Photo with a description of what parasites live in the human body

types of parasites in the body

Only by carefully reading the pictures of parasites in the human body can you understand how different the members of this class are. They differ in size and shape, are the cause of a number of diseases, and have individual characteristics that help people to feed and reproduce at their own expense. Depending on the type of parasite that causes the infection, internal invasions can be divided into two groups: protozoal infections and helminthiasis.

Pathogens of protozoal diseases

These types of pathologies are caused by single-celled microorganisms or protozoa (amoebae). You can usually see what the parasites look like with a lot of magnification. Protozoa live in a person for years and can be both pathogenic (disease-causing) and harmless. There are also beneficial parasites that feed on disease-causing microbes and protect the body from infectious diseases.

Oral Amoeba and Oral Trichomonas

A protozoa that lives in the human oral cavity. When infected with these parasites, periodontal disease can develop, manifested by the accumulation of purulent discharge in the gums. Bacteria are localized in the tonsils, cavities of decayed teeth and mucous membranes.

Oral amoeba has a circular shape with a cloudy central part. Trichomonas looks like a 4-flagged pear in front.

Note!

This protozoa does not form cysts and can be transported from the oral cavity to the nasopharynx and respiratory organs. Treatment involves the use of Trichopolum or Macmirora, as well as antibiotics for the oral cavity.

Giardia

These are internal protozoa parasites. They are the causes of giardiasis. They parasitize in the vegetative stage and can turn into cysts. The posterior side of the adult trophozoites has a broad, marked shape. In the middle, two axostiles (supporting ropes) appear, dividing the lamblia in half. Each part has a core. This protozoa moves with the help of 4 flagella.

Be careful

According to statistics, more than 1 billion people are infected with parasites. You can't doubt that you are a victim of parasites.

The presence of parasites in the body is easy to detect by a symptom - bad breath. Ask your loved ones if you smell your breath in the morning (before brushing your teeth). If so, you have a 99% chance of being infected with parasites.

Infection with parasites leads to neuroses, rapid fatigue, mood swings, and then more serious diseases.

In menparasites cause: prostatitis, impotence, adenoma, cystitis, sand, kidney and bladder stones.

In women: pain and inflammation of the ovaries. Fibroma, fibroids, fibrocystic mastopathy, inflammation of the adrenal glands, bladder and kidneys develop. Both heart and cancer.

I just want to warn you that you do not need to run to the pharmacy and buy expensive drugs, which, according to pharmacists, will destroy all parasites. Most drugs are extremely ineffective and at the same time cause great harm to the body.

Cysts of parasites reach 14 microns in size and have an oval shape. There are 4 nuclei inside. Giardiasis is manifested by abdominal pain, nausea, vomiting, heartburn and fecal occult diseases.

Amoeba Entamoeba histolytica

types of parasites

The causative agent of dysentery amoebiasis belongs to various parasites of the sarcoid class. It parasitizes the human body in the form of trophozoites measuring 15-60 microns and cysts (up to 20 microns). The site of localization is the large intestine, rarely in the liver, lungs and brain. In the small intestine, the cyst membrane opens, each nucleus divides, and an 8-nucleated amoeba is formed. It causes vegetative forms in which the cytoplasm is clearly separated by the difference between ectoplasm and endoplasm.

Note!

Symptoms of amebiasis include dark red jelly-like diarrhea, a cough with "coffee" phlegm, high fever, pain in the right hypochondrium, and a desire to defecate (tenesmus).

Intestinal balantidium

The simplest organism from the class of eyelashes. It causes balantidiosis, which manifests itself in the formation of ulcers in the walls of the large intestine in humans and intoxication of the body. Balantidia parasitizes the body in the form of cysts and active silicates, which have a shape extending from 30 to 150 microns.

There is a space in the body of the lashes, which is covered with lashes to absorb food. A balantidial cyst resembles an egg with a thick shell, about 55 microns in size.

Trichomonas urogenital

how the parasites look

The parasite is sometimes called vaginal, but this is not true. Trichomonas can live in a person regardless of gender and can cause severe inflammation at the site of localization. They are located in the urethra and prostate gland in men, and anywhere in the genitourinary system in women.

These simplest organisms have only one active phase in their life cycle, they do not form cysts. Trichomonas has a pear-shaped body up to 30 microns long. In the middle of the pattern is a separating rope with a spike-like protrusion at the back end. In the front there is a flagella for movement.

Plasmodium malaria

These parasites have several species and belong to the class of blood sporozoans. A person is parasitized by pathogens:

  • three-day malaria;
  • four-day malaria;
  • tropical malaria;
  • malaria oval.

Plasmodium changes shape depending on the stage of malaria. It can be in the form of a cell surrounded by a ring, then takes the form of a ribbon, and eventually begins to divide with the formation of small cells that enter the red blood cells. In the final stage, rounded gametocytes are formed. Malaria is a severe infection and manifests itself with fire attacks by destroying red blood cells in the blood.

Trypanosomes

The simplest human parasites are flagella and cause trypanosomiasis. The pathogen looks different at each stage of development:

  • Trypanosomal. The body of the parasite has an elongated shape, there is a flagella on the back and a membrane is clearly visible.
  • Critical. Trypanosome cells stretch, the flagellum is located in front, there is no membrane.
  • metasicycle. It is the most contagious stage for humans. The trypanosome has a membrane but no free flagellum.

Important!

Pathogens can invade brain tissue and cause tissue edema. Trypanosomiasis manifests itself with fever, swollen lymph nodes and headache.

I've been feeling really bad for the last few years. Constant fatigue, insomnia, a kind of apathy, laziness, frequent headaches. There were also problems with digestion and bad breath in the morning.

Pneumocysts

pneumocysts in the body

Available as trophozoites, precysts, cysts and sporozoites. Initially, pneumocysts have an irregular round shape with a thick membrane for contact with the alveoli of the lungs and pseudopod-like growths. Appears inside vacuoles and nuclear cells. A precyst resembles an egg with nuclei inside, from which cysts emerge during division, which in turn are sporozoites.

Pneumocysts are the causative agents of pneumocystosis in humans. The disease manifests itself with dry cough, such as whooping cough and choking attacks.

Nigleria

This is a slimy amoeba. Actively moves in biological tissues & tolerates unfavorable temperatures wellYou can get nigleriosis while bathing. The parasite enters the brain through the nasal passages.

Important!

The prognosis is often fatal. The clinic is similar to meningitis (headache, stiff neck muscles). The treatment is ineffective with antibacterial therapy and drugs based on miconazole.

Toxoplasma

Widespread parasite of internal organs. Causes damage to the nervous system, myocardium, liver and spleen. It looks like an orange slice in the form of toxoplasmosis.

Helminths

This is a large group of living organisms that parasitize the human body and cause helminthic invasions. According to the external description, all helminths look like worms, but have a different structure and size. The symptoms and treatment of worms are closely related. It is enough to take a certain drug with mild invasions, accidental ones, complex treatment will be required. According to biological characteristics, human helminths are divided into straight and round. In turn, there may be flat flukes or lenteworms.

Ribbons

Images like a ribbon or a chain of several segments. Each individual has a head and neck area where new segments grow. The clinical picture of infection with these worms is characterized by general exhaustion, indigestion and intoxication.

  • Wide ribbon. It lives in the intestines and less in the stomach, causes diphyllobotriasis and can live up to 10 years. The length of this parasite in the human body reaches 15 meters. The width of each segment of the parasite body is greater than its length.
  • The pig tied the ribbon. It grows up to 3 meters and lives in the lumen of the small intestine. In the photo of the parasite in the human body, the hooks in the head area are clearly visible. For this reason, pork worms are called armed.
  • Bull tapeworm. It looks like a pig, but has no hooks and reaches a length of 10 meters. It lives in the small intestine for up to 30 years and causes Teniarinhoz disease.
  • Alveococcus and echinococcus. These worms damage the liver and can migrate to other organs (brain, lungs). The size of helminths is not more than 5-6 mm. The body consists of 3-4 parts. One of the features of worms is their ability to form bubbles filled with larvae in human organs. In this form, parasites live in the human body for up to 10 years.

Suckers

blood flows in the body

These are human parasites belonging to the class of trematodes and called flukes. The worms are localized in the liver, lungs and bloodstream. Signs of infection in the body include pain in the right hypochondrium, cough, signs of intoxication and indigestion.

  • Hepatic hemorrhage. It is a causative agent of fascioliasis living in the hepatic ducts. During puberty, the body is up to 5 cm long, resembles a leaf in shape, and has two nipples in the abdomen and mouth. The parasite's eggs are less than 1 mm long and light yellow with a cap on the pole.
  • Cat wings. A dangerous parasite of the internal organs that causes opisthorchiasis. The worms are leaf-shaped and up to 13 mm in size. There is a sucker at the beginning and middle of the abdomen, the uterus is in front, the testicles are behind.
  • Lancet Fluke. The causative agent of external dichroism is similar to a cat's wing, but the uterus is behind it and the testicles are in front.
  • Pulmonary fluke. Formed leaves up to 18 mm long with two suckers and thorns on the surface of the body. The eggs of the lung flu are oval, yellowish in color and have a characteristic cap. A person is infected by eating crustaceans.

Round Worms

This is the most popular type of parasite in the human body. Roundworm eggs remain alive in the environment for a long time. Humans carry the larvae of these parasites in their hands, animals in their fur, and insects in their paws.

human worms

Clinical signs of infection depend on the severity of the invasion. Complaints are often associated with loss of appetite, changes in body weight and discomfort in the abdomen.

  • Ascaris. Large fusiform worms. The length of the female is 40 cm, the male is 20. The worms are gray-white in color and live in pairs in the intestines. In the enlarged photo, you can see the mouth of the roundworm in the form of a cuticle with three flaps.
  • Pinworms. The most common parasites in children. The worms are small, the female is 12 mm, the male is 5. The female has a pointed tip on the teeth and bends towards the abdomen in males. Pinworm eggs are microscopic in size and are often carried under children's nails if hygiene rules are not followed.
  • Vlasoglav. In order to nurture this parasite in man, nature has endowed him with a unique body. The upper part is like hair and easily penetrates the intestinal wall. The total size of the worm is not more than 5 cm.
  • Ankilot worms. In humans, these double worms are localized in the duodenum and jejunum. An adult is up to 14 mm long and about 0. 6 cm wide. The female lays 25, 000 microscopic eggs a day.
  • Trichinella. Small worms 2-4 mm long. It is localized between the muscle fibers and wrapped in a spiral. Trichinella causes trichinosis in humans. Symptoms include muscle pain, weakness, and fever.
  • Rishta. Included in the list of rare worms. Given the photos of parasites living in the human body, the bond is particularly disgusting. It is a long worm in the form of a white thread. Dimensions can reach 1 meter. The ligament is localized under the skin on the legs, less on the abdomen and waist.
  • Toxocars. Heterosexual worms up to 18 cm long. The parasites look like ascaris in the gastrointestinal tract.
  • Acne in the gut. This human parasite is a strong cause of the disease. The size of the worm is about 3 mm, the body is almost transparent, the back is pointed, the front flaps are very different.
  • Filarias. Living creatures (females) up to 80 mm in length. The body's larvae are called microfilariae and can migrate through the body's bloodstream and cause blockage of blood vessels. Symptoms of parasites include lymphatic obstruction, elephantiasis, and heart and respiratory failure.
