Parasites in the human body

Enemies, as they say, "You need to witness. " You need to understand who we are dealing with. No discount will be given to illiterate persons on this issue. Let us be armed with information that can be used in practice to maintain our health. This will not give some parasites the slightest chance to destroy our precious lives.

Parasites-who are they?

Parasites(from Greek parasites-parasites, parasites)-lower plants and animal organisms that live outside or inside another organism (host) and feed on it. Parasites live parallel lives in our bodies, feeding on our energy, cells and food (including the healthy products we eat).

Some parasites will spend their lives in the host or the entire body. They get food and shelter from food without causing any visible harm to the host's body.

Certain parasites can stimulate the host and affect its function. Others destroy the host’s tissues and release specific toxins that lead to physical health and the development of various host diseases.In the human bodycan parasite various species: fungi, bacteria, viruses, protozoa and worms.

Parasitesgo through a complex development cycle in their life: some parasites need to change several hosts, and the parasites undergo intermediate development (the so-called larval development stageWorm worm). In the body of the last host, the worm becomes sexually mature and becomes as dangerous as possible.

Parasites are classified as follows:

• Fungus
• Virus
• The simplest parasite
• Worms (worms, worms)
• Parasites of crustaceans
• Spider parasites
• Insects (mainly sucking blood)

1. Fungi.

These aremicroorganismsthat affect the human body, which can be deposited on the skin surface and the mucous membranes of internal organs at the same time. Diseases caused by pathogenic fungi are calledfungal diseases. There arefungal diseases of the skin and nails(dermatophytes) and fungal diseases of internal organs. Animals are also susceptible to fungal activity-they can poison the body due to mycotoxin poisoning (mycotoxin poisoning) that affects plant feed. The types of fungal diseases are different. Some people only get sick or only animals, while others are infected by animals. Pathogenic fungi cause fungal diseases that are considered infectious diseases.
There are hundreds offungi, two of which are particularly dangerous to humans. The first fungus-Cryptococcus(Cryptococcus neoformans)-causes meningitis (inflammation of the brain and spinal cord membrane). Usually, this kind of cryptococcus is distributed in the feces of birds and is found in fruits, vegetables, animal milk and soil. The second fungus-Candida(Candida albicans)-causes diaper rash, mucosal candidiasis, balanitis, thrush, mycosis, onworm disease (nail damage), lip ulcer, nailGully, athlete's foot (toe fungal disease), genital disease.Fungi like candies, they mainly feed on sugar and starch, but like any living thing, they also need amino acids, vitamins and minerals.
Fungusis ​​an independent civilization, it is its own parallel world. They can withstand temperatures from -150 to +150 degrees and can neither be frozen nor destroyed. In the scientific world, there is a view that mushrooms are the main civilization on the earth, and they use everything around them for their own (and us, human) purposes. Mushrooms are white, tasteless, and have a cheesy smell from the nose, mouth, wounds, urethra, etc.Mushroomis ​​the white coating of tongue, baldness and dandruff, atopic dermatitis, and psoriasis. If there are white deposits on the tonsils, this is a fungal sore throat. Mushrooms are not painful and itchy. Mushrooms are all things that flake off, fall off, fall off, crack, rise above the skin, change color, and cover the scalp. Mycosis has no acute phase, only chronic disease.

2. Viruses.

Virusesare non-cellular organisms. They are particles composed of nucleic acids-carriers of genetic information (RNA and/or DNA), covered by a protein membrane. Viruses can infect any living thing.Virus, derived from Latin (virus), is poisonous. The virus cannot be attributed to animals or plants. They are so small that they can only be studied with an electron microscope. Viruses can only survive and develop in the cells of other organisms. Viruses cannot live on the outside of biological organisms. Many viruses behave like chemical substances in the external environment, in crystal form. When viruses enter the cells of animals and plants, they can cause many dangerous diseases. Human viral diseases include:herpes, measles, influenza, HIV, hepatitis, polio, smallpox.

3. The simplest parasite.

Parasitic protozoa-Amoeba, Lamblia, Toxoplasma, Cryptosporidiumand Plasmodium, Malaria, Leishmania, Trypanosoma. Among parasitic protozoa, the most dangerous pathogens of animal and human diseases are known, especially in tropical areas (malaria, dysentery). Plasmodium malaria infects human red blood cells and causes severe fever and death during the mass reproduction stage. Trypanosoma flagellum and Leishmania are mainly tropical species that feed on animal tissues and cause ulcers, discomfort and in some cases death. Rhizobia Rhizobium bacteria live in the intestine and are the pathogen of chronic amoebic dysentery, which can penetrate into other tissues and kill the host. Giardia, a flagellated intestinal parasite, causes severe diarrhea (giardiasis). In subtropical and tropical regions, the species has been found in rivers and lakes polluted by human excrement. Some parasites, such as Pneumocystis carinii, which causes pneumonia, may be closer to fungi than other protozoa.

4. Worms (worms, worms)

More than 70 worms have been registered, of which the following worms are more common:

• roundworm (nematode)-roundworm, pinworm, whipworm, trichinella, toxoplasma;
• tapeworm (cestodes)-Pork and cattle tapeworm, dwarf tapeworm, Echinococcus occidentalis, Pneumococcus, wide tapeworm;
• Flatworms (flukes)-Aspirin caterpillars (cat fe), liver flukes, trematodes, lung flukes.

Some of these parasites are ubiquitous and more common in some areas. E. g:

• pin worms and round wormscan be found all over the world.
• Whipworm-It can be seen everywhere, mainly in tropical, subtropical and temperate climates.
• Trichinella-in Belarus, Ukraine.
• Pork tapeworm-There are records everywhere, and it is more common in Belarus and Ukraine.
• Cow tapeworm-You can see it everywhere. Especially in Transcaucasia and Central Asia.
• Dwarf tapeworm-It can be seen everywhere, especially in dry and hot areas.
• A wide range of worms-Usually choose habitats in areas with a lot of fresh water. Constantly appearing in the Baltic Sea, Kazakhstan.
• Wrist caterpillarosis(Cat flukes)-The most densely affected area is Kazakhstan.
• Liver fluke-everywhere. Outbreaks have been recorded in the Trans-Caucasus, Central Asia and the Baltic regions.
• Hydatid disease, pneumococcal disease-in Moldova in southern Ukraine, in the Caucasus.

There are more than 150 kinds of these parasites, but the most common are "only" about 35 species. According to the location of the parasite in the human body, these diseases can be divided into tissues and cavities.

Organize parasites.

If the parasite and its larvae are in human tissues, in the subcutaneous tissues, they move freely through the circulatory system or lymphatic system. This disease is called tissue disease (schistosomiasis, echinococcosis).

Translucent parasites.

(tape bug, round bug).

Parasites are also distinguished by their specific location (habitat) on the host.

External parasites.

This species parasitizes on human skin directly from the outside. They do not live in the host body, but only use when foraging (mosquitoes, fleas, ticks, lice, horse flies, wasps, water). . .

Internal parasites (worms, worms, bacteria, fungi).

This type of parasite has the following classifications:

• Flatworms (flukes)Bilaterally symmetrical free organisms or parasites in structure. The length of the fluke varies from 0. 1 mm to several meters. Most of the body structure is flat, oval-shaped and more or less elongated; it is parasitic equipped with suckers, proboscis, hooks, etc. "Host" connected organ. The representative of flatworms is turbellaria or ciliates. Aspirin caterpillar (cat fluke), plane worm, liver fluke, bronchus, fasciitis, schistosoma, paragonimi
• Round worms (nematodes), this kind of free parasites live in salt and fresh water bodies and soil. In most cases, their size is small or even small, but there are also very large individuals among parasite individuals, and they are more than 7 meters in length (cete worm). The most common representatives of human parasites roundworms are roundworms, pinworms, whipworms, filariasis, hard caterpillars, hookworms, Trichinella spiralis, Toxoplasma gondii, and Listaria.
• Tape worm (ces worm, tape worm),This type of worm is characterized by long strips (ranging from a few millimeters to tens of meters). Cestodes (Cestodes)-a slender, ribbon-like worm consisting of a head, neck and various parts. It is known for its great fertility (some species can produce up to 600 million eggs per year)-pork and cattle tapeInsects, Dwarf tapeworm-Cyclophyllin sequence; Echinococcus oc, Pneumococcus, Broad tapeworm, sheep brain.
• Bacterial disease. Bacterial disease is an infectious disease caused by various types of bacteria and parasites.
  Bacterial disease is a fairly common diagnosis worldwide. Some bacteria are caused by one type of bacteria, and other bacteria are caused by several types of bacteria. Representatives of this type of parasites are Leptospira, Staphylococcus, Streptococcus, and Shigella.
• Mycosis-Diseases caused by parasitic fungi. More than 350 pathogenic fungi have been identified; they are parasitic on humans, domestic and wild animals, birds, insects, amphibians, fish and plants. The most famous pathogens of mycosis are Candida, Cryptococcus, and Penicillium.
• Protozoa or protozoan parasitesare single-celled organisms with heterotrophic nutrition, that is, they cannot produce organic substances necessary for their life activities from inorganic substances. As a result, they need organic substances produced by other organisms (Amoeba, Lamberia, Coccus, Trichomonas).

The unfortunate fact about worms and other parasites:

• Chronic, including tumor diseases80% of the cases are caused by the influence of parasites (worms, fungi, protozoa).
• Causes of pneumothoraxbelong to the first category of carcinogens (carcinogens), according to the International Agency for Research on Cancer (IARC).
• For humans, the greatest enemy in biology is Trichomonas.Trichomonas causes the development of atherosclerosis by forming colonies on the walls of blood vessels and brings all consequences.
• 1989-It was discovered that the nature of Trichomonas can transform ordinary cells into malignant cells.
According to statistics from the World Health Organization (WHO), parasitic diseases worldwide have affected more than 4. 5 billion people, of which nine out of ten are worms.Every third of Europe's residents are affected by parasites (including worms)!

The frequency of parasites is comparable to that of influenza.

Therefore, there are several ways for parasites to enter the human body:

• Diet-lack of personal hygiene(through contaminated food, water, dirty hands);
• Contact with the family-create external conditions for the active development of parasites(infect family members and pets through daily necessities);
• Can be transmitted-no precautions(through blood-sucking insects);
• percutaneous or active-non-compliance with safety measures(when swimming in open water, the larvae of parasites penetrate the skin or mucous membranes and enter the human body when they come into contact with contaminated soil).
