German scientists have created a new method for detecting bacteria that cause diarrhea.

Most fatal cases are associated with pathogenic microorganisms entering the gastrointestinal tract along with dirty water or food. Identification of the bacterium or virus that caused the disease is extremely difficult process, according to the Internet publication for girls and women from 14 to 35 years old Pannochka. net The new diagnostic tool finds short repeating segments of DNA in the genome of the bacterium, enrolling it to a specific strain. In addition, the method makes it possible to identify the mechanism for the appearance of new species of bacteria.

Vibrio cholera is the most common causative agent of the disease. Dangerous are strains producing a toxin that affects the walls of the intestine.

The new method makes it possible to construct characteristics and find differences between hundreds of species of microorganisms. For the analysis, scientists use short DNA fragments marked with different colors. Each colored fragment corresponds to a repeating segment. Then the scientists calculate the number of repetitions.
