Stool culture is defined as a type of bacteriological analysis which is carried out on the feces, for this, techniques are used that promote the development of microorganisms that are present in the fecal samples previously taken, using a gelatinous substance, allowing this shape identifies the pathogens (bacteria, larvae, worms, amoebas, etc.) that may be responsible for causing any disease.
This type of examination is frequently used to identify pathogens in the feces that are generally responsible for the digestive system causing some infections in the digestive tract and diarrhea. Among the main bacteria that a stool culture could detect are salmonella, Escherichia coli, Shigella, Vibrio cholerae, among others. The presence of these agents in the body can generate symptoms of different types such as upset stomach, fevers, diarrhea, vomiting, etc.
In order to carry out this test, it is necessary that the sample be taken first, which must be free of substances that alter it, such as urine or other toilet paper. The stool sample can be collected using a plastic bag for this, which can be placed in the toilet, or failing that, a special tool for collection, then it must be placed in a previously sterilized container and sent to the laboratory. soon as possible. After this, in the laboratory, we proceed with the culture of the feces in a round container, where the microorganisms must grow, then the growth of it must be monitored and then it is identified by using microscopes or failing that. different staining techniques are used.
After all the procedure described above has been carried out, the laboratory officer in charge must make a report detailing the result of said analysis, that is, in said report it must indicate whether the levels of the saprophytic flora are normal or no. Normally, normal results should indicate concentrations of Gram-negative bacteria between 50 and 70 percent, as well as 30 to 50 percent of Gram-positive bacteria, without the presence of red blood cells and white blood cells.
