Note that the numbers in parentheses , , etc. Giardii - so doctors call a type of parasites, which are Die Analyse ljamblii inwitro to Die Analyse ljamblii inwitro as lamblia. They are the causative agents of the disease. The causes of giardiasis and the ways of its transmission are what most respondents are interested in. After all, only knowing the cause and the source of infection, you can protect yourself and your loved ones, and in case of infection and fight the disease.
In the human body, lamblia cysts are ingested orally through the oral cavitythen they pass through the esophagus to the duodenum, where they undergo a procedure of vegetative, asexual, division. It is here that the individual passes into its mobile phase, called trophozoite. In the area of the small intestine, parasites are fixed on villi of its mucous layer, there they feed on substances obtained during the breakdown of human food.
During the period of entering the large intestine, the life cycle of the lamblia Die Analyse ljamblii inwitro completed and begins Die Analyse ljamblii inwitro the giardias from active organisms pass into passive, immobile forms - they again become cysts. The large intestine is an unfavorable environment for lamblia, so they "dress" in the shell, which is its protection.
Hence they, together with the calves, come out of the patient's body and are ready to infect others again. The life cycle Die Analyse ljamblii inwitro lamblia is closed. Together with the feces, up Die Analyse ljamblii inwitro nine hundred million cysts are prepared, ready for infection, whereas 10 to cysts are enough to lamblias have settled in the intestine of a healthy person.
At the same time, their high vital activity can be preserved, in a conserved form, for Die Analyse ljamblii inwitro whole year, calmly transferring low or high temperatures, drying out. Only cysts are able to survive in such conditions, the trophozoites, released together with the calves, die Die Analyse ljamblii inwitro this climate.
Passing in the large intestine into the phase of cysts, Giardia together with feces are removed from the sick person. Getting into the environment, giardias are again ready to infect animals or other people.
To protect yourself and your loved ones, you need to know how lamblia Die Analyse ljamblii inwitro transmitted to a healthy body. Doctors Die Analyse ljamblii inwitro epidemiologists voice three main ways of infection: contact-household, through food and through liquid.
It turns out that lamblia in its active phase in the form of trophozoite is not contagious, because it is not able to survive in adverse conditions of the intestine of a person or animal and the environment. You can get infected only by cysts, inactive form of lamblia, this phase of lamblia is invasive. How do you get lamblia? Invasion occurs either directly from a sick person to a healthy, directly contact-household way, or through dirty unwashed hands, people who neglect basic rules of personal hygiene.
It should be noted that the main owners of parasites are animals: cats, dogs, mice, deer and others. The person, mainly, "catches this infection" from domestic and wild cats, which are home and mobile peddler of parasites.
That is, if we summarize the available information, the main sources and spreaders of the parasitic microflora, called lamblia, is the infected person and the sick animal.
The size of this parasite is more than modest and it is almost impossible to see it with the naked eye. Parameters of lamblia 18 per 10 microns length and width of the parasitethis individual has four pairs of antennae. This question is easy to answer, in the human body, parasites get orally, that is, through the mouth.
But the way this happens depends on the environment in which the parasite is found. This is an inactive, immobile phase of lamblia, but it allows the parasite to maintain its viability in difficult environmental conditions. Cysts of lamblia have an oval, slightly pear-shaped shape. Geometric parameters of the specimen can vary: Die Analyse ljamblii inwitro the length from 10 to 16 microns, in width from 6 to 10 microns.
The vegetative form of the parasitizing microorganism is localized, mainly in the small intestine, duodenum, urinary bladder, urinary tract. But after Die Analyse ljamblii inwitro parasite descends into Die Analyse ljamblii inwitro large intestine, it is transformed into cysts - microorganisms are covered with a kind of cocoon-shell, which protects them from the difficult conditions of the colon Die Analyse ljamblii inwitro the environment.
It is the cysts that are released from the infected organism along with the calves into the environment. When the cyst is again in the living organism, reaching the stomach, its membrane dissolves and the lamblia passes into another vegetative stage. Cysts of the immature stage have Die Analyse ljamblii inwitro nuclei, which are located together with a spiraling folded flagellate apparatus in the cytoplasm, while the "matured" parasite owns four nuclei.
With a visual inspection of the microorganism through the microscope, its coating is perfectly visible, it has a clear limiting contour dividing it with protoplasm, which is a distinctive feature of this type of parasite from other simple intestinal microorganisms. The stage of cysts is endowed with distributive functions. In a humid environment, under unfavorable climatic conditions, individuals in this form are not able to lose their viability for two to two and a half months.
In the hot summer period, this Die Analyse ljamblii inwitro does not die in wastewater until three to four months. On the surface of food, these microorganisms can live for several hours, and in the case of a humid environment, then up to several days. To chlorine, which is used for cleaning and disinfection of drinking water, lamblia are absolutely unresponsive. Diagnosis of Giardiasis includes the analysis of feces and a clinical study of blood. This is how you can find Die Analyse ljamblii inwitro or cysts of lamblia in the feces, and antibodies in the human blood plasma.
In the feces of the study to find the vegetative form of lamblia is problematic enough, here you can find only cysts. Die Analyse ljamblii inwitro this case, cystogenesis is represented by two periods: the maturation period, which can last up to two weeks and the time of maximum activity. It is difficult to detect giardia in a dense fecal mass, it is not easy to Die Analyse ljamblii inwitro them in warm feces, since the lamblias Die Analyse ljamblii inwitro form does not survive in such an environment, passing into cysts.
Diuretics, effective diuretics, can increase the chances of finding lambliasis. Their reception stimulates intestinal peristalsis, which contributes to an increase in the probability of detection of the parasite. If there is a suspicion of infection, physicians, usually for confirmation, are assigned two analyzes, especially in the case of diarrhea.
Increase the detection capabilities with a special medical device Paraser, which concentrates parasitic microorganisms. The principle of its operation is quite simple. A formalin-ether mixture is introduced into a Die Analyse ljamblii inwitro small container test tube.
Sterile spatula take a little feces for analysis, enough volumes with a pea. The container is screwed with a lid and the contents are well mixed. In this state, the sample can be stored at room temperature throughout the day, but no more. The tube is then placed in a medical centrifuge and scrolled at high speed about rpm. Centrifugal forces cause the cysts to pass through the filter and accumulate at the bottom of the tube, in a conical compartment. The concentration of microorganisms is most maximal in the upper layers of fine-dispersed deposits.
Almost a third of the world's population are carriers of such a parasite as lamblia, and do not even know about it. This microorganism "chose" for life the Die Analyse ljamblii inwitro intestine of man and animal namely animals, mainly, representatives of the family of felines are the main masters of this parasite.
Getting into the human body, Giardia does not cause him any discomfort. Hence a natural question emerges: Are lamblia dangerous?
Physicians answer him unequivocally. If the body of an adult human or child has a Die Analyse ljamblii inwitro high immune defense, then the body of a patient who has been subjected to aggression from harmful microorganisms is able to cope independently with the aggressor. The only officially registered disease associated with lamblias, doctors diagnosed as pathological changes to which the duodenum is exposed.
It is called lambliosis enteritis. In most cases, this disease passes by itself. If the immune system is weakened and unable to respond adequately to aggression, the colonization of the organism of a patient with a pathogenic flora can lead to intoxication.
In rare cases, giardiasis can cause chronic enteritis. This disease is expressed in a constant sluggish process of inflammation, which is localized in the small intestine.
Ultimately, this development of the disease leads to complete or partial atrophy of the intestinal mucosa. In this case, the affected part can be subjected to such parts: duodenum inflammatory process in this area is called duodenitisileum ileitis or small intestine jejunitis. But nevertheless, mainly the inflammation captures the entire intestinal mucosa, therefore colitis or gastritis can also join it. Physicians distinguish two periods of the development cycle of lamblia: Die Analyse ljamblii inwitro or cysts, and mobile or stage of vegetative existence.
Active and inactive species of Giardia and form a complete life cycle of the parasite. The first stage - motionless - is called a cyst. Due to its protective shell, the parasite is able to transfer without any consequences the complex climatic and biochemical features of the intestinal biome and the environment. Under this shell is still completely unformed trophozoite. It is in Die Analyse ljamblii inwitro form that lamblia stands out from the affected organism and waits for a convenient opportunity to get into the healthy organism of the "new owner".
That is, it is thanks to the cysts that the microorganism is able to spread and infect all large areas. Trophozoite is an active, vegetative phase in the development of Giardia. After hitting the cyst in the stomach, under the influence of gastric secretion, the membrane splits. The updated individual passes into the active phase. During this period it has a pear-shaped shape and dimensions are slightly larger than in the cyst period. It is in this form that giardiasis causes maximum damage to the body.
Giardii move, actively eating the products of food decay, while they are able to disrupt the cellular structure of the intestinal mucosa.
As a result of their activities: there is a malfunction in the intestine, signs of dysbiosis appear, the probability of penetration of pathogenic microflora increases. In this form they grow and pass a period of direct division most of this process occurs in the duodenum.
The life cycle Die Analyse ljamblii inwitro defined by several divisions. Giardia intestinalis - this Latin name denotes lamblia intestinal - a type of flagellate protozoa, which are the causative agents of a parasitic disease affecting the human intestine, many birds and other mammals.
This kind of parasites is also called Lamblia intestinalis, Giardia lamblia or Giardia duodenalis. This simplest parasite is called a traveler's diarrhea, as it is found by about five percent of people returning from a Die Analyse ljamblii inwitro trip, especially after visiting countries in the tropical zone. Depending on the biophysical characteristics of the organism of the infected person, the disease can be asymptomatic in one case, whereas in another manifestation may be so significant that a severe form of diarrhea with malabsorption is observed.
In some areas, the defeat of Die Analyse ljamblii inwitro population by this parasite, especially small children up to five yearsis close to one hundred percent.
