Bordet-Gengou Reaction

Bordet-Gengou reaction is a method for detecting and identifying microorganisms based on their ability to ferment certain carbohydrates. This method was developed by French scientists Jean Bordet and Olivier Gengou in 1928.

The Bordet-Gangou reaction is based on the use of special media containing certain carbohydrates (for example, mannitol), which are substrates for microorganisms. If a microorganism is capable of fermenting a given carbohydrate, then it will grow on this medium and produce gas formation.

To perform the Bordet-Gengou reaction, a sample of the material being tested (for example, sputum, feces, or blood) must be placed on a special medium. Then you need to add indicator paper, which changes its color depending on the presence or absence of gas formation. If gas forms on the medium and the indicator changes color, this indicates the presence of microorganisms.

The use of the Bordet-Gengou reaction is important for the diagnosis of various infectious diseases, such as tuberculosis, pneumonia, typhoid fever, dysentery, cholera and others. In addition, this method is used to determine the sensitivity of microorganisms to antibiotics and other drugs.

Thus, the Bordet-Gengou reaction is an important method for the diagnosis and control of infectious diseases.
