Parasic organisms can be found in almost every living being.In most people, they cause nothing but disgust and fear, which is not surprising, because sometimes these babies cause terrible diseases.We bring to your attention the 25 most terrible and dangerous parasites
Parasitism in nature is very widespread.There are parasites, insects of parasites, worms of parasites, parasitic plants, etc.There are so many of them that even some parasites have their own - and they can be the most bloodthirsty in any sense.A striking example of this "army of darkness" is the malaria plasmodium, which parasitizes in a malaria mosquito (which in turn is a temporary parasite of warm animals and humans).This unicellular organism finds almost one -third of a billion new casualties every year and kills more than a million.
Sakulina
This Aegent crustaceans parasite the crab.He literally germinates throughout the owner's body, sucking nutritional juices from him.Cancer gradually weakens and even loses its ability to regenerate.When it comes time to multiply for the parasite, it gives special chemicals in the blood of crabs, under the influence of which female crabs begin to take care of the eggs of the parasites as their own.A crab wizard affected by the parasite refuses mating, and instead, under the influence of chemical doping, takes care of parasitic eggs in the same way as the female.
Cordyceps is one
This tropical sponge parasitizes on ants.He is also known for being able to control the owner's behavior.When the fungus multiplies, it gives the chemical team to the ant and it obediently climbs the upper leaves of the plants and retains immobility, allowing the sponge to completely germinate through its body, open the hat and release disputes into the air.
Anisakidi
One risks infecting these worms, eating poorly processed sea fish, shrimp, squid or octopuses, poorly treated by them.For the first time, anisakidosis infection was reported in 1955 in the Netherlands and the source is a slightly salted herring.If, by cutting the fish, you see in its muscle tissue, on caviar or milk "some spirals" -or relentlessly throw away delicacy, or freeze the fish to -20 degrees and keep yourself in this condition for at least two weeks.With this treatment, the worms and their microscopic larvae will die.The fish can then be safely eaten - however, the awareness that it does not cause a "worm" appetite.
Wolkachia
These bacteria are intracellular parasites of many insects and worms.By spreading into the body of the host, the bacteria manage to "attach" their own to their gene.For example, the genome of some flies-crusophile also contains an almost complete copy of Wolbachia's genome.
Sand fleas
Sand fleas are a very dangerous parasite that affects pets, rodents, monkeys and people.Its big distribution is a real problem for countries such as Nigeria, Todago and even Brazil.In non -functional areas, the number of people suffering from this parasite can reach 70%.For some reason, sand fleas prefer sand fleas.When human infection with these parasites, the microscopic female flea is introduced into the skin of the feet or under the nails.Just 5-6 days after the introduction, the female belly, filled with eggs, grows to the size of the pea, causing painful pain for the owner.When the eggs ripen, the female "shoots" them into the environment, after which it crawls from the wound, but much more often dies directly into the human body.
OSA Hymenoepimecis Argyraphaga
OSA parasites mainly on spiders.After temporarily paralyzing her victim, washing attaches her egg to her breasts.Soon the spider reaches its senses and continues its life.The developing larva gradually sucks the juices from it and before the bowl it injects a special chemical into a spider, under the influence of which, instead of a conventional network, it builds a special cocoon where the larva transforms into concrete for adults.
Vandelia candidate
In fact, this small translucent fish parasitizes in the gills of other fish living in the Amazon rivers.But in search of the victim, the candidate focuses on the smell of ammonia contained in the water that has passed through the gills.This makes her extremely dangerous for a person.If a person is in the water, then he or she has learned a chemical signal, the candidate is introduced slightly into the anus or into the urethra of a person, sometimes even reaches the bladder.After penetrating the body, the candidate inevitably dies, but the injury he manages to apply is just a terrible and only good surgeon can extract his dead body covered with stubborn spikes.
Trichomonade
Trichomonas is a unicellular flaglied microorganism.Some types of trichomons are completely safe, but there are real killers.In birds, these parasites can cause severe inflammation in the mouth and throat, resulting in the bird cannot swallow and eventually dies.Another type of trichomonas (vaginal trichomonia) parasitizes in the genital organs of a person and causes a serious disease of the trichomoniasis, which is today the most common disease of the Earth's genital tract.Medical statistics say that almost every tenth resident of the planet suffers from this disease.
Leishmania
It is a whole cereal culture of the simplest organisms that cause serious illnesses called leishmaniasis.For example, leashmaniasis of the skin, manifested in the form of painful abscesses, causes Leishmania, first parasitizing mosquitoes and flies, and then on warm animals, including humans.Initially, the parasites are multiplied in the digestive channel of the blood, which is of the insect that it is completely blocked.Biting a person, the insect first numbs a lump of parasites into the wound and then sucks blood.Lishmaniasis is very common in tropical countries and about two million new cases of diseases are registered every year in the world.
Mokritsa absorbing language (Cymothooa Exigua)
Fortunately, for a person, this crustacean is completely safe.Mokritsa attaches to the tongue of the fish and first sucks the blood from it.When the fish tongue dies, the well -fixed parasite itself begins to play the role of a special prosthesis of the tongue, eating blood and mucus of the fish, but not cause it to special damage.
Tripanosoma
A kind of very dangerous unicellular organisms parasitizing on insects and warm radiation animals.So, triatomic bugs are the carriers of Trypanosoma Cruzi Tripanos, which cause human disease in a person.The disease affects the whole body and quickly leads to death.
Toxoplasm
The simplest microorganisms that cause serious illness are toxoplasmosis.The main owners of the parasite are cats, people and other warm, stewed acts in the role of intermediate hosts.Often toxoplasmosis can occur very easily, disguised as a common cold.But by reducing immunity, the disease can lead to madness, convulsions, paralysis and other lesions of the nervous system.Toxoplasmosis for pregnant women is particularly dangerous as it leads to the death of the child before birth.
Cochliomyia hominivorax flies from flies
The women of this fly living in America are inconspicuously attaching eggs to the body of warmly attached animals.The larvae that have come out of the eggs are introduced under the skin that care for the body of the victim of whole holes.These types of flies that lay eggs in the eyes and nose are particularly dangerous.In this case, the larvae that absorb the flesh of the owner can cause blindness and even reach the brain.There are cases where doctors extract more than 150 larvae from the nasopharynx of a person affected by this parasite.
Hairy
Very ancient waterworms, the larvae, of which parasitize several types of insects - water horses, elevators, beetles and more.Adult worms break the owner's body and return to the tank where they spread.
Philaaria
In public, almost 10 different types of Philius are parasitized.These extremely thin worms (their diameter does not exceed 0.3 mm) can reach a length of almost half a meter.Filaar distributors are blood insects.In the human body, worms can live almost anywhere.When they block the lymphatic system, ivory develops and if it accumulates in the eyes, then one can blind.
Loa Loa
The thin round worm Loa Loa belongs to the Eagles and is very common in West and Central Africa.The parasite of the blind and other blood inhabiting insects spread.Adult worms live under the skin.The females immediately produce live larvae, which accumulate to the light and peripheral blood vessels, causing various tumors and inflammatory reactions.The worms are constantly migrating through the body and if they get into the eyes, it can lead to blindness.
Clostridia Perfringens
The Clostridium Perfringens bacterium can cause severe nutritional poisoning as well as cause the rapid development of a gas gangrene, in which the tissue affected by the bacterium literally solutions secretes gas bubbles.
Schistosoma
First, the larvae of this worm develop in freshwater molluscs, then they enter the water and attack mammals, introducing under the skin.The schistosomes spread throughout the body and are particularly dangerous when they accumulate in the bladder and genitals.Shistosomatoz is difficult, has many heterogeneous symptoms and causes great suffering.The parasite is common in Africa, China, Philippines and Indonesia.
River blindness
River blindness or onchocecosis are caused by Ontchocerca Volvulus Filaria.The carrier of these parasites is Simulium Damnosum, widespread on the rivers of West and Central Africa.Worms of this species and their larvae especially affect the eyes, leading to complete loss of vision.
Meningococcus
Neisseria meningitidis bacteria parasitize in the nasopharynx of many people.Unfortunately, they are able to cause not only severe runny nose, but also inflammation of the shells of the brain - meningitis.
Flies tseces
The African fly itself is blood in a temporary parasite.But with a bite, it often infects its victim with a much more dangerous parasite - the type of trypanos that causes a deadly sleepy disease.
Guinean worm
The worm is common in Africa, India and the Arabian Peninsula.Microscopic larvae live in fresh water and when it comes time to attack animals and humans, introducing under the skin.Adult worms can reach 2 mm thick and length 1 m.
Plasmodia
Parasitic unicellular organisms, some species of which can cause malaria.
Foul
This amoeba lives in fresh tanks, the temperature of the water in which it is 25-30 degrees.One is infected during bathing.Damage to these parasites can cause fatal meningitis.Sometimes, when even pools with poor chlorinated water become sources of infection.Such cases are rare, but every time they cause real panic, as visitors to pools, resort thermal springs and baths fall victim to.
Leukochloridia is paradoxical
Paradoxum leucochloridium is a flat worm parasite of snails and birds.Snails are intermediate hosts of the worm.Developing the larva germinates through the body of the snail, and when one of its outgrowths (called sporocitis) reaches the tentacles of the snail, it changes in such a way that it becomes very similar to the green caterpillar.To make its masquerade even more convincing, the larva constantly trembles with growth, mimicking the caterpillar movements.All this was started to get the bird's attention and to force it to steal the caterpillar.In the body of an infected bird, the worm grows into sexual form and lays eggs, which together with the bed of the bird fall to the ground and the cycle of development is repeated.The special "paradoxical" of this parasite is that the snail, who lost the tentacles, usually does not die, but grows a new one.Then the larva, who is in her body, forms a new sporocyte and again lures the birds.
