Analysis of stool for dysbiosis
Analysis of feces for dysbacteriosis is a method of laboratory research that allows to detect changes in normal types of bacterial composition of the intestine and skin.
As is known, disturbance of the balance of the intestinal microflora develops for various reasons. Among them, and taking antibacterial drugs, immune disorders, improper diet and so on.
The analysis of feces for dysbiosis is carried outdoctor-gastroenterologist. The specialist identifies all the deviations in accordance with predisposing factors, the age of the patient, the nature of the disease and its clinical manifestations. The result of the study allows you to prescribe a treatment or, in case of doubt, additional diagnostic measures.
The analysis of a feces on a dysbacteriosis gives the chancedetermine and give an estimate of the concentration and ratio of bifidobacteria, E. coli (Escherichia coli), lactobacilli with bacteria, opportunistic staphylococci, enetobacteria, fungi, clostridia, as well as pathogenic microorganisms Salmonella, Shigella.
Indications for the purpose of the study may be:
- Stool disorders (constipation, diarrhea);
- a feeling of discomfort in the abdomen;
- intestinal infections;
- flatulence (bloating);
- intolerance of certain products;
- prolonged hormonal and antibacterial therapy;
- allergic reactions;
- rashes on the skin.
The analysis of feces for dysbacteriosis is used to determine the nature of disturbances in normal intestinal biocenosis.
Before the study is recommended forFor several days, do not take laxatives, do not use rectal suppositories, vaseline and castor oil. When collecting the analysis, the feces are placed in a sterile container. In this case, you should strictly monitor that it does not get urine. Antibiotics should be discontinued no less than twelve hours before the procedure. Do not put an enema before collection of stool. Do not take barium. The optimal volume of material for the study is 10 ml. Storage should be carried out in the cold, delivered to the laboratory no later than three hours after collection.
Analysis of feces for dysbiosis. Explanation
The following results should be considered valid:
- Escherichia coli (E. coli) typical 10,8;
- bifidobacteria - from 10 to 10.9;
- pathogenic intestinal microbes are normally absent;
- Nonfarming bacteria - 10,4;
- Microbes of the genus Proteus - less than 10.2;
- lactose-negative colibacillus - less than 10.5;
- enterobacteria (conditionally pathogenic) - less than 10,4;
- enterococcus - 8 - 10,5;
- hemolytic Escherichia coli (E. coli) is normally absent;
- hemolytic staphylococcus is absent;
- saprophytic, epidermal staphylococcus - 10,4;
- Clostridium - no more than 10,5;
- lactobacilli from 8 to 10.7;
- Yeast-like fungi - not less than 10.3;
- Bacteroides - less than 10.7.
Analysis of the intestinal dysbacteriosis is carried out withthe purpose of determining the level of biochemical indicators. These include, in particular, the metabolites of volatile acids (propionic, acetic, butyric acid) produced by microorganisms inhabiting the gastrointestinal tract.
All sorts of pathologies on the part of the liver,stomach, and also various parts of the intestine (thin, thick) provoke a change in the microflora. Accordingly, biochemical parameters also change. The determination of the acid spectrum allows one to evaluate the disease and determine its localization.
In the study of metabolites, the gas-liquid (chromatographic) method is used. With its application it is possible to adequately assess the state of the flora not only of the intestine but also of the oral cavity.
Study of feces allows not only to determine the nature of the changes occurring, but also to identify the underlying disease that provoked dysbiosis.
