Parasical organisms can be found in almost any living creature.In most people, they cause nothing but disgust and fear, which is not surprising, because sometimes these babies cause terrible diseases.We present to your attention the 25 most terrible and dangerous parasites
Parasitism in nature is very widespread.There are parasites, parasite insects, parasite worms, parasitic plants, etc.There are so many of them that even some parasites have their own - and these can be the most bloodthirsty in every sense.A striking example of this “army of darkness” is malaria plasmodium, which parasitizes in a malaria mosquito (which in turn is a temporary parasite of warm -blooded animals and humans).This unicellular organism every year finds almost a third of a billion new victims and kills more than a million.
Sakkulina
This eveegent crustacean parasitizes on crab.He literally sprouts through the whole body of the owner, sucking out nutritious juices from him.The crab gradually weakens and even loses its ability to regenerate.When it is time to multiply for the parasite, it gives special chemicals into the blood of a crab, under the influence of which females of crabs begin to take care of the eggs of parasites, as their own.A crab sorcerer affected by the parasite refuses to mating, and instead, under the influence of a chemical dope, takes care of the parasite eggs in the same way as the female.
Cordyceps is one -sided
This tropical fungus parasitizes on ants.He is also famous for being able to control the behavior of the owner.When the fungus comes to multiply, it gives an ant the chemical team, and he obediently climbs onto the upper leaves of the plants and retains immobility, allowing the mushroom to completely germinate through his body, open the hat and release disputes into the air.
Anizakids
A person risks getting infected with these worms, eating a poorly processed sea fish, shrimp, squid or octopuses poorly processed by them.For the first time, infection with anizakidosis was recorded in 1955 in Holland, and the source was a slightly salted herring.If, cutting the fish, you see in its muscle tissue, on the caviar or milk “some spirals” -either ruthlessly throw out the delicacy, or freeze the fish up to -20 degrees and keep in this state for at least two weeks.With this processing, the worms and their microscopic larvae will die.After that, the fish can be safely eaten - however, the consciousness that it does not cause a “worm” appetite.
Volbachia
These bacteria are intracellular parasites of many insects and worms.Propagating in the host’s body, bacteria manage to “attach” their own to his gene.For example, the genome of some flies-crusophile also contains an almost complete copy of the Volbachia genome.
Sand flea
Sand flea is a very dangerous parasite that affects pets, rodents, monkeys and humans.Its great distribution is a real problem for countries such as Nigeria, Todago and even Brazil.In dysfunctional areas, the number of people suffering from this parasite can reach 70%.For some reason, sandy fleas prefer sandy fleas.When human infection with these parasites, the microscopic female flea is introduced into the skin of the legs or under the nails.In just 5-6 days after the introduction, the female abdomen, stuffed with eggs, grows to the size of the pea, causing a painful pain to the owner.When the eggs ripen, the female “shoots” them into the environment, after which she crawls out of the wound, but much more often she dies directly in the human body.
Osa Hymenoepimecis Argyraphaga
Osa parasitizes mainly on spiders.Having temporarily paralyzing his victim, the washing attaches her egg to her chest.Soon the spider comes to his senses and continues his life.The developing larva gradually sucks juices from it, and before pupation it injects a special chemical substance into a spider, under the influence of which, instead of a conventional web, it builds a special cocoon, where the larva makes a transformation into adult concrete.
Vandelia Kandira
Actually, this small translucent fish parasitizes in the gills of other fish living in the Amazon rivers.But in search of the victim, Kandira focuses on the smell of ammonia, which is 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 having learned a chemical signal, the candida is lightly introduced into the anus or in the urethra of a person, sometimes even reaching the bladder.Having penetrated the body, Kandira inevitably dies, but the injury she manages to apply is simply terrible, and only a good surgeon can extract her dead body covered with tenacious spikes.
Trichomonade
Trichomonas is a unicellular flagelled microorganism.Some types of trichomonas are completely safe, but there are real killers.In birds, these parasites can cause severe inflammation in the mouth and throat, as a result of which the bird cannot swallow and, in the end, dies.Another type of trichomonas (vaginal trichomonas) parasitizes in the genitourinary organs a person and causes a serious disease of trichomoniasis, which today is the most common disease of the genitourinary tract on Earth.Medical statistics say that almost every tenth resident of the planet suffers with this disease.
Leishmania
This is a whole cereal of the simplest organisms that cause severe diseases called Leishmaniosis.For example, leashmaniasis of the skin, manifested in the form of painful abscesses, cause Leishmania, parasitizing first on mosquitoes and flies, and then on warm -blooded animals, including humans.At first, parasites multiply in the digestive canal of the blood -sucking insect that it is completely blocked.Biting a person, the insect first burps a lump of parasites into the wound, and then sucks blood.Leishmaniosis is very common in tropical countries, and every year about two million new cases of diseases are recorded in the world.
Mokritsa, devouring tongue (CYMOTHOOA Exigua)
Fortunately, for a person this crustacean is completely safe.Mokritsa attaches to the tongue of fish and first sucks blood from it.When the fish language dies, a well -fixed parasite itself begins to play the role of a peculiar prosthesis of the tongue, eating the blood and mucus of fish, but not causing it to special damage.
Tripanosoma
A kind of very dangerous unicellular organisms parasitizing on insects and warm -blooded animals.So, triathomic bugs are carriers of Trypanosoma Cruzi tripanos, which cause a person’s disease in a person.The disease affects the whole body and quickly leads to death.
Toxoplasm
The simplest microorganisms causing a serious illness are toxoplasmosis.The main owners of the parasite are cats, people and other warm -blooded acts in the role of intermediate hosts.Often, toxoplasmosis can occur very easily, disguised as a common cold.But with a decrease in immunity, the disease can lead to madness, convulsions, paralysis and other lesions of the nervous system.Toxoplasmosis for pregnant women is especially dangerous, as he leads to the death of the child before his birth.
Cochliomyia hominivorax meat flies
Females of this fly, living in America, imperceptibly attach eggs to the body of warm -blooded animals.The larvae that have come out of the eggs are introduced under the skin, gnawing at the victim’s body whole holes.Those types of flies that lay eggs in the eyes and nose are especially dangerous.In this case, larvae, devouring the flesh of the owner, can cause blindness and even reach the brain.There are cases when doctors extracted more than 150 larvae from the nasopharynx of a person affected by this parasite.
Hairy
A very ancient water worm, the larvae of which parasitize on several types of insects - dragonflies, lifts, beetles, etc.Adult worms drill the owner’s body and return to the reservoir, where they are propagated.
Filaria
In public, almost 10 different species of Philius are parasitized.These exceptionally thin worms (their diameter does not exceed 0.3 mm) can reach a length of almost half a meter.Filaria distributors are blood -sucking insects.In the human body, worms can live almost anywhere.When they block the lymphatic system, an ivory develops, and if they accumulate in the eyes, then a person 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 -sucking insects spread.Adult worms live under the skin.Females immediately produce living larvae, which accumulate to the light and peripheral blood vessels, causing various tumors and inflammatory reactions.Worms constantly migrate through the body, and if they fall into the eyes, this can lead to blindness.
Clostridia perfringens
The Clostridium Perfringens bacterium can cause severe food poisoning, as well as be the cause of rapidly developing gas gangrene, in which tissue affected by a bacterium literally dissolve, secreting stench gas bubbles.
Schistosoma
First, the larvae of this worm develop in freshwater mollusks, then they go into the water and attack mammals, introducing under the skin.Schistosomes spread throughout the body and are particularly dangerous when they accumulate in the bladder and genitals.SHISTOSOMATOZ is difficult, has a lot of heterogeneous symptoms and cause great suffering.The parasite is common in Africa, China, the Philippines and Indonesia.
River blindness
River blindness or onhocercosis is caused by Ontchocercerca Volvulus filaria.The carrier of these parasites is Simulium Damnosum, widespread along the rivers of West and Central Africa.Worms of this species and their larvae especially affects the eyes, which leads 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.
Fly Tseces
The African fly in itself is a blood -sucking temporary parasite.But with a bite, it often infects its victim with a much more dangerous parasite - the type of tripanos that cause a deadly sleepy disease.
Guinean worm
The worm is common in Africa, India and on the Arabian Peninsula.Microscopic larvae live in fresh water, and when it comes time to attack animals and people, introducing under the skin.Adult worms can reach 2 mm in thickness and 1 m in length.After mating, the males die, and the females move into the subcutaneous layer, drill the skin, and when a person is in water, they release through the made hole of the larvae.
Plasmodia
Parasitic unicellular organisms, some species of which can cause malaria.
Negleria Fowler
This amoeba lives in fresh reservoirs, the temperature of the water in which is 25-30 degrees.A person is infected during bathing.Damage to these parasites can cause fatal meningitis.Sometimes when even pools with poorly chlorinated water become sources of infection.Such cases are rare, but each time they cause a real panic, since visitors to pools, resort thermal springs and baths become victims.
Leukochloridia is paradoxical
Leucochloridium Paradoxum is a flat worm parasitic on snails and birds.Snails are intermediate hosts of the worm.Developing, the larva sprouts through the body of the snail, and when one of its outgrowths (called sporocyte) reaches the tentacle 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 twitches with outgrowth, imitating the movements of the caterpillar.All this is started in order to attract the attention of the bird and force it to stole the “caterpillar”.In the body of an infected bird, the worm grows into a sexual shape and lays eggs, which, along with the litter of the bird, fall to the ground, and the development cycle is repeated.The special “paradoxical” of this parasite is that the snail, having lost the tentacle, as a rule, does not die, but grows a new one.Then the larva that is in her body forms a new sporocyst and again lures the birds.
