The human body is constantly exposed to external dangers. This is a different type of disease, infection and so on. One of the most common and serious problems is parasites. They enter the body completely unnoticed, the consequences can be very serious. It is important to know which parasites in the human body are the most dangerous, what health threats they cause. You can see the parasites in detail in the photo.
Different worms live all over the world, all are divided according to the mode of transmission, type. Parasitic worms are transmitted to humans mainly in the following ways:
- infected person;
- animals;
- soil, food, water;
- insect bites.
Worms are divided into several types:
hiccups- ;
- round;
- tape.
Worms are a very large class of parasitic worms that live on plants, animals and humans. They can live in hollow organs, thicker tissues, the tissues themselves.
The 10 most dangerous parasites in the human body
- Schistosomes are dangerous parasites in tropical waters.
- Rishta is a worm that lives under human skin.
- Filariae are dangerous parasites of elephantiasis.
- Echinococcus are dangerous larvae in the body.
- Whiskered Vandellia is a fish parasite.
- Roundworms are known to all worms.
- The bovine tapeworm is a very large and long worm.
- Ankylostoma is a small, harmful worm.
- Broad tapeworm - danger to human intestines.
- Swine tapeworm is a dangerous disease.
Schistosomes - living in venous blood
The parasite's second name is blood chance. The infection occurs through the skin, contact with contaminated water. The disease caused by schistosomiasis is called schistosomiasis.
They differ from other helminths in their habitat: they live and multiply in the venous system. Most common in South America, Africa, the Middle East and Southeast Asia. They are not big in size, length of 2, 6 cm, diameter of 0, 6 mm, which is clearly visible in the photo. A person realizes that he or she is infected with the following symptoms:
- ;
- enlarged lymph nodes, spleen.
But the symptoms are different, everything depends on the location of the body where schistosomiasis accumulated:
- nervous system - disorientation, memory loss, headache;
- bladder - inflammation of organs, blood in the urine, abdominal pain;
- liver - ascites, enlarged organ, spleen;
- intestines - diarrhea, polyps.
Worm eggs are very dangerous, they pierce, damage the walls of the lymphatic and blood vessels of various organs and tissues. In this way, parasites can even enter the uterus, lungs, prostate and stomach. Worms, eggs clog blood vessels, which leads to the formation of varicose veins, tumors, cysts. Helminths of this type can cause serious problems, including cancer of the bladder, liver, prostate and liver fibrosis. To avoid infection with the most dangerous parasites in the human body, it is very important to avoid swimming in tropical waters, washing vegetables, fruits and hands thoroughly before eating. Schistosomiasis can be cured conservatively, if treatment is started in time. In case of complications, operations are performed.
Rishta - subcutaneous worm
Dracunculiasis is a disease caused by this type of parasite in the human body. Infection occurs through dirty water from tropical reservoirs in Asia and Africa. Usually humans are infected, but there are cases of infected dogs.
The worm enters the human body when swallowing contaminated water, where the copepods - carriers of the rishta larvae - live. Treatment by surgery only. Secondary infection of already injured skin is very dangerous.
Once in the body, the rishta literally gnaws at the tissues, the intestinal walls, lives in the lymphatic vessels, the subcutaneous fat. In length, the worm can grow a lot, up to 80 centimeters. Strong abscesses appear in the areas of the body where the rishta are located, and parasites can be found within them. The disease is caused only by females, males die after mating. When an infected area of the skin comes into contact with water, the female worm comes out a short distance and throws its larvae into the water. These larvae must be captured by copepod crayfish to survive.
Filariae is a very dangerous parasite for the body
Another name for the worm is filamentous. Of all the species, about 10 prefer people, which lead to filariasis. They were called wire because of the appearance, the worms are very thin, like a wire, you can see in the photo. 0, 3 cm in diameter, however, they grow in length, up to 50 cm or more. Having reached the body, they live in the subcutaneous tissue, body cavity, heart, blood, lymphatic vessels, any part of the body. Very common in hot countries.
They are transmitted through blood-sucking insects, sometimes ticks, which in turn are infected by the blood of an infected, human animal. The danger lies in the fact that the most terrible worms can be detected when the disease becomes chronic, it is almost impossible to cure it. Accumulating, the filarias block the lymphatic system, block blood vessels, causing elephantiasis. The patient's legs get big, swell too much, even if it is impossible to move, there are many pictures of people with this disease on the internet.
The echinococcus is a great danger to humans and animals
This tapeworm lives in the intestines of dogs, wolves, rarely cats and can easily be transmitted to humans.
Echinococcus larvae are one of the most dangerous, causing echinococcosis. An adult worm is 3 to 5 mm long, in the photo that describes the parasite it is very visible that it has a head with suction cups, hooks and segments. Eggs and feces come out of the canine's body, sometimes getting into the wool.
Infection is also possible through cattle. The infection occurs in humans through the mouth, eating contaminated meat, dog saliva. Larvae penetrate the body even more, through the blood they enter the liver, where they live and multiply. It rarely enters the bones, muscles, lungs. During development, echinococci turn into large bubbles the size of a child's head. Depending on the disregard of the disease, the treatment is done with medication or promptly, removing the tissues of the organ along with the bubbles of the larvae.
Whiskered Vandellia - the smallest and most terrible
In general, this creature belongs to fish, but it is one of the most dangerous for the body. People are afraid of it because, during the bath, a small, almost transparent 15 cm long creature can easily penetrate the urethra, genitals and anus. Then, Vandellia is attached to the vessels and feeds on blood. Unfortunately, the only way to get rid of the parasite is through surgery.
Ascaris - the most famous worm in the human body
The parasite is common, often found in the human body. If the eggs of a human roundworm fall to the ground, they can be stored there for almost a year until they move into a favorable environment. In the body, it releases toxins that affect the liver and lungs. Ascaris does not stop in one place, travels constantly throughout the body, affects blood vessels and causes inflammation.
The main place of life of the most harmful worm is the intestine, where the parasites live comfortably, eating the food that the infected person eats. They can pass to the pancreas, bile, liver, reach the esophagus, block breathing. A worm lays up to 1000 eggs a day. They grow a lot in length, up to 30 cm.
The bull tapeworm is the largest and most dangerous worm
This very large parasite lives in the small intestine. The tapeworm photos are just incredible. The body of the tapeworm consists of a head with suction cups, a large number of segments, ranging from 2, 000 to 5, 000. The worm's length constantly increases with growth, up to 10 meters. In the human body, without treatment, it can live up to 20 years. It produces about 600 million eggs per year, up to 11 billion per life cycle.
Lives only in the small intestine of an animal, a human. The intermediate host by which a person is infected is cattle. Infection occurs through poorly processed, cooked or raw meat, milk, fish, contact with pets.
Hookworm - a harmful and dangerous worm
The worm is very common in East Asia, Africa, causes hookworm disease. The parasite lives in the human duodenum, does not grow much, at most 14 mm. The infection occurs through dirty hands, vegetables, fruits, even through the skin when working with the soil, when walking barefoot in the grass, the larvae penetrate the skin.
Once in the body, it enters the blood vessels, from there it goes to the liver, heart, lungs. Ankylostomosis leads to serious complications, in particular hepatitis and ulcers.
Wide ribbon - a dangerous parasite with a large, long body
Infection with this worm occurs through fish, if a person has eaten undercooked raw fish, raw pike caviar or has been involved in processing infected fish, seafood.
A dangerous tapeworm grows up to 15 meters in length, is very large, the body is made up of a large number of segments - up to 4, 000, on the head there are suction cups with which the worm clings to the intestines. Looking at the photo of the worm, it is simply difficult to believe that it can live inside a person. The larva develops in just one month. The broad tapeworm leads to a serious disease - diphyllobotriasis.
The patient has a strong vitamin deficiency, because the worm feeds on all the nutrients in the body. Your entire large body absorbs substances on its surface. At the spot where the tapeworm was sucked, necrosis begins. The most dangerous tapeworm can live in the human body for up to 10 years.
Pork tapeworm is a very harmful worm to the human body
This worm can be mistaken for a bovine tapeworm, but it does not grow as much, being at most 3 meters long. There are also fewer segments on the body, up to 1, 000. On the worm's head there are suckers, a trunk with hooks. Thus, the tapeworm is attached to the intestinal walls. It takes root in the body of pigs, rabbits, hares, dogs, camels, where it reaches the person - the final owner. Infection is allowed through the use of raw bacon, meat. It is very dangerous for eggs to enter the human body, as it becomes an intermediate master, in which the Finnish phase occurs, which often leads to the most serious diseases and death.
Helminths cause diseases of cysticercosis, teniasis. If there are many parasites, they obstruct the intestines, so the patient needs to be operated on urgently. They can pierce the intestinal walls, enter the lymphatic vessels and enter the internal organs. Complications of diseases cause damage to subcutaneous tissue, muscles, skin, spinal cord, brain, bones and internal organs. The most important thing is to do the prevention, to carefully process the meat before eating. The person must observe personal hygiene, prevention of helminthiasis.
