Earthworms in the man is a pathology parasitic genesis, which is often chronic and is accompanied by the participation in the invasive process of the different structures of the human body. Worms in the human body is developed immediately after arriving through the so-called "gateway", and after some time, the length of time that depends exclusively on the type of pathogen.
Almost all the worms are of a single type parasitic. According to the world health organization statistics, the infection of worms in the man is the most common form of injury of state, which take place in the human body.
In tropical countries the most common of the disease, which detect a variety of worms in the stool of a person.
The largest group of this pathology are worms that affect the organs of the gastrointestinal tract, and in the second place by the frequency of repetition are worms, which can affect the gallstones of the route. It is very rare the presence of earthworms in the man lung parenchyma, and the organs of the lymphatic system.
The distribution of the worms may occur in a variety of forms, from egg to adult.
For the means of life of the worms, belong to a special group of parasites, it is indispensable the presence of a fact of change of masters. Worms, belong to the category of geo-helminths, differ in that their larval stage is developed in the natural conditions of the environment.
Worms in the human body are often sporadic.
The eggs of the worms in the man can produce in the intestinal lumen, as well as in other structures (liver and the lung parenchyma). Tape worm in man, is logged is extremely rare and represents only 5% of all worm invasions. The infection of worms of the adult occurs almost by the same mechanisms that in children.
The clinical manifestations of the presence of worms in human can vary over a wide limit, which depends on the species of parasite. And yet, the presence of earthworms in the man, is always accompanied by the special call of a syndrome characteristic of all types of invasion.
About "how to draw worms in humans", can refer to any of Parasitology, and the patient should use an anti-parasitic treatment under medical supervision. Prevention antiparasitic activities must, first of all, it will consist in the application of off-target effects of measures for the correction of habits of hygiene.
Pinworms in man are found in different patogenticos of variants, from the specificity of which depends on the clinical symptomatology. In the environment gathers a huge amount of worms, however, not all of them are pathogenic for man.
Worms are distinguished by the fact that you can not long preserve the signs of life without the master. The infection of worms in the human body occurs through the oral cavity and of the epidermis. Each one of the species of worm invasion of different originality income of the worms in the body perceptive.
The speed of propagation of worms depends directly on the weather conditions. Thus, the favorable weather condition for the maturation of worm invasion of the human is one of the conditions of high humidity and high air temperature. In the process of propagation of the worms in the people of good level, with the socio-economic level of the population. So, it is very high rate of worm invasion of the population is observed in countries with low hygiene standard products.
The development of the worms in the man is produced by various methods of infection. Ostritsy are the most common of the worm occurs an invasion of the person, and the parasite is a small round worms grayish-white color that is introduced in the body of the person eggs mainly by the oral route, and through, that is to say, through the mouth. Chronic during the earthworm the person to the worm invasion is often samsarajade. The species adult ostritsy mature in an average of two weeks with a migration process in the lower part of the division of the small intestine.
The larvae stage of the worms secret enzymes, whose action is directed to the destruction of the intestinal wall, accompanied by local inflammatory process. Earthworms in the man, the promoters of development enterobiasis, have exclusively the mechanical stress on the intestinal wall, accompanied by the education of a multitude of small bleeding erosions.
Worm invasion of the human cause round worms, which can reach very large size. The beginning of the clinical manifestations of the worm of the invasion begins with the contact of the eggs in the intestine, with the subsequent entry of the larvae in the flow of the circulating blood. Final location of larvae of Ascaris is the lung parenchyma. The ascariasis accompanied by the development of a severe allergic reaction resulting from exposure to the products of the vital activity of the worms.
Another of the worm invasion is the impact on the human body digestive specific form of worm, whipworm, has expanded, the shape and small adjustments.
The specific of the tape worm of man lentets the choice can become colossally large. The spread of the individual data worm occurs by ingestion of contaminated foods of fish. The eggs of the worms in the man are eliminated with the feces are not immediately after infection, and only after 25 days.
Trichinella adults are different triggers the production of eggs, mass entering the small intestine, where it produces its maturation with the monitoring of the concentration in the skeletal muscles.
Strong worm invasion develops after exposure larval stage liver Fluke in bile ducts. The kind of adult liver Fluke does not differ large size. Swine tsepen the man parasitizes mainly in the small intestine, and the maturation of the species adult takes not less than three months.
The main difference of equinococo other worms infecting humans, is that the disease are not the adults of the species, and the finns. Intermediate teacher for a cyst hidatídico is the dog and the man is infected with worms, in this situation of contact with the method. The primary location of the eggs by a cyst hidatídico is the intestine, where it is transformed into oncospheres, which may spread through the body, finally concentrating in the liver and the lungs.
The infection of worms in the human body, as well as to the clinical onset of symptoms, normally, is of special during. Acute period of the current worm invasion of the man can last for up to two months, while more long-term symptoms involves chronic of the pathological processes whose duration is of several years.
The debut of evolution to acute, earthworms to the person can be observed from the moment of contact of worm in the body and continues along all the time, when the human body is activated and produces an immune response in response to the introduction of exotic species of antigens, which clinically manifests an intense allergic reaction. The acute phase of worm invasion of the man is always accompanied by the development of the clinical symptoms presented general poisoning pathogens which are processes that take place in the body, so that at this stage of your clinical check of a special type of this condition is practically impossible.
Chronic during worm invasion of the humans have a great variety of clinical manifestations, the intensity and the specificity of which depends directly on the localization of the pathological process of concentration of the worms, and the characteristics of their means of subsistence, as well as the possible development of the special of the defeat.
All of the worms, the promoters of gut development of the invasion sooner or later lead to the formation of the types of violations, that are the cause of digestive disorders, as well as violations of suction helpful nutrients and vitamins, mineral substances. In the long process of invasion in the human body accumulate the products of the vital activity of the worms, which inhibit the multiplication of components of the normal intestinal microflora, leading to the violation of work of the machine. Therefore, human beings create the conditions for the development of chronic diseases of the bacterial diseases.
Different forms of worm invasion accompanied by several periods of occurrence bright symptoms. So, to the worms is characteristic of long-latent for, and the clinical picture living with roundworms, on the contrary, makes his debut since the first days worm invasion. Most of the worms that invade the human body, cause the common development of rash, lymphadenopathy, hepatosplenomegaly, myalgia and arthropathy. During the examination of a patient suffering from worms, you must pay much attention to the complaints of the person and the data of the clinical examination, as well as the majority of etiological options of this disease accompanied by the appearance of specific clinical markers that would enable at an early stage of the disease install accurate a diagnosis. An example of this clinical marker can be jaundice when opistorhoze, the swelling of the soft tissues when the trichinosis.
Chronic during this pathology is usually asymptomatic nature, except when in the body of the flatworm parasite of humans. For enterobiasis characteristic clinical marker of chronic of the current is the constant appearance of itching in the anal area.
Specific to clinical practice with the marker worm invasion is the onset of symptoms hemorrhagic colitis, while the other worm of the invasion characterized by the early onset of the anemia. The accumulation of the-type worms Ascaris in the lumen of the intestine becomes the cause of the development of obstructive mechanical intestinal obstruction, as well as shutter bile ducts.
Chronic worm invasion in almost all cases, causes the defeat of the liver parenchyma, gallbladder, which is accompanied by non-specific manner to the clinic of the hepatitis b and acute cholecystitis. Worm invasion of the man causes the formation of many cystic fluids of the structures in the different bodies that develop asymptomatic, however, which are differentiated by the tendency to the development of complications inflammatory accompanied by rupture of the capsule and the development of peritonitis. Long hronizatsii worm invasion of the human form the signs of astnico syndrome, which flows through vegetative-vascular type.
Recognized is the fact that worms can lead to the development of polymorphic clinical symptoms in man, therefore, a pivotal moment in the diagnosis is the combination of a careful collection of epidemiological monitoring of the history and application of laboratory tests in the parasites.
Diagnostic studies in the worm are of the utmost importance and should be held up to the time of the assignment of the drug regimen. Modern specialized laboratories allow you to in the short-term and faithfully not only to establish the fact of the presence of worms in the man, but also the identification of the parasite. Of all the resources available in the arsenal of the diagnostic laboratory methods specialists, it is accepted to divide into direct and more of the methodology.
The direct analysis of the presence of worms in the body of a person implies the performance of special techniques, whose goal is the detection of worm, or some product of its vital activity. Side laboratory techniques allow only to confirm the presence of secondary pathological changes that arise as a result of the presence of the worm in the human body.
The brightest direct representatives of the laboratory investigation is the special of the therapy (detection of an adult worm or its parts impaired method at the ready) and another of the therapy (the application of the methodology of the thick brush by the method of kato–miura, flotation and sedimentation, with the detection of eggs or larvae of the worms).
Immunological study of the presence of worms in humans began to be applied recently and consists in the use of the skin of the sample and of the indirect haemagglutination. Serological tests to the worms in the man's more often used as a marker of the efficacy of the therapy with medicines against worms. Also in the daily practice of physicians began to be introduced such laboratory methods for the diagnosis of how is the technique of R. follya and resonance tests, the application that allows you to accurately identify worms in man and in any stage of development of the pathological process.
In such worm infestations the man, as Echinococcus and alveolar the initial value in the diagnosis is the application of technical tools of visualization of the type of ultrasound, x-ray, and the computer spiral tomography.
In function of biological material for the study of the worm of the invasion, they used different natural selection of the person (fresh of the feces, the portion of the urine, duodenal contents, sputum, bile, rectal, blood, muscle tissue). Due to the highest prevalence of the forms of worm invasion often detected worms in human feces.
