Helminthiasis at the people when entering the body, one of the 300 types of parasites. At the same time, the Patient can be master of 1 up to 5 different worms. You need to know what types of tape worms in humans are most common, how they look, how the infection takes place.
The fear of viruses, worms, leads to the fact that patients tend to think that it is worms guilty in any deterioration. Helminths – representatives of the invertebrate animals, the extremely primitive structure. You can't exist completely outside the body of the host, since the nutrients are preserved and the conditions for the active breeding.
You should list what worms there are in humans. Cause disease: round, flat and tape worms.
The most common types of tapeworms found in humans:
Among all the worms and parasites in humans, the most common type of pinworms (or Enterobius vermicularis) are. These small round worms with a translucent body and white color. Pinworms separated floors, the reach males 4-6 mm, females 10 mm. Worms are ubiquitous and cause enterobiasis. It is more common in children.
Pinworms spread from person-to-person by ingestion of eggs or the infestation through the Anus. The entire life cycle of the worm in the Lumen of the intestine. In the process of movement from the eggs, larvae, and grow in a supportive environment. In the colon, individuals wedding flight copulate, then. The females proceed with the peristalsis of the rectum and in the night hours to lay their eggs in the perianal Region. Then you will perish and the sick can see people in underwear or toilet paper. If you carefully examine what looks like worms in humans, compared to you can worm with small translucent.
The eggs are in the environment, where the spread of the disease among other people, or repeated self-infection
On the note! Pinworms are on the Laundry, household items, animal hair, food. The eggs outside of the human body retain their viability for up to 2-3 weeks.
Thread Worm – Type Round Worms. Individuals separated floors. Live nematode red worms fusiform shape. The body length of females is up to 40 cm, males up to 20 cm thick, vermin – up to 6 mm. Dead parasites a whitish hue, translucent. When you see the photos of worms roundworms, you will notice that the females have a direct the body, and the males curved, on the one hand.
On the note! The mating and the egg laying takes place in the intestinal lumen. So an individual per day can be up to 200 thousand eggs with a thick shell. It protects individuals, the negative effects of the environment. The larvae Mature in soil in 2-3 weeks. The further development of the animals is only the penetration in the intestine of the host.
The infection with these parasites occurs through contact with the sick Person, the consumption of unwashed vegetables, berries or herbs. Mechanism – fecal-oral route. The man is the main host of Ascaris lumbricoides.
Swallowed them into the stomach, then in 12 duodenal ulcer are invasive eggs of the worm. There, the parasites come out, and by damaging the mucosa of the organ fall within the small vessels of the digestive system. Then the worms are distributed in the portal vein, and outflow of blood to the internal organs: liver, heart, lung. In the respiratory system worms, to cause to rise to the Oropharynx and cough. Roundworms move to the internal organs – Phase of the Migration of the parasite.
If swallowed with the saliva or cough of worms tract are in the Lumen of the digestive. The intestinal Phase of the worm.
On the note! The entire life cycle of Ascaris lumbricoides takes about 60-70 days. The eggs of the worm in the soil is stored up to several years.
This geohelminth is only found in humans. The infection occurs through the consumption of vegetables or fruit, water containing the eggs of the parasite.
Externally, the worm is reminiscent of the long hair with a thickened rear part. The size of the body of the parasite is up to 5 cm These worms in the human body lives in the intestine and lay up to 10,000 eggs per day. The parasite life expectancy is 4-6 years.
Descendants of whip worms in with the feces into the environment, and Matures in the earth. Externally, the eggs resemble translucent barrels with cover at the poles. After infection with the whipworm of humans from the shell and freed in a couple of weeks to Mature.
The most important hosts of this parasite are cats and dogs.
In the case of parasites, there are species with male and female sex. You can reach 10-20 cm long, the thickness of the body up to 3 mm. Externally, these worms look like thin threads of white color. Their life expectancy is 5-6 months.
The owner of a pet can notice that your pet is in Calais after defecation or planned degelmintizatsija. Live parasites have a slightly yellowish hue, and is very fertile. Each female inside the body of the primary host, lays up to 150 million eggs per day. The eggs with thick nubby sleeve to fall in the environment, and tires to the state of the invasive within 1-5 weeks.
The infection occurs through contact with soil, consumption of berries, vegetables without a thorough washing. In the group of the risk, the people living in rural areas. The eggs of Toxocara will fall in the digestive tract of the people. The larvae of the worms will come out of the shell and penetrate the skin in the intestinal mucosa. Your migrating roundworms move reminds.
On the note! However, these types of worms in humans are through complete development cycle, you will be so deposited in the body through the blood and in the internal organs. Worms acquire a connective tissue capsule and can for a long time in an inactive state. Suspect toxocariasis in children or adults is extremely difficult. The person-to-person is not possible.
These round worms that live in muscle tissue and the intestinal lumen. You are trichinosis, the cause of the deadly disease.
Trichinella spiralis is found everywhere, with the tendency to natural about fokalität in the woods. It is with the wide spread of the disease in certain animal species. Trichinella separate floors, their description is as follows: individuals, Yes, 3-4 mm long, the body of the worm is elongated, sharp at one end.
Host of the parasite can be animal or human. The disease in humans occurs when eating infected meat, the larvae of the worm (often pig meat). Life cycle of Trichinella is carried out within a host, without the environment for the maturation of the larva:
Trematodes (or flukes) is a flat worms. There are more than 7000 species of these parasites, the diseases in humans, only 40 cause of them. Due to their localization in the human body, you distinguish the following types of worms-fasciola:
The most common worms – Fasciola hepatica, Opisthorchis felineus, Schistosoma haematobium. Most of the species of fasciola prevalent almost everywhere, only Schistosoma inhabit mainly in countries in Asia, Africa and South America.
For these worms, characteristic of the development is a change of owner and the alternating free-living and parasitic stages. Most of them lives in front of the meeting with the Person in the housings of the mollusc, of the fish. Without the body of the intermediate host, the worms are free-floating in the water. Subsequently, the infection of parasites of larger animals – cats, cattle, and calves. In the case of schistosomiasis, one is the master of the worm, when the penetration of the latter by healthy skin during bathing.
In other cases, the between Pets can be hosts. They swallow worms, to drink, to the consumption of infected larvae of the grass.
Dimensions fasciola differ depending on its type – from a few millimeters to tens of centimeters. The body of the worms with a flattened shape is reminiscent of a leaf or suppositories. The head end of the parasite with a plurality of suction cups for mounting inside the body of the host. These worms have a primitive internal structure. Their organ systems are developed, the supply and reproduction of your same.
On the note! The shell of the eggs of fasciola on the one hand, thickened, and the operculum. This distinctive shape allows the diagnosis of the disease in humans.
Tape worms (or cestody) – the longest worms. In the intestine of humans is one of the 5 types of helminths could settle. Their names point to the extent that the origin of the larvae.
These parasites have flattened a long body, consisting of repetitive segments. Front-End-hook ends with the "head" with the characteristic organs of attachment. In degelmintizatsija worms can go. Patients describe the individual segments of hook, such as the white formation, similar to Fig.
The internal structure of such worms is extremely primitive: the majority of them, the digestive system is missing even, nervous and weak. This circumstance does not prevent you widely used because of their sexual system consists of the organs in any part of the body and ensures a high level of fertility.
On the note! The worst representative hooks hold a wide lentetsa, which can be up to 25 m in length. Dwarfish tsepen – the smallest of this group of parasites. Its length of not more than 5 cm.
The life of an individual can be large enough. So swine tsepen alone occupied the intestine and is located in the human body for up to 20 years.
The hosts hook at different stages of development of the basin, the cattle, vertebrate inhabitants of the water, and molluscs. The infection occurs by eating inadequately cooked or roasted meat, fish. Wormser hit various internal organs, can cause serious complications.
These small worms-solo-traducitur-ranking helminths, in 12-perstnoj intestines of humans. In the case of infection of helminths in the intestinal wall, destroy your digestive enzymes.
The most common types:
Hookworm are ubiquitous, but mostly in the countries of North and South America, India, China, South Europe.
The size of these worms is not greater than 14 mm – Ancylostoma duodenale or 11 mm Necator americanus. Individuals separated floors. After mating, they lay their eggs in the Lumen of the intestine.
The larvae together with the kalovymi masses get into the environment, where they ripen. It is in the ground within 1-2 weeks from the eggs, new individuals are created by the Phase of the non-invasive or non-contagious, and filariidae (invasive) larvae.
Filariidae larvae are able to remain alive and ready to penetrate the human body within 8 weeks. The largest concentration of these worms in the soil in warm and humid climates, pollution of the environment by faeces.
On the note! Most frequently, outbreak of the disease in the field of mines, or mines. The infection occurs through the intact skin when walking barefoot.
Necator americanus or hookworm in the New world by the characteristic bend of the end, has a pale-pink hue. This parasite causes the disease necatoroz.
The human worms Ancylostoma duodenale look like small, thin worms in the color white. They cause the development in hookworm ("Egyptian scabies" or "rash of the mountain people").
The analysis of the different types of worms, not to say that some of them are really a danger to humans and other value. In the case of suspected infection, parasites, you should immediately consult a doctor and check can.
