic on the internal organs and cause serious diseases; these include protozoa (Giardia, amoeba, Trichomonas, Toxoplasma) and helminths – parasitic worms (worms).

Classification of parasites

Let us consider in more detail the main types of endoparasites of man. The appearance of many of them can be seen only under the microscope, and some, especially helminths, affect its size. Let's start with the simplest:

  • Giardia along with dysbiosis are also the cause of hypovitaminosis, anemia and General intoxication of the organism.
  • Toxoplasma affect the brain, eyes, heart muscle, nervous system, but the special danger they pose to pregnant women because of the risk of fetal death or severe lesions.
  • The amoeba can cause amoebic dysentery, amoebic encephalitis and other dangerous diseases.
  • Trichomonas are sources of infectious diseases of the genitourinary system.

The most common parasites

Eastern Dens, Dens lanceolate, hepatic Dens, Siberian Dens, pinworms, ascarids, head lice, Giardia, Siberian Dens, cat Dens, blood flukes, bovine and porcine apni.

The most common endoparasites in are, of course, helminths (worms), which, according to various estimates, infected more than 80% of the world population.

A huge number of these parasites are divided into basic types:

  • nematodes – round worms (roundworm, pinworm, the species Trichinella, whipworm, etc.);
  • cestodes – tapeworms (lantecy, pork and beef tapeworm, tapeworm, etc.);
  • trematodes – worms-flukes (liver, blood, lung, and flukes that live in the intestines).

Sometimes you can find a more General classification, according to which all types of parasites people are divided into:

  • translucens (intestinal), which are parasitic in the intestine;
  • tissue, locatam in other organs and tissues.

However, most of the worms at different stages of their life cycle and are tissue, and intestinal development period with the corresponding symptoms.

Consider a brief description of the most common types of worms.

Roundworms (nematodes)

  • Roundworm – roundworms are the most common length from 20 to 40 cm, parasites in the small intestine, but first migrate in the human body, affecting the blood and respiratory system. Together with the intestine of these parasites can be detected in the liver and gall bladder, heart and lungs. A common symptom of ascariasis and allergic reaction.
  • Pinworms – small worms, up to 1 cm, which affects the intestine and which result in enterobiasis with disorder of the digestive tract, exhaustion, sleep disorders, etc. the Characteristic symptom of pinworms is itching in the anus, where they lay their eggs.
  • The species Trichinella – these microscopic worms (their size only a few millimeters) lead to severe diseases – trichinosis, which can if untreated lead to death. Adult species live in humans in the muscles (respiratory, face, etc.), causing muscle pain, fever, swelling, allergic skin rash.
  • Vlasoglavy – small worms (up to 4.5 cm, with the front part of the body in the form of threads), larvae of which cause trihozefalez with diarrhea, acute abdominal pain and other symptoms that resemble appendicitis. As a result of intoxication anemia.

Tapeworms (cestodes)

  • A tapeworm, body length of which reaches up to 10 m, leads to the development in difillobotrioz with nausea, weakness, vomiting, unstable chair, asthenia and anemia.
  • Pork tapeworm has a length of from 3 to 8 m, a parasite mainly in the small intestine and causes two diseases: taeniasis with dyspeptic, asthenic-neurotic and abdominal syndromes, and cysticercosis with ebrietas, intestinorum, allergic and respiratory symptoms. Depending on the localization of tsistitserki affects the muscles, brain, heart, eyes, etc.
  • Beef tapeworm whose length may reach 18 m, vulputate causes the tapeworm infectio and is considered one of the most dangerous types of worms. If you do not do deworming, it can stay in the body for up to 18-20 years! Is localized in the large intestine, causes severe intoxication with their waste products, as well as diarrhea, nausea, vomiting, abdominal pain, anemia, allergic reactions and problems with the nervous system.
  • Dwarf tapeworm length of only 1.5-5 cm source in gimenolepidoz with dyspeptic pain and asthenic-neurotic syndrome affecting primarily the digestive and nervous system, and liver.
  • Echinococcus is the most small band vermis – its length is from 2, 5 to 8, rarely 9 mm, but the infection it has terrible consequences such as liver and lung, where they form cysts and tumors which cause dysfunction of these organs.

Sources of infection

istocni infection

The lesson, like other intestinal diseases, is often a "disease of dirty hands", which leads to accumulation of eggs and larvae of helminths on the human body:

  • when you do not wash their hands after using the toilet and before eating;
  • do not wash vegetables, fruits and greens that are consumed raw;
  • do not put meat and fish sufficient heat treatment;
  • when consumed incorrectly salsa fish and fat;
  • leave food accessible to flies and cockroaches;
  • use the feces as fertilizer on the garden-hortus areas;
  • swimming in the ponds;
  • contact with stray animals.

However, from your pet can also be infected with worms, because often animals serve as intermediate hosts for helminths, but the primary host is man.

Methods of struggle

  • From a very early age to instill in children the habit of washing hands. They need it to do more, as they constantly Potter in the sand, the ground, the puddles, where the most favorable conditions for eggs and larvae of parasites, and contact with Pets and street animals.
  • If you experience any discomfort, we cannot exclude helminthiasis, it is recommended to conduct appropriate tests on the video to determine the specific type of helminth (against most of them there are medications.
  • If parasites are detected in one family member, the drugs from helminthiasis must take all.
  • Folk medicine knows many ways how to get rid of the worms, and they give a good effect.
  • Do not leave open cooked meals, bread, pastries, etc. that flies or cockroaches carry eggs of intestinal worms – not left them on the products.
  • Carefully observe the temperature regime in the process of cooking: meat and fish, which are often found helminth eggs, to boil/fry/bake.
  • Rinse well in tap water vegetables, fruits, greens that are consumed raw.
  • Regularly deworming Pets.
  • To abandon the use of feces as fertilizer on their garden-hortus sites.
  • When traveling to exotic countries are very wary of the local cuisine, especially the street – there is no guarantee that with them you don't catch some exotic helminth.
  • Cleanse from parasites for 1 year;
  • Due to the tanning substances, revitalizes and protects from parasites liver, heart, lungs, stomach, skin;
  • Eliminates putrefaction in the intestines, destroys the eggs of parasites thanks moleculo F.

Certified, recommended by doctors-in helminthologists remedy for getting rid of parasites in the home. Has a pleasant taste that children love. Consists exclusively of medicinal plants collected in ecologically clean areas.

What worms can live in human muscle?

Not all parasites that get into the human digestive system, able to migrate to other organs, muscles and tissues. Most often in the muscles, settle the larvae of the genus the species Trichinella nematodes, the eggs of which enter the body with raw or insufficiently assuming meat.

The species Trichinella larvae affect not all the muscles – they can be found in bends of limbs, chewing and facial muscles. The first worms are in the muscle fibers already in 2-3 weeks after infection, but discomfort in this period are not shown. Gradually their number increases, they form a spiral, is joint and muscle pain, signs of severe intoxication.

After penetration the species Trichinella in muscle, they die quickly, because the human body unsuitable for the growth of these parasites.

tapeworm – tapeworms penetrate the muscle rarely the species Trichinella, found in warm latitudes. Man is an intermediate host for the larvae of the worms are actively growing and they multiply in the organism of animals. Helminth eggs are carried to all internal organs, penetrate into the muscle fibers, which form cysts.

Infection with larvae of the pork tapeworm causes cysticercosis disease, infection comes from diseased animals, the use of dirty vegetables and fruits, which are in contact with the ground.

Symptoms of parasites in human muscle

parasites in muscles

If the parasites settle in the muscles of the human the symptoms of infection are often similar to food poisoning, colds, and the presence of worms in the body the person thinks in the least. Long destruction of muscle fibers helminths is fraught with serious complications, only high-quality and comprehensive diagnosis will help to detect the presence of pathogenic worms.

Main symptoms:

  • dyspeptic disorders flatulence, nausea, diarrhea and diarrhea, pain in the right hypochondrium, enlarged liver;
  • rapid weight loss due to inflammatory processes in the digestive tract;
  • allergic reactions such as rashes, redness of skin, itching;
  • in the stool contains fat;
  • a slight increase in temperature, weakness;
  • tachycardia.

What tests will help to identify parasites:

  1. The most informative diagnostic method for the detection of parasites in the muscles – ELISA, the analysis accuracy is over 90%. Based on these results, we can draw conclusions about the type of helminth, stages and severity of the disease.
  2. Less accurate, but cheaper and available method of diagnosis – PCR, a study should be done several times at intervals of 5-7 days.
  3. Additionally, the doctor to prescribe a stool sample and blood test.
  4. The reaction Cazoni – helps to detect Echinococcal.

You should not engage in self-diagnosis, make de-vermis drugs without prescription – all drugs for the treatment of helminthiasis-toxic, have a number of contraindications and side effects.

Preventive measures

Prevention of helminthiasis is properly heat-treated meat should be boiled or roasted in small pieces with the lid closed at least 25-35 minutes. The pre-product can be frozen, marinated in vinegar or lemon juice – the parasites are killed at low temperatures, do not tolerate an acidic environment.

All the kitchen utensils used for cutting meat, wash with hot water with soda. You can't buy bacon, ham, sausage in suspicious places, especially if you do not observe storage conditions and commodity neighborhood.

To avoid infection, you should limit contact with palor animals, pet need regularly antiparasitic prophylaxis. The basic rule is to wash hands thoroughly, vegetables and fruits, eat on the street.
