Nowadays, more and more people are faced with various diseases, including infectious ones, so it is necessary to have diagnostic tools on hand to detect the disease in the early stages. One such tool is the N3 GRM nutrient medium, which is used to identify microbes in various biological samples. This medium is intended for the cultivation of pathogens of gonorrhea, tuberculosis, staphylococci and other microorganisms. It can be used both for diagnosing diseases in medicine and for research in laboratories.
