Rapoport Nutrient Medium

Nutrient medium Rapoport

Rapport's nutrient medium is a medium in which Salmonella Escherichia and Proteus grow well. This nutritional system was founded by the doctor Dmitry Georgievich Rappoport. He first saw such microorganisms after working for a long time in an infectious diseases clinic, where sepsis developed very quickly and the mortality rate in these cases was close to 80%. As a result of constant research, he formulated and developed a number of methods for identifying and cultivating the pathogen, which allow the remaining patients to survive.

Initially, during the Second World War, the laboratory could only make nutrient media for blood, but Dmitry Rappoport did not give up. He began to look for suitable bacteria, and a military medical institution came to help in this matter. After the bacterium, flexingens pisciforma 336, was identified, we had to prepare our own strain of salmonella, which could live in such a nutrient medium. Gelatin was used as a solvent, and the composition of the medium was semi-liquid. It itself was used to take smears for the presence of dysentery bacteria from the intestines. All this was done in order to obtain material and conduct an analysis for the presence of microorganisms that caused infection in humans.
