To specific diseases refer to the parasites. They cause particular pests, adapted to life within or on the human body, they feed and reproduce in him or with his help. The man can be to the pests such as intermediate and final master (that is, in the body develop the eggs and the larvae or adult specimens). Depending on the type of pest and location of the lesion, it can highlight a lot of diseases caused by them. More often meet in helminthiasis — diseases that are the result of the parasitism of special types of worms.
Pests: the different types of worms in the body
The largest group of parasites that can live in the body of a man, is the different types of worms, such as flat and round. Their refers to a group of diseases that doctors call it the name of "helminthiasis". Each parasite of this group has its ways and the ways of infection, the characteristics of the life cycle and the development of clinical manifestations and the methods for its treatment. In addition, each parasite is unable to because of their life-cycles, to give special complications. The most common parasites that can hurt people, are ossiuri and ascaris, trichinella, porcine or bovine taenia.
The types of parasites and the characteristics of the current infection
If you have indirect signs of infection of the helminths, it may be assumed that the man in that body lives one of the types of parasites. However, the treatment was effective and proper, it is important to know the types of parasites and what organs and systems, their amazed. For this it is important to perform a comprehensive examination, and pass a series of exams. Why is it necessary?
First of all, it is important to remember that the different types of parasites that live in the body of the host in the degree of larvae (if person — to-intermediate their master's or Mature specimens (if the final). In this regard, the therapeutic effects depending on what stage the parasite worm, they can be different, as well as habitat for the parasite.
These types of parasites, such as echinococcus, for human beings are dangerous in the larval stage. The larvae in the form of rounded capsules-cysts full of liquid toxic, affecting lungs, liver, kidneys, or brain. Inside of these organs in the course of many months or years of growth, hydatid cysts, inside of which lie the larvae. But these types of parasites, such as ossiuri, live in the body in the form of Mature specimens. The females exit the rectum in order to save millions of falling eggs with the feces in the environment.
Depending on the type of parasites, and the reactions of the body on them, localize the lesion, the response of the organism clinical manifestation range from asymptomatic until cast and heavy, until his death. It is also worth remembering that there are options and mixed-infection, when the body of a time, even the species of parasites.
As they drop the parasites in the body
Methods of penetration of the parasites in the body can be different. Often the infection occurs when the body of a man to penetrate the eggs of the parasites with different products or with water, with dirty hands, but also through the damaged skin, stings of insects. Often the eggs of the worms persist for a long period in the form of eggs in the soil, in the water or on the surfaces of the objects. Enter the body through the hands, food or not passed due to the treatment of water, there occurs the penetration of parasites in the body, where the eggs quickly matured, and out of the larvae (the intermediate options of the parasite), or mature specimens.
It is important to remember that parasites in the body cause serious damage, even if there are no obvious signs of defeat. First of all, they eat of his master, depriving him of part of the nutrients, vitamins and minerals. In addition, the parasites in the body can drastically increase Allergy the body, over-excite the immune system, which is a threat to the spontaneous development of the skin and other allergic reactions previously it is usual to products and substances.
The body does not remain indifferent to the penetration into it the worms, especially if it is soft tissue and internal organs. So, in the muscles and in the tissues that form protective inflammatory capsules, which cleanse the parasite from the tissues healthy. This leads to the formation of cysts and parasitic diseases, are often full of waste products of hearts. The body often reacts to the introduction of parasites, disorders of the digestive functions, if it is the worms that live in the intestine, appetite changes, weight changes and exacerbation of chronic diseases.
It's not worth to think that the problem of parasites is only relevant for people in the poorest countries, and regardless relating to hygiene. The prevalence of helminths affects, is comparable, according to the WHO, with such diseases as SARS and influenza. So, regularly there is a need to pass the exam, and the elimination of parasites.
In need of an analysis of the parasites
Many patients mistakenly believe that once the analysis of parasites (cal or a swab perianal), which showed a negative result and is a guarantee of the absence of parasites in the body. However, in reality it is not so, and so the result says nothing. In the first place, the parasites may be extraintestinal who live in other organs and tissues, and then their eggs or larvae, just don't fall in the stool.
In the second place, at the time of the sampling analysis on the parasites, may represent a period of the parasite's life, when not yet or already not spawn. And in the third place, there is the risk of non-compliance with all the conditions for the analysis, and then the eggs are not in the sample, which was granted.
So, if you are talking about intestinal worms, when it is assigned to the analysis of parasites, the feces give up a triple with a certain interval, to confirm the presence or absence of parasites. This is the only technique with a probability of 90% can speak either to confirm or refute the diagnosis.
The most indicative in this sense, the analysis of parasites taken from a vein, with the determination of antibodies, or still worms. If the body is put in contact with the parasite more recently, will take place in the antibodies of class M to him, that will lead to a pathogen. Prolonged parasite will still give antibodies and other classes.
